Description

Technical Field

[0001] The present invention relates to the field of power distribution network troubleshooting, and in particular to a power distribution network regional agent power restoration method and device, a power distribution network feeder agent power transfer method and device, a power distribution network fault recovery device, and a computer-readable storage medium. Background Art

[0002] Fault recovery of distribution network refers to restorative reconstruction when permanent fault occurs in distribution network, and its purpose is to restore more fault loads at a faster speed. Fault recovery is of great significance to the power quality and power supply service of distribution network. Distribution network fault recovery strategies are generally divided into centralized and distributed. Centralized control strategies are generally mathematical optimization methods, heuristic search methods, and artificial intelligence algorithms. These algorithms calculate the optimal recovery plan based on global information, and the implementation principle is relatively simple. However, as the scale of distribution network expands and the amount of algorithm calculation increases, the timeliness of recovery gradually cannot meet the requirements. In addition, a single recovery decision center will also reduce the reliability of the system. Multi-agent system has the characteristics of distributed intelligence, and it has been widely used in active distribution network fault recovery.

[0003] However, the existing multi-agent fault recovery methods for distribution networks are all based on fiber optic channels. A large number of optical fibers need to be configured in the distribution network. Due to cost issues, multi-agent-based recovery solutions are difficult to promote on a large scale.

[0062] First, a brief introduction is given to the multi-agent system architecture of the distribution network. The multi-agent system architecture is set up in two layers. The upper agent is called the feeder agent (FA), which is set at the outlet of the substation feeder. It stores the network topology of the feeder, can monitor the operation data of the lower agent, and plays a coordinating role in the conflict of the lower agent. The lower agent is called the region agent (RA), which is set at the contact switch of the feeder. All regional agents communicate with other regional agents through 5G communication channels, and feeder agents communicate through intra-station or inter-station optical fiber channels. Regional agents are specifically marked according to the power supply conditions and the distribution of distributed power sources in the region.

[0063] 1) If the power supply in this region is normal, the region agent is marked as a normal region agent (NRA);

[0064] 2) If the region is out of power but there are VF (frequency voltage) controlled distributed power sources in the region, the regional agent is marked as a Micro-Grid Region Agent (MRA);

[0065] 3) If the power is off in this area and there is no VF (frequency voltage) controlled distributed power source in the area, the regional agent is marked as a non-transfer region agent (NTRA);

[0066] Its structural diagram is as follows Figure 1 As shown, the regional agent detects the electrical information in the area in real time and updates its own tag. When the system is not faulty, all regional agents are normal regional agents. After the system fails, the regional agent detects the change of electrical information (voltage, frequency) in the area and updates its own tag. Agents with different tags use different execution logic in recovery.

[0067] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0068] The core of the present invention is to provide a method for restoring power supply by a regional agent of a distribution network, and a flowchart of a specific implementation method thereof is shown as follows: Figure 2 As shown, it is called specific implementation mode 1, including:

[0069] S101: Determine the regional agent of the adjacent feeder.

[0070] This specific implementation method starts from the perspective of the regional agent to be transferred whose power supply has been cut off, and first determines the regional agents of adjacent feeders, that is, the regional agents directly connected to the regional agent to be transferred and belonging to other feeder agents. Of course, these regional agents of adjacent feeders should all be regional agents in normal power supply status.

[0071] S102: Sending a transfer request to a corresponding feeder agent through the regional agent.

[0072] The "corresponding feeder agent" in this step refers to the feeder agent to which each of the regional agents adjacent to the regional agent to be transferred belongs.

[0073] S103: Receive feeder constraint information sent by the feeder agent through the 5G channel.

[0074] After receiving the transfer request sent in the previous step, the feeder agent can obtain the initiator of the action, that is, the network address information of the agent in the area to be transferred, based on the transfer request. Then, the feedback feeder constraint information can be directly sent to the agent in the area to be transferred through the 5G channel without the need for backtransmission through the adjacent area agent, thus eliminating a step of transfer.

[0075] S104: Determine a target feeder agent according to the feeder constraint information.

[0076] S105: Sending dedicated supply confirmation information to the target feeder agent and accepting the transfer.

[0077] After the target feeder agent receives the dedicated supply confirmation information in this step, it is equivalent to that the target feeder agent and the regional agent to be transferred complete the handshake, and the regional agent to be transferred has been transferred to the feeder of the target feeder agent for management.

[0078] Of course, due to the complexity of the power distribution network, there is a situation where an agent in the area to be transferred can obtain power supply through multiple feeder agents at the same time. In this case, it is necessary to select the most suitable one from the multiple feeder agents. The specific steps are:

[0079] When there are multiple feeder agents, the receiving feeder constraint information sent by the feeder agent through the 5G channel includes:

[0080] Receive feeder constraint information sent by multiple feeder agents through the 5G channel.

[0081] Accordingly, determining the target feeder according to the feeder constraint information includes:

[0082] Determining the transfer balance degree corresponding to each feeder agent according to the plurality of feeder constraint information;

[0083] The feeder agent with the largest transfer balance is determined as the target feeder.

[0084] The definition of the feeder constraint information can be found in 6) below. The power transfer capabilities of different feeder agents are determined by different feeder constraint information, and the feeder agent with the strongest power transfer capability is selected as the target feeder to improve the overall stability of the distribution network.

[0085] The following is a brief description of the indicators and criteria in the distribution network fault recovery process:

[0086] 1) Feeder branch current constraints;

[0087] In order to ensure that the current of each branch in the feeder does not exceed the limit after the transfer, the feeder branch current constraint I cF for:

[0088]

[0089] D represents the collection of all branches under the feeder controlled by the feeder agent. max.j and I j They respectively represent the maximum allowable current passing through the line of branch j and the current flowing through it before transfer.

[0090] 2) Feeder node voltage constraints;

[0091] Define the path impedance Z m-n is the sum of the impedances on the line from node m to node n.

[0092]

[0093] L is the path with the smallest impedance between nodes m and n.

[0094] In order to ensure that the voltage at each point in the normal area of ​​the feeder does not exceed the limit after the transfer, the feeder node voltage constraint is expressed in the form of current.

[0095] I vb =(V b -V min.b ) / Z F-b (3)

[0096] Node b is the point with the lowest node voltage in the normal area under the feeder, V b is the voltage of node b before the transfer, V min.b is the minimum allowable voltage at node b, Z F-b It is the path impedance from the outlet terminal F of the transfer feeder to the node b.

[0097] 3) Voltage constraints in the area to be transferred;

[0098] In order to ensure that the node voltage in the area to be transferred does not exceed the limit after the transfer, the voltage constraint in the area to be transferred is expressed in the form of current:

[0099] I vf =(V h -V min.h ) / Z F-f (4)

[0100] Node f is the node in the area to be transferred, node h is the voltage in the adjacent normal area, V h is the voltage of node h before the transfer, V min.h is the minimum allowable voltage at node h, Z F-f It is the path impedance from the feeder outlet terminal F to the node f.

[0101] 4) Feeder transfer surplus;

[0102] Feeder transfer surplus describes the transfer capacity that the feeder can provide, which is mainly subject to the feeder branch current constraint and feeder node voltage constraint, expressed as:

[0103] S fe =U N ×min(I cF ,I vb ) (5)

[0104] U N is the nominal value of the node voltage.

[0105] 5) Microgrid power transfer surplus;

[0106] The distributed power sources in the distribution network are divided into two types: one is using V F Controllable distributed power sources are controlled to constant voltage and frequency at the grid access point, which can support the microgrid independently. The other is uncontrollable distributed power sources controlled by PQ and PV, which cannot operate independently in the microgrid and must follow the reference voltage and frequency provided by the outside world. Controllable distributed power sources are generally energy storage devices, diesel engines, etc., and uncontrollable distributed power sources are generally wind power generation, photovoltaic power generation equipment, etc.

[0107] The transfer capacity that the microgrid regional agent can provide to the outside is expressed by the microgrid transfer surplus as follows:

[0108]

[0109] D is the microgrid regional agent control area, S c is the controllable distributed power capacity, S nc is the capacity of uncontrollable distributed power generation, S L For load capacity.

[0110] 6) Balance of supply to be transferred;

[0111] Considering that the area to be transferred may receive transfers from microgrid regional agents and feeder agents, the balance degree of the transfer is defined as:

[0112]

[0113] The judgment conditions are:

[0114]

[0115] When C RA When ≥0, it is considered that external supply can restore all loads in the area and the supply is accepted; otherwise, it is considered that external supply cannot meet all local load demands and the supply is rejected.

[0116] 7) Regional load priority;

[0117]

[0118] D is the scope of regional agency control, S j and w j are the load capacity and importance quantified values ​​of node j respectively. The load importance is divided into three levels: important load, normal load, and shelvable load. j Corresponding to different values.

[0119] When the distribution network is operating normally, all regional agent marks are normal regional agents. After the distribution network has a permanent fault and is cut off, the downstream area of ​​the fault area loses power supply and becomes a power-off area. The regional agent marks in the power-off area change to regional agents to be transferred and microgrid regional agents.

[0120] When restoration is just underway, all the tie switches in the power-off area are disconnected. Different agents execute different restoration logics according to the following settings.

[0121] 1) Regional agent to be transferred;

[0122] The regional agent to be transferred may accept transfer information from the feeder agent and the microgrid regional agent, and give priority to the transfer information of the feeder agent for restoration.

[0123] 1. Carry out feeder agent transfer process;

[0124] 1a. The regional agent to be transferred does not store topology information and cannot communicate directly with non-superior feeder agents. It first sends its own regional load priority M to the surrounding normal regional agents. cu And transfer the transfer application containing its own IP information.

[0125] 1b. Receive feeder constraint related information (including feeder transfer surplus S) sent back from the feeder agent fe, the voltage of the normal node adjacent to the regional agent to be transferred and the path impedance between this point and the feeder outlet), calculate the balance degree C of the power to be transferred RA If the recovery conditions are met, a transfer consent command is sent to the feeder agent, the section switch is closed, the transfer from the feeder is received, the power supply in this area is restored, and its own identity is updated to a normal area agent, and in the next stage, it assists the surrounding area agents to be transferred to restore. If the recovery conditions are not met, a transfer refusal command is sent to the feeder agent, and the mark of the area agent to be transferred is maintained.

[0126] 2. Carry out the microgrid regional agent transfer process;

[0127] 2a. If no information is received from the feeder agent within a certain period of time, and the microgrid aggregation request and microgrid transfer surplus S sent by the microgrid regional agent are received, MG , calculate the transfer balance C RA If the recovery conditions are met, send the microgrid aggregation command and regional load priority M to the microgrid regional agent. cu .

[0128] 2b. Receive the start aggregation command sent by the microgrid agent, close the section switch, receive the transfer from the microgrid regional agent, complete the power supply restoration in this area, keep itself marked as the regional agent to be transferred, and wait for further transfer from the feeder agent.

[0129] 2)Normal regional agent;

[0130] Receive the regional load priority MCU and transfer application sent by the regional agent to be transferred, and forward the message information to its own superior feeder agent.

[0131] 3) Microgrid regional agent;

[0132] 1. Actively send microgrid aggregation requests and microgrid transfer surplus S to the surrounding area agents to be transferred MG .

[0133] 2. If multiple microgrid aggregation consent commands are received, the regional agent with the largest regional load priority Mcu to be transferred will be selected to reply with the microgrid aggregation start command.

[0134] 4) Feeder agent;

[0135] 1. The feeder agent receives multiple regional load priorities M forwarded from normal regional agents. cu After the transfer request, select the regional load priority M cu The largest regional agent to be transferred will send feeder constraint related information to the corresponding regional agent to be transferred according to the IP address in the transfer application.

[0136] 2. If a transfer agreement is received from the regional agent to be transferred, the regional agent will be included in its own feeder and controlled; if a transfer refusal order is received from the regional agent to be transferred, the C RA The lower supply-to-transfer area agent replies with information related to feeder constraints.

[0137] The power supply restoration method of the distribution network regional agent provided by the present invention includes determining the regional agent of the adjacent feeder; sending a transfer request to the corresponding feeder agent through the regional agent; receiving the feeder constraint information sent by the feeder agent through the 5G channel; determining the target feeder agent according to the feeder constraint information; sending a dedicated supply confirmation message to the target feeder agent, and accepting the transfer. In the prior art, due to the limitation of the laying of optical fiber, the lower-level agents (regional agents) and upper-level agents (feeder agents) between different substations (different feeders) cannot communicate directly, and information needs to be transferred bidirectionally through one or more agents. At each stage of restoring power supply, the number of communications between agents is increased, and the communication volume increases, the overall recovery process becomes complicated, and the fault tolerance rate is reduced. The present invention directly replaces the optical fiber with the 5G communication channel, and utilizes the characteristic of 5G communication that end-to-end transmission can be carried out through the network address. Only one one-way transfer is required during the recovery process. When the agent in the area to be transferred receives the feeder constraint information, direct communication with the feeder agent can be achieved, which significantly reduces the number of communications, thereby shortening the recovery time, reducing the communication volume, and avoiding the laying of a large number of optical fibers, which significantly reduces the cost.

[0138] A specific embodiment is provided below as a simulation verification:

[0139] Build a 70-node 4-feeder distribution network to verify the restoration strategy. The network topology is as follows Figure 3 As shown, 250kW photovoltaic power generation equipment is connected at nodes 13, 27, and 40 respectively. The photovoltaic equipment adopts the PQ control method and is considered to be an uncontrollable distributed power source. A 150kW micro gas turbine equipment is connected at node 61. The unit adopts the VF control method and is considered to be a controllable distributed power source. In the figure, s represents a circuit breaker or a contact switch, L represents a load, PV represents a photovoltaic power generation equipment, and GT represents a gas turbine. Because the fault recovery process takes a short time, it is considered that the output of the distributed power source is stable and the node load remains unchanged. Set the values ​​corresponding to important loads, normal loads, and shelvable loads to 100, 50, and 25 respectively.

[0140] A permanent fault occurs at feeder F4. Regional agents RA1~RA10 are all downstream of the fault. Each regional agent detects changes in voltage and frequency within the region and determines whether it is in the power outage area. RA7 detects that there are controllable distributed power sources in the region, which meets the microgrid operation conditions, and marks itself as a microgrid regional agent. There are no distributed power sources in the RA1~RA6, RA8~RA10 regions, and they mark themselves as regional agents to be transferred.

[0141] The end-to-end communication delay of the 5G communication channel is 12ms. The closing delay of the segment switch is 30ms. The message uses the improved R-GOOSE and R-SV messages that can be used for 5G communication channel transmission, which occupy 114 bytes and 253 bytes respectively.

[0142] In the first stage, NTRA10 sends a transfer request and regional load priority M to its respective superior feeder agents FA1 and FA2 via NRA11 and NRA12. cu , NTRA9 and NTRA4 send transfer requests and regional load priority M to FA2 and FA3 via NRA13 and NRA14 respectively. cu FA1 and FA3 only receive the only transfer request and return the feeder-related constraint information to NTRA10 and NTRA4 respectively. FA2 receives two transfer requests, compares the regional load priorities of the two applications, and sends the feeder constraint-related information to NTRA10 with the higher regional load priority. NTRA4 receives the return information from FA3 and calculates the balance degree C to be transferred. RA It determines that the transfer can be accepted, sends a transfer acceptance request to FA3, and closes s4. After receiving the two constraint information, NTRA10 selects C RA The larger FA1 sends a transfer approval instruction to FA1 and a transfer rejection instruction to FA2, closing s12. FA2 receives the transfer rejection instruction from NTRA10 and replies to RA9 with information related to feeder constraints. RA9 accepts the transfer and closes s10. MRA7 sends an aggregation application and microgrid transfer surplus S to NTRA8 and NTRA6 MG , NTRA8 and NTRA6 determine the C of MRA7 RA All of them can meet the transfer requirements, and send the approval aggregation application and regional load priority M to MRA7. cu , MRA7 selects NTRA6 with higher regional load priority for transfer and closes switch s7. The recovery process is as follows Figure 4 (The marking of regional agents is omitted in the figure).

[0143] In the second stage, NTRA8 receives the feeder constraint related information returned from FA1 and FA2 and selects the balance degree C to be transferred. RAThe larger FA2 obtains the transfer and closes switch s9. NTRA3 obtains the transfer from FA3 and closes switch s3. MRA7 and NTRA6 form a microgrid, whose microgrid transfer surplus is insufficient, and the microgrid aggregation process is stopped. In the third stage, NRA7 obtains the transfer from FA2 and closes switch s8. NTRA2 obtains the transfer from FA3 and closes switch s2. In the fourth stage, NTRA5 obtains the transfer from FA3 and closes switch s5. NTRA1 receives the transfer refusal instruction from FA3. In the fifth stage, NTRA1 obtains the transfer from FA3 and closes switch s1.

[0144] After the restoration, all power outage areas were restored to power, and the total network loss was 237.6kW. The voltage of each node after restoration was as follows: Figure 5-a , Figure 5-b , Figure 5-c , the minimum is 0.9156pu, which meets the constraints of voltage and current, verifying the effectiveness of this method. The time consumption and communication volume of each recovery stage are shown in Table 1.

[0145] Table 1 Switching actions, traffic volume and time consumption in each stage of the new recovery process under 5G

[0146]

[0147] It can be found that under the same network topology and the same fault location, if the optical fiber communication channel is used, the regional agent cannot directly communicate with the feeder agent that is not directly superior. The regional agent to be transferred needs at least one normal regional agent as a relay in the whole process of obtaining the communication transferred by the feeder agent that is not directly superior. The first stage of the recovery process is as follows Figure 6 The fiber end-to-end delay is set to 2ms, and GOOSE and SV messages are used, with the capacity of 76 and 169 bytes respectively. The time consumption and communication volume of each recovery stage are shown in Table 2.

[0148] Table 2 Switching actions, communication volume and time consumption at each stage in the recovery process of fiber optic situation

[0149]

[0150] If the recovery solution under optical fiber is directly used in 5G communication channel, the recovery process is exactly the same as the recovery solution under optical fiber, and only differs from optical fiber recovery in time consumption and communication volume. Figure 6 The time consumption and communication volume of each recovery stage are shown in Table 3.

[0151] Table 3 Switching actions, communication volume and time consumption at each stage of the recovery process in the case of 5G

[0152]

[0153] The three methods are compared in Table 4.

[0154] Table 4 Comparison of the effects of different recovery methods

[0155]

[0156] The original multi-agent fault recovery method is limited by the laying of optical fiber. The lower-level agents (regional agents) and upper-level agents (feeder agents) between different substations cannot communicate directly. Information needs to be transferred in both directions through one or more agents (the regional agent to be transferred sends messages to the feeder agent and the feeder agent sends messages to the regional agent to be transferred). At each stage of recovery, the number of communications between agents increases, and the communication volume increases, making the overall recovery process complicated and reducing the fault tolerance rate. If the original recovery method based on fiber channel is directly used for 5G communication channels, the shortcomings of 5G communication, such as high latency and sensitivity to communication volume, will be magnified, which will increase both the recovery time and the overall communication volume.

[0157] By adopting multi-agent fault recovery technology suitable for 5G communication and utilizing the characteristic of 5G communication that end-to-end transmission can be carried out through IP, the IP address of the agent in the area to be transferred is directly attached to the message. Only one one-way transfer is required during the recovery process (the agent in the area to be transferred sends a message to the feeder agent). When the agent in the area to be transferred receives the information, it can communicate directly with the feeder agent, significantly reducing the number of communications, thereby reducing the impact of the high latency of the 5G channel on the timeliness of recovery. Under the same recovery effect, it has lower recovery time and communication volume.

[0158] The following is an introduction to the distribution network regional agent power supply restoration device provided in an embodiment of the present invention. The distribution network regional agent power supply restoration device described below and the distribution network regional agent power supply restoration method described above can be referenced to each other.

[0159] Figure 7 The structural block diagram of the power supply restoration device for the distribution network area agent provided in the embodiment of the present invention is referred to as the specific implementation mode 2, and the reference Figure 7 The distribution network regional agent power restoration device may include:

[0160] An adjacent confirmation module 110 is used to determine the regional agent of the adjacent feeder;

[0161] A request sending module 120, configured to send a transfer request to a corresponding feeder agent via the regional agent;

[0162] The 5G communication module 130 is used to receive the feeder constraint information sent by the feeder agent through the 5G channel;

[0163] A feeder determination module 140, configured to determine a target feeder agent according to the feeder constraint information;

[0164] The first handshake module 150 is used to send dedicated supply confirmation information to the target feeder agent and accept the transfer.

[0165] As a preferred implementation, when there are multiple feeder agents, the 5G communication module 130 includes:

[0166] A plurality of receiving units, configured to receive feeder constraint information sent by a plurality of feeder agents through a 5G channel;

[0167] Accordingly, the feeder determination module 140 includes:

[0168] A transfer determination unit, configured to determine a transfer balance degree corresponding to each feeder agent according to a plurality of feeder constraint information;

[0169] The target feeder determining unit is used to determine the feeder agent with the largest transfer balance as the target feeder.

[0170] The power supply restoration device for the regional agent of the distribution network provided by the present invention includes an adjacent confirmation module 110 for determining the regional agent of the adjacent feeder; a request sending module 120 for sending a transfer request to the corresponding feeder agent through the regional agent; a 5G communication module 130 for receiving the feeder constraint information sent by the feeder agent through the 5G channel; a feeder determination module 140 for determining the target feeder agent according to the feeder constraint information; and a first handshake module 150 for sending a dedicated confirmation information to the target feeder agent and accepting the transfer. The present invention directly replaces the optical fiber with a 5G communication channel, and utilizes the characteristic of end-to-end transmission through the network address in 5G communication. Only one one-way transfer is required during the recovery process. When the regional agent to be transferred receives the feeder constraint information, direct communication with the feeder agent can be achieved, which significantly reduces the number of communications, thereby shortening the recovery time, reducing the communication volume, and avoiding the laying of a large number of optical fibers, which significantly reduces the cost.

[0171] The distribution network area agent power supply restoration device of this embodiment is used to implement the aforementioned distribution network area agent power supply restoration method. Therefore, the specific implementation method of the distribution network area agent power supply restoration device can be seen in the implementation method part of the distribution network area agent power supply restoration method in the previous text. For example, the adjacent confirmation module 110, the request sending module 120, the 5G communication module 130, the feeder determination module 140, and the first handshake module 150 are respectively used to implement steps S101, S102, S103, S104 and S105 in the above-mentioned distribution network area agent power supply restoration method. Therefore, its specific implementation method can refer to the description of the corresponding each part of the implementation method, which will not be repeated here.

[0172] The core of the present invention is to provide a method for power distribution network feeder agent transfer, a flowchart of a specific implementation method thereof is shown as follows: Figure 8 As shown, it is called specific implementation method three, including:

[0173] S301: Receive a transfer request.

[0174] As mentioned above, the transfer request is sent from the regional agent to be transferred through the regional agent of the adjacent feeder, that is, it is sent from the regional agent adjacent to the regional agent to be transferred on the feeder described by the execution subject of this method.

[0175] S302: Determine the network address of the regional agent to be transferred according to the transfer request.

[0176] S303: Send feeder constraint information to the agent in the area to be transferred through the 5G channel according to the network address.

[0177] S304: after receiving the dedicated supply confirmation information returned by the regional agent to be transferred, transferring the supply to the regional agent to be transferred.

[0178] As mentioned above, the dedicated confirmation information may not be returned through the 5G channel, but may be returned through the same channel as the transfer request. Of course, corresponding adjustments may be made based on actual conditions.

[0179] This specific implementation manner re-interprets the specific implementation manner one from the perspective of the feeder agent. Please refer to the specific implementation manner one in the previous text for details, and no further elaboration will be given here.

[0180] The distribution network feeder agent transfer method provided by the present invention includes receiving a transfer request; determining the network address of the regional agent to be transferred according to the transfer request; sending feeder constraint information to the regional agent to be transferred through the 5G channel according to the network address; and transferring to the regional agent to be transferred after receiving the dedicated supply confirmation information returned by the regional agent to be transferred. In the prior art, due to the limitation of laying optical fiber, the lower-level agents (regional agents) and upper-level agents (feeder agents) between different substations (different feeders) cannot communicate directly, and information needs to be transferred in both directions through one or more agents. At each stage of restoring power supply, the number of communications between agents is increased, and the communication volume is increased, the overall recovery process becomes complicated, and the fault tolerance rate is reduced. The present invention directly replaces the optical fiber with the 5G communication channel, and utilizes the characteristic of 5G communication that end-to-end transmission can be carried out through the network address. Only one one-way transfer is required during the recovery process. When the agent in the area to be transferred receives the feeder constraint information, direct communication with the feeder agent can be achieved, which significantly reduces the number of communications, thereby shortening the recovery time, reducing the communication volume, and avoiding the laying of a large number of optical fibers, which significantly reduces the cost.

[0181] On the basis of the third specific implementation mode, multiple transfer areas that issue transfer requests are further selected to obtain the fourth specific implementation mode, the flow chart of which is as follows: Fig. 9 As shown, including:

[0182] S401: receiving multiple transfer requests.

[0183] S402: Determine the network address of each regional agent to be transferred and the corresponding regional load priority according to the multiple transfer requests.

[0184] S403: Determine the regional agent to be transferred with the highest regional load priority as the target regional agent.

[0185] S404: Send feeder constraint information to the target area agent through the 5G channel according to the network address.

[0186] S405: After receiving the dedicated supply confirmation information returned by the regional agent to be transferred, transfer the supply to the regional agent to be transferred.

[0187] In this specific implementation, the situation in which multiple regional agents to be transferred make transfer requests to the same feeder agent is taken into consideration. At this time, the regional agents to be transferred are sorted according to their preset regional load priorities, and the one with the highest priority is selected for transfer. This can minimize the impact of distribution network failures and improve the working stability of the distribution network.

[0188] Further, in combination with the specific implementation mode 1 in the foregoing text, it can be known that there is a situation where multiple feeder agents provide feeder constraint information to the same regional agent to be transferred, and in this case, the regional agent to be transferred can only select one feeder agent for transfer, and the remaining feeder agents will not receive feedback. Therefore, after sending the feeder constraint information to the regional agent to be transferred through the 5G channel according to the network address, it also includes:

[0189] After the feeder constraint information is sent to the target regional agent, if the dedicated supply confirmation information is not received after the first preset time, the target regional agent is eliminated, and among the remaining regional agents, the regional agent to be transferred with the highest regional load priority is determined as the new target regional agent, and the feeder constraint information is sent to the new target regional agent.

[0190] The first preset time can be set according to actual conditions, but it shall be longer than the feedback time of the regional agent to be transferred under normal conditions. If the dedicated supply confirmation information is not received within the first preset time, it is determined that the regional agent to be transferred has selected other feeder agents. At this time, the feeder agent shall look for a new target regional agent among other regional agents to be transferred that have supply transfer needs. Of course, if the new target regional agent still does not respond after the first preset time, it shall be excluded and then continued to be searched among the remaining regional agents to be transferred until the regional agent to be transferred that gives feedback within the first preset time is found, or all regional agents to be transferred are excluded.

[0196] The second handshake module 240 is used to transfer the supply to the agent in the area to be transferred after receiving the dedicated supply confirmation information returned by the agent in the area to be transferred.

The present invention directly replaces the optical fiber with a 5G communication channel, and utilizes the characteristic of end-to-end transmission through a network address in 5G communication. Only one one-way transfer is required during the recovery process. When the agent in the area to be transferred receives the feeder constraint information, it can directly communicate with the feeder agent, significantly reducing the number of communications, thereby shortening the recovery time, reducing the communication volume, and avoiding the laying of a large number of optical fibers, significantly reducing the cost.
