Technical Field

[0001] The present invention relates to a data interaction method and system, and in particular to a data interaction method and system for an electric-hydrogenation coupling system to participate in power grid optimization dispatching operation. Background Art

[0002] New energy sources, mainly wind power and photovoltaic power, have developed rapidly. Their power generation is highly random, intermittent and volatile. Under the new power system, the contradiction between the difficulty of absorbing new energy when it is generated in large quantities and the difficulty of ensuring power supply when it is generated in small quantities is highlighted. The traditional source-follow-load generation-side dispatching mode is no longer applicable. Although there are currently studies on optimization models for new resources such as hydrogenation to participate in grid dispatching and operation, due to the particularity and complexity of the model and system of hydrogenation coupling system, there is no solution for how the existing grid dispatching control system can access and process the model attribute parameters and operation data of hydrogenation coupling system. Summary of the invention

[0006] The file interaction is to transmit the model information to the specified file path after security isolation through the CIM / E file; the verification rules of the file interaction method are: after the data receiving end completes data reception, it sends a confirmation message to the data sending end that the data has been received; after the data sending end obtains the confirmation message, the entire file transmission process is completed; if the data sending end does not receive the confirmation message from the data receiving end within the specified time, it sends the file again; when the number of times the data sending end sends the file reaches the set maximum number of retransmissions, the data sending end issues a relevant alarm and saves the sending time, address, and file content information;

[0007] The service-oriented interaction is that the data sending end and the receiving end agree on a fixed interaction message format, and realize online point-to-point direct data interaction between the sending end and the receiving end through a communication protocol; the verification rule of the service-oriented interaction method is that the data sending end first sends encrypted transmission data information to the data receiving end, which is confirmed by the data receiving end; the data receiving end transmits the confirmed data information back to the data sending end for confirmation by the data sending end, and the data receiving end receives and parses the data information after receiving the confirmation message.

[0008] As a preferred solution of the data interaction method for the electric hydrogenation coupling system participating in the power grid optimization dispatching operation described in the present invention, the physical attribute information of the electric hydrogenation coupling system includes: system name, system type, system rated capacity, system maximum power, system minimum power, system start and stop time, system upper regulation rate, system lower regulation rate, and the name of the busbar of the system connected to the power grid booster station;

[0009] The economic attribute information of the electric-hydrogenation coupling system includes: the adjustable range, startup cost and operating cost of the economic operation of the electric-hydrogenation coupling system; the startup cost refers to the cost required for starting the operation of the electric-hydrogenation coupling system when it is initially in different states, including cold startup cost and hot startup cost; the operating cost refers to the cost required for the electric-hydrogenation coupling system to output different active powers; the adjustable range is the economic constraint condition for the regulation of the electric-hydrogenation coupling system.

[0015] (2) After receiving the encrypted interactive data, the electric-hydrogen coupling system decrypts and confirms the interactive data and returns the encrypted interactive data to the power grid dispatching and control system;

[0016] (3) When the grid dispatching and control system receives the encrypted interactive data returned by the electric-hydrogen coupling system, it performs a decryption operation and compares it with the sent data. If the comparison is inconsistent, it fails and terminates the interactive process; if the comparison is consistent, it issues a data interactive confirmation instruction;

[0017] (4) If the electric-hydrogen coupling system exceeds the preset maximum waiting time for receiving instructions and still has not received the data exchange confirmation instruction, it will automatically terminate data reception; otherwise, after receiving the data exchange confirmation instruction issued by the power grid dispatching and control system, it will reply with a data reception confirmation instruction.

[0027] Figure 2 It is a schematic diagram of the data interaction verification process described in the present invention. DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] Example 1

[0030] The data interaction method for the electric hydrogenation coupling system participating in the power grid optimization dispatching operation of the present invention is used for the data interaction between the electric hydrogenation coupling system and the power grid dispatching control system, comprising: classifying the interaction data between the electric hydrogenation coupling system and the power grid dispatching control system into: model information, measurement data, control information and plan data, wherein the model information includes physical attribute information and economic attribute information of the electric hydrogenation coupling system;

[0031] Among them, the physical property information of the electric-hydrogen coupling system is exchanged in the form of file interaction, and the economic property information of the electric-hydrogen coupling system is exchanged in the form of file interaction or service interaction; the measurement data and control data are exchanged through the network protocol of the power system; the planning data is exchanged in the form of file interaction or service interaction;

[0032] The file interaction is to transmit the model information to the specified file path after security isolation through the CIM / E file. The verification rules of the file interaction method are as follows: after the data receiving end completes data reception, it sends a confirmation message to the data sending end that the data has been received; after the data sending end obtains the confirmation message, the entire file transmission process is completed; if the data sending end does not receive the confirmation message from the data receiving end within the specified time, it sends the file again; when the number of times the data sending end sends the file reaches the set maximum number of retransmissions, the data sending end issues a relevant alarm and saves the sending time, address, and file content information;

[0033] The service-oriented interaction is that the data sending end and the receiving end agree on a fixed interaction message format, and realize online point-to-point direct data interaction between the sending end and the receiving end through a communication protocol. The verification rule of the service-oriented interaction method is that the data sending end first sends encrypted transmission data information to the data receiving end, which is confirmed by the data receiving end; the data receiving end transmits the confirmed data information back to the data sending end for confirmation by the data sending end, and the data receiving end receives and parses the data information after receiving the confirmation message.

[0034] The following is a detailed explanation of the three aspects of data interaction content, data interaction processing method and data interaction verification mechanism.

[0035] 1. Data interaction content.

[0036] The first step is to determine the data content of the interaction between the existing power grid dispatching and control system and the electric hydrogenation coupling system. Based on the business needs of the electric hydrogenation coupling system to participate in the dispatching and operation of power grid peak regulation and frequency regulation, the interaction content between the electric hydrogenation coupling system and the power grid dispatching and control system is designed to support the flexible collection of real-time data and planned data of the electric hydrogenation coupling system and the effective interaction of adjustment instructions.

[0037] Data interaction content refers to the key information that the existing power grid dispatching and control system should access or issue in order to include the electric-hydrogen coupling system as an adjustable resource in operation monitoring, planning (market clearing), and dispatching control. It mainly includes four aspects: model information, measurement data, control information, and planning data, as shown in Table 1.

[0038] Table 1

[0039]

[0040] Among them, model information and measurement data are mainly data transmitted by the electric-hydrogen coupling system to the power grid dispatching and control system; while control information and planning data are mainly data transmitted by the power grid dispatching and control system to the electric-hydrogen coupling system.

[0041] In terms of model information, it mainly includes two parts:

[0042] ① Physical property information of the electric-hydrogen coupling system: related to physical characteristics, including model attributes such as equipment name, equipment type, rated capacity, maximum power, minimum power, start and stop time, upper regulation rate, lower regulation rate, and bus name of the booster station connected to the power grid;

[0043] ② Economic attribute information of the electric-hydrogen coupling system: Usually, when the power grid dispatching and control system plans (market clearing) adjustable resources, in addition to satisfying the physical operating characteristics of the adjustable resources themselves, it is also necessary to consider the operating economy of the participating entities. Therefore, it also includes information such as the adjustable range, startup cost, and operating cost of the economic operation of the electric-hydrogen coupling system; the startup cost of the electric-hydrogen coupling system refers to the cost required to start the operation of the electric-hydrogen coupling system when it is initially in different states, usually including cold start-up costs and hot start costs; the operating cost of the electric-hydrogen coupling system refers to the cost required for the electric-hydrogen coupling system to output different active powers.

[0044] In terms of measurement data, it mainly accesses the real-time changing data of the electric-hydrogen coupling system during operation, including voltage, current, upward / downward adjustment margin, operating status, real-time gas pressure of the hydrogen storage tank, hydrogen production rate, hydrogen production volume, etc.

[0045] In terms of planning data, it is mainly the active power that the electric-hydrogen coupling system should output in the future after the grid dispatching control system has made plans (market clearing), usually in the next 2-4 hours or the next day. For the market clearing calculation results, the price information of the call should also be given.

[0046] In terms of control information, it is mainly the real-time operation control instruction information given by the power grid dispatching and control system based on the real-time operation status and planning data of the power grid, including control target power, start time, end time, and response duration.

[0047] 2. Data interaction processing method.

[0048] (1)Data interaction method.

[0049] The physical property information of the electric-hydrogen coupling system is transmitted to the specified file path of the power grid dispatching and control system through CIM / E files after secure isolation of the model information, and the power grid dispatching and control system regularly monitors and updates the relevant model information; the economic property information is reported through the trading client or the grid-plant interaction platform, and the relevant information is encrypted and transmitted to the power grid dispatching and control system in a service-oriented manner, and some information is encrypted and interacted through file interaction. Service-oriented interaction means that the data sender and the receiver agree on a fixed interactive message format, and realize direct online point-to-point data interaction between the sender and the receiver through communication protocols such as WebService and https. The trading client and the grid-plant interaction platform are tools provided by the control system that can directly perform the service functions of the data sender / receiver.

[0050] The measured data of the electric-hydrogen coupling system is uploaded through the 104 network protocol. At the same time, the electric-hydrogen coupling system receives the control information given by the power grid dispatching control system through the 104 network protocol. The planned data is encrypted and interacted through files or services. The relevant cost / price information is reported and viewed on the transaction client or the grid-factory interaction platform.

[0051] (2) Calculation data processing format of power grid dispatching control system.

[0052] At present, the power grid dispatching and control system calls the optimization calculation solution service to complete the calculation during the planning (market clearing). The power grid dispatching and control system extracts the economic attribute information of the electric-hydrogen coupling system from the data server, generates an E-format file according to the following attribute format, and packages this file with the conventional unit file and transmits it to the server where the optimization calculation service is located.

[0053]

[0054] 3. Data interaction verification mechanism.

[0055] In order to ensure the security of data interaction, different interaction verification mechanisms are built for file interaction and service interaction.

[0056] (1) For the file interaction mode, the following verification rules are adopted:

[0057] ①Interaction channel status verification:

[0058] like Figure 1 As shown in the figure, the channel status adopts a two-way forwarding verification mechanism, and the data interaction ends A and B send status requests periodically. Taking A as the sender and B as the responder as an example, after B receives the request sent by A, B immediately returns the response status file; after A sends the status request file, if it cannot receive a response within the specified time, it is considered that the interaction channel is abnormal, and an alarm prompt is issued on the A end. At this time, A stops sending data. The monitoring cycle, sending and response status file format specifications are agreed upon by both ends.

[0059] ② Verify basic information of monitoring files:

[0060] The data sender generates a data file and sends it to the specified directory of the data receiver's system. The data receiver reads the data file and determines whether the file format content conforms to the agreed format. If it does not conform to the agreed format, the data file parsing process is exited;

[0061] The data receiver reads the data file and the time it was received. If the time it was received exceeds the agreed deadline, the data file parsing process is stopped.

[0062] ③ File interaction status verification:

[0063] like Figure 2 As shown, after the data receiver completes data reception, it sends a confirmation message to the data sender that the data has been received. The data sender waits for the receiver's feedback confirmation message to complete the entire file transfer process. If the receiver's confirmation message is not received within the specified time, the previously failed file is sent again until the set maximum number of retransmissions is reached. The sender then issues a related alarm and saves information such as the sending time, address, and file content.

[0064] (2) For interaction in a service-oriented manner, the following mechanism is adopted:

[0065] Taking the data transmission from the power grid dispatching control system to the electric hydrogenation coupling system as an example, the interactive verification process is explained. Figure 2 As shown, the power grid dispatching and control system first sends encrypted transmission data information to the electric hydrogenation coupling system, which is confirmed by the electric hydrogenation coupling system; the electric hydrogenation coupling system transmits the confirmed data information back to the power grid dispatching and control system for confirmation. After receiving the confirmation message, the electric hydrogenation coupling system receives and parses the data information. The specific requirements are as follows:

[0066] (a) The grid dispatching and control system sends encrypted interactive data to the electric hydrogenation coupling system;

[0067] (b) After receiving the encrypted interactive data, the electric hydrogenation coupling system decrypts and confirms the interactive data and returns the encrypted interactive data to the power grid dispatching and control system;

[0068] (c) When the grid dispatching and control system receives the encrypted interactive data returned by the electric-hydrogen coupling system, it performs a decryption operation and compares it with the sent data. If the comparison is inconsistent, it fails and terminates the interactive process; if the comparison is consistent, it issues a data interactive confirmation instruction;

[0069] (d) If the electric-hydrogen coupling system exceeds the preset maximum waiting time for receiving instructions and still does not receive the data interaction confirmation instruction, it will automatically terminate data reception; otherwise, after receiving the data interaction confirmation instruction issued by the power grid dispatching and control system, it will reply with a data reception confirmation instruction.

[0070] Example 2

[0071] The data interaction system of the electric hydrogenation coupling system participating in the power grid optimization dispatching operation of the present invention includes a data sending end and a data receiving end of the power grid dispatching control system, and a data sending end and a data receiving end of the electric hydrogenation coupling system. The interactive data between the electric hydrogenation coupling system and the power grid dispatching control system are classified into: model information, measurement data, control information and planning data, and the model information includes physical attribute information and economic attribute information of the electric hydrogenation coupling system;

[0072] Among them, the physical property information of the electric-hydrogen coupling system is exchanged in the form of file interaction, and the economic property information of the electric-hydrogen coupling system is exchanged in the form of file interaction or service interaction; the measurement data and control data are exchanged through the network protocol of the power system; the planning data is exchanged in the form of file interaction or service interaction;

[0073] The file interaction is to transmit the model information to the specified file path after security isolation through the CIM / E file. The verification rules of the file interaction method are as follows: after the data receiving end completes data reception, it sends a confirmation message to the data sending end that the data has been received; after the data sending end obtains the confirmation message, the entire file transmission process is completed; if the data sending end does not receive the confirmation message from the data receiving end within the specified time, it sends the file again; when the number of times the data sending end sends the file reaches the set maximum number of retransmissions, the data sending end issues a relevant alarm and saves the sending time, address, and file content information;

[0074] The service-oriented interaction is that the data sending end and the receiving end agree on a fixed interaction message format, and realize online point-to-point direct data interaction between the sending end and the receiving end through a communication protocol. The verification rule of the service-oriented interaction method is that the data sending end first sends encrypted transmission data information to the data receiving end, which is confirmed by the data receiving end; the data receiving end transmits the confirmed data information back to the data sending end for confirmation by the data sending end, and the data receiving end receives and parses the data information after receiving the confirmation message.
