Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The application provides an inter-provincial power transaction settlement method which can realize automatic settlement of power transactions.
The scheme can be realized based on the electric power transaction system. Power transactions can be divided into two types, one being medium-to-long term transactions and the other being real-time transactions in the past. Wherein the medium-to-long term transaction may be settled on one or more months.
Next, as described in connection with fig. 1, an inter-provincial power transaction settlement method for medium-to-long term transactions will be described, and the method may include the following steps:
and step S100, acquiring power settlement data of the medium-and-long-term transaction.
In this embodiment, for the power settlement of the medium-long term transaction, first, the power settlement related data is acquired, where the data may include a contract corresponding to each medium-long term transaction, scheduling plan data generated based on each transaction plan data, TMR data, and headquarter settlement amount data, which are decomposed together to obtain corresponding transaction plan data.
The contract can include information of both transaction sides, transaction time period, transaction amount, transaction price, transaction direct current type and the like.
Transaction plan data corresponding to the contract can be obtained by decomposing the contract. The scheduling department may generate corresponding scheduling plan data based on the transaction plan data.
The TMR data is statistical data of daily power direct current transaction electric quantity of the power grid electric quantity metering system TMR system. Which counts the actual power settlement amount of each province.
The headquarter settlement amount data is the actual settlement amount provided by the national power grid to each subsection.
And step S110, based on the transaction direct current type and the transaction parties, establishing a corresponding relation among transaction plan data, dispatch plan data and headquarter settlement amount data.
Specifically, since each department in the electric power system defines different contract names and has no unified identification code, the prior art needs to manually consider and identify the corresponding relation between each contract.
In this embodiment, the transaction direct current type and the transaction both sides are fixed based on the contract, the transaction plan data and the dispatch plan data, so that the corresponding relationship among the transaction plan data, the dispatch plan data and the headquarter settlement amount data can be established based on the transaction direct current type and the transaction both sides. By establishing a corresponding relation, the contract, the scheduling plan data and the headquarter settlement amount data of each medium-long term transaction can be determined, and a data basis is provided for the subsequent electric power settlement of the medium-long term transaction.
And step S120, generating deviation electric quantity by using the scheduling plan data and the headquarter settlement amount data corresponding to the contract for each medium-long term transaction.
The schedule plan data is schedule plan data, and is not an actual execution power. The actual execution power is the total settlement amount data. For a medium-long term transaction, the contract, the scheduling plan data and the headquarter settlement amount data of the medium-long term transaction are determined through the previous step, and when the three data are summarized, the planned electric quantity in the scheduling plan data is found to be unequal to the actual execution electric quantity in the headquarter settlement amount data, so that deviation processing is needed.
In the deviation processing, the actual execution power in the total settlement amount data may be subtracted from the planned power in the schedule plan data, and the result may be used as the deviation power.
And step S130, distributing the deviation electric quantity to daily scheduling plan quantities in the scheduling plan data to obtain daily actual execution quantities of each medium-long term transaction.
Specifically, the deviation electricity obtained in the previous step needs to be distributed to the daily scheduling plan amount in the scheduling plan data, so as to score the daily actual execution amount of each distributed medium-long term transaction.
Alternatively, the foregoing process of allocating the offset power may have two allocation manners:
and firstly, taking the daily scheduling plan amount in the scheduling plan data as an allocation weight, and allocating the deviation electric quantity to the daily scheduling plan amount according to the allocation weight to obtain the daily actual execution amount of each medium-long term transaction.
And secondly, distributing the deviation electricity quantity to daily scheduling plan quantity according to an average distribution mode to obtain daily actual execution quantity of each medium-long term transaction.
And step 140, calculating and obtaining the electric charge of each medium-long term transaction based on the transaction price and the transaction amount specified in the contract of each medium-long term transaction.
Specifically, the trade price and the trade amount are specified in each contract for the medium-long term trade, so that the electric charge for each medium-long term trade can be calculated based on the trade price and the trade amount.
According to the inter-provincial power transaction settlement method, power settlement data of medium-long term transactions are obtained, wherein the power settlement data comprises contracts corresponding to each medium-long term transaction, corresponding transaction plan data are obtained through combination and decomposition, and scheduling plan data, TMR data and headquarter settlement amount data are generated based on each transaction plan data; based on the transaction direct current type and the transaction parties, establishing a corresponding relation among transaction plan data, dispatch plan data and headquarter settlement amount data; for each medium-long term transaction, generating deviation electric quantity by using scheduling plan data and total settlement data corresponding to the contract; distributing the deviation electric quantity to daily scheduling plan quantities in the scheduling plan data to obtain daily actual execution quantities of each medium-long term transaction; and calculating the electric charge of each medium-long term transaction based on the transaction price and the transaction amount specified in each medium-long term transaction contract. Therefore, according to the scheme, the daily actual execution amount of the medium-and-long-term transaction and the settlement electricity fee can be determined, so that the automatic settlement of the medium-and-long-term transaction is realized, and compared with a manual accounting mode, the efficiency is greatly improved.
In another embodiment of the present application, the process of acquiring the power settlement data of the medium-long term transaction in the above step S100 will be described in detail.
1. Acquisition of contract data
Contracts can be entered according to specific contract documents and can be divided into trans-provincial transaction types and trans-regional transaction types. The electric power transaction system can acquire the recorded contract document of each medium-long term transaction, and further acquire the contract of each medium-long term transaction.
2. Acquisition of transaction planning data
The transaction plan data may be derived from a composite decomposition, and the decomposition rules may include:
each contract agrees with a trade time period and trade volume, so that trade volume can be divided into each month of each day in the trade time period according to the trade time period and trade volume to obtain trade plan data.
Wherein a daily power curve is obtained by halving the trade volume into each month of each day in the trade time period. For the power curve, the method and the device can provide a function of adjusting the power curve, namely, the power curve is adjusted according to a pre-recorded power curve adjustment rule, for example, the power curve is adjusted according to a day-to-day and hour-to-hour adjustment rule, and transaction plan data is obtained after adjustment.
3. Acquisition of scheduling plan data
The dispatch plan data is dispatch execution plan data generated by the dispatched OMS system from the transaction plan data. The power transaction system may pre-define a file transfer manner with the OMS system, such as a FTP file transfer manner. The scheduling plan data generated by the OMS system is directly transmitted to a server fixed directory of the power transaction system by using an FTP file transmission mode, the power transaction system sets time for analyzing the scheduling plan data, then content analysis is carried out on the scheduling plan data at the set time, the analyzed scheduling plan data is obtained, and the analyzed scheduling plan data is stored in a database.
4. Acquisition of TMR data
TMR data is a statistic of actual transaction electricity amount of each power direct current per day by a TMR system (grid electricity amount meter billing system). The power transaction system may pre-define a file transfer manner with the TMR system, such as a FTP file transfer manner. The daily direct current actual electric quantity information file generated by the TMR system is directly transmitted to a fixed directory of a server of the power transaction system by using an FTP file transmission mode, the power transaction system sets the time for analyzing the data, further performs content analysis on the daily direct current actual electric quantity information file at the set time, obtains analyzed TMR data, and stores the analyzed TMR data in a database.
5. Acquisition of headquarter settlement amount data
The monthly national grid will provide the actual settlement of the monthly cross-zone transactions on each division, which may be communicated in excel form. Thus, the electric power transaction system can acquire the headquarter settlement amount data.
In another embodiment of the present application, another alternative implementation of the inter-provincial power transaction settlement method is described, and compared to the solution illustrated in fig. 1, the following processing steps may be further added in the embodiment of the present application:
and respectively carrying out data statistics and graphical display on the contract, the transaction plan data, the dispatch plan data, the TMR data and the headquarter settlement amount data in the electric power settlement data.
The process of data statistics and graphical presentation of the different data is described separately.
1. Contract with a user
The contract information can count the transaction amount of the month of each province according to the month and the transaction amount of the month of each direct current according to the electricity selling party, the electricity purchasing party and the direct current. And counting a transaction curve according to the direct current, and checking whether the contractual power curve exceeds the highest upper limit of the direct current.
The transaction information can be intuitively displayed in a graphical mode according to the distribution of direct current on the map.
2. Transaction plan data
The transaction plan data can be displayed in an omnibearing manner according to statistical modes such as electric quantity balance prediction, transaction plan summarization, transaction plan detail, transaction plan curve and the like. For example, the transaction plan curve mode shows 24-point curve information of the month every day according to the monthly transaction amount of the contract and the transaction curve rule. The dc execution power at each time point can be counted.
3. Scheduling plan data
The dispatch plan data is corresponding to the contract, and the summarizing mode is similar to the contract mode, so that the transaction amount of direct current and the transaction amount of each province can be counted according to the direct current and the transaction parties.
4. TMR data
TMR data differs significantly from other data types that exist today. The method refines the direct current, and can summarize the specific net purchase quantity of each province according to the corresponding relation of the direct current.
For example, we need to know the purchase amount of Shaanxi on a certain day, and we need to summarize the amount of each direct current node in TMR data: tianbao, qinbao, meibao, letao, maibao I and Maibao II need to know the supply and output of Shanxi, and then need to be summarized: baodian, baozhen, baofei, taolele, qianlian, baominan, baomai and Baomai. The net purchase amount is then obtained from the purchase amount-supply amount.
5. Headquarter settlement data
Transaction data of each province can be counted according to the direct current type and the province and the month count.
In another embodiment of the present application, the process of establishing the correspondence between the transaction plan data, the dispatch plan data, and the headquarter settlement amount data based on the transaction direct current type and the transaction parties in step S110 is described.
In this embodiment, a correspondence relationship between transaction plan data and dispatch plan data, and a correspondence relationship between transaction plan data and headquarter settlement amount data may be established. Based on the above, the corresponding relationship between the scheduling plan data and the headquarter settlement amount data can be established through the middleware of the transaction plan data, that is, the corresponding relationship among the transaction plan data, the scheduling plan data and the headquarter settlement amount data is finally established, so that the corresponding transaction plan data, the scheduling plan data and the headquarter settlement amount data can be determined for each medium-term and long-term transaction data.
The process of establishing the correspondence between the transaction plan data and the dispatch plan data may include:
based on the transaction direct current type and the transaction two sides, establishing a corresponding relation between transaction plan data and scheduling plan data.
Specifically, the transaction plan data and the dispatch plan data both include transaction direct current type and transaction side, and the two pieces of information are not changed along with file naming, so that the transaction plan data and the dispatch plan data can be in corresponding relation based on the transaction direct current type and the transaction side.
Further, the establishment process of the correspondence between the transaction plan data and the headquarter settlement amount data may include:
based on the transaction direct current type and the transaction two parties, establishing a corresponding relation between transaction plan data and headquarter settlement amount data.
Specifically, the transaction plan data and the total settlement amount data both include a transaction direct current type and a transaction, and the two pieces of information are not changed along with file naming, so that the transaction plan data and the total settlement amount data can be in corresponding relation based on the transaction direct current type and the transaction both.
In another embodiment of the present application, a further alternative to the inter-provincial power transaction settlement method is presented.
Referring to fig. 2, the method for settling the inter-provincial power transaction in this embodiment may include:
step 200, acquiring power settlement data of medium-term and long-term transactions.
Step S210, based on the transaction direct current type and the transaction parties, establishing a corresponding relation among transaction plan data, dispatch plan data and headquarter settlement amount data.
Step S220, for each medium-long term transaction, generating deviation electric quantity by using scheduling plan data and headquarter settlement amount data corresponding to the contract.
And step S230, distributing the deviation electric quantity to daily scheduling plan quantities in the scheduling plan data to obtain daily actual execution quantities of each medium-long term transaction.
And step S240, calculating and obtaining the electric charge of each medium-long term transaction based on the transaction price and the transaction amount specified in the contract of each medium-long term transaction.
Specifically, the steps S200 to S240 correspond to the steps S100 to S140 in the foregoing embodiment one by one, and are described in detail with reference to the foregoing description, and are not repeated here.
Step S250, determining the net purchase deviation electric quantity of each province based on the actual settlement quantity of each province recorded by TMR data and the scheduling plan quantity of each province recorded by the scheduling plan data.
Specifically, the TMR data describes an actual settlement amount for each province, and since there is a deviation between the actual settlement amount and the scheduling amount described in the scheduling amount data, the scheduling amount can be subtracted from the actual settlement amount, and the result can be used as a net purchase deviation power.
It will be appreciated that the net purchase bias power in each province is positive and negative, but the net purchase bias power in each province is approximately zero, because the total amount of transactions between each province is fixed, one province purchases more, and other provinces purchase less. Therefore, the total of the net purchase bias power of each province approaches zero.
Step S260, determining unbalanced electric quantity of the connecting line between the provinces based on the net purchase deviation electric quantity of each province.
Specifically, to balance the bias of each province, the unbalanced power of the tie line between each province may be determined based on the net purchase bias power of each province.
Take northwest five provinces as an example for illustration:
defining the Shaanxi net purchase deviation electric quantity as 1848.089, the Gansu net purchase deviation electric quantity as-5278.206, the Qinghai net purchase deviation electric quantity as 2569.815, the Ningxia net purchase deviation electric quantity as 1009.662 and the Xinjiang net purchase deviation electric quantity as-150.854.
The unbalanced electric quantity of the interconnection lines between the provinces is respectively as follows:
shaanxi Gansu 1848.089, qinghai Gansu 2569.815, ningxia Gansu 860.302, ningxia Xinjiang 149.36.
On the basis of the power settlement of the medium-long term transaction described in the above embodiment, the embodiment of the application further describes an inter-provincial power transaction settlement process of the real-time transaction before the day.
As shown in connection with fig. 3, the inter-provincial power transaction settlement process of the real-time transaction before the day may include the steps of:
