In addition, each Enterprises have their own corporate logos, and the power dispatching system can distribute power to each enterprise according to the corporate logos.

As shown in Figure 2, this embodiment provides a method for dispatching and distributing electric power in an enterprise, including the following steps:

S101: The virtual storage power station system receives the power consumption information reported by the power consumption equipment of one or more enterprises in real time;

The electricity consumption information includes: enterprise identification, electrical equipment identification, and the electricity consumption, working status parameters and time of the electrical equipment, and the working status parameters include the current, power and running status of the electrical equipment;

The electricity consumption equipment of the enterprise is equipped with intelligent relays, and the electricity consumption information reported by the electricity consumption equipment of the enterprise in real time is sent to the virtual storage power station system through the intelligent relays.

S102: The virtual storage power station system calculates the total electricity consumption of each enterprise within a preset period according to the electricity consumption information of each enterprise's electrical equipment, and reports it to the power dispatching system;

Among them, the virtual storage power station system will process and analyze the power consumption information reported by large-scale enterprise power consumption equipment from the dimensions of ownership of enterprises and power consumption, specifically:

The virtual storage power station system identifies the electrical equipment of the same enterprise according to the enterprise identification, and counts the total power consumption of all electrical equipment of the same enterprise within a preset period.

S103: The power dispatching system dispatches power plants to generate electricity according to the total electricity consumption of each enterprise within a preset period, and distributes corresponding electricity to each enterprise.

The power consumption equipment of large enterprises usually has a very large power. The virtual storage power station system can count the total electricity consumption of enterprises in various periods according to needs, such as 1 hour (can be used to dispatch power generation and distribute power to enterprises), 1 day (can be used for charging check), 1 month (can be used for charging checking), if you want to count a very short time interval (can be used to monitor the working status of equipment), such as the power consumption of enterprise equipment in 5 minutes, then you need to calculate the smart The relay sets the corresponding parameter reporting cycle to increase the frequency of smart relay reporting.

For example, the data reporting period of the smart relay of the electrical equipment can be preset to 5 minutes. After the virtual storage power station system receives the data reported by the electrical equipment every 5 minutes, it can perform various statistics in multiples of 5 minutes. Such as every 5 minutes stats, hourly stats, daily stats and monthly stats. Every 5-minute statistical data can be used for enterprises to monitor the working status of their electrical equipment and fault alarms, and hourly statistical data can be used for dispatching power generation of power plants and distribution of power to enterprises, such as power dispatching According to the total electricity consumption of enterprises counted by the virtual storage power station system every hour, the system dispatches the total power generation of power plants for the next hour, and distributes corresponding electricity to enterprises according to the electricity consumption of each enterprise.

The statistical results of the virtual storage power station system are used as the basis for the dispatch of power plants by the provincial power system and the distribution of electricity for each production enterprise. It is usually set as the total electricity in the cycle with a small amount of surplus (such as 0.1%)

For example, the power dispatching system can dispatch the power generation of the power plant for the next day according to the total daily power consumption of each enterprise according to the statistics, and distribute the next day's power to each enterprise according to the daily power consumption of each enterprise. However, due to the different production characteristics of each enterprise (working day and rest day), the daily electricity consumption within a week may vary greatly. Dispatch the power generation of the power plant on Monday, and distribute the corresponding electricity to each enterprise according to the total electricity consumption of each enterprise.

For another example, each enterprise has different production characteristics (day and night). If the power dispatching system wants to conduct more refined dispatch, it needs to dispatch the hourly power consumption of each enterprise based on the statistics of the total electricity consumption of each enterprise per hour. Power generation, according to the electricity consumption of each enterprise for each hour, distribute the electricity for the next hour to each enterprise.

The tidal effect of power supply means that the power consumption of a single enterprise may suddenly increase or decrease. Secondly, the power consumption peaks of power-consuming enterprises are not the same. Some have peak power consumption during the day, and some have peak power consumption at night. The working day is the peak, and some holidays are the peak instead. The statistical results of different periods of each enterprise reported by the virtual storage power station system provide the power dispatching system with a basis for dispatching the power generation of the power plant as a whole. The power dispatching system can keep abreast of the status of each enterprise. The power consumption situation, comprehensive analysis of the power consumption situation of all enterprises, facilitates corresponding adjustments to power dispatching from a global perspective, overcomes the problems caused by power tides, and avoids the situation that power plants generate too much waste and less power cannot meet demand as a whole occur.

As a preferred manner, the method also includes:

The virtual storage power station system counts the total power consumption, current change, power change and operating status of each electric device of each enterprise within a preset period, and saves them in the memory of the virtual storage power station system for enterprise scheduling Personnel monitoring and inquiries;

Enterprise dispatchers can log in to the system according to the login user name and password assigned to the enterprise by the virtual storage power station system, and inquire about the electricity consumption information of each electrical equipment of the enterprise, whether the equipment's electricity consumption is normal, etc. For example, if the current of a certain electrical equipment changes greatly suddenly, there may be problems such as failure of the electrical equipment, the enterprise dispatcher can send a shutdown control command to the electrical equipment through the virtual storage power station system, so that the electrical equipment Electrical equipment stops working.

As a preferred manner, the method also includes:

When the virtual storage power station system detects that the current or power of a certain enterprise’s electrical equipment changes suddenly at a certain moment, it sends an alarm message to the monitoring terminal of the enterprise, such as sending a short message or prompting the alarm message on its monitoring terminal , actively notify the dispatcher of the enterprise, so that the dispatcher of the enterprise can know the sudden change in time, and then send the corresponding control command.

As a preferred manner, the method further includes: the virtual storage power station system receiving a control command issued by the dispatcher of the enterprise, the control command carrying the enterprise identification, the identification of the electrical equipment of the enterprise and the control action;

The virtual storage power station system forwards the control instruction to the smart relay of the corresponding enterprise's electrical equipment according to the enterprise identification and the enterprise electrical equipment identification.

The intelligent relay executes the received control instructions, completes corresponding operations, and realizes remote and intelligent control of equipment power consumption.

For example, an enterprise can dynamically control the working status of a certain electrical equipment according to its own production needs. For example, the oil production equipment of some oil production plants only needs to work for 6 hours a day. The relay sends corresponding control commands.

The dispatchers of each enterprise can only monitor, inquire and control the electricity consumption equipment of the enterprise; the virtual storage power station system analyzes the electricity consumption information of the equipment, such as the current change of the equipment, the power change and the operation status at a certain moment (shutdown , sleep, full-load work), dynamically reflect the working status of the electrical equipment of each enterprise to the dispatcher of the enterprise, so that the dispatcher of the enterprise can keep abreast of the working status of all the electrical equipment of the enterprise, and dynamically control each The working status of electrical equipment; the dispatcher of the enterprise can send control instructions to the electrical equipment of the enterprise through the virtual storage power station system, and realize the intelligence of the electrical equipment of the enterprise through the communication interface between the virtual storage power station system and the electrical equipment of the enterprise.
