[0002] With the advancement of the construction of new power systems, the proportion of new energy continues to increase, the installed capacity of conventional power sources such as coal-fired power has slowed down and the power generation space has been gradually compressed. The scale of new regulation resources on the load side has increased rapidly, but the ability of overall coordination and control is insufficient, and the flexible adjustment capacity cannot be effectively released. The operation of the power system faces problems such as insufficient balance support capacity, lack of adjustment flexibility, and difficulty in ensuring power supply in extreme situations.

[0003] As a conventional main power source, coal-fired power has the characteristics of storable primary energy and controllable secondary energy. It is an important means of peak load and frequency regulation of the power grid. Flexibility transformation is an important development direction of coal-fired power generating units. It can reduce the minimum output of the unit, increase the climbing rate / landing rate of the unit, and reduce the start and stop time of the unit, etc., effectively improving the flexibility adjustment capability. It is an important means to ensure power supply, promote the consumption of new energy, and enhance the balancing capacity of the power grid.

[0004] After the flexibility transformation, the operation characteristics of coal-fired power have changed significantly compared with before the transformation. During the operation, the relevant information of its flexible operation domain needs to be quickly and accurately connected to the power grid dispatching automation system, and the dispatching master station will make overall analysis and decision-making to maximize its flexible adjustment capabilities. At present, the safe and efficient access to the flexible operation domain data has not been perfected. Summary of the invention

If the data reported by the source end is abnormal, encapsulate the supplementary recruitment information into a message and send the supplementary recruitment message to the source end in the form of a request response;

[0008] Receive feedback data from the source end after verification and message encapsulation;

[0009] Parse the received message, verify the successfully parsed data, and store the successfully verified data.

[0016] Step S5: sending the message to the scheduling master station in a request response mode;

[0017] Step S6: After receiving the request, the scheduling master station records and parses the message. If an error occurs during the parsing process, the source station is notified of the interaction failure and the current round of interaction is terminated. If the parsing is successful, the next step is performed.

[0018] Step S7: Verify the parsed data according to the data verification rules of the scheduling master station for the successfully parsed message. If the verification fails, notify the source end of the verification exception information and terminate this round of interaction. If the verification succeeds, proceed to the next step.

[0019] Step S8: The successfully verified data is stored in the database of the scheduling master station, and the interaction status of the successful data interaction in this round is fed back to the source end;

[0020] Step S9: The source end receives the interaction status fed back by the scheduling master station, confirms that this round of data interaction is completed, and ends this round of interaction.

[0037] Figure 2 This is a flow chart of the data supplement mode at the power grid dispatching master station in the present invention. DETAILED DESCRIPTION

[0038] Example 1

[0039] The following is a detailed introduction to a method for accessing the coal-fired power flexible operation domain in this embodiment in conjunction with the accompanying drawings. The power grid dispatching master station can access the coal-fired power flexible operation domain data through sources such as the monitoring system at this level, the lower-level dispatching automation system, the plant-grid interaction platform, and the third-party comprehensive energy platform, showing the characteristics of multiple data sources, high interaction frequency, and complex interaction data structure.

[0040] In order to facilitate the monitoring and subsequent analysis and decision-making of the power grid dispatching master station, standardize the access to the data in the flexible operation domain of coal-fired power plants, propose a method for accessing the data in the flexible operation domain of coal-fired power plants, and design a standard interactive message for the data in the flexible operation domain in combination with the data model of the flexible operation domain of coal-fired power plants. The data covers the relevant contents of the flexible operation domain data model, is compatible with the basic power grid model of the dispatching automation system, and meets the requirements of cross-platform and cross-programming languages. The data access mode of the flexible operation domain at the power grid dispatching master station includes active reporting at the source end and data supplement at the power grid dispatching master station end. Both the source end and the power grid dispatching master station end interact in accordance with the standard specifications of the flexible operation domain data, and the interaction process is implemented based on the dispatching automation system platform service bus.

[0041] Step 1: First, build a data model for the flexible operation domain of coal-fired power. Refer to Table 1 to conduct flexible operation domain data modeling based on coal-fired power operation characteristics and regulation methods. The coal-fired power modeling object is based on the unit, and the modeling is conducted from the aspects of operation cost, operation constraint, operation boundary, etc.

[0042] Table 1 Description of data model for coal-fired power flexible operation domain

[0043]

[0044] The flexible operation cost of coal-fired power refers to the cost model parameters of the unit that are optimized and improved due to the flexibility transformation of coal-fired power. It may present different characteristics due to different stages and degrees of flexibility transformation. It mainly includes the unit startup cost and the unit operation cost, and is the key basis for the dispatching master station coal-fired power modeling. The startup of coal-fired power units is considered according to three startup methods: hot start, warm start, and cold start. The corresponding startup cost model parameters include hot start cost, warm start cost, cold start cost, hot to warm time, hot to cold time, etc. The unit operation cost refers to the cost curve corresponding to the unit at different output levels, which is usually U-shaped and modeled in sections. The main model parameters include the number of cost curve sections, the starting output of the section, the ending output of the section, and the section cost.

[0045] Coal-fired power flexible operation constraints refer to the unit operation constraint information improved due to the flexibility transformation of coal-fired power units. They are the key constraints for the optimization decision of coal-fired power in the dispatching master station. They mainly include the upper and lower limits of unit output power, unit ramp-up rate, unit minimum start-up operation time, unit minimum shutdown operation time, deep peak regulation minimum operation time, minimum start-up notification time, etc.

[0046] The flexible operation boundary of coal-fired power refers to the unit operation boundary data that changes due to the flexibility transformation of coal-fired power units. It is the key information for the optimization decision of coal-fired power in the dispatching master station. It mainly includes the unit fixed output plan, the unit must-start and must-stop plan, the unit maintenance plan, the unit adjustment standby plan, the maximum number of unit start and stop times, and the unit adjustable output range.

[0047] Step 2: Establish a flexible operation domain data access service at the power grid dispatching master station, monitor the data interaction requests of each data source, and support high-concurrency data processing; establish a flexible operation domain data reporting client at each data source or proxy source, and each data source submits a data reporting request in accordance with the interaction specifications and receives interaction status feedback messages from the server.

[0048] like Figure 1 As shown, under normal circumstances, the source end actively reports:

[0049] Step S1, the source end is manually or automatically triggered to start the data reporting process;

[0050] Step S2, the source end queries various types of flexible operation domain data to be reported according to the reported data collection configuration; the reported data collection configuration mainly includes the reporting period range, reporting object range, reporting data type, local data source and search parameters, etc.;

[0051] Step S3: The source end verifies the flexible operation domain data to be reported on-site according to the local verification rules. The local verification rules mainly include data integrity, parameter rationality, data association logic and other related rules. If the verification fails, an abnormal log is recorded, the sending process is terminated, and an alarm is sent to notify the operation and maintenance personnel to handle it in time. If the verification passes, proceed to the next step.

[0052] Step S4: if the data to be reported by the source end passes the verification, the data to be reported is encapsulated into a message according to the interaction specification according to the data sending configuration; the data sending configuration mainly includes the domain name, service name, and port number of the data sending destination, and supports the configuration of multiple sets of destination information;

[0053] Step S5, sending the message in a request response mode to the flexible operation domain data access service of the dispatching master station through the dispatching automation system platform service bus;

[0054] Step S6: After receiving the interaction request, the flexible operation domain data access service of the scheduling master station records and parses the original data interaction request message. If an error occurs during the parsing process, an abnormal log is recorded and an alarm is sent to notify the source end of the interaction failure and terminate the current round of interaction; if the parsing is successful, proceed to the next step;

[0055] Step S7, if the interactive message is parsed successfully, the parsed data is verified according to the data verification rules of the dispatching master station. The data verification rules of the dispatching master station mainly include data integrity, parameter rationality, data association logic and other related rules. The verification rules are consistent with the source end in principle, and more stringent verification parameters can also be configured according to the needs of the dispatching operation; if the verification fails, the abnormal log is recorded and an alarm is sent, and the verification abnormality information is notified to the source end, and the current round of interaction is terminated; if the verification passes, proceed to the next step;

[0056] Step S8, if the interactive message verification passes, the verified data is stored in the scheduling master station database, and the interactive status is fed back to the source end;

[0057] Step S9, the source end receives the status information fed back by the flexible operation domain data access service of the scheduling master station end, and the process ends normally.

[0058] like Figure 2 As shown, under abnormal circumstances, the power grid dispatching master station needs to supplement the source data:

[0059] Under normal circumstances, the source side actively reports the flexible operation domain related data according to the established logic. However, in the case of interaction failure, data anomalies, stock data access, etc., the power grid dispatching master station needs to supplement the source data. In this scenario, a flexible operation domain data supplement client is established at the power grid dispatching master station, and a flexible operation domain data supplement service is established at each data source or proxy source to monitor the power grid dispatching master station data supplement request; the power grid dispatching master station submits the data supplement request according to the interaction specification and receives the data and status message fed back by the source side. The specific interaction steps are as follows:

[0060] Step S1, the power grid dispatching master station is manually or automatically triggered to start the supplementary recruitment process, and the supplementary recruitment information such as time period range and object range is packaged into a message according to the interaction specification;

[0061] Step S2, sending the supplementary recruitment message to the source-end flexible operation domain data supplementary recruitment service in a request response manner through the scheduling automation system platform service bus;

[0062] Step S3, after receiving the data supplementary recruitment request, the source-side flexible operation domain data supplementary recruitment service queries the local relevant flexible operation domain data;

[0063] Step S4: The source end verifies the feedback data on-site according to the local verification rules. If the verification fails, an abnormal log is recorded and an alarm is issued, and the abnormal state is fed back to the grid dispatching master station, and the supplementary recruitment process ends; if the verification passes, proceed to the next step;

[0064] Step S5: if the source end passes the verification of the data to be fed back, the data to be fed back is encapsulated into a message according to the interaction specification based on the data sending configuration;

[0065] Step S6, sending the feedback message to the dispatching master station in a request response manner through the dispatching automation system platform service bus;

[0066] Step S7: After receiving the feedback message, the data supplementary recruitment client at the power grid dispatching master station records and parses the original data supplementary recruitment feedback message. If an error occurs during the parsing process, an abnormal log is recorded, the current round of supplementary recruitment is terminated, and an alarm is sent to notify the operation and maintenance personnel to handle it in time; if the parsing is successful, the next step is performed;

[0067] Step S8, if the feedback message is parsed successfully, the parsed data is verified according to the data verification rules of the dispatching master station. If the verification fails, an abnormal log is recorded, the current round of supplementary recruitment is terminated, and an alarm is sent to notify the operation and maintenance personnel to handle it in time; if the verification passes, proceed to the next step;

[0068] Step S9: If the feedback message passes the verification, the verified data is stored in the dispatching master station database, and this round of data supplementation is completed.

[0069] The method of the present invention is applicable to coal-fired power flexible operation domain data, and has the characteristics of high interaction efficiency, traceability and strong adaptability.

[0074] The judgment module is used to confirm whether the coal-fired power flexible operation domain data reported by the source end is normal;
