Description

Technical Field

[0001] The present invention belongs to the field of substation microgrid group control, and specifically relates to a coordination control system based on a new energy digital substation microgrid group. Background Art

[0002] A microgrid is a system composed of loads and micro power sources, which usually include distributed power sources such as photovoltaics and wind power generation, and is equipped with an energy management system. It solves problems such as power flow and protection by controlling a large number of power electronic devices. It is required to be able to operate in conjunction with the large power grid, and to disconnect from the main grid when the grid fails or is needed, and to effectively control various distributed power sources. With the rapid development and popularization of new energy, effectively dispatching distributed energy resources through the management of microgrids has become an important challenge in today's energy field.

[0003] Existing microgrids are often managed and coordinated in the form of substations. Each substation corresponds to a management and control module for management and control, which can make full use of the resource sharing characteristics of sources, loads, and storage in the region, enhance the dynamic adjustment ability of regional microgrids, and improve energy utilization efficiency. The management and control methods of each substation in the existing technology usually require the management and control module to obtain and store the operation data of the substation in real time, so as to conduct unified analysis and adjust the resources of each substation.

[0004] For example, the Chinese invention patent with application publication number CN110783915A provides a method and system for powering multiple distribution substations. The main station receives the substation operation information of several distribution substation controllers in real time. When the fault substation information appears, the main station sends a control instruction to the substation controller of the power supply substation to control other substations to supply power to the faulty substation. However, due to the large amount of operation data of multiple substations and the large number of control operations involved in the distribution substation controller, receiving the operation information of all substations and uniformly analyzing and controlling each substation will increase the processing pressure of the control module, making the processing process more prone to errors and failures. Summary of the invention

[0005] The purpose of the present invention is to provide a coordinated control system based on a new energy digital substation microgrid group, which is used to solve the problem of high processing pressure of the control module of the existing substation control method.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a coordinated control system based on a new energy digital substation microgrid group, including a control module and a gateway corresponding to each substation;

[0007] The gateway is used to obtain data from its corresponding area, analyze and process it, and send the analysis and processing results to the control module; it is also used to control the resources of its corresponding area according to the acquired data, its own analysis and processing results and / or the instructions issued by the control module;

[0008] The control module is used to send instructions to the corresponding gateway according to the analysis and processing results sent by the gateway to regulate the resources of each substation.

[0009] The beneficial effects of the above technical solution are: a gateway is set up corresponding to each substation, which can analyze and process its data and perform resource regulation of the corresponding substation, and a management and control module can directly use the data processed and analyzed by the gateway to perform resource regulation of each substation. Therefore, on the basis of ensuring that the management and control module can perform resource regulation of each substation normally, the data analysis pressure and resource regulation pressure of the management and control module can be shared by the gateway with data analysis and substation resource regulation capabilities, thereby avoiding the situation where the management and control module has high processing pressure.

[0010] Furthermore, the management and control module has the authority to access the database corresponding to each area; the database corresponding to each area is used to store the data of the corresponding area obtained by the gateway.

[0011] The beneficial effect of the above technical solution is: by setting up the databases of each gateway separately and the management and control module having the authority to access each database, the management and control module does not have to receive and store the data of each substation to conveniently call and analyze the substation data, thereby greatly reducing the data storage pressure of the management and control module.

[0012] Furthermore, the gateways corresponding to the respective stations only have the authority to access the database corresponding to the station corresponding to the gateway itself.

[0013] The beneficial effect of the above technical solution is that the gateways corresponding to each substation cannot access the database corresponding to other substations, which can effectively prevent data tampering between substations.

[0014] Furthermore, the data of its corresponding substation obtained by the gateway includes remote signaling messages of the substation; the gateway is also used to perform corresponding processing according to the remote signaling messages to regulate the resources of its corresponding substation, and send the remote signaling messages to the management and control module; the management and control module is also used to monitor the gateway after receiving the remote signaling message, and if it is monitored that the gateway fails to perform corresponding processing according to the remote signaling message for more than a certain period of time, the corresponding solution measures are executed.

[0015] The beneficial effects of the above technical solution are: the gateway's processing of remote signaling messages is monitored through the management and control module. If it is monitored that the gateway has not performed corresponding processing based on the remote signaling message for more than a certain period of time, the corresponding solution measures are executed; thereby, abnormal situations such as untimely processing or erroneous processing when the gateway processes the remote signaling message can be discovered in time, so that corresponding measures can be executed in time to avoid further expansion of the negative impact of the abnormal situation.

[0016] Furthermore, the remote signaling message of the substation includes information that needs to be processed by regulating resources of other substations, and the gateway processes the remote signaling message by sending a regulation application to the control module after receiving the information, and analyzing and obtaining the regulation data corresponding to the information;

[0017] The control module is used to obtain the control data analyzed by the gateway after receiving the control application, and send corresponding instructions to the corresponding gateway to control the resources of each substation based on the control data and the data in the database corresponding to other gateways.

[0018] The beneficial effects of the above technical solution are: for information that needs to be processed by regulating the resources of other substations, a regulation application is sent to the management and control module through the gateway, and the regulation data corresponding to the information is analyzed. The management module can respond to the regulation application using the analysis results of the gateway to perform resource regulation between substations; therefore, on the basis of sharing the data processing and storage pressure of the management and control module as much as possible through the gateway and the database corresponding to the gateway, the realization of resource regulation between substations does not depend on information interaction between substations.

[0019] Furthermore, the gateway is also used to send a corresponding signal of starting processing to the control module when starting to perform corresponding processing according to the remote signaling message, and send a corresponding signal of completing processing to the control module after the processing is completed;

[0020] The management and control module monitors the gateway after receiving the remote signaling message, including: starting timing when the remote signaling message is received, and executing corresponding solutions if the corresponding signal for starting processing is not received within the first set time; otherwise, continuing timing, and ending monitoring if the corresponding signal for ending processing is received within the second set time, otherwise executing corresponding solutions.

[0021] The beneficial effect of the above technical solution is: through the gateway actively sending the corresponding signal of starting processing and the corresponding signal of ending processing, the situation of the gateway performing corresponding processing according to the remote signal message can be obtained in time, thereby ensuring the real-time monitoring of the gateway.

[0022] Furthermore, the corresponding solution measures executed by the management and control module include: issuing an urging processing command to the corresponding gateway, and issuing an alarm to request manual intervention.

[0023] The beneficial effect of the above technical solution is: it not only tries to solve the problem of untimely gateway processing by issuing a prompt processing command to the corresponding gateway, but also issues a request for manual intervention, that is, different solutions are set at the same time to complement each other and try to avoid the situation where the solutions fail.

[0024] Furthermore, the control module is also used to obtain relevant data from the database corresponding to each substation, analyze the data in combination with each substation, and send instructions to the corresponding gateway according to the analysis results to regulate the substation resources.

[0025] The beneficial effect of the above technical solution is: when the gateway only has the authority to access the database corresponding to its own substation and can only obtain relevant data of the substation, which makes it difficult to regulate resources between substations, through the management and control module with the authority to access the database corresponding to each substation, the relevant data of each substation can be directly obtained from the database for regulation, thereby achieving comprehensive analysis of the data of each substation, facilitating timely resource regulation between each substation.

[0026] Furthermore, the management and control module also includes a human-computer interaction submodule for displaying the analysis and processing results sent by the gateway.

[0027] The beneficial effect of the above technical solution is that the data processing and analysis results of each gateway can be uniformly displayed in the management and control module, making it easy to obtain the data processing and analysis results of each gateway intuitively and visually.

[0028] Furthermore, the human-computer interaction submodule is also used to display the remote signaling message sent by the gateway.

[0029] The beneficial effect of the above technical solution is that the remote signaling messages of the substations sent by each gateway can be displayed through the management and control module, which is convenient for intuitively and visually obtaining the remote signaling messages of the substations sent by each gateway, and is also convenient for manual control of the resources of each substation.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0036] Implementation example of coordinated control system based on new energy digital substation microgrid group

[0037] This embodiment provides a technical solution for a coordinated control system based on a new energy digital substation microgrid group. Figure 1 The coordinated control system includes a control module (also called a microgrid group coordinated control module) and a gateway corresponding to each substation; each substation in this embodiment is a small AC grid-connected microgrid module, refer to Figure 2 The station area structure is such that each station area is connected to its corresponding gateway (communication connection in this embodiment).

[0038] The gateway is used to obtain data from its corresponding area, perform analysis and processing, and send the analysis and processing results to the management and control module; it is also used to regulate the resources of its corresponding area based on the acquired data from its corresponding area, its own analysis and processing results and / or instructions issued by the management and control module; specifically, each gateway has the functions of collecting data, controlling, and coordinating resources for its corresponding area.

[0039] The control module is used to send instructions to the corresponding gateway according to the analysis and processing results sent by the gateway, so as to regulate the resources of each substation. It can be seen that the coordination and control system of this embodiment is equipped with gateways corresponding to each substation, which can analyze and process the data of the corresponding substation and regulate the resources of the corresponding substation, and the control module can directly use the data processed and analyzed by the gateway to regulate the resources of each substation. In this way, on the basis of ensuring that the control module can regulate the resources of each substation normally, the gateway with data analysis and substation resource regulation capabilities can share the data analysis pressure and resource regulation pressure of the control module, thereby avoiding the situation where the control module has a large processing pressure.

[0040] The control module has the authority to access the database corresponding to each substation, where the database corresponding to each substation is used to store the data of the corresponding substation obtained by the gateway; in this embodiment, the database corresponding to each substation is part of the coordination control system, and in other embodiments, other existing databases can be used as the database corresponding to each substation to store the data of the corresponding substation obtained by the gateway; thereby, by setting up the databases corresponding to each substation and the authority of the control module to access each database, the control module does not have to store the data of each substation and can conveniently call and analyze the substation data, thereby greatly reducing the data storage pressure of the control module; and, in this embodiment, the gateway corresponding to each substation only has the authority to access the database corresponding to the substation corresponding to the gateway itself, which can effectively prevent the behavior of tampering with data between substations.

[0041] In this embodiment, the management and control module is also used to obtain relevant data from the database corresponding to each substation, analyze the data in combination with each substation, and issue instructions to the corresponding gateway according to the analysis results to regulate the substation resources; since the gateway only has the authority to access the database corresponding to its own substation, the gateway can only obtain the relevant data of its own substation and can only analyze the data of its own substation, and cannot perform a comprehensive analysis in combination with the data of each substation. Therefore, through the management and control module with the authority to access the database corresponding to each substation, the relevant data of each substation is directly obtained from the database, thereby realizing comprehensive analysis of the data of each substation, facilitating timely resource regulation between each substation.

[0042] Specifically, from the overall structure, first, the control module is connected to multiple substation gateways. Each substation gateway first analyzes and processes the data of the substation, and then uploads it to the control module; secondly, the control module has the database permissions corresponding to all substations, while the substation gateway only has the permissions of its own database; then, each gateway has the functions of collecting data, controlling, and coordinating resources for its corresponding substation. The control module has the greatest authority and can manage all substations. The instructions issued by the control module are called first-level instructions, and the instructions issued by the gateway are called second-level instructions. The control module can perform actions or allocate resources for the substation by issuing instructions to the gateway. It has the highest authority to achieve resource regulation of each substation.

[0043] Among them, the data of its corresponding substation acquired by the gateway includes the remote signaling message of the substation; the gateway is also used to perform corresponding processing according to the remote signaling message to regulate the resources of its corresponding substation, such as issuing remote control and remote adjustment commands to regulate the resources of the substation, and sending the remote signaling message to the control module; the control module is also used to monitor the gateway after receiving the remote signaling message. If it is monitored that the gateway has not performed corresponding processing according to the remote signaling message for more than a certain period of time, the corresponding solution measures are executed; thereby, it is possible to timely discover abnormal situations such as untimely processing or processing errors when the gateway processes the remote signaling message, so as to timely execute corresponding measures to avoid further expansion of the negative impact of the abnormal situation. In other embodiments, the data of the corresponding substation acquired by the gateway can also include telemetry messages of the substation, and the processing method and effect are the same as those of the remote signaling message.

[0044] The gateway is also used to send a corresponding signal of starting processing to the control module when starting to process the remote signal message, and send a corresponding signal of ending processing to the control module after the processing is completed;

[0045] The way in which the control module monitors the gateway after receiving the remote signaling message includes: starting the timing when the remote signaling message is received, and executing the corresponding solution if the corresponding signal for starting the processing is not received within the first set time; otherwise, continuing the timing, and ending the monitoring if the corresponding signal for ending the processing is received within the second set time, otherwise executing the corresponding solution. In this embodiment, the corresponding solution executed by the control module includes: issuing a processing urging command to the corresponding gateway, and issuing an alarm to request manual intervention. It can be seen that through the corresponding signal for starting the processing and the corresponding signal for ending the processing actively sent by the gateway, the control module can promptly obtain the situation that the gateway performs corresponding processing according to the remote signaling message, thereby ensuring the real-time monitoring of the gateway; and, not only by issuing a processing urging command to the corresponding gateway to try to solve the problem of untimely processing of the gateway, but also by issuing a processing urging command to request manual intervention, that is, setting different solutions to complement each other and try to avoid the situation where the solutions fail.

[0046] Specifically, the remote signaling message takes the alarm information as an example, refer to Figure 3 , the specific working mode of the above-mentioned gateway and control module after receiving the remote signaling message is described:

[0047] The substation reports the alarm to the substation gateway. After the gateway collects the alarm information of the substation, on the one hand, it stores the data corresponding to the alarm information in the database; on the other hand, it regulates the substation resources according to the alarm information; in addition, the data corresponding to the alarm information is directly sent to the control module. The control module starts timing after receiving the data corresponding to the alarm information. When the control module does not receive the message sent by the gateway to start processing the alarm (i.e., start processing the corresponding signal) within t1 time (i.e., the first set time), it means that the gateway has not started processing the alarm information in time, and the control module sends a urging processing command to the gateway, and issues an alarm to request manual intervention. If the control module receives the alarm processing message sent by the gateway within t1 time, it will continue to count and determine whether it has received the message of completing the alarm processing (i.e., the corresponding signal of completing the processing) within t2 time (i.e., the second set time). If it is received, the monitoring process of the alarm message will be terminated. If it is not received, it means that the gateway has not completed the processing of the alarm information in time, and a urging processing command will be issued to the corresponding gateway, and an alarm will be issued to request manual intervention.

[0048] Considering that the data processing and analysis results of each gateway are distributed at each gateway and are difficult to obtain intuitively, in this embodiment, the management and control module also includes a human-computer interaction submodule for displaying the analysis and processing results sent by the gateway; for example Figure 4 As shown, the human-computer interaction submodule is a display screen. The gateway obtains data from its corresponding database or substation, and then analyzes and processes the data. After obtaining the analyzed and predicted data results, it reports them to the control module. The control module summarizes the analyzed and predicted data results reported by the gateways corresponding to each substation and displays them on the display screen, that is, displays the data results analyzed by the control module, so that users can see the analyzed and predicted data results such as wind power generation losses in each substation; in this embodiment, the human-computer interaction submodule is also used to display the remote signaling messages sent by the gateway. In this way, the data processing and analysis results of each gateway and the remote signaling messages of the substation can be displayed uniformly at the control module, for example, the data uploaded to the human-computer by the control module can be directly displayed for maintenance personnel to view, such as the alarm message in the remote signaling message; thus, it is convenient to intuitively and visually obtain the data processing and analysis results of each gateway and the remote signaling messages of the substation. The human-computer interaction submodule can also be used for manual resource control, such as manually issuing instructions to the control module, so that the control module issues corresponding instructions to control a certain substation to send power to the transmission line.

[0049] In this embodiment, the remote signaling message of the substation includes information (usually alarm information) that needs to be processed by regulating the resources of other substations, such as the alarm information that the power generation of the substation is insufficient to supply the corresponding load. The resource regulation between substations based on such information must rely on the information interaction between substations; and in order to avoid the risk of data tampering caused by the data interaction between substations, the gateway only has the authority to access the database corresponding to its own substation, so the gateway can only obtain the relevant data of the substation, which makes it difficult to regulate the resources between substations, and it is difficult to meet the regulation requirements of information such as the alarm information that the power generation of the substation is insufficient to supply the corresponding load. The processing of the remote signaling message by the gateway includes sending a regulation application to the control module after receiving the information that needs to be processed by regulating the resources of other substations, and analyzing and obtaining the regulation data corresponding to the information;

[0050] The control module is used to obtain the control data analyzed by the gateway after receiving the control application, and according to the control data and the data in the database corresponding to other gateways, issue corresponding instructions to the corresponding gateway to control the resources of each substation; for example, if the information that needs to be processed by regulating the resources of other substations is the alarm information corresponding to the power generation of the substation is insufficient to supply the load, then the corresponding operation of regulating the resources of each substation is to regulate the supply of electricity. In summary, the control data corresponding to the alarm information is first obtained through gateway analysis, and then the control data obtained by the gateway analysis and the data in the database corresponding to other gateways are obtained through the control module with the authority of all substation databases (that is, the databases corresponding to each gateway). On the basis of sharing the data processing and storage pressure of the control module as much as possible through the gateway and the database corresponding to the gateway, the realization of resource control between substations does not rely on the information interaction between substations.

[0051] Specifically, taking the alarm information corresponding to the power generation in the substation area being insufficient to supply the load as an example, refer to Figure 5 , the above working method is explained:

[0052] For some reason, the power generation of area 2 is insufficient to supply the load and an alarm is issued. After receiving the alarm, the gateway applies to the management and control module for regulating the power supply. After receiving the application, the management and control module first asks the gateway about the required power supply and other conditions, and then calculates the resource allocation based on the feedback and the conditions of other areas. For example, the calculation result is that the power Q required by area 2 will be supplied by area 1, then the management and control module will issue a command to the gateway corresponding to area 1 to transmit the power to the transmission line. The gateway of area 2 receives the reply of the available power sent by the management and control module (such as the reply of the power supplied by area 1), and then the two areas are controlled by the gateway to open their switch controllers to send or receive power.

[0053] The control module obtains relevant data from the database corresponding to each substation, analyzes the data of each substation, and issues instructions to the corresponding gateway according to the analysis results to regulate the substation resources. The working method is similar to the above working method, so it is also explained by the example of the alarm information corresponding to the substation power generation being insufficient to supply the load. For example, after the control module obtains relevant data from the database corresponding to each substation, it is found through analysis that the load of substation 2 is heavy and its power generation is insufficient to supply itself, while substation 1 is closest to substation 2, and has large power generation and small load. Then the control module will long-term regulate the power supply of substation 1 to substation 2, that is, long-term command is issued to the gateway corresponding to substation 1 to transmit power to substation 2. At the same time, the gateway corresponding to substation 2 receives the reply of the available power sent by the control module (such as the reply of power supplied by substation 1), and then the two substations are controlled by the gateway to open their switch controllers to send or receive power.

[0054] In this embodiment, based on the functions of the above-mentioned control module, the control module can also be used to obtain data from each area for overall analysis to predict resource allocation and regulation for the next month or the next year; and the control module can continuously obtain actual data from each area database, so it can be used as a data source interface to continuously obtain actual data for training prediction model algorithms, etc. That is, the control module of this embodiment can have the functions of monitoring areas, regulating area resources, analyzing and displaying data, and serving as a data source interface.

[0055] The present invention has the following characteristics:

[0056] 1) A gateway corresponding to each substation is set up, which can analyze and process the data of the corresponding substation and perform resource regulation of the corresponding substation, and a management and control module can directly use the data processed and analyzed by the gateway to perform resource regulation of each substation. In this way, on the basis of ensuring that the management and control module can normally perform resource regulation of each substation, the gateway with data analysis and substation resource regulation capabilities can share the data analysis pressure and resource regulation pressure of the management and control module, thereby avoiding the situation where the management and control module has a large processing pressure.

[0057] 2) By setting up databases corresponding to each substation and giving the management and control module access to each database, the management and control module does not have to store the data of each substation and can conveniently call and analyze the substation data, thereby greatly reducing the data storage pressure of the management and control module; and the gateway corresponding to each substation only has the authority to access the database corresponding to the substation corresponding to the gateway itself, which can effectively prevent data tampering between substations.

[0058] 3) When the gateway receives the telesignaling message, it not only processes the message accordingly to regulate the resources of the corresponding substation, but also sends the message to the control module. The control module also monitors the gateway after receiving the telesignaling message. If it is monitored that the gateway has not processed the message accordingly for more than a certain period of time, the corresponding solution measures will be executed. In this way, abnormal situations such as untimely processing or erroneous processing when the gateway processes the telesignaling message can be discovered in time, so that corresponding measures can be executed in time to avoid further expansion of the negative impact of the abnormal situation.

[0059] 4) The control module is also equipped with a human-computer interaction submodule for displaying the analysis and processing results and telesignaling messages sent by the gateway. This enables the data processing and analysis results of each gateway and the telesignaling messages of the substation area to be displayed uniformly in the control module, making it easy to intuitively and visually obtain the data processing and analysis results of each gateway and the telesignaling messages of the substation area.

[0060] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, but do not constitute a limitation to the present invention.
