Description

Technical Field

[0001] The present invention belongs to the technical field of power spot markets, and particularly relates to a method and system for parallel operation of a primary and standby heterogeneous power spot technical support system. Background Art

[0002] With the advancement of China's power market reform, more and more provinces have started to build power spot markets. After the completion of the power spot market, the planned power of market members in the power grid and the settlement basis of market entities both depend on the clearing results of the power spot technical support system (referred to as the spot system). If the market is interrupted or the clearing results are unreasonable, it will not only affect the safe and stable operation of the power grid, but also affect the economic interests of market entities and then cause market fluctuations. Therefore, both the safe operation of the power grid and the stable operation of the power market have extremely high requirements for the clearing results of the power spot technical support system.

[0003] Currently, in power spot pilot provinces, a primary power spot technical support system is established in the primary power dispatching center of the provincial power grid. To consider disaster tolerance and standby, some provinces have set up a standby power spot technical support system in the standby power dispatching center. Usually, the two sets of power spot technical support systems are homogeneous systems, that is: provided by the same supplier and using the same technical route. Under normal circumstances, only the primary power spot system performs a complete clearing calculation and executes the clearing results, while the standby power spot system is in a standby state, does not perform a clearing calculation, and the results are not executed.

[0004] The clearing calculation of the power spot technical support system involves a large amount of boundary data and complex clearing algorithms. Currently, the correctness of the clearing results mainly relies on manual testing or third-party evaluation systems for post-event analysis. Although these means can perform some rationality analysis on the clearing results, there is a lack of an intuitive comparison system for comprehensive comparison and verification as a whole.

[0005] Therefore, it is necessary to adopt corresponding technical means to compare and verify the clearing results of the spot system. A relatively reasonable way is to set up a heterogeneous standby power spot technical support system different from the primary power spot technical support system in the standby power dispatching center, that is: provided by different suppliers and using different technical routes. By running the two sets of power spot systems in parallel, controlling the use of the same data source and market model, performing clearing calculations simultaneously, and comparing and verifying the clearing results of the two sets of spot systems in real time, so as to analyze the difference items of the clearing results of the two sets of spot systems, find the reasons, and ultimately improve the correctness of the clearing results. The purpose of using heterogeneous power spot systems for parallel operation comparison and verification is to avoid the family defect problems of homogeneous systems.

[0006] In addition, the continuous operation ability of the spot system depends on the data of each business system. If the data of a certain business is interrupted or abnormal, it will affect the normal operation of the spot system. By switching the data source, a normal data source can be selected for clearing calculation, which can improve the continuous operation ability of the spot system. Summary of the Invention

[0007] The object of the present invention is to provide a method and system for parallel operation of a primary and standby heterogeneous power spot technical support system, which can improve the correctness of the clearing result through comprehensive comparison and verification of the clearing results of the dual-set power spot technical support system.

[0067] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and should not be used to limit the protection scope of the present invention.

[0068] As shown in Figure 1As shown in the figure, the present invention provides a parallel operation system for a primary and standby heterogeneous power spot technical support system, which includes a data source management module, a master-slave synchronization module, a parallel operation module, a clearing result comparison module, and a master-slave system switching module. Among them, the data source management module includes a primary dispatching data source management module and a standby dispatching data source management module. The data source management module obtains the required external data of the spot system from the primary dispatching business system, the standby dispatching business system, and the trading center system, and pushes the selected data source data to the spot system to execute the core business of the spot system. At the same time, the master-slave synchronization module synchronizes the data of the spot master system to the spot slave system, and the master-slave system switching module is also used to switch the states of the current spot master system and the slave system; the parallel operation module is used to realize the parallel clearing calculation of the spot master system and the spot slave system; the clearing result comparison module obtains the clearing result data from both sides of the spot system for comparison; only the spot master system sends the clearing result data to the execution systems such as AGC and the trading system.

[0069] As Figure 2 shown in the figure, the present invention provides a method for parallel operation of a primary and standby heterogeneous power spot technical support system, which specifically includes the operations of five modules:

[0070] (1) Establish a data source management module in the primary and standby power spot technical support system for managing the data files required by the spot system. The implementation process is as Figure 3 shown in the figure, and specifically includes the following steps:

[0071] S1: Establish a data type control parameter table (such as: dataTypeCtrlPara) in the database of the primary and standby power spot technical support system to describe the control parameters of the data required by the spot system. The control parameters include: data encoding, data name, data source, primary dispatching source file directory, standby dispatching source file directory, and final data usage directory. For example: for the short-term system load forecasting data required by the spot system, its parameter settings are:

[0072] Data encoding: DQXTFHYC;

[0073] Data name: Short-term system load forecasting;

[0074] Data source: Can be set to "primary dispatching source" or "standby dispatching source", here it is set to "primary dispatching source";

[0075] Primary dispatching source file directory: / users / ems / xhsc_data / DQXTFHYC / ZDY;

[0076] Standby dispatching source file directory: / users / ems / xhsc_data / DQXTFHYC / BDY;

[0077] Final data usage directory: / users / ems / xhsc_data_input / DQXTFHYC;

[0078] The spot market system requires many types of data. In addition to short-term system load forecasting data, it also includes ultra-short-term system load forecasting, short-term bus load forecasting, ultra-short-term bus load forecasting, maintenance plans, and other data. Each type of data sets its control parameters according to the above examples.

[0079] S2: The master and standby dispatching data source management modules obtain the corresponding data files from each business system to the directory specified by dataTypeCtrlPara in S1. For example, taking the standby dispatching data source management module obtaining short-term system load forecasting data as an example: The short-term system load forecasting data belongs to the load forecasting system. The standby dispatching data source management module obtains the short-term system load forecasting file from the master dispatching load forecasting system and places it in the master dispatching source file directory, such as: / users / ems / xhsc_data / DQXTFHYC / ZDY, and obtains the short-term system load forecasting file from the standby dispatching load forecasting system and places it in the standby dispatching source file directory, such as: / users / ems / xhsc_data / DQXTFHYC / BDY;

[0080] S3: The data source management module places the files in the corresponding data source directory into the final data usage directory according to the data sources set in dataTypeCtrlPara. For example: If the data source set for short-term system load forecasting is "master dispatching source", when a new file is detected in the / users / ems / xhsc_data / DQXTFHYC / ZDY directory, then this file is placed in the final data usage directory: / users / ems / xhsc_data_input / DQXTFHYC.

[0081] S4: The files in the final data usage directory are the data finally used by the power spot market technical support system. The above steps are common to the master and standby dispatching data source management modules. Therefore, the master and standby dispatching data source management modules can control the selection of the same data source for each type of data. In this way, the master and standby dispatching power spot market technical support systems can use the same data source for clearing, which is convenient for result comparison and verification; in addition, when the data of a certain data source is abnormal or fails, the normal data source can also be selected through control, which also improves the reliability of the data and ensures the uninterrupted operation of the spot market system.

[0082] (2) Establish a master-slave synchronization module for the spot market system in the master and standby dispatching power spot market technical support system, including the following steps:

[0083] The model parameter maintenance and input data modification of the spot system are only carried out in the main spot system. To ensure the consistency of the market model, control parameters, and manually modified data between the main and slave spot systems, the main system needs to synchronize this data to the slave system. In this way, the spot slave system can be consistent with the main system without any operations. As a result, the actual executed system is the main system, and the system that only runs without executing the results is the slave system. The main and slave systems can be switched, so the main dispatching power spot technical support system can be either the main system or the slave system.

[0084] The data synchronization of the primary and standby dispatching heterogeneous power spot technical support systems is achieved through the master-slave synchronization module. Since the modeling methods and data storage methods adopted by heterogeneous systems are different, conversions are required during master-slave synchronization. The implementation process is as Figure 4 shown, and the steps are as follows:

[0085] S1: Set synchronization intermediate tables in the databases of the main dispatching and standby dispatching power spot technical support systems. The data stored in these tables is the data that needs to be synchronized. The structure of the intermediate tables contains the complete information of the synchronized data. For example, if the market unit model needs to be synchronized between the master and slave systems, a market unit intermediate table (such as: MktGenUnitZJB) needs to be established. The intermediate table includes the codes used for matching by the two sides of the spot system. Both sides of the spot system can map their internal models or data through this code, including parameters such as unit code, unit name, affiliated market member, unit rated capacity, minimum technical output of the unit, unit ramp rate, and whether to participate in the market.

[0086] S2: The main spot system updates the market model, control parameters, and manually modified data with changes in the internal table to the intermediate table on the main dispatching side. A mapping relationship is established between the main system's internal table and the intermediate table for the update.

[0087] S3: When the database synchronization tool (the database synchronization tool is an existing technology and a general tool) detects changes (insertion, deletion, or modification) in the intermediate table of the main system, it triggers the data synchronization to the intermediate table of the slave system.

[0088] S4: After the spot slave system detects changes in the intermediate table data of the slave system, it updates the data in the intermediate table of the slave system to the internal table of the slave system. A mapping relationship is established between the internal table of the slave system and the intermediate table for the update.

[0089] Through the above steps, the data synchronization from the main spot system to the slave spot system is completed. In this way, only the data is modified in the main system, and the slave system will also be consistent with the main system without the need to modify it again in the slave system.

[0090] (3) The primary and standby dispatching spot systems operate in parallel, as Figure 5 shown, including the following steps:

[0091] S1: In step 1, the master-slave dispatching data source management module sends the selected data source data into the spot system data access directory;

[0092] S2: The master-slave dispatching spot systems respectively import the data source data selected by the data source management module on their own sides;

[0093] S3: The master-slave synchronization module set in the master-slave dispatching spot systems synchronizes the changed data of the master system to the slave system to form the master-dispatching and slave-dispatching spot system databases;

[0094] S4: The master-slave dispatching spot systems respectively perform clearing calculations for each market according to the market process;

[0095] S5: The spot master system sends the clearing results to execution systems such as AGC and the trading center.

[0096] (4) Establish a clearing result comparison module for the master-slave dispatching spot systems in the master-slave dispatching power spot technical support system, as shown in Figure 6 , including the following steps:

[0097] S1: According to the market clearing process, after the master-slave dispatching spot systems complete the clearing calculations, export the clearing results into a clearing result file in a specified format and send it to the opposite-side spot system through the network channel; the clearing result file includes the complete content of the clearing results, specifically including: clearing object code, clearing object name, clearing result values for each time period; among them, the clearing object code is used to map internal objects in the master-slave dispatching spot systems; the clearing object can be a unit, a bus, a load, etc.;

[0098] S2: The local spot system obtains the clearing result data of the local spot system from the local spot database, and then reads the clearing result data sent by the opposite-side spot system through the file;

[0099] S3: The local and opposite-side clearing result data form comparison objects according to the clearing object code, and compare the clearing result values for each time period in turn; for example: there are 100 units in the spot market, taking the unit clearing results in the day-ahead market as an example for comparison, the clearing results in the day-ahead market include the result values for 96 time periods; compare the 96 result values of these 100 units in turn;

[0100] S4: List the clearing result difference items according to the comparison results and analyze the reasons for the differences manually; continuously process and iterate to improve the correctness of the clearing results.

[0101] (5) Establish a master-slave switching module for the master-slave dispatching spot systems in the master-slave dispatching power spot technical support system, as shown in Figure 7 , including the following steps:

[0102] S1: Set a switching flag in both the primary and backup power spot technical support systems. The master-slave status flag of the primary system is true, and that of the slave system is false.

[0103] S2: During switching, initiated by the primary system, first switch the primary system to the slave system, i.e., set the master-slave status flag in the primary system to false; then switch the slave system to the primary system, i.e., set the master-slave status flag in the slave system to true.

[0104] S3: After switching according to the steps in S2, the master-slave status switching is completed. The original primary system becomes the slave system, and the original slave system becomes the primary system.

[0105] When the primary power spot system has an operation failure or the accuracy of the clearing result is not as good as that of the backup power spot system, the current primary power spot system is switched to the slave system, and the backup power spot system is switched to the primary system through the system switching method to ensure the uninterrupted operation of the power spot system with high reliability.

[0106] After switching, the two power spot systems still operate in parallel and clear independently. Only when the power spot system is the primary system can the clearing result be sent to execution systems such as AGC and the trading center for execution.

[0107] Through the above embodiments, a method and system for parallel operation of a primary and backup heterogeneous power spot technical support system provided by the present invention controls and selects the same external data data source through the primary and backup data source management module, keeps the market models of the primary and backup power spot technical support systems consistent through spot master-slave synchronization, performs parallel clearing of the primary and backup heterogeneous power spot technical support systems based on the same data source and market model, shields the family defects of homogeneous systems, comprehensively compares the clearing results of the two power spot technical support systems through the clearing result comparison module of the primary and backup power spot technical support systems, and improves the correctness of the clearing results of the power spot system. In addition, the data source management module flexibly selects the data source to improve the compatibility with single data source anomalies. Through the master-slave system switching, the system with excellent clearing results is flexibly selected as the primary system to improve the clearing result accuracy rate and continuous operation ability of the power spot technical support system.
