Summary of the Invention

[0007] The purpose of this invention is to address some / all the shortcomings of existing technologies, particularly in the deep adaptation and adjustment of power generation, consumption, and auxiliary power sources in distribution networks. Through system-level control and optimization, it aims to achieve power supply and consumption protection and multi-level dynamic optimization of power supply and consumption. Therefore, a novel distribution network and its power supply and consumption coordination optimization system are proposed. The technical solution is as follows:

[0008] A novel power distribution network and its power supply and consumption coordination optimization system. This includes a coordination optimization system, a power supply coordination system, and a power consumption coordination system.

[0009] The coordination and optimization system is used to obtain the power generation power on the power generation side and the power consumption power on the power consumption side, and implement the wiring process based on the power generation and consumption balance configuration strategy: configuring power generation equipment, power supply main line, several power consumption main lines and corresponding power consumption clusters; the power supply main line is a power link configured with multiple power control units connected in series.

[0010] The coordinated optimization system is further configured as follows:

[0011] By comparing the power generation capacity on the power generation side with the power consumption capacity on the power consumption side, and by comparing the transmission capacity of the main power supply line with the total power consumption of the power consumption cluster under its jurisdiction, the total power generation capacity is determined to be insufficient or excessive, and the transmission capacity of the main power supply line is determined to be insufficient or excessive, and a power supply coordination instruction is issued to the power supply coordination system based on a preset priority.

[0012] Furthermore, by comparing the power transmission capacity of any main power line with the power consumption of the power supply cluster, it can determine whether the main power line has a power shortage or surplus; and based on this, it can issue a power coordination instruction to the power coordination system.

[0013] The power supply coordination system is equipped with a power supply control module for implementing power supply coordination procedures, including:

[0014] The auxiliary power supply on the main grid side connected to the main power supply line is controlled to perform power compensation or absorption in response to the power supply coordination command or the overcurrent risk of the main power supply line.

[0015] Overcurrent / short circuit interruption protection is implemented for any level power control unit, and after isolating the fault section, a new power transmission path is established to restore power supply by controlling the switching of the current flow direction inside the power control unit;

[0016] The electricity coordination system is equipped with an electricity control module for implementing electricity coordination procedures, including:

[0017] Control the distributed auxiliary power supply connected to the main power line, and in response to the power coordination command or the overcurrent risk of the main power line, perform power compensation or absorption; and implement overcurrent / short circuit interruption protection for the main power line.

[0018] The power supply coordination system and the power consumption coordination system are further configured to feed back their respective implementation results to the coordination optimization system, so that the system can implement wiring adjustment procedures accordingly.

[0019] As a preferred embodiment, the multi-level power control unit configured in series on the main power supply line includes a main line segment and a segment branch line connected in parallel. The two are connected in parallel and their first ends are connected to a dual-port SNOP for adjusting the current flow distribution in the two parallel lines.

[0020] The coordination optimization system is configured to include a coordination control module, which is connected to the power supply control module.

[0021] The power supply coordination system and the power supply coordination procedure implemented through the built-in power supply control module include:

[0022] Hardware configuration layer:

[0023] Multiple auxiliary power supplies on the main grid side are connected to the main line segment of the multi-level power control unit through a first SOP configured with a forward transmission mode and a reverse feed mode, respectively.

[0024] On the main line segment and the segment branch line, a first feeder terminal unit (FTU) is installed to implement overcurrent / short circuit interruption protection and to provide current and power data of the line in which it is located.

[0025] Control Implementation Layer:

[0026] When it is determined that there is an overcurrent risk in the main power supply line, or when a power supply coordination instruction is received from the coordination control module indicating a power shortage in the main power supply line or a power shortage in the total power generation on the generation side, the corresponding first SOP is controlled to work in reverse feed mode, so that the corresponding auxiliary power source on the main grid side releases electrical energy.

[0027] When it is determined that there is no overcurrent risk on the main power supply line, and a power supply coordination command is received from the coordination control module indicating that the main power supply line has excessive transmission power or the total power generation on the generation side has excessive power, the corresponding first SOP is controlled to operate in the forward transmission mode, so that the auxiliary power source on the main grid side can absorb electrical energy.

[0028] In a preferred embodiment, the power consumption control module is connected to the coordination control module, and the power consumption coordination system and the power supply coordination procedure implemented through the built-in power consumption control module include:

[0029] Hardware configuration layer:

[0030] Multiple distributed auxiliary power sources are connected to the main power line through a second SOP configured with a forward transmission mode and a reverse feed mode, respectively;

[0031] The main power line is equipped with a first feeder terminal unit (FTU) for implementing overcurrent / short circuit interruption protection and providing current and power data of the line in which it is located.

[0032] Control Implementation Layer:

[0033] When it is determined that there is an overcurrent risk in the main power line, or when a power coordination command indicating a power shortage in the main power line is received from the coordination control module, the corresponding second SOP is controlled to work in reverse feed mode, so that the corresponding distributed auxiliary power source releases electrical energy.

[0034] When it is determined that there is no overcurrent risk on the main power line and a power coordination command indicating that the main power line has excess power is received from the coordination control module, the corresponding second SOP is controlled to operate in the forward transmission mode, so that the distributed auxiliary power source can absorb electrical energy.

[0035] Furthermore, the power supply coordination system and the power consumption coordination system are configured to: based on the implementation results of the power supply coordination program and the power consumption coordination program, send them to the connected coordination optimization system, and implement a wiring adjustment program through the coordination control module, combining the implementation results and the corresponding received power consumption and power generation, including a power supply wiring adjustment program and a power consumption wiring adjustment program.

[0036] Power wiring adjustment procedure:

[0037] Within a preset time period, the results of the power supply coordination procedure include the first type of frequency of the first SOP reverse action triggered by overcurrent risk or the first SOP forward action triggered by excess power of the main power supply line / excess power of the generator side; and the second type of frequency of the first SOP reverse action triggered by a shortage of power of the main power supply line / shortage of power of the generator side.

[0038] If the first type of frequency result is significantly higher than the second type of frequency by exceeding a threshold, then an adjustment is made to reduce the number of power generation devices configured on the power generation side; otherwise, an adjustment is made to increase the number of power generation devices configured on the power generation side.

[0039] Electrical wiring adjustment procedure:

[0040] Within a preset time period, the results of the electricity coordination procedure implementation include the third type of frequency of the second SOP reverse action triggered by overcurrent risk or the second SOP forward action triggered by excessive power consumption; and the fourth type of frequency of the second SOP reverse action triggered by insufficient power consumption.

[0041] If the third type of frequency result exceeds the threshold by being higher than the fourth type of frequency, then the adjustment of increasing the electrical equipment configured on the power consumption side is implemented; otherwise, the adjustment of decreasing the electrical equipment configured on the power consumption side is implemented.

[0042] As an optional embodiment, the coordinated optimization system is further configured to execute a power deficit compensation strategy, including:

[0043] When the coordination and control module determines that there is a power shortage in a power consumption cluster, or that there is a shortage or surplus in the total power generation, or a shortage or surplus in the power transmission capacity of the main power supply line, and a compensation demand is generated, it performs coordination and control according to the following strategy:

[0044] When multiple compensation needs exist simultaneously, the first SOP is prioritized to operate in reverse feed mode, so that the auxiliary power supply on the main grid side releases power to perform global power compensation on the main power supply line.

[0045] When there is only a compensation requirement for a single power consumption cluster, or when there is still a compensation requirement for a power consumption cluster after the global power compensation is performed, the second SOP corresponding to the power consumption cluster is controlled to work in reverse feed mode, so that the distributed auxiliary power source releases power to perform local power compensation for the power consumption main line.

[0046] As an optional embodiment, the coordinated optimization system is further configured to implement a strategy for absorbing excess electricity, including:

[0047] When the coordination and control module determines that there is excess power in a power consumption cluster or excess power in the main power transmission line, and generates a demand for power absorption, it performs coordination and control according to the following strategy:

[0048] When multiple power absorption needs exist simultaneously, the first SOP is prioritized to operate in forward transmission mode, so that the auxiliary power source on the main grid side absorbs power and performs global power absorption on the main power supply line.

[0049] When there is only a single power consumption cluster's absorption demand, or when there is still a power consumption cluster's absorption demand after the global power absorption is executed, the second SOP corresponding to the power consumption cluster is controlled to operate in the forward transmission mode, so that the distributed auxiliary power source absorbs electrical energy and performs local power absorption for the power consumption main line.

[0050] As an optional embodiment, when the coordination control module executes the power supply wiring adjustment procedure, it is also simultaneously configured to execute the main grid-side auxiliary power supply adjustment procedure, including:

[0051] Based on the type and power regulation characteristics of the auxiliary power source on the main grid side, the priority order for its participation in power supply compensation and power consumption is set; and based on the statistical frequency of the power supply main line transmission power / total power generation power deficit or surplus on the generation side, and the real-time power monitoring data of the auxiliary power source on the main grid side, the position or capacity of the auxiliary power source on the main grid side connected to the main power supply main line bus is adjusted.

[0052] The real-time power monitoring data of the auxiliary power supply on the main grid side includes its discharge power when performing power supply compensation and its charging power when performing power supply absorption.

[0053] Furthermore, the multiple auxiliary power supplies on the main grid side are respectively connected to different segments of the main power supply line;

[0054] The coordination and control module sets the priority for the participation of the multiple main grid-side auxiliary power sources in power supply compensation and power absorption, including:

[0055] In response to an excess of power transmission capacity of the main power supply line / total power generation capacity on the generation side, the auxiliary power sources on the main grid side on the corresponding segments are activated in order from the generation side to the consumption side according to the main line segments to absorb the power.

[0056] In response to the power shortage of the main power transmission line / the total power generation on the generation side, the auxiliary power sources on the main grid side on the corresponding segments are activated in order from the power consumption side to the power generation side for power compensation according to the main line segments.

[0057] The main line segment locations where the multiple auxiliary power supplies on the main grid side are connected are configured based on their capacity characteristics and the statistical results of the first, second, third, and fourth frequency categories.

[0058] In a preferred embodiment, the coordination and optimization system is connected to the electricity consumption monitoring system and the energy management system to obtain the electricity consumption on the electricity application side and the power generation on the power generation side.

[0059] The electricity consumption monitoring system includes an electricity consumption information acquisition system and / or a power distribution management system;

[0060] The electricity consumption information collection system is used to monitor the first low-voltage electricity consumption cluster, which is mainly composed of residential users. Through the smart meters configured by each user and the data concentrators installed in the zone, the system automatically collects the electricity consumption data in the set area and sends it to the electricity consumption information collection system. After processing, the power consumption data of the first electricity consumption cluster is sent to the coordination and optimization system through the dedicated power communication network.

[0061] The power distribution management system is used to monitor the second power consumption cluster of high-voltage large users and / or the third power consumption cluster of medium and low voltage distribution networks. It collects the power consumption data of the second power consumption cluster by connecting to the high-voltage load management terminal or high-voltage smart meter through the power communication network, and / or collects the power consumption data of the third power consumption cluster by the feeder terminal unit (FTU) and distribution transformer terminal unit (TTU) installed at the distribution line switch and distribution transformer, and sends the data to the coordination and optimization system.

[0062] The energy management system is used to monitor the power generation of multiple and / or various types of power generation equipment centrally deployed on the power generation side, and to send the power generation data to the coordination and optimization system through the power communication network;

[0063] The coordination control module is configured as follows:

[0064] The power consumption data of the first power consumption cluster, the second power consumption cluster and / or the third power consumption cluster are analyzed and processed to obtain a first result including the characteristics of maximum power consumption and average power consumption.

[0065] The received power generation data is analyzed and processed to obtain a second result including the characteristics of maximum power generation and average power generation.

[0066] Record the daytime characteristics corresponding to each maximum power in the first and second results.

[0067] Furthermore, the power generation and consumption balance configuration strategy configured by the coordination control module includes:

[0068] Within a preset multi-day period, the power consumption monitoring results and the power generation monitoring results are matched and analyzed to derive a configuration strategy that balances power generation and power consumption, and the wiring processing procedure is generated and implemented accordingly.

[0069] The configuration strategy includes: adjusting the grid connection combination of the multiple and / or various power generation devices, and configuring or adjusting the power main line connected to the power supply main line for each power consumption cluster, so as to achieve a balanced configuration of the second result and the first result.

[0070] In a preferred embodiment, in the series power link, any group of main line segments and segment branches, whose parallel first end is connected to a dual-port SNOP, is connected to the upstream common distribution bus through a common input terminal, connected to the downstream main line segment through a first output port, and connected to the downstream segment branch through a second output port;

[0071] The ends of the downstream main line segment and the segment branch line are connected in parallel to the next level common distribution bus. The next level common distribution bus is used to connect to the common input terminal of the next level dual-port SNOP, or the common input terminal of multiple power supply main lines.

[0072] The power supply control module is configured as follows:

[0073] After the first feeder terminal unit (FTU) implements overcurrent / short-circuit interruption protection on the downstream main line segment of the fault, it acquires the corresponding interruption protection data and determines the fault location, and then blocks the first output port of the dual-port SNOP to isolate the faulty section.

[0074] After confirming the locked status of the first output port and the electrical isolation of the faulty section, the safety status of the new power transmission feeder to be put into operation, including the segmented branch line, is verified. After the verification is passed, the second output port is controlled to start, and power supply to the non-faulty area is restored through the new power transmission feeder.

[0075] As an optional embodiment, the distribution network is further configured to:

[0076] The power generation side is configured with multiple sub-power supply main lines, and each of the multiple sub-power supply main lines is configured as follows: correspondingly configured with several power consumption main lines and supplying power to several power consumption clusters, forming several sub-distribution networks, and configured with corresponding several sub-coordination optimization systems, sub-power supply coordination systems and sub-power consumption coordination systems;

[0077] Each of the sub-distribution networks and sub-coordination optimization systems is configured with all the technical features corresponding to any of the aforementioned distribution networks and coordination optimization systems according to the above-described invention.

[0078] The coordination and optimization system is also configured to perform inter-system coordination and optimization control on each of the sub-power supply coordination system and the sub-power consumption coordination system;

[0079] The coordination and optimization system, through each sub-coordination and optimization system, issues coordination and control commands to the sub-power supply coordination system and sub-power consumption coordination system within each sub-distribution network.

[0080] The present invention has the following beneficial effects:

[0081] This invention discloses a novel power distribution network and its power supply and consumption coordination optimization system. Based on precise adaptation of multiple power generation devices and multiple power consumption clusters, and the construction and adjustment of the power distribution network topology, the power supply and consumption coordination optimization system implements power supply and consumption coordination optimization and adaptive power allocation. The power supply coordination system implements various coordination, optimization, and adjustments of power generation equipment on the generation side and auxiliary power sources on the main grid side. The power consumption coordination system implements various coordination, optimization, and adjustments of power consumption clusters and equipment on the consumption side and distributed auxiliary power sources. This improves the efficiency of power shortage and surplus adjustment and the adaptive allocation effect. Through overcurrent / short-circuit interruption protection of the main power supply line and the main power consumption line, the continuous and robust operation of the power distribution network is achieved. This results in higher economic benefits from a novel power distribution network and its corresponding power supply and consumption coordination optimization system, improves the "source-load" synergy benefits, and allows for further dynamic adjustment optimization. Specifically, it also includes the following points:

[0082] 1. By coordinating and optimizing historical data analysis of power characteristics on both the generation and consumption sides, the system executes a source-load matching planning wiring procedure to adapt power generation equipment with different characteristics to power consumption clusters, and generates and implements the initial wiring procedure accordingly. This changes the rigid topology of the traditional distribution network, which "remains unchanged in the face of all changes," and constructs initial power supply and consumption lines that are more matched to actual power characteristics, significantly improving the source-load adaptation effect and operational efficiency of the distribution network.

[0083] 2. Based on the established power supply and consumption lines, the power adjustment of the auxiliary power supply on the main power supply line and the distributed auxiliary power supply on the main consumption line, as well as the line fault protection and current flow regulation of the power link connected in series by multi-level power control units on the corresponding main power supply line and the line fault protection and current flow regulation on the main consumption line, have achieved the stable operation and adjustment effect of the distribution network.

[0084] 3. Based on the established power supply lines, the main power supply line is equipped with a power link protection system consisting of multi-level power control units connected in series. The system also optimizes the priority of auxiliary energy sources on the main grid side, the order of their calls, and their corresponding topology locations. Through wiring adjustment programs and auxiliary power supply adjustment programs, the system achieves efficient and intelligent / optimized adjustment of power supply shortages and surpluses. Furthermore, by setting the call order based on the cost and response characteristics of different auxiliary power sources, the system achieves cost-effective energy management, resulting in significant economic value.

[0085] 4. Based on the more efficient operation and dispatching of the distribution network and the greater economic benefits, multiple sub-distribution networks are configured under the distribution network to form a larger cluster. On this basis, the system natively supports cascading multiple sub-distribution networks and constructs a hierarchical control system of "upper-level central dispatch—lower-level sub-dispatcher—lower-level execution" through a top-level coordination and optimization system. This architecture can be smoothly extended to large-scale, multi-regional distribution network clusters, realizing power mutual assistance and collaborative optimization between systems, greatly expanding the application scenarios and large-scale economic value of this invention.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0092] Reference Figure 1-3 The present invention provides an embodiment intended to explain and describe in detail the content of the claims and related technical implementation methods of the present invention. It is understood that the existing known technical content that is not fully and thoroughly described is also applicable to supporting the implementation and effect of the technical solution of the present invention.

It includes a coordination optimization system 100, and a power supply coordination system 200 and a power consumption coordination system 300 connected to the coordination optimization system 100. The system realizes signal and data interaction and corresponding control through a coordination control module 101 connected to the power supply control module 201 and the power consumption control module 301, respectively.

[0094] The coordination and optimization system 100 is used to obtain the power generation power on the power generation side and the power consumption power on the power consumption side, including monitoring and obtaining the power through the interconnected energy management system 400 and power consumption monitoring system 500; and based on the power generation and consumption balance configuration strategy, implements the wiring process: configuring power generation equipment, power supply main line 210, several power consumption main lines 310 and corresponding power consumption clusters; the power supply main line 210 is a power link configured with multiple power control units 211 connected in series.

[0095] The wiring process specifically includes: configuring multiple and / or various types of power generation equipment to be connected to the starting end of the power generation side; configuring the main power supply line 210 and several power consumption main lines 310 connected at the end to transmit power to the corresponding several power consumption clusters; the starting ends of the multiple power consumption main lines 310 are connected to the end of the main power supply line 210.

[0096] The power generation equipment involves multiple types and corresponds to a certain number, including traditional baseload energy 402: thermal power and nuclear power, and green energy power generation equipment 401: photovoltaic power generation equipment, wind power generation equipment, and hydropower generation equipment. The multiple power generation equipment is deployed in a certain number of combinations based on the regional conditions, and a balanced power supply effect is achieved by combining the multiple power generation equipment.

[0097] The coordination control module 101 further determines a combination scheme of multiple and / or various power generation devices connected to the output terminal of the power generation side based on the total power generation of each power generation device on the power generation side, combined with the preset power supply reliability configuration requirements, and the comparative analysis of the power generation and power consumption.

[0098] The coordination optimization system 100 is further configured to:

[0099] By comparing the power generation capacity on the generation side with the power consumption capacity on the consumption side, and by comparing the transmission power of the main power supply line 210 with the total power consumption of the power consumption cluster under its jurisdiction, the system determines whether there is a power shortage or surplus, and whether there is a power shortage or surplus in the transmission power of the main power supply line 210. Based on a preset priority, the system issues a power supply coordination command to the power supply coordination system 200. The transmission power of the main power supply line 210 is monitored by the first feeder terminal FTU215 installed on the main line segment 2111 of the first-level power control unit 211 of the priority main power supply line 210, which provides the current and power data of the line in which it is located. The preset priority can be set in the coordination control module 101 according to the needs, which sets the first priority of the comparison between the transmission power of the main power supply line 210 and the power generation capacity on the generation side.

[0100] Furthermore, by comparing the transmission power of any main power line 310 with the power consumption of the power cluster it supplies, it can determine whether the main power line 310 has a power shortage or surplus; and based on this, it can issue a power coordination instruction to the power coordination system 300. The actual transmission power of the main power line 310 is monitored by the second feeder terminal FTU 313, which provides the current and power data of the line in which it is located.

[0101] Accordingly, the system issues power supply coordination instructions and power consumption coordination instructions to the power supply coordination system 200 and the power consumption coordination system 300, and implements power adjustment control of the main power supply line 210 through the multi-level power control unit 211 and multiple main power consumption lines 310.

[0102] The power supply coordination system 200 is equipped with a power supply control module 201, which is used to cooperate with and implement the power supply coordination procedure from the hardware configuration layer and the control implementation layer, respectively, including:

[0103] The main grid-side auxiliary power supply 214 controls the main power supply line 210 and, in response to the power supply coordination command or the overcurrent risk of the main power supply line 210, performs power compensation or absorption through the main grid-side auxiliary power supply 214.

[0104] Overcurrent / short circuit interruption protection is implemented for any level power control unit 211, and after isolating the fault section, a new safe power transmission path is established to restore power supply by controlling the current flow direction switching inside the power control unit 211.

[0105] The power consumption coordination system 300 is equipped with a power consumption control module 301, which is used to cooperate with and implement the power consumption coordination program from the hardware configuration layer and the control implementation layer, respectively, including:

[0107] The power supply coordination system 200 and the power consumption coordination system 300 are further configured to feed back their respective implementation results to the coordination optimization system 100, so that the system can implement a wiring adjustment procedure accordingly. It is understood that, based on the connection between the coordination control module 101 and the power supply control module 201 and the power consumption control module 301, the interactive transmission of relevant implementation results and data, signals and control commands involved in this invention can be implemented.

[0111] Hardware configuration layer:

[0112] Multiple main grid-side auxiliary power supplies 214 are connected to the main line segment 2111 of the multi-level power control unit 211 through a first SOP 213 configured to have a forward transmission mode and a reverse feed mode respectively; the main grid-side auxiliary power supplies 214 include multiple types, and optimized configuration and priority power adjustment are implemented through the main grid-side auxiliary power supply 214 adjustment program;

[0113] The main line segment 2111 and the branch line segment 2112 are equipped with a first feeder terminal FTU215, which is used to implement overcurrent / short circuit interruption protection and provide current and power data of the line in which it is located; the monitored current is received by the power supply control module 201 and the overcurrent risk is analyzed.

[0114] The power data includes the original current and voltage sampling values ​​uploaded by the first feeder terminal FTU215, which are converted into power by the power supply control module 201 or the coordination control module 101 based on the sampling values; or the first feeder terminal FTU215 completes the power calculation in its internal intelligent unit and directly uploads the calculated power value to the power supply control module 201.

[0115] Control Implementation Layer:

[0116] When it is determined that there is an overcurrent risk in the main power supply line 210, or when a power supply coordination command is received from the coordination control module 101 indicating a power shortage in the main power supply line 210 or a power shortage in the total power generation on the power generation side, the corresponding first SOP 213 is controlled to work in reverse feed mode, so that the corresponding auxiliary power supply 214 on the main grid side releases power.

[0117] When it is determined that there is no overcurrent risk in the main power supply line 210, and a power supply coordination command is received from the coordination control module 101 indicating that the main power supply line 210 has excessive transmission power or the total power generation on the power generation side has excessive power, the corresponding first SOP 213 is controlled to work in the forward transmission mode, so that the auxiliary power supply 214 on the main grid side absorbs electrical energy.

[0118] As a preferred embodiment, the detailed configuration of the power coordination system 300 is as follows:

[0119] The power supply coordination system 300 and the power supply coordination procedure implemented through the built-in power control module 301 include:

[0120] Hardware configuration layer:

[0121] Multiple distributed auxiliary power sources 312 are connected to the main power line 310 via a second SOP 311 configured to have a forward transmission mode and a reverse feed mode, respectively.

[0122] The main power line 310 is equipped with a second feeder terminal FTU313, which is used to implement overcurrent / short circuit interruption protection and monitor current, and provide current and power data of the line it is located in; the monitored current is received and analyzed by the power control module 301 for overcurrent risk.

[0123] The power data includes the original current and voltage sampling values ​​uploaded by the second feeder terminal FTU313, which are converted into power by the power control module 301 or the coordination control module 101 based on the sampling values; or the second feeder terminal FTU313 completes the power calculation in its internal intelligent unit and directly uploads the calculated power value to the power control module 301.

[0124] Control Implementation Layer:

[0125] When it is determined that there is an overcurrent risk in the main power line 310, or when a power coordination command indicating a power shortage in the main power line 310 is received from the coordination control module 101, the corresponding second SOP 311 is controlled to work in reverse feed mode, so that the corresponding distributed auxiliary power supply 312 releases electrical energy.

[0126] When it is determined that there is no overcurrent risk in the main power line 310, and a power coordination command indicating that the main power line 310 has excess power is received from the coordination control module 101, the corresponding second SOP311 is controlled to operate in the forward transmission mode, so that the distributed auxiliary power supply 312 absorbs electrical energy.

[0127] In a preferred embodiment, the overcurrent risk threshold range received and compared by the power supply control module 201 and the power consumption control module 301 is a preset current value range lower than the overcurrent protection setting, such as 85%-95% of the overcurrent protection setting. The overcurrent protection setting corresponding to the overcurrent risk threshold range is reasonably adjusted by the dynamic adjustment of the first and second feeder terminals FTU.

[0128] The SOP stands for Soft Open Point, a type of intelligent soft switch; the SNOP stands for Soft Normally Open Point, a type of intelligent soft normally open switch.

[0129] Each main power line 310 is configured to be connected in parallel to at least one distributed auxiliary power source 312, such as an energy storage device 3121 with a capacity smaller than that of the energy storage power station 2142. The power supply control module 201 is configured to control the second SOP 311 on the main power line 310 to operate in reverse feed mode and forward transmission mode, so that the corresponding distributed auxiliary power source 312 releases and absorbs electrical energy. Among them, the main grid-side auxiliary power source 214 and the distributed auxiliary power source 312 are connected to the beginning of the corresponding hierarchical power control unit 211 and the main power line 310, so as to realize the power compensation and power absorption of the regulated branch by connecting another "branch".

[0130] In a preferred embodiment, the power supply coordination system 200 and the power consumption coordination system 300 are further configured to: based on the implementation results of the power supply coordination program and the power consumption coordination program, send them to the connected coordination optimization system 100, and implement a wiring adjustment program through the coordination control module 101, combining the implementation results and the corresponding received power consumption and power generation, including a power supply wiring adjustment program and a power consumption wiring adjustment program.

[0131] Power wiring adjustment procedure:

[0132] Within the preset time period, the results of the power supply coordination procedure include the first type of frequency of the first SOP213 reverse action triggered by overcurrent risk or the first SOP213 forward action triggered by the power supply main line 210 transmission power excess / total power generation on the generation side excess; and the second type of frequency of the first SOP213 reverse action triggered by the total power generation deficit.

[0133] If the first type of frequency result is significantly higher than the second type of frequency by exceeding a threshold, then an adjustment is made to reduce the number of power generation devices configured on the power generation side; otherwise, an adjustment is made to increase the number of power generation devices configured on the power generation side.

[0134] The first type of frequency and the second type of frequency correspond to the implementation results of the power supply coordination procedure, respectively pointing to the power generation equipment having excessive / excessive power generation and insufficient power generation.

[0135] Electrical wiring adjustment procedure:

[0136] Within the preset time period, the results of the implementation of the power coordination procedure include the third type of frequency of the second SOP311 reverse action triggered by overcurrent risk or the second SOP311 forward action triggered by excessive power consumption; and the fourth type of frequency of the second SOP311 reverse action triggered by insufficient power consumption.

[0137] If the third type of frequency result exceeds the threshold by being higher than the fourth type of frequency, then the adjustment of increasing the electrical equipment configured on the power consumption side is implemented; otherwise, the adjustment of decreasing the electrical equipment configured on the power consumption side is implemented.

[0138] The third and fourth frequency categories correspond to the implementation results of the power supply coordination procedure; they respectively indicate that the power used by the power consumption cluster is relatively less than the power transmitted on the main power supply line 310, and the power transmitted on the main power supply line 310 is relatively insufficient compared to the power used by the power consumption cluster.

[0139] Furthermore, the coordinated optimization system 100 is also configured to execute a power deficit compensation strategy, including:

[0140] When the coordination control module 101 determines that there is a power shortage in the power consumption cluster, or determines that there is a shortage or surplus in the total power generation, or a shortage or surplus in the transmission power of the main power supply line 210, and generates a compensation demand, it performs coordination control according to the following strategy:

[0141] When multiple compensation needs exist simultaneously, the first SOP213 is prioritized to operate in reverse feed mode, so that the main grid auxiliary power supply 214 releases power to perform global power compensation on the main power supply line 210.

[0142] When there is only a compensation requirement for a single power consumption cluster, or when there is still a compensation requirement for a power consumption cluster after the global power compensation is performed, the second SOP311 corresponding to the power consumption cluster is controlled to operate in reverse feed mode, so that the distributed auxiliary power supply 312 releases electrical energy to perform local power compensation for the power consumption main line 310.

[0143] Furthermore, the coordinated optimization system 100 is also configured to execute a strategy for absorbing excess electricity, including:

[0144] When the coordination control module 101 determines that there is excess power in the power consumption cluster or excess power transmission in the main power supply line 210, and generates a demand for power absorption, it performs coordination control according to the following strategy:

[0145] When multiple power absorption needs exist simultaneously, the first SOP213 is prioritized to operate in forward transmission mode, so that the auxiliary power supply 214 on the main grid side absorbs power and performs global power absorption on the main power supply line 210.

[0146] When there is only a single power consumption cluster's absorption demand, or when there is still a power consumption cluster's absorption demand after the global power absorption is executed, the second SOP311 corresponding to the power consumption cluster is controlled to operate in the forward transmission mode, so that the distributed auxiliary power source 312 absorbs electrical energy and performs local power absorption on the power main line 310.

[0147] Generally speaking, the generation of multiple power consumption compensation demands usually corresponds to the generation of power supply compensation demands. After the power supply control module 201 implements power supply compensation through the coordination control module 101, it can also flexibly absorb the power surplus that may be generated by multiple power main lines 310, so as to achieve balance.

[0148] Similarly, the generation of multiple power consumption demands generally corresponds to the generation of power supply consumption demands. After the power supply control module 201 implements power supply consumption based on the coordination control module 101 controlling the coordination control module 101, it can also flexibly compensate for the power deficit that may be generated by multiple main power lines 310, so as to achieve balance.

[0149] The power surplus / deficit of the power consumption cluster and the main power supply line 210 is preferably compared with the actual power transmission power by using the power data of the respective lines provided by the second feeder terminal FTU313 and the first feeder terminal FTU215. The remaining power consumption and total power consumption are obtained by the power consumption monitoring system 500 and the specific included power consumption information acquisition system 510 and / or power distribution management system 520.

[0150] As an optional embodiment, when the coordination control module 101 executes the power supply wiring adjustment procedure, it is also simultaneously configured to execute the main grid-side auxiliary power supply 214 adjustment procedure, including:

[0151] Based on the type and power regulation characteristics of the main grid-side auxiliary power supply 214, its priority order for participating in power supply compensation and power consumption is set; and based on the statistical frequency of the power transmission power of the main power supply line 210 / the total power generation power of the power generation side being insufficient or excessive, and the real-time power monitoring data of the main grid-side auxiliary power supply 214, the position or capacity of the main grid-side auxiliary power supply 214 connected to the main power supply line 210 bus is adjusted.

[0152] The real-time power monitoring data of the main grid-side auxiliary power supply 214 includes its discharge power when performing power supply compensation and its charging power when performing power supply absorption.

[0153] Specifically, the multiple auxiliary power supplies 214 on the main grid side are respectively connected to different main line segments 2111 of the main power supply line 210;

[0154] The coordination control module 101 sets the priority of the multiple main grid-side auxiliary power supplies 214 in participating in power supply compensation and power supply absorption, including:

[0155] In response to the excess power transmission capacity of the main power supply line 210 / total power generation capacity on the generation side, the auxiliary power supply 214 on the main grid side on the corresponding segment is activated in order from the generation side to the power consumption side according to the sequence of the main line segment 2111;

[0156] In response to the power transmission power of the main power supply line 210 being less than the total power generation power of the power generation side, the auxiliary power supply 214 on the main grid side on the corresponding segment is activated in order from the power consumption side to the power generation side according to the main line segment 2111.

[0157] The location of the main line segment 2111 where the multiple main network auxiliary power supplies 214 are connected is configured based on their capacity characteristics and the statistical results of the first, second, third, and fourth frequency categories.

[0158] In a preferred embodiment, the main grid-side auxiliary power supply 214 includes an energy storage power station 2142, an external power grid 2141 different from the distribution network, other distribution networks, and all or part of the auxiliary power supply in the hydrogen power generation system; the main grid-side auxiliary power supply 214 is connected to the main line segment 2111 in the preferred order as follows: external power grid 2141, energy storage power station 2142, hydrogen power generation system, and other distribution networks, which are sequentially connected to the power control units 211 arranged from the power generation side to the power consumption side in the power link.

[0159] It is worth noting that: for different types of auxiliary power supply 214 on the main grid side, corresponding power monitoring units are configured to acquire real-time power monitoring data, including configurations in the following ways:

[0160] For energy storage power station 2142: its power monitoring unit is integrated into the energy management system 400 or the bidirectional converter controller of energy storage power station 2142. This unit collects the DC side voltage and current of the energy storage battery in real time through voltage / current transformers, or through the power sensor on the AC side of the bidirectional converter, calculates and uploads the real-time charging / discharging active power, reactive power and battery state of charge, and sends them to the coordination control module 101 through the power communication network.

[0161] For an external power grid 2141 that differs from this distribution network: its power monitoring unit is a bidirectional smart meter or multi-functional power meter installed at the common connection point of the grid connection. The meter is equipped with a high-precision voltage / current transformer, which monitors and calculates the active and reactive power exchanged with the external power grid 2141 in real time, and sends the power flow direction and values ​​to the coordination control module 101 through the power communication network.

[0162] For other distribution networks: their power monitoring units are configured in the interconnection SOP controller connecting the two distribution networks. Through power sensor groups installed on both sides of the tie line, the magnitude and direction of power exchange between the two distribution networks are monitored and calculated in real time, and the data is uploaded to the coordination control module 101 via the dedicated power communication network.

[0163] For hydrogen power generation systems: the power monitoring unit is a functional module of a distributed control system or a programmable logic controller. This module collects the power consumed during hydrogen production in the electrolyzer and the output power during fuel cell power generation in real time. The collected data is acquired through voltage / current sensors, calculated, and then transmitted to the coordination control module 101 via industrial Ethernet or power communication network.

[0164] In a preferred embodiment, the power supply control module 201 further performs the following logic in conjunction with the state of charge of the energy storage station 2142 for charging control:

[0165] When the built-in state of charge of the energy storage power station 2142 is lower than a preset high charge threshold, it is determined to be in a rechargeable state; when the state of charge has reached the preset high charge threshold or is fully loaded, it is determined to be in a non-rechargeable state. Based on the non-rechargeable state determination, even if there is excess power, the power supply control module 201 will no longer control the charging of the energy storage power station 2142, but will instead control other auxiliary power sources 214 on the main grid side, such as the external power grid 2141, to perform power consumption, so as to protect the health of the energy storage power station 2142 and extend its cycle life.

[0166] The energy storage power station 2142 has a built-in battery management system, which is configured to obtain the state of charge of the energy storage battery pack by real-time acquisition and calculation of state parameters such as voltage, current and temperature, and send the state of charge data to the power supply control module 201.

[0167] In a preferred embodiment, when the coordination control module 101 executes the power wiring adjustment procedure, it is also simultaneously configured to execute the distributed auxiliary power supply 312 adjustment procedure, including:

[0168] Based on the type and power regulation characteristics of the distributed auxiliary power supply 312, its priority order for participating in power consumption compensation and power consumption absorption is set; and based on the statistical frequency of power shortage or surplus of the power consumption cluster and the real-time power monitoring data of the distributed auxiliary power supply 312, the location or capacity of the distributed auxiliary power supply 312 connected to the main power line 310 is adjusted.

[0169] The real-time power monitoring data of the distributed auxiliary power supply 312 includes its discharge power when performing power compensation and its charging power when performing power consumption.

[0170] The distributed auxiliary power supply 312 configured in any of the main power lines 310 includes a plurality of (preferably multiple) distributed energy storage devices 3121, and optionally also includes electric vehicle charging facilities with charging and discharging functions, and is configured with their distributed access locations, input capacity, and corresponding priority order for participating in power compensation and power consumption.

[0171] For different types of distributed auxiliary power supplies 312, corresponding power monitoring units are configured to acquire real-time power monitoring data, and are configured in the following ways:

[0172] For the distributed energy storage device 3121: its power monitoring unit is integrated into the bidirectional converter controller or battery management system of the distributed energy storage device 3121. This unit collects the DC side voltage and current of the energy storage battery in real time through voltage / current sensors, or calculates and uploads real-time charging / discharging active power, battery state of charge and other data through the power sensor on the AC side of the bidirectional converter, and sends them to the corresponding power consumption control module 301 through the local communication network or power communication network, and then reports them to the coordination control module 101.

[0173] For electric vehicle charging facilities with charging and discharging functions: the power monitoring unit is a power metering chip and sampling circuit integrated into the charging pile controller or the vehicle-to-grid bidirectional charging module. This unit monitors the DC or AC voltage and current between the charging pile and the electric vehicle battery system in real time, accurately calculates and uploads the real-time charging power or the discharging power fed back to the grid, and sends the power data to the corresponding power control module 301 through the charging station management platform or direct communication module, which then reports it to the coordination control module 101.

[0174] In a preferred embodiment, the power control module 301 controls the distributed energy storage device 3121 by performing the following logic in conjunction with its state of charge:

[0175] When its state of charge (SBC) is below a preset threshold or not fully loaded, it is determined to be in a rechargeable state and can respond to power excess commands for charging and absorption. When its SBC reaches full load, it is determined to be in a non-rechargeable state and will no longer respond to charging commands. The distributed energy storage device 3121 has a built-in battery management system, which is configured to obtain the SBC by real-time acquisition and calculation of state parameters such as voltage, current, and temperature of the energy storage battery, and send the SBC data to the power consumption control module 301.

[0176] The power control module 301 receives real-time power data from each of its distributed auxiliary power sources 312 and reports it to the coordination control module 101. Based on this data, the coordination control module 101 summarizes the real-time status of the distributed auxiliary power sources 312 under each main power line 310, and, in conjunction with preset priority levels for each auxiliary power source, generates and dynamically adjusts power compensation or power consumption instructions for each distributed auxiliary power source 312, which are then issued and executed through the corresponding power control module 301.

[0177] In a preferred embodiment, the coordination and optimization system 100 is connected to the electricity monitoring system 500 and the energy management system 400 to obtain the electricity consumption on the electricity side and the power generation on the power generation side.

[0178] The electricity monitoring system 500 includes an electricity information acquisition system 510 and / or a power distribution management system 520.

[0179] The electricity consumption information collection system 510 is used to monitor the first low-voltage electricity consumption cluster 511, which is mainly composed of residential users. Through the smart meters configured by each user and the data concentrators installed in the zone, the electricity consumption data in the set area is automatically collected and sent to the electricity consumption information collection system 510. After processing, the power consumption data of the first electricity consumption cluster 511 is sent to the coordination and optimization system 100 through the dedicated power communication network, and is received by the coordination control module 101.

[0180] The power distribution management system 520 is used to monitor the second power consumption cluster 521 of high-voltage large users and / or the third power consumption cluster 522 of medium and low voltage power distribution networks. It collects the power consumption data of the second power consumption cluster 521 by connecting to the high-voltage load management terminal or high-voltage smart meter through the power communication network, and / or collects the power consumption data of the third power consumption cluster 522 by the feeder terminal unit (FTU) and distribution transformer terminal unit (TTU) installed at the power distribution line switch and distribution transformer, and sends the data to the coordination and optimization system 100, such as by receiving it through the coordination control module 101.

[0181] The energy management system 400 is used to monitor the power generation of multiple and / or various types of power generation equipment centrally deployed on the power generation side, and to send the power generation data to the coordination and optimization system 100 through the power communication network. Specifically, the energy management system 400 is configured to monitor the operating status and power output of each power generation equipment on the power generation side in real time, and send the data to the coordination and optimization system 100 to support it in performing power generation characteristic analysis and power supply and consumption balance decision-making.

[0182] Its monitoring network consists of the following hardware:

[0183] Current sensors, voltage sensors, and power transmitters deployed at the output ends of various power generation equipment (such as photovoltaic inverters, wind turbines, gas turbines, etc.) are used to measure the generation voltage and current in real time and calculate the active power and reactive power.

[0184] The remote terminal unit (RTU) configured at the power generation site is used to centrally access the monitoring data of all the above sensors and perform functions such as data preprocessing and protocol conversion.

[0185] The remote terminal unit (RTU) will process the data, including the real-time power generation, voltage, current, and operating status information related to the power generation process of each power generation device, and upload it to the coordination control module 101 of the coordination optimization system 100 through a dedicated power communication network for subsequent analysis and processing.

[0186] The coordination control module 101 is configured as follows:

[0187] The power consumption data of the first power consumption cluster 511, the second power consumption cluster 521 and / or the third power consumption cluster 522 are analyzed and processed to obtain a first result including the characteristics of maximum power consumption and average power consumption.

[0188] The received power generation data is analyzed and processed to obtain a second result including the characteristics of maximum power generation and average power generation.

[0189] Record the daytime time characteristics corresponding to each maximum power in the first and second results, such as by configuring the clock module through the coordination control module 101.

[0190] Furthermore, the power generation and consumption balance configuration strategy configured by the coordination control module 101 includes:

[0191] Within a preset multi-day period, the power consumption monitoring results and the power generation monitoring results are matched and analyzed to derive a configuration strategy that balances power generation and power consumption, and the wiring processing procedure is generated and implemented accordingly.

[0192] The configuration strategy includes: adjusting the grid connection combination of the multiple and / or various power generation devices, and configuring or adjusting the power main line 310 connected to the power supply main line 210 for each power consumption cluster, so as to achieve a balanced configuration of the second result and the first result.

[0193] In a preferred embodiment, the coordination control module 101 is also used to execute the following "source-load matching planning" procedure:

[0194] Within a preset number of multi-day periods (e.g., a typical week including workdays and rest days), the coordination control module 101 performs trend analysis on the acquired electricity consumption monitoring results and the power generation monitoring results, extracting the maximum / average power consumption of each electricity consumption cluster and its occurrence time, as well as the maximum / average power generation of each power generation device and its output time, which correspond to the first result and the second result.

[0195] Then, the coordination control module 101 associates and matches the above features, calculates and generates a static power supply and consumption configuration scheme that can maintain a stable power balance in the multiple multi-day periods, and applies it.

[0196] refer to Figure 3 In a preferred embodiment, for the main power supply line 210, in the corresponding series power link, any group of main line segments 2111 and segment branches 2112, whose parallel first end is connected to the dual-port SNOP 212, is connected to the upstream common distribution bus through the common input terminal 2123, connected to the downstream main line segment 2111 through the first output port 2121, and connected to the downstream segment branch 2112 through the second output port 2122;

[0197] The ends of the downstream main line segment 2111 and the segment branch line 2112 are connected in parallel to the next level common distribution bus. The next level common distribution bus is used to connect to the common input terminal 2123 of the next level dual-port SNOP212, or the common input terminal of multiple power supply main lines 310.

[0198] The power supply control module 201 is configured as follows:

[0199] After the first feeder terminal FTU215 implements overcurrent / short-circuit interruption protection for the faulty downstream main line segment 2111, it acquires the corresponding interruption protection data and determines the fault location, and then blocks the first output port 2121 of the dual-port SNOP212 to isolate the faulty segment.

[0200] After confirming the locked state of the first output port 2121 and the electrical isolation of the fault section, the safety status of the new power transmission feeder to be put into operation, including the segmented branch line 2112, is verified. After the verification is passed, the second output port 2122 is controlled to start, and the power supply to the non-fault area is restored through the new power transmission feeder.

[0201] As a preferred embodiment, the configuration settings specifically include:

[0202] In the fault detection and location section, the faulty main line segment 2111 is determined through the power supply control module 201:

[0203] The system receives the interruption implementation signal and fault-related information uploaded by the first feeder terminal FTU215 after implementing overcurrent / short circuit interruption protection. The fault-related information includes at least the direction of the fault current, and may also include the magnitude and nature of the fault current.

[0204] The power supply control module 201, based on the preset network topology and the installation location of the first feeder terminal FTU 215, makes a comprehensive judgment using a direction comparison method, a differential current comparison method, or a logic interlocking algorithm to determine the faulty main line segment 2111. Preferably, the first feeder terminal FTU 215 is installed at the starting end of each main line segment 2111 and segment branch line 2112.

[0205] The judgment logic of the direction comparison method is shown in the following example:

[0206] If a certain first feeder terminal FTU215 reports that a positive fault current is detected flowing from the beginning to the end of the power supply main line 210, then it is determined that the fault point is located downstream of the section where the FTU is located.

[0207] If both adjacent first feeder terminals FTU215 report an interruption implementation signal, and the upstream FTU reports a positive fault current while the downstream FTU reports a reverse fault current or does not detect a positive fault current that reaches its protection setting, then the fault point is determined to be located in the main line segment 2111 between the two adjacent FTUs.

[0208] If the first feeder terminal FTU215 that reports the interruption implementation signal is installed at the beginning or end of the main power supply line 210, then by combining this single FTU with the preset network topology, it can be determined whether the fault point is located at the beginning or end of the main line segment 2111.

[0209] In addition, it also includes a fault section isolation and confirmation section: after the power supply control module 201 determines the faulty main line section 2111, it executes the following isolation procedure:

[0210] The first port of the dual-port SNOP212 connected in parallel with the faulty main line segment 2111 is locked, and the port lock signal returned by the dual-port SNOP212 is received to confirm that the port is in a locked state.

[0211] By using the first feeder terminal FTU215 on either side or one side of the faulty main line segment 2111, it is confirmed that the voltage at its measurement point has dropped below the low-voltage threshold to confirm the electrical isolation result of the faulty segment. The specific confirmation method is as follows:

[0212] If the faulty main line segment 2111 is an intermediate segment, it is confirmed by the two first feeder terminals FTU215 on its upstream and downstream sides respectively;

[0213] If the faulty main line segment 2111 is a starting or ending segment, it is confirmed by a single first feeder terminal FTU215 on its downstream or upstream side.

[0214] It also includes a backup path verification and power restoration section: after the power supply control module 201 confirms that the faulty section has been electrically isolated, the following power restoration procedure is executed:

[0215] By querying the electrical measurement values ​​of the second port of the dual-port SNOP212 connected to the segment branch 2112 that is connected in parallel with the faulty main segment 2111, and combining this with a preset network topology model, the electrical connectivity and load-bearing capacity of the backup path are verified. The safety standards for verification include:

[0216] Based on the new topology formed by the segmented branch 2112, the calculated expected current is lower than the overcurrent protection setting.

[0217] The voltage difference between the second port of the dual-port SNOP212 and the side of the segmented branch 2112 to be connected satisfies the synchronization condition.

[0218] Subsequently, once the verification is passed and the new path formed by the segmented branch line 2112 is confirmed to be safe, the power supply control module 201 controls the dual-port SNOP 212 to start its second port, establish a new power transmission feeder through the segmented branch line 2112, and connect it to the downstream main line segment 2111 or the main power supply line 310 to restore power supply to the non-faulty area.

[0219] In a preferred embodiment, both the power supply control module 201 and the coordination control module 101 pre-store a complete power distribution network topology model. The model includes the installation location, connection relationship, and relative position information of all feeder terminals (FTUs), dual-port SNOPs (SNOPs) 212, and related equipment in the topology, such as whether the equipment is located at the beginning, end, or intermediate segment of the main power supply line 210.

[0220] In a preferred embodiment, the first feeder terminal unit (FTU215) is preferably installed at the starting end of each main line segment 2111 and segment branch line 2112 to monitor the current and power of its respective line in real time and upload the data to the power supply control module 201. The coordination control module 101 aggregates the measurement data of each first feeder terminal unit (FTU215) on the main power supply line 210 through the power supply control module 201 to determine the total transmission power of the main power supply line 210 and thereby determine whether there is a power shortage or excess.

[0221] The second feeder terminal FTU313 is preferably installed at the starting end of each main power line 310 to monitor the current and power of its respective main power line 310 in real time and upload the data to the power control module 301. The coordination control module 101 obtains the transmission power data of the main power line 310 through the power control module 301 and compares it with the power consumption data of the corresponding power cluster obtained from the power monitoring system 500 to determine whether the main power line 310 has a power shortage or surplus.

[0222] With the above configuration, the coordination control module 101 can achieve precise power status perception and coordinated control of the distribution network from global to local levels, based on the line-level precise power data provided by the first and second feeder terminals FTU313 and combined with the system-level power generation and consumption data obtained from the energy management system 400 and the power consumption monitoring system 500.

[0223] The installation positions of the first feeder terminal FTU215 and the second feeder terminal FTU313 are preferably set at the starting ends of the main line segment 2111 and the segment branch line 2112, and at the starting end of the main power supply line 310, respectively (the attached drawings are not drawn according to this standard).

[0224] In a preferred embodiment, the distribution network is further configured as follows:

[0225] The power generation side is configured with multiple sub-power supply main lines 210. Each of the multiple sub-power supply main lines 210 is configured as follows: correspondingly configured with several power consumption main lines 310 to supply power to several power consumption clusters and form several sub-distribution networks, and configured with several corresponding sub-coordination optimization systems, sub-power supply coordination systems and sub-power consumption coordination systems 300.

[0226] Each of the sub-distribution networks and sub-coordination optimization systems is configured with all the technical features of any of the aforementioned distribution networks and the coordination optimization system 100 in the above embodiments.

[0227] The coordination and optimization system 100 is further configured to: perform inter-system coordination and optimization control on each sub-power supply coordination system and sub-power consumption coordination system 300; including the coordination and optimization system 100 issuing coordination control commands to the sub-power supply coordination system and sub-power consumption coordination system 300 within each sub-distribution network through each sub-coordination and optimization system.

[0228] Specifically, the coordination and optimization system 100 manages the distribution network cluster composed of the multiple sub-distribution networks. This includes the following aspects:

[0229] Configuration of a single sub-distribution network:

[0230] Each sub-distribution network is an independent, fully functional power management unit; and has its own sub-generation side, which is composed of some of the generation equipment of the generation side, sub-power supply main line 210, sub-power consumption main line 310 and sub-power consumption cluster;

[0231] Each sub-distribution network is equipped with a complete three-level control system: sub-coordination and optimization system, sub-power supply coordination system and sub-power consumption coordination system 300; the sub-coordination and optimization system is independently responsible for monitoring the power generation and consumption within the sub-distribution network by connecting its sub-energy management system 400 and sub-power consumption monitoring system 500.

[0232] Coordinated control of multiple sub-distribution networks:

[0233] The top-level coordination and optimization system 100, through the sub-coordination and optimization systems of each sub-distribution network, achieves overall control of all sub-distribution networks, forming a hierarchical control system of "upper-level central dispatch - lower-level sub-distribution dispatch - lower-level execution". The interaction mode of control flow and data flow in this system is as follows:

[0234] The top-level coordination and optimization system 100 issues strategy instructions to each sub-coordination and optimization system;

[0235] After parsing the instructions, each sub-coordination and optimization system sends them to the sub-power supply control module and sub-power consumption control module 301 under its jurisdiction and control, and implements different actions of corresponding SOP and SNOP according to the specific scenario;

[0236] The real-time operation data and protection action results of each sub-distribution network are then aggregated and reported to the top-level coordination and optimization system 100 in the reverse order.

[0237] Interconnection between sub-distribution networks:

[0238] As another preferred implementation, power interconnection can be achieved between any two sub-distribution networks' sub-power supply main lines 210 through additionally configured interconnection SOPs and main line connection branches; the interconnection SOPs are similar to the first SOP 213 and the second SOP 311, and are similarly configured to have forward transmission mode and reverse feed mode.

[0239] When a sub-distribution network experiences excess power that it cannot absorb or a power deficit that it cannot compensate for, the top-level coordination optimization system 100 can issue instructions to the sub-coordination optimization systems of the relevant sub-distribution networks to control the interconnection SOP to operate in forward transmission or reverse feed-in mode, thereby realizing power support and mutual assistance between sub-distribution networks.

[0240] Working principle:

[0241] This invention proposes a power supply and consumption coordination optimization system based on a novel power distribution network. It aims to achieve deep collaboration and adaptive optimization across the "source-grid-load-storage" system through a three-tiered control architecture: a top-level coordination optimization system 100, an intermediate-level power supply / consumption coordination system 300, and bottom-level execution equipment. The corresponding working process is detailed in the following aspects / levels:

[0242] I. Initial Power Supply and Utilization Topology Construction (Source-Load Matching Planning):

[0243] The operation of the power distribution network and system begins with static planning: the coordinated optimization system 100, through the energy management system 400 and the electricity consumption monitoring system 500, acquires the power generation data of each power generation device on the generation side and the power consumption data of each power consumption cluster on the consumption side. The built-in coordinated control module 101 executes the "source-load matching planning" program, which matches the maximum / average power characteristics of power generation and consumption and their occurrence periods within (multiple) preset multi-day time periods, generating a basic configuration strategy that enables power generation and consumption to achieve power balance over a longer period.

[0244] Based on this strategy, the coordination control module 101 generates and executes the initial wiring processing program to complete the initial one-time topology construction of the distribution network. Specifically, this includes: determining the grid connection combination of each power generation device and configuring the main power consumption line 310 connected to the main power supply line 210 for each power consumption cluster, thereby building an optimized initial power supply and consumption line architecture.

[0245] II. Real-time Operation and Adaptive Adjustment (Dynamic Optimization Closed Loop):

[0246] During the real-time operation phase, the system implements corresponding dynamic optimization closed-loop. The power supply coordination system 200 and the power consumption coordination system 300 continuously execute their respective coordination procedures:

[0247] Power supply coordination procedure: Regulation is achieved through multi-level power control units 211 configured on the main power supply line 210. Each level of the power control unit 211 consists of a main line segment 2111 and a segmented branch line 2112 connected in parallel, with the first end of the parallel connection connected via a dual-port SNOP 212. The power supply control module 201 controls the SNOP to adjust the current flow distribution in the two parallel lines. Simultaneously, the auxiliary power supply 214 on the main grid side is distributed to each level of power control unit 211 via a first SOP 213 with bidirectional power control capability to achieve global power adjustment and support.

[0248] Power Coordination Procedure: Distributed auxiliary power supply 312 is connected in parallel to each main power supply line 310 through the second SOP311 to provide local power adjustment and support for the power consumption cluster.

[0249] During system operation, the FTU monitors the current in real time. When a local overcurrent risk or global power imbalance occurs, the coordination control module 101 controls the corresponding SOP to operate in reverse feed mode (compensating for deficits) or forward transmission mode (absorbing excess power) according to a preset strategy, thereby achieving real-time power balance and line protection.

[0250] All protection actions and power regulation events are recorded. After a preset period, the coordination control module 101 counts the frequency of various events, executes power supply and power consumption wiring adjustment procedures, dynamically adjusts the access configuration of power generation equipment and power consumption equipment, as well as the access location and capacity of the main grid side and distributed auxiliary power supply 312, so that the system topology is continuously optimized and improved to adapt to the long-term changes of power consumption clusters, power generation equipment, and auxiliary power supply.

[0251] III. Spatial Priority Control of Power Links:

[0252] The main power supply line 210 is constructed as a power link consisting of multiple power control units 211 connected in series. Based on this structure, the system is configured with a fine-grained spatial priority control strategy:

[0253] When the total power generation is excessive, the auxiliary power source 214 on the main grid side, which is close to the power generation end (i.e. the front end of the power link), is activated first to absorb the excess power, thereby implementing source interception and transmitting the corresponding absorption implementation step by step.

[0254] When the power consumption is insufficient, the auxiliary power supply 214 on the main grid side, which is close to the end of the power consumption side (i.e., the back end of the power link), is activated first to provide compensation, and the corresponding compensation is implemented step by step forward.

[0255] For different types of auxiliary power sources 214 on the main grid side, the system sets the call priority according to their power regulation characteristics. For example, when there is a surplus, it will be given priority to sell electricity to the external grid 2141 or to be absorbed by the large energy storage power station 2142. When there is a shortage, it will be given priority to be efficiently supplemented by other interconnected distribution networks. The hydrogen power generation system responds on demand, thereby achieving energy regulation and optimization with high economic efficiency and cost-effectiveness.

[0256] IV. Fault Isolation and Power Restoration:

[0257] When a permanent fault occurs in a main line segment 2111, the FTU on it first implements overcurrent / short-circuit interruption protection. After receiving the interruption signal, the power supply control module 201 accurately locates the faulty segment using algorithms such as the direction comparison method. It then blocks the corresponding port of the dual-port SNOP 212 for that segment to isolate the faulty section. After confirming electrical isolation, it verifies the safety of the parallel segment branch line 2112 path. Upon successful verification, it controls the SNOP to activate the backup port, establishing a new transmission feeder through the segment branch line 2112 to quickly restore power supply to the non-faulty area.

[0258] V. System-level linkage of multi-sub-distribution networks:

[0259] As an extended embodiment, the system supports large-scale clusters composed of multiple sub-distribution networks. Each sub-distribution network serves as a fully functional power management unit, equipped with a complete set of sub-coordination optimization systems, sub-supply coordination systems, and sub-consumption coordination systems 300. The top-level coordination optimization system 100, through the various sub-coordination optimization systems, forms a hierarchical control system of "upper-level overall dispatch—lower-level sub-dispatch—lower-level execution," achieving unified management of all sub-distribution networks. Furthermore, the sub-supply main lines 210 of each sub-distribution network can be connected via interconnection SOPs to achieve power mutual assistance and collaborative support between systems, meeting the power supply and consumption coordination optimization needs of larger-scale and more complex scenarios.

[0260] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
