Description

本発明は電力制御システム、電力制御装置及び電力制御方法に関する。 The present invention relates to a power control system, a power control apparatus, and a power control method.

電力供給元の発電設備などが何らかの原因により停止するなどし、大幅な電力の供給量が低下する可能性がある。電力供給量の不足が明らかな場合は、電力供給元としての電力会社で、事前予告した一部地域全体の電力を停止させるなどの方法を取ることによって、大規模停電を回避している。しかしながら、電力停止の地域で生活する人にとっては、電気機器を使用できなくなるなど、大きな負担となってしまう。その解決策の一つとして、特開２００２−１０５３２（特許文献１）に示される技術がある。特許文献１における技術では、電力供給元から電力の削減要求を受ける集中計算センターにて、リアルタイムに消費電力を収集し、電力削減要求を各契約者（住宅、ビル、工場など）の電力を制御するコントローラに指示することで、省電力化を実現している。その際に、電力を制御する範囲を地域に応じていくつかのグループに分割し、各グループに時間単位ずつ電力削減量を指示することによって、ピーク電力の削減を行っている。 There is a possibility that the power supply facility of the power supply source will be stopped for some reason and the amount of power supply will be greatly reduced. When the shortage of power supply is obvious, the power company as a power supply source avoids large-scale power outages by taking measures such as stopping the power supply in some areas as a prior notice. However, for people living in areas where power is stopped, it becomes a heavy burden, such as the inability to use electrical equipment. As one of the solutions, there is a technique disclosed in Japanese Patent Laid-Open No. 2002-10532 (Patent Document 1). In the technology in Patent Document 1, power consumption is collected in real time at a centralized calculation center that receives a power reduction request from a power supply source, and the power of each contractor (house, building, factory, etc.) is controlled based on the power reduction request. By instructing the controller to perform power saving. At that time, the power control range is divided into several groups according to the region, and the peak power is reduced by instructing each group on the amount of power reduction for each time unit.

特開２００２−１０５３２号公報JP 2002-10532 A

特許文献１の技術では、同一グループ内の契約者に対して同量の電力削減量を要求する。これは特許文献１の前提とするシステムでは、消費する電力をすべて同一の優先度の電力として扱っているためである。しかしながら、一般に消費する電気機器にはそれぞれ優先度が存在すると考えられる。例えば、医療機関などでは、人命にかかわるなどの理由により停止できない電力がほとんどを占める。一方で各家庭における使用電力は、優先度の低い余剰電力が大半を占める。ただし、家庭においても、宅内医療機器などを使用していれば、他の家電製品は停止させても、優先度の高い医療機器はできる限り停止させたくないなどの状況が想定される。このように電力の使用現場では細かい優先度が存在するが、上記、特許文献１の技術では、各グループ内の契約者に対しては同一の電力削減を指示するため、優先度を考慮した電力の削減ができなかった。
また、特許文献１では各契約者からの消費電力をリアルタイムに集中計算センターへ通知する形態となっており、集中管理センターが全ての情報を一元管理する。その場合、扱う契約者の数が増加するに伴い、管理側の設定などが煩雑となってしまう課題がある。例をあげると、特許文献１では、あらかじめ契約者ごとにグループ分けの設定を実施しておく必要があり、契約者の追加や削除などのたびにグループ分けの設定が必要となってしまうという課題がある。
以上の点に鑑み、本発明は、システム全体として優先度の低い電力から電力を削減し優先度の高い電力を確保する電力制御システムを実現することを目的とする。 In the technique of Patent Document 1, the same amount of power reduction is requested from the contractor in the same group. This is because the system based on Patent Document 1 handles all consumed power as power having the same priority. However, it is generally considered that each electric device to be consumed has a priority. For example, in medical institutions, etc., most of the electric power cannot be stopped due to reasons related to human life. On the other hand, surplus power with low priority occupies most of the power used in each household. However, even in homes, if home medical devices are used, it is assumed that even if other home appliances are stopped, it is not desirable to stop high-priority medical devices as much as possible. As described above, there is a fine priority at the site where power is used. However, in the technique disclosed in Patent Document 1, the contractor in each group is instructed to reduce the same power. It was not possible to reduce.
Moreover, in patent document 1, it is the form which notifies the power consumption from each contractor to a centralized calculation center in real time, and a centralized management center manages all the information centrally. In this case, there is a problem that the setting on the management side becomes complicated as the number of contractors to be handled increases. For example, in Patent Document 1, it is necessary to set grouping for each contractor in advance, and it is necessary to set grouping every time a contractor is added or deleted. There is.
In view of the above points, an object of the present invention is to realize a power control system that reduces power from low-priority power as a whole system and secures high-priority power.

上記課題を解決するため、本発明では、宅内や社内で使用される電気機器に優先度を設定し、それらの電気機器が消費する電力を優先度別に収集する。ここで優先度とは電力削減時の優先度のことで、削減時には優先度が低い機器から順に削減対象となる。電力需要がひっ迫するなどした場合は、その収集した優先度別の消費電力を元に優先度の低い電力から削減できるよう各地域や家庭などの削減量を計算する。これにより、優先度を考慮した電力制御を実現することが可能である。また、収集する情報および処理方法を階層的に制御する電力制御の装置を配置する。これにより、最上位の装置ではシステム全体の消費電力を収集可能であり、また、特定の階層において優先度を考慮した消費電力の制御も簡易に実現することが可能となる。 In order to solve the above problems, in the present invention, priorities are set for electrical devices used in the house or in the office, and the power consumed by these electrical devices is collected by priority. Here, the priority is a priority at the time of power reduction. At the time of reduction, the priority is a reduction target in descending order of devices. When the power demand becomes tight, the amount of reduction in each area or home is calculated so that the power can be reduced from the low priority based on the collected power consumption by priority. Thereby, it is possible to realize power control in consideration of priority. In addition, a power control apparatus that hierarchically controls the information to be collected and the processing method is arranged. As a result, the power consumption of the entire system can be collected in the highest-level device, and the power consumption control considering the priority in a specific hierarchy can be easily realized.

（実施例１）
１．システム構成
図１を参照し、本実施例におけるシステム構成を説明する。図１に示す本実施例における電力制御システムはピラミッド型の階層構造をとる。本実施例におけるピラミッド型の電力制御システムは、最上位の電力制御装置（第１電力制御装置）１００を頂点として、任意の台数、任意の階層をとる下位の（最上位の電力制御装置と機器制御装置の間に配置される）電力制御装置（第２電力制御装置）１００と、実際に電力を消費する複数の機器１０２と、それらの機器１０２の電源状態を制御する複数の機器制御装置１０１とを備える。本実施例では、図１に示すピラミッド型の階層構造により、各階層で消費電力の収集、および抑制電力の伝達を分散的に行うことで、消費電力の制御を行う。ここで、本実施例における消費電力の収集とは、ある階層において下位に存在する複数台の装置（例えば、ひとつ下の階層の装置）から、消費電力の通知を受け、その階層における総消費電力および優先度別の消費電力を求め、上位の装置（例えば、ひとつ上の階層の装置）にその結果を通知することである。また、抑制電力の伝達とは、上位装置から消費電力の上限を通知された場合に、その階層における優先度別消費電力を基に、下位に存在する各装置（例えばひとつ下の階層の装置）の消費電力の上限を求め、その装置毎の消費電力の上限をそれぞれの装置に通知していくことである。 Embodiments of the present invention will be described with reference to the drawings.
Example 1
1. System Configuration A system configuration in the present embodiment will be described with reference to FIG. The power control system in this embodiment shown in FIG. 1 has a pyramid type hierarchical structure. The pyramid type power control system according to the present embodiment is a lower-order (top power control apparatus and device having an arbitrary number and an arbitrary hierarchy with the highest power control apparatus (first power control apparatus) 100 as a vertex. A power control device (second power control device) 100 disposed between the control devices, a plurality of devices 102 that actually consume power, and a plurality of device control devices 101 that control the power supply state of these devices 102 With. In this embodiment, the power consumption is controlled by collecting the power consumption and transmitting the suppression power in each layer in a distributed manner using the pyramid-type hierarchical structure shown in FIG. Here, the collection of power consumption in the present embodiment means that a power consumption notification is received from a plurality of devices (for example, devices in the next lower layer) existing in a lower level in a certain hierarchy, and the total power consumption in that hierarchy. In addition, the power consumption for each priority is obtained, and the result is notified to a higher-level device (for example, a device in the upper hierarchy). In addition, when the upper power device is notified of the upper limit of power consumption, the transmission of the suppression power is based on the power consumption according to priority in the hierarchy (for example, the device in the lower hierarchy). The upper limit of the power consumption is obtained, and the upper limit of the power consumption for each device is notified to each device.

本実施例の一態様によれば、実際に電力を消費する機器１０２は、例えば、各家庭や、工場、病院、ビルなどで使用される照明、エアコン、ＴＶなどの電気機器などである。本実施例におけるこれらの機器１０２は機器制御装置１０１により、電源ＯＮ／ＯＦＦなどの状態を管理され、また、機器の消費電力を定期的に機器制御装置１０１に通知する機能を持つ。
機器制御装置１０１は、各家庭やビル、工場などに設置され、機器１０２を制御し、各機器１０２の消費電力を収集、および抑制電力の伝達を行う装置である。また、電力制御装置１００は、例えば一定地域ごとに設置され、配下の各機器制御装置１０１の消費電力を収集、および抑制電力の伝達を行う装置である。あるいは、電力制御装置１００は、一定地域毎に設定された電力制御装置１００をさらに集約し、広範囲な地域の消費電力を収集、および抑制電力の伝達を行う装置である。最終的には最上位の電力制御装置１００によりシステム全体の消費電力を収集することが可能である。また、最上位の電力制御装置１００に消費電力の上限を通知（設定）することで、システム全体に抑制電力を伝達していくことが可能である。
本実施例における電力制御システムでは、最下位の機器１０２から最上位の電力制御装置１００に対して、消費電力を通知し、最上位の電力制御装置１００により、システム全体の消費電力を収集するステップと、最上位の電力制御装置１００から、下位の階層毎の消費電力の上限を算出し、各階層の装置にその消費電力の上限を通知していくステップにより、システム全体として優先度を考慮した電力の削減を実現する。 According to one aspect of the present embodiment, the device 102 that actually consumes power is, for example, an electric device such as a lighting, an air conditioner, or a TV used in each home, factory, hospital, building, or the like. In the present embodiment, these devices 102 are managed by the device control device 101 in a state such as power ON / OFF, and have a function of periodically notifying the device control device 101 of the power consumption of the device.
The device control device 101 is a device that is installed in each home, building, factory, etc., controls the device 102, collects power consumption of each device 102, and transmits suppressed power. Moreover, the power control apparatus 100 is an apparatus that is installed, for example, for each predetermined region, collects power consumption of each of the subordinate device control apparatuses 101, and transmits suppression power. Alternatively, the power control device 100 is a device that further aggregates the power control devices 100 set for each certain region, collects power consumption in a wide range, and transmits suppressed power. Eventually, the power consumption of the entire system can be collected by the highest power control apparatus 100. Further, by reporting (setting) the upper limit of power consumption to the highest-level power control apparatus 100, it is possible to transmit suppressed power to the entire system.
In the power control system according to this embodiment, the lowest power device 102 notifies the highest power control apparatus 100 of the power consumption, and the highest power control apparatus 100 collects the power consumption of the entire system. And calculating the upper limit of power consumption for each lower tier from the highest power control apparatus 100 and notifying the upper limit of the power consumption to the devices of each tier, considering the priority as a whole system Realize power savings.

２．電力制御装置
図２を参照し、本実施例における電力制御装置１００を説明する。図２に示す電力制御装置１００では、一つの上位装置２１０と複数台の下位装置２２０〜２２２の間での消費電力の収集、および抑制電力の伝達を行う。最上位の電力制御装置１００を除いて、電力制御装置１００の上位装置２１０は上位の電力制御装置１００である。最上位の電力制御装置１００の上位装置は、最終的に総消費電力の結果を通知され、システム全体の消費電力の上限を指定する管理側の装置である。また、電力制御装置１００の下位装置２２０〜２２２は機器制御装置１０１または下位の電力制御装置１００である。電力制御装置１００は下位装置２２０〜２２２からの消費電力の通知を受け、下位装置全体の総消費電力および優先度別消費電力を上位の電力制御装置１００に通知する。また、上位装置２１０から消費電力の上限を通知されると、消費電力および優先度別消費電力から下位装置２２０〜２２２それぞれの消費電力の上限を計算し、下位装置２２０〜２２２（下位の電力制御装置１００あるいは機器制御装置１０１）へ通知する。
最上位の電力制御装置１００の構成も、図２に示すのと同様であるが、上位装置への消費電力通知は不要である。また、上位装置からの消費電力の上限通知の変わりに、消費電力の上限値が、例えば操作者の操作により入力部から入力される。なお、消費電力の上限値は、電力の供給量を管理する装置などの適宜の装置から入力されてもよい。
図２に示す電力制御装置１００は電力制御機能部２００を持つ。電力制御機能部２００には、電力記憶部２０１、電力収集制御部２０２、電力分散制御部２０３、通知タイマ２０４を有する。 2. Power Control Device With reference to FIG. 2, a power control device 100 in the present embodiment will be described. In the power control apparatus 100 illustrated in FIG. 2, power consumption is collected and suppression power is transmitted between one upper apparatus 210 and a plurality of lower apparatuses 220 to 222. Except for the highest-level power control apparatus 100, the higher-level apparatus 210 of the power control apparatus 100 is a higher-level power control apparatus 100. The host device of the highest-level power control device 100 is a management-side device that is finally notified of the result of total power consumption and specifies the upper limit of power consumption of the entire system. The lower devices 220 to 222 of the power control device 100 are the device control device 101 or the lower power control device 100. The power control apparatus 100 receives power consumption notifications from the lower apparatuses 220 to 222 and notifies the upper power control apparatus 100 of the total power consumption and priority-specific power consumption of the entire lower apparatus. When the upper limit of power consumption is notified from the host device 210, the upper limit of power consumption of each of the lower devices 220 to 222 is calculated from the power consumption and the power consumption by priority, and the lower devices 220 to 222 (lower power control) are calculated. Notification to the device 100 or the device control device 101).
The configuration of the highest-level power control apparatus 100 is the same as that shown in FIG. 2, but it is not necessary to notify the host apparatus of power consumption. Further, instead of the upper limit notification of power consumption from the host device, the upper limit value of power consumption is input from the input unit by the operation of the operator, for example. Note that the upper limit value of power consumption may be input from an appropriate device such as a device that manages the amount of power supply.
The power control apparatus 100 illustrated in FIG. 2 has a power control function unit 200. The power control function unit 200 includes a power storage unit 201, a power collection control unit 202, a power distribution control unit 203, and a notification timer 204.

電力制御機能部２００における電力収集制御部２０２の処理シーケンスを図４に示す。下位装置２２０〜２２２から周期的に通知される消費電力の通知は電力収集制御部２０２にて取得される。下位装置から消費電力の通知を受けた場合（Ｓ４０１）、電力収集制御部２０２は、電力記憶部２０１のエントリ毎の消費電力および優先度別消費電力を、取得した消費電力および優先度別消費電力に更新する（Ｓ４０６）。電力記憶部２０１の例を図７に示す。図７については後に詳述する。また、電力収集制御部２０２は、上位装置に周期的に消費電力を通知する間隔を、通知タイマ２０４から通知される。例えば、通知タイマ２０４が、所定間隔毎に消費電力通知の指示を電力収集制御部２０２に出力してもよい。本実施例においてシステム階層が下位の装置になるほど、上位装置に通知する消費電力の変動が激しく、上位装置になるほど平準化される。そのため、下位装置になるほど通知タイマの周期を短く設定し、上位装置になるほど通知タイマの周期を長く設定してもよい。例えば、機器ＯＮ／ＯＦＦなどにより収集する消費電力が変動する機器制御装置１０１では、よりリアルタイム性を持たせるため、１〜１０秒の短い周期で上位装置へ消費電力を通知する。しかしながら、最上位付近の電力制御装置１００では、収集する消費電力は平均化され、変動は少なくなると考えられる。そのため、１０分〜３０分周期での通知タイマを設定することが可能である。これにより、上位装置になるに従い、消費電力通知による電力収集制御部２０２の処理負荷を減少させることが可能である。電力収集制御部２０２が通知タイマから、消費電力通知の指示を受けた場合（Ｓ４０１）、電力収集制御部２０２は電力記憶部２０１に記憶された各下位装置の消費電力の合計と優先度別消費電力の合計を計算する（Ｓ４０２）。また、電力収集制御部２０２は、上位装置に通知する消費電力に対して、優先度別消費電力の補正が必要となった場合（Ｓ４０３）、実施例２で詳述する優先度別消費電力の補正を行い（Ｓ４０４）、上位装置へ消費電力通知を行う（Ｓ４０５）。例えば、消費電力の合計と、優先度別消費電力の合計を上位装置に通知する。なお、本実施例では、ステップＳ４０３、Ｓ４０４は省略できる。また、最上位の電力制御装置１００では、消費電力通知のステップＳ４０５は省略できる。
電力分散制御部２０３は、上位装置２１０から通知される消費電力の上限により、下位装置２２０〜２２２に消費電力の上限を通知する。電力分散制御部２０３の処理シーケンスを図５に示す。
電力分散制御部２０３は、上位装置２１０から消費電力の上限を通知された場合、電力記憶部２０１からエントリ毎の消費電力および優先度別消費電力を取得し（Ｓ５０１）、後述する方法により、エントリ毎（下位装置毎）の消費電力の上限を計算する（Ｓ５０２）。また、求めた消費電力の上限を各エントリに該当する下位装置毎に通知する（Ｓ５０３）。 A processing sequence of the power collection control unit 202 in the power control function unit 200 is shown in FIG. The power collection control unit 202 acquires power consumption notifications periodically notified from the lower devices 220 to 222. When a power consumption notification is received from the lower device (S401), the power collection control unit 202 uses the acquired power consumption and power consumption by priority for the power consumption and power consumption by priority for each entry in the power storage unit 201. (S406). An example of the power storage unit 201 is shown in FIG. FIG. 7 will be described in detail later. Further, the power collection control unit 202 is notified from the notification timer 204 of an interval for periodically notifying the host device of power consumption. For example, the notification timer 204 may output a power consumption notification instruction to the power collection control unit 202 at predetermined intervals. In this embodiment, the lower the system hierarchy is, the more the fluctuation of the power consumption notified to the higher-level device, and the higher the level of the higher-level device is leveled. Therefore, the notification timer cycle may be set shorter as the lower device is used, and the notification timer cycle may be set longer as the higher device is used. For example, in the device control apparatus 101 in which the power consumption collected by the device ON / OFF or the like varies, the power consumption is notified to the host device in a short cycle of 1 to 10 seconds in order to provide more real-time performance. However, in the power control apparatus 100 in the vicinity of the highest level, the collected power consumption is averaged, and the fluctuation is considered to be reduced. Therefore, it is possible to set a notification timer with a period of 10 minutes to 30 minutes. As a result, the processing load on the power collection control unit 202 based on the power consumption notification can be reduced as the host device becomes higher. When the power collection control unit 202 receives a power consumption notification instruction from the notification timer (S401), the power collection control unit 202 sums the power consumption of each lower-level device stored in the power storage unit 201 and consumption by priority. The total power is calculated (S402). Further, when it is necessary to correct the power consumption classified by priority for the power consumption notified to the higher-level device (S403), the power collection control unit 202 determines the power consumption classified by priority described in detail in the second embodiment. Correction is performed (S404), and power consumption notification is sent to the host device (S405). For example, the host device is notified of the total power consumption and the total power consumption by priority. In this embodiment, steps S403 and S404 can be omitted. In the highest-level power control apparatus 100, step S405 of power consumption notification can be omitted.
The power distribution control unit 203 notifies the lower devices 220 to 222 of the upper limit of the power consumption based on the upper limit of the power consumption notified from the upper device 210. A processing sequence of the power distribution control unit 203 is shown in FIG.
When notified of the upper limit of power consumption from the host device 210, the power distribution control unit 203 acquires the power consumption for each entry and the power consumption by priority from the power storage unit 201 (S501). The upper limit of power consumption for each (each lower-level device) is calculated (S502). Further, the upper limit of the calculated power consumption is notified to each lower device corresponding to each entry (S503).

３．消費電力計算方法
図７の表７００を参照し、電力収集制御部２０２における、上位装置へ通知する消費電力の計算方法について説明する。図７は、電力制御装置１００において、下位装置Ａ２２０、下位装置Ｂ２２１、下位装置Ｎ２２２の３つの下位装置から消費電力を通知された場合に、電力記憶部２０１に記憶される消費電力の例を示している。下位装置からは通知される消費電力として、下位装置において集計された消費電力の合計７０１と、例えば優先度ＡからＣに分けられた優先度別の消費電力７０２を通知されている。ここで、優先度ＡからＣの消費電力は優先度Ａが最も優先度が低く、優先度Ｂ、Ｃとなるにつれ、優先度は上昇するものとする。図７では下位装置Ａ、Ｂ、Ｎから通知された情報はそれぞれ下位Ａ７０３、下位Ｂ７０４、下位Ｎ７０５として示している。電力記憶部２０１には、下位装置を識別する適宜の識別子を記憶できる。例えば、下位装置Ａ２２０での消費電力は１０００万ｋＷであり、優先度Ａ、Ｂ、Ｃ毎の消費電力の内訳はそれぞれ３００万ｋＷ、２００万ｋＷ、５００万ｋＷである。電力制御装置１００では、下位装置から通知される消費電力の合計７０６を計算し、電力記憶部２０１に記憶する。また、消費電力の合計及び優先度別消費電力を上位装置へ定期的に通知する。なお、消費電力の合計は通知を省略してもよく、この場合上位装置は優先度別消費電力から消費電力の合計を求めることができる。電力制御装置１００は階層構造になっており、全ての電力制御装置１００でこの処理を行うことで、最上位の電力制御装置１００はシステム内の全ての消費電力と優先度別消費電力を把握することが可能である。 3. Power Consumption Calculation Method With reference to the table 700 in FIG. 7, the power consumption calculation method notified to the higher-level device in the power collection control unit 202 will be described. FIG. 7 shows an example of power consumption stored in the power storage unit 201 when the power control apparatus 100 is notified of power consumption from three lower-level devices A220, B221, and N222. ing. As the power consumption notified from the lower devices, the total power consumption 701 aggregated in the lower devices and the power consumption 702 for each priority divided into priority levels A to C, for example, are notified. Here, it is assumed that the priority A has the lowest power consumption of the priority levels A to C, and the priority level increases as the priority levels B and C increase. In FIG. 7, information notified from the lower devices A, B, and N is shown as a lower A 703, a lower B 704, and a lower N 705, respectively. The power storage unit 201 can store an appropriate identifier for identifying the lower device. For example, the power consumption in the lower device A220 is 10 million kW, and the breakdown of the power consumption for each of the priorities A, B, and C is 3 million kW, 2 million kW, and 5 million kW, respectively. In the power control apparatus 100, the total power consumption 706 notified from the lower apparatus is calculated and stored in the power storage unit 201. Also, the total power consumption and the power consumption by priority are periodically notified to the host device. Note that the notification of the total power consumption may be omitted, and in this case, the host device can obtain the total power consumption from the power consumption by priority. The power control apparatus 100 has a hierarchical structure, and by performing this process in all the power control apparatuses 100, the highest power control apparatus 100 grasps all the power consumption in the system and the power consumption by priority. It is possible.

４．消費電力分散方法
図７の表７１０を参照し、本実施例における電力制御装置１００の抑制消費電力の伝達方法について説明する。電力制御装置１００では上位装置２１０から、消費電力の上限を通知される。この消費電力の上限は、最上位の電力制御装置１００においては、例えばオペレータにより管理側の装置から指示される。また、下位の電力制御装置においては、上位の電力制御装置から指示される。電力分散制御部２０３では電力記憶部２０１から下位装置２２０〜２２２の消費電力を取得し、優先度の低い電力から電力を削減するよう下位装置２２０〜２２２それぞれの消費電力の上限を計算する。図７の表７１０では消費電力の合計６０００万ｋＷに対して、上位装置２１０から５０００万ｋＷの消費電力を上限とする通知を受けた場合の例を示している。この場合、電力制御装置１００では消費電力の上限を満たすために、１０００万ｋＷの電力を削減する必要がある。ここで、最も優先度の低い優先度Ａの消費電力の合計は表７００によると８００万ｋＷであり、優先度Ａの電力を削減するだけでは消費電力の上限を超えてしまう。残り２００万ｋＷの消費電力を次に優先度の低い優先度Ｂの消費電力から削減する必要がある。優先度Ｂの消費電力の合計は表７００によると２５００万ｋＷであり、２００万ｋＷ／２５００万ｋＷで優先度Ｂの消費電力の内８％（ここでは各々１６、４８、１３６ｋＷ）の消費電力を削減すればよいことになる。そのため、下位装置Ａ、Ｂ、Ｎにおいて優先度Ｂの消費電力を各８％削減することで、２００万ｋＷの消費電力の削減が可能である。これにより、各下位装置に対して優先度Ａ、Ｂ、Ｃの各消費電力から削減する消費電力７１３を求め、そこから下位装置２２０〜２２２に通知する消費電力の上限を計算する。電力分散制御部１００では、下位装置毎に求めた消費電力の上限７１４を、それぞれ下位装置２２０〜２２２へ通知する。通知を受けた下位装置２２０〜２２２では同様の処理を繰り返すことで、システム全体として優先度の低い消費電力から電力を削減した場合の消費電力を算出することが可能となる。なお、これ以外にも適宜の手法で優先度に基づく消費電力を削減してもよい。 4). Power Consumption Dispersion Method With reference to the table 710 in FIG. 7, a method for transmitting the suppressed power consumption of the power control apparatus 100 in the present embodiment will be described. In the power control apparatus 100, an upper limit of power consumption is notified from the host apparatus 210. In the uppermost power control apparatus 100, the upper limit of the power consumption is instructed from an apparatus on the management side by an operator, for example. In the lower power control apparatus, an instruction is given from the upper power control apparatus. The power distribution control unit 203 acquires the power consumption of the lower devices 220 to 222 from the power storage unit 201, and calculates the upper limit of the power consumption of each of the lower devices 220 to 222 so as to reduce the power from the power with low priority. A table 710 in FIG. 7 shows an example of a case where a notification with the upper limit of power consumption of 50 million kW is received from the host device 210 for a total power consumption of 60 million kW. In this case, the power control apparatus 100 needs to reduce power of 10 million kW in order to satisfy the upper limit of power consumption. Here, according to the table 700, the total power consumption of the priority A having the lowest priority is 8 million kW, and simply reducing the power of the priority A exceeds the upper limit of power consumption. It is necessary to reduce the remaining 2 million kW of power consumption from the power consumption of priority B having the next lowest priority. According to Table 700, the total power consumption of priority B is 25 million kW, which is 2 million kW / 25 million kW, and power consumption of 8% of priority B power consumption (16, 48, and 136 kW, respectively). It will be sufficient if it is reduced. Therefore, it is possible to reduce the power consumption of 2 million kW by reducing the power consumption of the priority B in each of the lower devices A, B, and N by 8%. As a result, the power consumption 713 to be reduced from the power consumption of the priorities A, B, and C is obtained for each subordinate apparatus, and the upper limit of the power consumption notified to the subordinate apparatuses 220 to 222 is calculated therefrom. The power distribution control unit 100 notifies the lower devices 220 to 222 of the upper limit 714 of power consumption obtained for each lower device. Receiving the notification, the lower devices 220 to 222 can repeat the same processing to calculate the power consumption when the power is reduced from the power consumption having a low priority as the entire system. In addition to this, power consumption based on priority may be reduced by an appropriate method.

５．機器制御装置
図３を参照し、本実施例における機器制御装置１０１を説明する。
機器制御装置１０１は上位の電力制御装置１００と、下位の実際の電力を消費する複数台の機器３２０〜３２２の間で、消費電力の収集、抑制電力の伝達、および機器の制御を行う。機器制御装置１０１は下位の機器３２０〜３２２ごとに周期的に通知される消費電力を収集し、その総消費電力を上位の電力制御装置１００へ通知する。その際、機器ごとに設定された優先度ごとに優先度別消費電力を計算し、総消費電力と合わせて上位装置に通知する。上述と同様に総消費電力は通知を省略してもよい。また、上位電力制御装置１００から消費電力の上限を通知された場合は、現在の消費電力から削減すべき電力を計算し、下位の機器を制御することにより消費電力を制御する。
図３に示す機器制御装置１０１は、電力制御機能部２００と機器制御機能部３００を有する。機器制御機能部３００は、下位の各機器３２０〜３２２を制御する機器制御部３０１と配下機器３２０〜３２２の情報を記録する機器データベース３０２を有する。機器データベース３０２の例を図８の表８００に示す。図８の表８００では各機器３２０〜３２２を識別するための機器名（又は機器識別子）８０１、制御方法８０２、設置場所８０３及び優先度８０４の項目を持ち、これらの情報を機器ごとに管理する。これらの情報はなんらかのユーザインタフェース（Ｉ／Ｆ）から設定することも可能である。また、機器制御部３０１と各機器３２０〜３２２の間で直接情報をやり取りし、取得する方法としてもよい。機器ごとの消費電力を計算するための機器名８０１および優先度８０４の項目以外の項目は機器の制御方法に従って適宜の項目を管理しても良い。
図９にユーザＩ／ＦとしてＷＥＢ−ＵＩから機器情報を設定する場合の設定画面例を示す。図９に示す機器情報設定画面９００は、機器制御装置１０１で管理する機器名を表示する領域９０１を持つ。また、機器情報設定画面９００は、例えば、ユーザにより各機器の詳細情報を設定するため、機器の設置場所を設定するテキストボックス９０２と、優先度を設定するプルダウンメニュー９０３、機器の制御方法を設定するプルダウンメニュー９０４からなる。このようなＩ／Ｆを機器制御装置に持たせることで、ユーザ、あるいは機器制御装置の設置作業者は宅内の機器情報を容易に設定することが可能である。また、消費電力の上限を通知された際の電力削減方法および削減可能電力を表示する、電力削減情報画面９１０のようなＷＥＢ画面を表示させることも可能である。図９の電力削減情報画面では機器名、消費電力を削減する際の制御方法および削減する消費電力を表示する。また、現在の消費電力を表示している。 5. Device Control Device With reference to FIG. 3, the device control device 101 in this embodiment will be described.
The device control apparatus 101 collects power consumption, transmits suppressed power, and controls devices between the upper power control apparatus 100 and a plurality of devices 320 to 322 that consume lower actual power. The device control apparatus 101 collects the power consumption periodically notified for each of the lower devices 320 to 322 and notifies the upper power control device 100 of the total power consumption. At that time, power consumption for each priority is calculated for each priority set for each device, and is notified to the host device together with the total power consumption. The notification of the total power consumption may be omitted as described above. Further, when the upper limit of power consumption is notified from the upper power control apparatus 100, the power to be reduced is calculated from the current power consumption, and the power consumption is controlled by controlling the lower devices.
The device control apparatus 101 illustrated in FIG. 3 includes a power control function unit 200 and a device control function unit 300. The device control function unit 300 includes a device control unit 301 that controls each of the lower devices 320 to 322 and a device database 302 that records information on the subordinate devices 320 to 322. An example of the device database 302 is shown in a table 800 of FIG. 8 includes items of a device name (or device identifier) 801, a control method 802, an installation location 803, and a priority 804 for identifying each device 320 to 322, and manages these pieces of information for each device. . These pieces of information can also be set from some user interface (I / F). Alternatively, a method may be used in which information is directly exchanged between the device control unit 301 and each of the devices 320 to 322 and acquired. Items other than the items of the device name 801 and the priority 804 for calculating the power consumption for each device may be managed according to the device control method.
FIG. 9 shows an example of a setting screen when device information is set from the WEB-UI as the user I / F. The device information setting screen 900 shown in FIG. 9 has an area 901 for displaying device names managed by the device control apparatus 101. In addition, the device information setting screen 900 sets, for example, a text box 902 for setting a device installation location, a pull-down menu 903 for setting a priority, and a device control method in order to set detailed information of each device by the user. A pull-down menu 904 is displayed. By providing the device control apparatus with such an I / F, a user or an operator who installs the device control apparatus can easily set home device information. It is also possible to display a WEB screen such as the power reduction information screen 910 that displays the power reduction method and the reducible power when the upper limit of power consumption is notified. In the power reduction information screen of FIG. 9, the device name, the control method for reducing power consumption, and the power consumption to be reduced are displayed. In addition, the current power consumption is displayed.

機器制御機能部３００では下位の機器３２０〜３２２から通知される消費電力、その他の情報を収集し、機器データベース３０２より取得した機器に対応する優先度８０４の項目と収集した情報とを関連づけ、機器ごとの消費電力及び優先度を電力制御機能部２００へ通知する。機器制御装置１０１の電力制御機能部２００では通知された消費電力および優先度別消費電力を機器ごとに管理し、電力記憶部２０１に記録する。図８の表８１０に、電力記憶部２０１の構成例を示す。また、機器制御装置１０１は、収集した消費電力および優先度別消費電力の結果８１６を上位の電力制御装置１００へ通知する。
機器制御部３０１の処理シーケンスを図６に示す。機器制御部３０１は下位の各機器から消費電力の通知を受けた場合（Ｓ６０１）、機器データベース３０２より該当する機器のエントリの優先度を取得し（Ｓ６０２）、取得した消費電力をその優先度別消費電力として電力収集機能部２０２へ通知する（Ｓ６０３）。一方、機器制御部３０１は、電力分散制御部２０３から消費電力の上限を通知された場合（Ｓ６０１）、該当する機器エントリの制御方法を機器データベース３０２を参照して特定し機器を制御する（Ｓ６０５）。一例として、機器の電源をＯＦＦにするなどして、機器で消費される電力を制御する。
図８の表８１０に機器制御装置１０１が収集する消費電力の例を示す。表８１０では配下の機器３２０〜３２２から通知された消費電力と機器データベース３０２に設定された優先度８０４を関連付け、それぞれの優先度別消費電力を算出する。例えば、機器Ａ３２０から通知された消費電力は３００Ｗであり、機器データベース３０２から機器Ａ３２０の優先度８０４はＡであるため、機器Ａ３２０の優先度別消費電力は優先度Ａの３００Ｗとしている。同様に他の機器の消費電力と優先度別消費電力を求め、消費電力と、優先度別消費電力のそれぞれの合計８１６を上位の電力制御装置１００に通知する。
次に本実施例における機器制御装置１０１の抑制消費電力の伝達方法について説明する。本実施例の一態様によれば、上位の電力制御装置１００から消費電力の上限を通知された場合、電力制御機能部２００により、上述の電力制御装置１００と同様に、機器ごとの消費電力を優先度別に計算し、機器制御機能部３００へ通知する。機器制御機能部３００は優先度の低い機器から消費電力を削減することで、消費電力を抑えることができる。
図３に示す機器制御装置１０１の一態様によれば、電力制御機能部２００と機器制御機能部３００は一つの装置内に実現されているが、これらの機能は別々の装置として実現しても良い。また、図８の表８００に示す機器の制御方法８０２は電源ＯＦＦ／ＯＮのみである。そのため、上位装置から通知される消費電力の上限により、消費電力を削減する場合、本実施例では機器の電源をＯＦＦすることで消費電力を削減する方法を例として示している。しかしながら、実際の消費電力の削減方法はこれ以外の方法としてもよい。例えば、エアコンの設定温度を調節するなどして消費電力を調整できる。また、太陽電池や蓄電池などにより電力の供給が可能なシステムではそれらの電力を使用するなどの方法も考えられる。本実施例では実際の機器の具体的な制御方法および電力の削減方法については限定しない。
本実施例においては、機器から収集される消費電力は例えば瞬時電力とすることができる。なお、所定時間の累積値を用いても良い。消費電力の上限が設定された場合は収集した消費電力（過去の電力消費の実績）に基づいて優先度毎に消費電力の上限を設定する（これから消費する電力を制限する）。各機器の使用状況や優先度に基づき消費電力を削減でき、リアルタイム性も追求できる。 The device control function unit 300 collects power consumption and other information notified from the lower devices 320 to 322, associates the items of priority 804 corresponding to the devices acquired from the device database 302 with the collected information, and Each power consumption and priority is notified to the power control function unit 200. The power control function unit 200 of the device control apparatus 101 manages the notified power consumption and power consumption by priority for each device and records them in the power storage unit 201. A table 810 in FIG. 8 shows a configuration example of the power storage unit 201. In addition, the device control apparatus 101 notifies the higher-level power control apparatus 100 of the collected power consumption and the result 816 of power consumption by priority.
A processing sequence of the device control unit 301 is shown in FIG. When receiving the power consumption notification from each lower device (S601), the device control unit 301 acquires the priority of the corresponding device entry from the device database 302 (S602), and the acquired power consumption is classified according to the priority. The power collection function unit 202 is notified of the power consumption (S603). On the other hand, when notified of the upper limit of power consumption from the power distribution control unit 203 (S601), the device control unit 301 specifies the control method of the corresponding device entry with reference to the device database 302 and controls the device (S605). ). As an example, the power consumed by the device is controlled by turning off the device.
Table 810 in FIG. 8 shows examples of power consumption collected by the device control apparatus 101. In Table 810, the power consumption notified from the subordinate devices 320 to 322 is associated with the priority 804 set in the device database 302, and the power consumption for each priority is calculated. For example, the power consumption notified from the device A320 is 300 W, and the priority 804 of the device A320 from the device database 302 is A, so the power consumption by priority of the device A320 is set to 300 W of the priority A. Similarly, the power consumption of other devices and the power consumption by priority are obtained, and the upper power control apparatus 100 is notified of the total 816 of the power consumption and the power consumption by priority.
Next, a method for transmitting the suppressed power consumption of the device control apparatus 101 in this embodiment will be described. According to one aspect of the present embodiment, when the upper limit of power consumption is notified from the upper power control apparatus 100, the power control function unit 200 calculates the power consumption for each device in the same manner as the power control apparatus 100 described above. Calculation is performed for each priority, and the device control function unit 300 is notified. The device control function unit 300 can reduce power consumption by reducing power consumption from devices with low priority.
According to one aspect of the device control device 101 shown in FIG. 3, the power control function unit 200 and the device control function unit 300 are realized in one device, but these functions may be realized as separate devices. good. Further, the device control method 802 shown in the table 800 of FIG. 8 is only power OFF / ON. For this reason, in the case where the power consumption is reduced by the upper limit of the power consumption notified from the host device, in this embodiment, a method of reducing the power consumption by turning off the power of the device is shown as an example. However, the actual power consumption reduction method may be other methods. For example, the power consumption can be adjusted by adjusting the set temperature of the air conditioner. Further, in a system in which power can be supplied by a solar battery, a storage battery, or the like, a method of using such power can be considered. In the present embodiment, a specific method for controlling an actual device and a method for reducing power are not limited.
In the present embodiment, the power consumption collected from the device can be, for example, instantaneous power. An accumulated value for a predetermined time may be used. When the upper limit of power consumption is set, the upper limit of power consumption is set for each priority based on the collected power consumption (past power consumption record) (the power consumed from now on is limited). Power consumption can be reduced based on the usage status and priority of each device, and real-time performance can be pursued.

（実施例２）
本実施例では、上記の実施例１に加えて、社会システム上優先度の高い施設、例えば医療機関などの医療機器に対して高優先度を設定する場合の実施例について説明する。
図１０に示す本実施例のシステム構成は、例えば各家庭の消費電力を収集、および抑制電力を伝達する地域電力制御装置１０２１と、医療機関などの電力を収集、および抑制電力の伝達する特定電力制御装置１０２０を含む。また、特定電力制御装置１０２０と地域電力制御装置の上位に、広域電力制御装置１０１０と、全域電力制御装置１０００とを有する。地域電力制御装置１０２１の下位には、宅内機器制御装置１０３１などの機器制御装置が接続され、特定電力制御装置１０２０の下位には、医療機器を制御する医療機器制御装置１０３０が接続される。全域電力制御装置１０００は、実施例１の最上位の電力制御装置１００に相当し、広域電力制御装置１０１０、地域電力制御装置１０２１は、その下位の複数階層の電力制御装置１００に相当する。宅内機器制御装置１０３１及び医療機器制御装置１０３０は、実施例１の機器制御装置１０１に相当する。このようなシステム構成において、例えば、一般の機器１０４１で消費する電力に対して設定する優先度をＡからＣとし、医療機関などで使用する電力にはＤからＦの高優先度を設定することで、医療機関で消費される電力は他の電力に比べ削減されにくく管理することが可能である。
図１１に特定電力制御装置１０２０の収集する消費電力と上位装置へ通知する消費電力の例を示す。ここで、特定電力制御装置１０２０は、電力収集制御部２０２にて、収集した消費電力をＤ〜Ｆの高優先度の電力に補正する設定がなされているものとする。図１１では特定電力制御装置１０２０は下位の医療機器制御装置１０３０から消費電力１１０１〜１１０２を通知される。ここでは、医療機器の優先度はＡ〜Ｃに設定されているものとする。特定電力制御装置１０３０の電力収集制御部２０２ではこの情報を電力記憶部２０１に記憶する。また、上位装置に消費電力を通知する際に、特定電力制御装置１０２０で優先度別消費電力として通知されたＡ〜Ｃの消費電力をＤ〜Ｆとして高い優先度に補正し（図４のＳ４０４）、上位装置に通知する。上位装置としての広域電力制御装置１０１０で収集した消費電力の例を図１１の表１１１０に示す。これにより、上位装置で消費電力の上限を通知する際は、優先度Ａ〜Ｃの電力が先に削減され、特定消費電力制御装置１０２０配下の電力を優先的に残すことが可能となる。ここで、図１１の１１１０の例では特定電力制御装置１０２０で収集した優先度Ａ〜Ｃの消費電力に対して、全ての優先度をＤ〜Ｆに上げているが、医療機器制御装置１０３０で管理する電力の中でも、優先度Ｃの電力のみ優先度を上げるなどの処理を行ってもよい。なお、上述の説明では医療機関を例に説明したが、これに限らず適宜の施設でもよい。また、医療機関等の施設内でも、特定電力制御装置１０２０の配下に接続される機器（例えば医療機器）と、地域電力制御装置１０２１の配下に接続される機器（例えば自動販売機など医療と関連が少ない機器）があってもよい。
また、さらに上記の実施例の別の実施例として、広域電力制御装置１０１１として工場地帯などの電力と住宅地域などの電力を分けて制御し、工場地帯の優先度を変更するなどの方法も考えられる。
このように、本実施例における電力制御方法によって、システムとして最適な優先度の設定と管理を容易に行うことができ、柔軟なシステム設計が可能となる。 (Example 2)
In this embodiment, in addition to the first embodiment, an embodiment in which a high priority is set for a medical device such as a medical facility such as a medical institution having a high priority in the social system will be described.
The system configuration of the present embodiment illustrated in FIG. 10 includes, for example, a local power control apparatus 1021 that collects power consumption of each home and transmits suppression power, and a specific power that collects power of a medical institution and transmits suppression power. A control device 1020 is included. In addition, the wide area power control apparatus 1010 and the whole area power control apparatus 1000 are provided above the specific power control apparatus 1020 and the regional power control apparatus. A device control device such as a home device control device 1031 is connected to a lower level of the regional power control device 1021, and a medical device control device 1030 for controlling the medical device is connected to a lower level of the specific power control device 1020. The global power control apparatus 1000 corresponds to the highest power control apparatus 100 of the first embodiment, and the wide area power control apparatus 1010 and the regional power control apparatus 1021 correspond to the power control apparatuses 100 of a plurality of lower layers. The in-home device control device 1031 and the medical device control device 1030 correspond to the device control device 101 of the first embodiment. In such a system configuration, for example, the priority set for the power consumed by the general device 1041 is set from A to C, and the high priority set from D to F is set for the power used in a medical institution or the like. Thus, the power consumed in medical institutions can be managed less easily than other types of power.
FIG. 11 shows an example of power consumption collected by the specific power control apparatus 1020 and power consumption notified to the host apparatus. Here, in the specific power control apparatus 1020, it is assumed that the power collection control unit 202 is configured to correct the collected power consumption to high priority powers D to F. In FIG. 11, the specific power control apparatus 1020 is notified of power consumption 1101 to 1102 from the lower-level medical device control apparatus 1030. Here, it is assumed that the priority of the medical device is set to A to C. The power collection control unit 202 of the specific power control apparatus 1030 stores this information in the power storage unit 201. Further, when notifying the power consumption to the host device, the power consumption of A to C notified as the power consumption by priority in the specific power control apparatus 1020 is corrected to a high priority as D to F (S404 in FIG. 4). ) And notify the host device. An example of power consumption collected by the wide area power control apparatus 1010 as the host apparatus is shown in a table 1110 of FIG. As a result, when the upper device notifies the upper limit of power consumption, the powers of the priorities A to C are reduced first, and the power under the specific power consumption control device 1020 can be left preferentially. Here, in the example of 1110 in FIG. 11, all the priorities are increased to D to F with respect to the power consumption of the priorities A to C collected by the specific power control apparatus 1020, but in the medical device control apparatus 1030.
