[0001] The present invention relates to the technical field of power distribution optimization, and in particular to an active power distribution optimization management system for a clustered microgrid. Background Art

[0002] With the growth of energy demand and the increasingly severe environmental problems, microgrids, as a distributed power system integrating renewable energy, energy storage systems and loads, are gaining more and more attention. Clustered microgrids are composed of multiple microgrids. Through interconnection and coordinated operation, resources can be used more efficiently and power supply reliability can be improved. However, due to the uncertainty of renewable energy and the volatility of loads, the distribution management of clustered microgrids faces many challenges, especially for the optimization of power loads in each grid area in clustered microgrids. How to achieve active and efficient distribution management so that clustered microgrids can operate continuously and reliably is a top priority. Summary of the invention

[0003] In order to solve the above problems, an object of the present invention is to provide an active power distribution optimization management system for a clustered microgrid.

[0004] The object of the present invention can be achieved by the following technical solutions: An active power distribution optimization management system for a clustered microgrid, comprising a management center, wherein the management center is communicatively connected with a data acquisition module, a load prediction module, a decision module, and a control execution module;

[0005] The data acquisition module is used to establish power acquisition nodes for each grid area in the clustered microgrid, and integrate all power acquisition nodes to build a power data acquisition network, and collect power data sets corresponding to the entire clustered microgrid through the power data acquisition network;

[0006] The load prediction module is used to predict the power load status of each grid area included in the clustered microgrid according to the power data set, and generate a grid operation log report corresponding to each grid area, and transmit the grid operation log report to the decision optimization module through the internal communication network;

[0007] The decision module is used to perform data analysis based on the power grid operation log report of each power grid area, and then decide on the power equipment operation strategy corresponding to each power grid area;

[0008] The control execution module is used to construct a corresponding device control set according to the power equipment operation strategy corresponding to each power grid area, and remotely control the corresponding power equipment in each power grid area under the clustered microgrid area through the device control set.

[0009] Furthermore, the process of establishing power collection nodes for each grid area in the clustered microgrid and integrating all power collection nodes to build a power data collection network includes:

[0010] The clustered microgrid is divided into several grid areas and numbered, and the number is recorded as i, i=1, 2, 3, ..., n, where n is a natural number greater than 0. Starting from i=1, the value of i is increased by 1 each time, and each grid area is traversed in turn, and then the power collection node corresponding to each grid area is established, and a terminal network is set up. The power collection node in each grid area submits a network access application to the terminal network. The network access application submitted by each power collection node carries the regional information of its own grid area. The terminal network reviews the network access application. When the review is passed, part of the network computing power corresponding to the current terminal network is allocated to the power collection node that submitted the network access application; if the review fails, no operation is performed, and a communication path is established between each two adjacent power collection nodes, and then a communication path is established between any two adjacent power collection nodes. All power collection nodes are integrated through the communication path, and then a power data collection network is built.

[0011] Furthermore, the process of collecting the power data set corresponding to the entire cluster microgrid through the power data collection network includes:

[0012] The power equipment in the grid area that is in operation under the current cluster microgrid is located, and the corresponding power collection nodes in the power data collection network are dispatched. The power operation data corresponding to the current grid area is obtained through the power collection nodes. The power operation data includes the operating time, operating voltage, operating power and operating current corresponding to the operation of each power equipment in the grid area. The power equipment corresponding to the grid area that is not in operation under the cluster microgrid is located, and the power collection nodes corresponding to the grid area in the power data collection network are set to silent state. The power operation data corresponding to each grid area are integrated as the power data set corresponding to the current entire cluster microgrid, and the power data set is sent to the load prediction module.

[0013] Furthermore, the process of predicting the power load status of each grid area included in the clustered microgrid according to the power data set and generating a grid operation log report for each grid area includes:

[0014] The regional operation coefficient corresponding to each power grid area is obtained through the power operation data of each power grid area. The regional operation coefficient of the i-th power grid area is recorded as τ[i], and the operation time, operation voltage, operation power and operation current in the power operation data are recorded as T 运行 、V 运行 , W 运行 and A 运行, set the critical threshold of duration, critical threshold of voltage, critical threshold of power and critical threshold of current, and record them as T 阈值 、V 阈值 , W 阈值 and A 阈值 ;

[0015] When T 运行 ≤T 阈值 , V 运行 ≤V 阈值 , W 运行 ≤W 阈值 and A 运行 ≤A 阈值 When both are true, the regional operation coefficient τ[i] takes the value of 1. 运行 ≤T 阈值 , V 运行 ≤V 阈值 , W 运行 ≤W 阈值 and A 运行 ≤A 阈值 When at least one of the above conditions is not true, the regional operation coefficient τ[i] takes the value of 0;

[0016] The power load status of the power grid area includes a suitable load status and a load overload status; when the regional operation coefficient τ[i] of the power grid area is 0, the corresponding power grid area is in a load overload status; when the regional operation coefficient τ[i] of the power grid area is 1, the corresponding power grid area is in a suitable load status; a blank report file is bound to each power grid area, a monitoring period is set, and all power operation data of each power grid area during the monitoring period are entered into the corresponding bound blank report files, thereby generating a power grid operation log report corresponding to each power grid area.

[0017] Furthermore, the process of transmitting the power grid operation log report to the decision optimization module through the internal communication network includes:

[0018] Construct an internal communication network, which includes several internal communication links. Each internal communication link is used to capture a power grid operation log report corresponding to a power grid area and determine whether the power grid operation log report carries external attack information.

[0019] If so, the external attack information is input into the set security protection program, and the security protection program records the security response instructions corresponding to several sub-attack information items included in the external attack information, and records the security handling steps corresponding to each security response instruction. The security protection program retrieves several security response instructions corresponding to the current external attack information, and then handles the external attack information through the security handling steps corresponding to all security response instructions; after the power grid operation log is processed, the external attack information is removed, and an internal access code is bound to the power grid operation log. After the internal communication link obtains the internal access code, the power grid operation log is transmitted to the decision optimization module through the internal communication link;

[0020] If not, an internal access code is directly bound to the power grid operation log, and the power grid operation log carrying the internal access code is transmitted through the corresponding internal communication link.

[0021] Furthermore, the process of performing data analysis based on the grid operation log report of each grid area and then deciding the power equipment operation strategy corresponding to each grid area includes:

[0022] The grid operation log reports corresponding to the grid areas in the overload state are marked as abnormal reports to be analyzed, and the corresponding abnormal analysis network is constructed; the grid operation log reports corresponding to the grid areas in the appropriate load state are marked as reports to be supervised and analyzed, and the corresponding supervision network is constructed;

[0023] The power equipment operation strategy includes the first equipment operation strategy and the second equipment operation strategy. The abnormal analysis network is used to perform data analysis on the abnormal report to be analyzed, and the first equipment operation strategy corresponding to the power grid area with overload status is decided. The supervision network is used to perform data analysis on the supervision analysis report, and the second equipment operation strategy corresponding to the power grid area with suitable load status is decided.

[0024] Furthermore, the process of constructing an abnormal analysis network and a supervision network, and then respectively deciding on the corresponding first device operation strategy and the second device operation strategy includes:

[0025] The abnormal analysis report records the equipment information corresponding to each power equipment in abnormal operation in the power grid area, sets an abnormal analysis node for each abnormal power equipment, and enters the equipment information of each power equipment into the respective abnormal analysis node, integrates all abnormal analysis nodes in the same power grid area, and then constructs an abnormal analysis network for the corresponding power grid area, and obtains the first equipment operation strategy corresponding to the current power grid area from the abnormal analysis network, and the first equipment operation strategy includes the maintenance parameters for each power equipment in abnormal operation;

[0026] The analysis report to be supervised records the equipment information of all power equipment in the power grid area. Each power equipment is equipped with an operation supervision node. The real-time power load of the power equipment during operation is obtained through the operation supervision node. All operation supervision nodes in the same power grid area are integrated to build a supervision network for the corresponding power grid area. The second equipment operation strategy corresponding to the power grid area is derived from the supervision network. The second equipment operation strategy records the total real-time power load of all power equipment in each power grid area. The trend of power load status change in the power grid area is judged by the total real-time power load.

[0027] Furthermore, a corresponding device control set is constructed according to the power equipment operation strategy corresponding to each power grid area, and the process of remotely controlling the corresponding power equipment in each power grid area under the clustered microgrid area through the device control set includes:

[0028] The device control set includes a device fault processing set and a device supervision processing set;

[0029] When the power equipment operation strategy corresponding to the power grid area is the first equipment operation strategy, an equipment fault processing set is constructed for the current power grid area, and the equipment fault processing set records the execution steps of the corresponding maintenance parameters of the abnormally operating power equipment;

[0030] When the power equipment operation strategy corresponding to the power grid area is the second equipment operation strategy, an equipment supervision processing set is constructed for the current power grid area, and the equipment supervision processing set includes a total power load threshold and an execution step of active power distribution scheduling for each power equipment;

[0031] Through the equipment fault processing set, all abnormally operating power equipment in the power grid area that is in a load overload state is remotely controlled, and then all abnormally operating power equipment is repaired to normal operation; for the power grid area in a suitable load state, if it is judged that the power load state of the power grid area has a trend of change, the power equipment in the current power grid area is remotely controlled through the equipment supervision processing set, so as to keep the total real-time power load of the power grid area in a suitable load state; if it is judged that the power load state of the power grid area has no trend of change, no operation is performed.

[0037] The decision module is used to perform data analysis based on the power grid operation log report of each power grid area, and then decide on the power equipment operation strategy corresponding to each power grid area;

[0038] The control execution module is used to construct a corresponding device control set according to the power equipment operation strategy corresponding to each power grid area, and remotely control the corresponding power equipment in each power grid area under the clustered microgrid area through the device control set.

[0039] It should be further explained that, in the specific implementation process, the process of establishing power collection nodes in each grid area within the clustered microgrid and integrating all power collection nodes to build a power data collection network includes:

[0040] The clustered microgrid is divided into several grid areas, and the grid areas are numbered and recorded as i, then i = 1, 2, 3, ..., n, where n is a natural number greater than 0. Starting from number i = 1, the value of i is increased by 1 each time, and each grid area is traversed in turn to establish the power collection node corresponding to each grid area;

[0041] Set up a terminal network, and each power collection node in the power grid area submits a network access application to the terminal network. The network access application submitted by each power collection node carries the regional information of its own power grid area. The terminal network reviews the network access application. When the review is passed, the network computing power corresponding to the current terminal network is allocated to the power collection node that submitted the network access application.

[0042] If the audit fails, no action will be taken;

[0043] A communication path is built between every two adjacent power collection nodes, and then a communication path is built between any two adjacent power collection nodes. All power collection nodes are integrated through the communication path, and then a power data collection network is built.

[0044] It should be further explained that, in the specific implementation process, the process of collecting the power data set corresponding to the entire cluster microgrid through the power data collection network includes:

[0045] Locate the power equipment in the grid area that is in operation under the current cluster microgrid, and dispatch the power collection nodes corresponding to the grid area in the power data collection network, and obtain the power operation data corresponding to the current grid area through the power collection nodes;

[0046] The power operation data includes the operation time, operation voltage, operation power and operation current corresponding to each power device in the power grid area, locates the power devices corresponding to the power grid area that is not in operation under the clustered microgrid, and sets the power collection nodes corresponding to the power grid area in the power data collection network to a silent state;

[0047] It should be noted that when the power collection node is in a silent state, the power collection node does not enable the network computing power obtained from the terminal network, which reduces the network load of the current power data collection network to a certain extent.

[0048] The power operation data corresponding to each grid area is integrated as the power data set corresponding to the entire cluster microgrid, and the power data set is sent to the load forecasting module.

[0049] It should be further explained that, in the specific implementation process, the process of predicting the power load status of each grid area included in the clustered microgrid according to the power data set and generating a grid operation log report corresponding to each grid area includes:

[0050] The power data set records power operation data corresponding to each power grid area, and obtains the regional operation coefficient corresponding to the power grid area through the power operation data of each power grid area, and the regional operation coefficient of the i-th power grid area is recorded as τ[i], and the value of τ[i] includes 0 and 1;

[0053] When T 运行 ≤T 阈值 , V 运行 ≤V 阈值 , W 运行 ≤W 阈值 and A 运行 ≤A 阈值 When at least one of the above is not true, the regional operation coefficient τ[i] of the current power grid area is taken as 0;

[0054] The power load status of the power grid area includes a suitable load status and a load overload status;

[0055] When the regional operation coefficient τ[i] corresponding to the power grid area = 0, the power load state of the corresponding power grid area is a load overload state;

[0056] When the regional operation coefficient τ[i] corresponding to the power grid area = 1, the power load state of the corresponding power grid area is a suitable load state;

[0057] A blank report file is bound to each power grid area, a monitoring period is set, and all power operation data of each power grid area during the monitoring period is entered into the corresponding bound blank report file, thereby generating a power grid operation log report corresponding to each power grid area.

[0058] It should be further explained that, in the specific implementation process, the process of transmitting the power grid operation log report to the decision optimization module through the internal communication network includes:

The security protection program retrieves the several security response instructions corresponding to the current external attack information, and then handles the external attack information through the security handling steps corresponding to all the security response instructions;

[0061] The power grid operation log is processed to remove external attack information, and an internal access code is bound to the power grid operation log. After the internal communication link obtains the internal access code, the power grid operation log is transmitted to the decision optimization module through the internal communication link;

[0062] If not, an internal access code is directly bound to the power grid operation log, and the power grid operation log carrying the internal access code is transmitted through the corresponding internal communication link.

[0063] It should be further explained that, in the specific implementation process, the process of conducting data analysis based on the grid operation log report of each grid area and then deciding the corresponding power equipment operation strategy for each grid area includes:

[0066] Construct an abnormal analysis network and a supervision network, and then decide on the corresponding first and second strategies for equipment operation respectively: the abnormal report to be analyzed records the equipment information corresponding to each power equipment in abnormal operation in the power grid area, set an abnormal analysis node for each abnormally operating power equipment, and enter the equipment information of each power equipment into the respective abnormal analysis nodes;

[0067] Integrate all abnormal analysis nodes in the same power grid area, and then construct an abnormal analysis network for the corresponding power grid area. The abnormal analysis network derives the first equipment operation strategy corresponding to the current power grid area. The first equipment operation strategy includes maintenance parameters for each power equipment in abnormal operation.

The second equipment operation strategy corresponding to the power grid area is derived from the supervision network. The second equipment operation strategy records the total real-time power load of all power equipment in each power grid area, and the trend of power load status change in the corresponding power grid area is judged by the total real-time power load.

[0069] It should be further explained that, in the specific implementation process, a corresponding device control set is constructed according to the power equipment operation strategy corresponding to each power grid area, and the process of remotely controlling the corresponding power equipment in each power grid area under the clustered microgrid area through the device control set includes:

[0073] The total power load threshold is used to determine whether there is a trend of change in the power load state of the power grid area. Specifically, when the total real-time power load of all power equipment in the power grid area is greater than the total power load threshold, it is determined that there is a trend of change in the power load state; otherwise, there is no trend of change.

[0074] Through the equipment fault processing set, all abnormally operating power equipment in the power grid area that is in a load overload state is remotely controlled, and then all abnormally operating power equipment is repaired to normal operation; for the power grid area in a suitable load state, if it is judged that the power load state of the power grid area has a trend of change, the power equipment in the current power grid area is remotely controlled through the equipment supervision processing set, so as to keep the total real-time power load of the power grid area in a suitable load state; if it is judged that the power load state of the power grid area has no trend of change, no operation is performed.
