Description

Technical Field

[0001] The present invention relates to a microgrid control system, and in particular to a microgrid control system based on new energy application and applied in the field of power supply or distribution system. Background Art

[0002] Micro-Grid refers to a small power system composed of distributed power sources, loads, power storage, power distribution and control systems. The micro-grid control system is a small power generation and distribution system composed of distributed power sources, power storage devices, energy conversion devices, related loads and monitoring and protection devices. When micro-grids are used in smart parks, the load energy consumption and the generation of new energy power have large fluctuations, which will cause instability in the operation of micro-grids.

[0003] In order to solve the problem of the volatility of park load energy consumption and the volatility of new energy electricity on the operation of microgrids, a microgrid control system in the market adopts the design of power storage technology and has a certain market share.

[0004] The specification of Chinese invention patent CN109980676B discloses a microgrid control system and a microgrid, wherein the microgrid control system includes: a grid-connected switch, an energy router, a first controller and a second controller, wherein the first controller controls the closing and opening of the grid-connected switch, and sends a first control instruction according to the state of the microgrid control system, and the second controller receives the first control instruction from the first controller, and controls the energy router in response to the first control instruction. The microgrid control system and the microgrid enhance the stability of the microgrid operation through hierarchical control; in addition, through dual closed-loop control of voltage and current, the ability to carry 100% unbalanced load in an off-grid state is achieved.

[0005] The specification of Chinese invention patent application CN119419827A discloses a microgrid adaptive load unloading method. The method comprehensively considers the power imbalance overload and low frequency risks. When the microgrid is in the grid-connected operation mode, it performs a preliminary evaluation and calculation of the power shortage in real time, and evaluates whether there will be an overload operation risk when the main grid fails and the microgrid switches to island operation. Based on this, the initial load unloading control is performed when the main grid fails; then, the time margin for the frequency to drop to the frequency threshold is estimated in real time according to the frequency change rate of the microgrid, and the risk level of the low frequency margin is judged, and the load is further unloaded accordingly. A microgrid control system is also disclosed. It can realize the frequency support function of the microgrid system under the island operation condition, avoid the microgrid protection shutdown caused by power imbalance and frequency drop, ensure the continuous power supply of important loads of the microgrid system, and try to meet the power supply requirements of the three-level loads, so as to improve the stability and power supply utilization of the microgrid.

[0006] Although the above-mentioned technology can stabilize the operation to a certain extent during the application of the microgrid, promote its power supply stability, and ensure its effectiveness in the application of smart parks. However, when the microgrid supplies power to the smart park, in order to balance the new energy power supply and load changes, energy storage devices will be used to store and level the power to further stabilize the operation of the microgrid. But during the process of using energy storage technology to store and level the power, the microgrid control system cannot effectively verify and judge the fault state of the energy storage device and its state of effectiveness in leveling power control. As a result, the originally effective power balance and energy storage management strategies cannot be normally implemented, which may also lead to a long-term power saturation state of the energy storage device, causing performance damage to the energy storage device and abnormal thermal runaway, thereby reducing the safety of the microgrid in the application of the smart park. Summary of the Invention

[0046] Figure 1 - Figure 9It is shown that a heat conduction bracket 31 is fixedly connected to the left end of the electricity storage state collection cylinder 3. The rear end of the heat conduction bracket 31 extends into the protection box 2 and is fixedly connected with a heat conduction insert 311. The heat conduction insert 311 abuts against the electricity storage device 1 and the electricity storage backup device 11 which are in corresponding cooperation with it. The front end of the heat conduction bracket 31 extends into the electricity storage state collection cylinder 3 and abuts against the heat conduction column 51. The cooperation of the heat conduction insert 311, the heat conduction bracket 31 and the heat conduction column 51 can conduct the heat generated by the electricity storage device 1 and the electricity storage backup device 11.

[0047] Figure 1 - Figure 9 It is shown that the self-heating state induction component 5 includes a heat conduction column 51 fixedly arranged on the left inner wall of the electricity storage state collection cylinder 3. The right end of the heat conduction column 51 is fixedly connected with a heat deformation spiral strip 52.

[0048] Figure 1 - Figure 9It is shown that the right end of the power storage state collection tube 3 is fixedly connected with a wire harness guide tube 32, the rear end of the wire harness guide tube 32 extends into the protective box 2, and the front end of the wire harness guide tube 32 extends into the power storage state collection tube 3 and cooperates with the discharge state sensing component 4. The wire harness guide tube 32 is provided with a wire harness electrically connected to the power storage device 1 and the power storage backup device 11 respectively corresponding to it. The front end of the wire harness is electrically connected to the induction electromagnetic block 41 through the wire harness guide tube 32. The wire harness guide tube 32 can protect and guide the wire harness, and realize the electrical connection between the power storage device 1 and the induction electromagnetic block 41 and the power storage backup device 11 and the induction electromagnetic block 41 through the wire harness, so that it can be passed Whether the induction electromagnetic block 41 generates electromagnetic effect, the discharge state of the power storage device 1 and the power storage backup device 11 is reacted, and the discharge state data of the power storage device 1 and the power storage backup device 11 are effectively collected, which is convenient for the subsequent real-time verification of the status of the power storage device 1 and the power storage backup device 11. In this way, when the power storage and power leveling are invalid, invalid data can be obtained in time to avoid the problem of continuous power saturation caused by long-term charging of the power storage device 1 and the power storage backup device 11, thereby reducing the performance damage of the power storage device 1 and the power storage backup device 11 during abnormalities and ensuring the application safety of the power storage device 1 and the power storage backup device 11.

[0049] Figure 1 - Figure 9 The discharge state sensing component 4 is shown to include an induction electromagnetic block 41 fixedly arranged on the right inner wall of the power storage state collection tube 3, a reset contraction spring 44 is fixedly connected to the left end of the induction electromagnetic block 41, a discharge contact 42 slidingly matched with the inner wall of the power storage state collection tube 3 is fixedly connected to the left end of the reset contraction spring 44, and the discharge contact 42 cooperates with the discharge trigger sheet 332, and a strong magnetic block matching with the induction electromagnetic block 41 is embedded at the right end of the discharge contact 42, and the input end of the discharge trigger collection module is connected to the discharge contact 42 signal, and the cooperation between the discharge trigger collection module and the discharge contact 42 can realize the effective monitoring of the discharge data of the power storage device 1 and the power storage backup device 11, and timely and real-time display of the status of the power storage device 1 and the power storage backup device 11 to the microgrid control processing unit, promote its regulation and guarantee function on the power storage device 1 and the power storage backup device 11, and reduce the performance damage of the power storage device 1 and the power storage backup device 11 caused by the discharge process.

[0050] Figure 1 and Figure 2 It is shown that the input end of the microgrid control processing unit is also connected to a new energy power collection unit, a power storage device power collection unit, a load data collection unit and a control instruction optimization unit, and the output end of the microgrid control processing unit is also connected to a load control unit, an on-grid and off-grid control unit and an emergency warning unit;

[0051] The input end of the new energy power collection unit is signal-connected to the new energy power end. The input ends of the power collection units of the electricity storage devices are respectively signal-connected to the electricity storage device 1 and the electricity storage backup device 11. The input end of the load data collection unit is signal-connected to the park load end. The input end of the regulation instruction optimization unit is signal-connected to the smart park control platform;

[0052] The output end of the load regulation unit is signal-connected to the park load end. The output end of the grid-connected and off-grid regulation unit is signal-connected to the intelligent power exchange cabinet. The intelligent power exchange cabinet is a structure in the prior art and is directly cited here without any changes to its structure and principle, so it will not be elaborated here. The output end of the emergency warning unit is signal-connected to the alarm installed on the smart park control platform. When the microgrid is applied to the smart park, the microgrid control system is installed on the smart park control platform. While realizing the power support and regulation in the smart park, improving the application efficiency of new energy power in the smart park, and ensuring the power stability of the smart park, it can also effectively display and interact the relevant data of its power management and regulation of the smart park through the smart park control platform, promoting the safety and effectiveness of power support and regulation.

[0053] Figure 1 - Figure 9 It shows that when the microgrid control system based on new energy application is applied in the smart park, the smart park control platform inputs relevant data such as the load data of the smart park, the load peak-valley period range, the meteorological data of the smart park area, the power supply status data of the power grid in the smart park area, the maximum charge-discharge cycle data of the electricity storage device 1 and the electricity storage backup device 11, and the electricity storage parameters of the electricity storage device 1 and the electricity storage backup device 11 into the microgrid control processing unit through the regulation instruction optimization unit. The microgrid control processing unit processes and applies the received data. At the same time, the new energy power collection unit collects the data of the new energy power end, converts it and transmits it to the microgrid control processing unit. The park load end transmits the real-time load data to the microgrid control processing unit through the load data collection unit. The microgrid control processing unit performs arithmetic analysis based on the acquired data. When it is judged that the new energy power can support the operation of the park load, the intelligent power exchange cabinet is controlled through the grid-connected and off-grid regulation unit to exchange and regulate the power circuit of the smart park, so that the new energy power end can provide power support for the load of the smart park. And when the microgrid control processing unit judges that there is still surplus new energy power after supporting the park load, the surplus power is stored in the electricity storage device 1 and the electricity storage backup device 11 through the electricity storage regulation unit. The power is preferentially stored in the electricity storage device 1, and the power data in the electricity storage device 1 and the electricity storage backup device 11 is transmitted to the microgrid control processing unit through the power collection unit of the electricity storage device. After the power storage in the electricity storage device 1 is saturated, the power is then transmitted to the electricity storage backup device 11 for storage.

[0054] When the new energy power collection unit transmits power data on the new energy power side to the microgrid control and processing unit, and transmits meteorological data on this area of the smart park through the regulation instruction optimization unit, and comprehensively judges that the power output from the new energy power side cannot support the application of the park load side or cannot support the application of the park load side during peak and valley periods, the microgrid control and processing unit controls the discharge of the energy storage device 1 and the energy storage backup device 11 through the energy storage regulation unit, preferentially releasing the electric energy stored in the energy storage device 1. After the electric energy stored in the energy storage backup device 11 is released, the electric energy stored in the energy storage backup device 11 is released again to support the application of the park load power, ensure the application stability of the park microgrid, and when all the power in the energy storage device 1 and the energy storage backup device 11 is released, if the microgrid control and processing unit determines according to the received data that the new energy power side still cannot generate power to support the operation of the park load, it controls the intelligent power exchange cabinet through the grid connection and disconnection regulation unit, enabling the microgrid in the park to be connected to the external power grid, providing power support for the park load through the external power grid, and at the same time controlling the energy storage device 1 and the energy storage backup device 11 to generate energy storage through the energy storage regulation unit, storing the electric energy generated by the new energy power side during this process, effectively promoting the full utilization of the electric energy of the new energy power side, while ensuring the stability and effectiveness of the power support in the smart park, it can also improve the efficiency of the smart park's application of new energy power and reduce the power cost of the smart park; when the microgrid control and processing unit determines according to the data transmitted by the new energy power collection unit and the regulation instruction optimization unit that the power generated by the new energy power side is insufficient to support the park load and the external power grid has a power outage, the microgrid control and processing unit not only controls the discharge of the energy storage device 1 and the energy storage backup device 11 in sequence through the energy storage regulation unit to support the park load, but also controls the park load through the load regulation unit, cutting off some non-essential loads to reduce the energy loss of the smart park, and also generates an emergency alarm signal through the emergency warning unit to remind the smart park maintenance personnel to make an emergency plan for this situation to reduce the losses and panic caused by subsequent power shortages.

[0055] During the continuous operation of the microgrid control processing unit, through the coordinated action among the new energy power terminal, energy storage device 1, energy storage backup device 11, and the external power grid, it effectively realizes the function of promoting the operation stability of power support in the smart park, and can also improve the efficiency of new energy power application and reduce the power cost of the smart park. During the subsequent continuous application, the heat conduction chip 311 can directly conduct the temperature of energy storage device 1 or energy storage backup device 11, and conduct it to the heat conduction column 51 through the heat conduction bracket 31, causing the heat deformation spiral strip 52 to absorb the heat of energy storage device 1 and energy storage backup device 11. After the temperature reaches the deformation temperature of the heat deformation spiral strip 52, the heat deformation spiral strip 52 will produce an elongation deformation, driving the heat contact block 53 to move to the right in the energy storage state collection cylinder 3, and causing the heat contact block 53 to abut against the trigger piece 331. At this time, the self-heat trigger collection module in the energy storage device state collection unit receives the trigger signal of the heat contact block 53 and transmits it to the energy storage device state dual processing module. After analyzing and processing the data, the energy storage device state dual processing module transmits an overheat signal about energy storage device 1 or energy storage backup device 11 to the microgrid control processing unit through the self-heat state output module. After receiving the trigger signal in the self-heat one-way direction, the microgrid control processing unit;

[0056] The microgrid control processing unit judges the state of the power data generated at the new energy power terminal at this time through the data transmitted by the new power source power collection unit, the energy storage device power collection unit, and the load data collection unit. When there is continuous power surplus at this time, and it is judged that energy storage device 1 or energy storage backup device 11 is in a power saturation state through the signal of the energy storage state of energy storage device 1 or energy storage backup device 11 transmitted by the energy storage device power collection unit, it is judged that there is an abnormal control execution in the energy storage regulation unit at this time, or there is an abnormal performance in energy storage device 1 and energy storage backup device 11;

[0057] Furthermore, the microgrid control and processing unit first issues control instructions to cut off the charging of the energy storage device 1 or the energy storage backup device 11 through the abnormal forced regulation unit and then discharge after waiting for a period of time, iterating the energy storage control generated by the energy storage regulation unit. Then, the microgrid control and processing unit analyzes and judges the data transmitted by the subsequent energy storage device power acquisition unit and the self-heating state output module. When it is obtained that the power states of the subsequent energy storage device 1 and the energy storage backup device 11 remain constant during charging cut-off or the power decreases after discharge, and the self-heating state output module stops transmitting the trigger signal, the microgrid control and processing unit determines that the performances of the energy storage device 1 and the energy storage backup device 11 are normal at this time, and there is an execution abnormality in the energy storage control unit. The microgrid control and processing unit replaces the task execution of the energy storage regulation unit through the abnormal forced regulation unit, and generates a maintenance alarm signal through the alarm by the emergency warning unit, reminding the maintenance personnel to maintain and repair the energy storage regulation unit in time and handle the abnormal situation in time; when it is obtained that the power states of the subsequent energy storage device 1 and the energy storage backup device 11 remain unchanged and the self-heating state output module continuously transmits the trigger signal, the microgrid control and processing unit determines that the performances of the energy storage device 1 and the energy storage backup device 11 are abnormal at this time, replaces the task execution of the energy storage regulation unit through the abnormal forced regulation unit, and generates a maintenance alarm signal through the alarm by the emergency warning unit, reminding the maintenance personnel to maintain and repair the energy storage device 1 and the energy storage backup device 11 in time and handle the abnormal situation in time, and regulates the temperature of the space where the energy storage device 1 and the energy storage backup device 11 are located to ensure safety during subsequent maintenance and avoid the danger caused by continuous heat accumulation;

[0058] The microgrid control and processing unit judges the state of the power data generated at the new energy power end at this time through the data transmitted by the new power source power acquisition unit, the energy storage device power acquisition unit and the load data acquisition unit. When there is continuous power surplus at this time, and the signal of the energy storage state of the energy storage device 1 or the energy storage backup device 11 transmitted by the energy storage device power acquisition unit determines that the energy storage device 1 or the energy storage backup device 11 is in a non-power saturation state, it is judged that there is an acquisition execution abnormality in the energy storage device power acquisition unit at this time, or there is a control execution abnormality in the energy storage regulation unit, or there is a performance abnormality in the energy storage device 1 and the energy storage backup device 11;

[0059] Furthermore, the microgrid control and processing unit first controls the energy storage regulation unit to stop the charging state of the energy storage device 1 and the energy storage backup device 11 or to control the discharging of the energy storage device 1 and the energy storage backup device 11. After the subsequent self-heating state output module no longer transmits a trigger signal to the microgrid control and processing unit, when the power state data transmitted by the energy storage device power acquisition unit changes little or not at all, the microgrid control and processing unit determines that the energy storage regulation unit and the energy storage device 1 and the energy storage backup device 11 are performing normally, and the energy storage device power acquisition unit is abnormal; after the subsequent self-heating state output module continuously transmits a trigger signal to the microgrid control and processing unit, the microgrid control and processing unit issues a control instruction to cut off the charging of the energy storage device 1 or the energy storage backup device 11 and discharge it after waiting for a period of time through the abnormal forced regulation unit, iterating the energy storage control generated by the energy storage regulation unit. After the subsequent self-heating state output module no longer transmits a trigger signal to the microgrid control and processing unit and the power state data transmitted by the energy storage device power acquisition unit changes little or not at all, the microgrid control and processing unit determines that both the energy storage regulation unit and the energy storage device power acquisition unit are abnormal at this time, and the energy storage performance of the energy storage device 1 and the energy storage backup device 11 is normal; after the subsequent abnormal forced regulation unit takes effect and the self-heating state output module still continuously transmits a trigger signal to the microgrid control and processing unit, the microgrid control and processing unit determines that the energy storage performance of the energy storage device 1 and the energy storage backup device 11 is abnormal; after the microgrid control and processing unit determines the abnormal factor, it replaces the task execution of the energy storage regulation unit through the abnormal forced regulation unit, and generates a maintenance alarm signal through the alarm by the emergency warning unit to remind the maintenance personnel to promptly maintain and repair the energy storage device 1 and the energy storage backup device 11, promptly handle the abnormal situation, and regulate the temperature of the space where the energy storage device 1 and the energy storage backup device 11 are located to ensure safety during the subsequent maintenance process and avoid the danger caused by continuous heat accumulation.

[0060] During the continuous operation of the microgrid control processing unit, through the coordinated action among the new energy power terminal, energy storage device 1, energy storage backup device 11, and the external power grid, it effectively realizes the function of promoting the operation stability of power support in the smart park, and can also improve the efficiency of new energy power application and reduce the power cost of the smart park. During subsequent continuous application, when energy storage device 1 and energy storage backup device 11 generate a discharging effect due to long-term power saturation, the wire bundle can conduct the released power to the induction electromagnetic block 41, causing the induction electromagnetic block 41 to generate magnetism that repels the strong magnet block embedded at the right end of the discharge contact block 42, prompting the discharge contact block 42 to move leftward within the heat conduction bracket 31 and making the discharge contact block 42 abut against the discharge trigger piece 332. At this time, the discharge trigger acquisition module in the energy storage device state acquisition unit receives the trigger signal of the discharge contact block 42 and transmits it to the energy storage device state dual-processing module. After analyzing and processing the data, the energy storage device state dual-processing module transmits a discharge signal regarding energy storage device 1 or energy storage backup device 11 to the microgrid control processing unit through the discharge state output module. After receiving the trigger signal of the discharge one-way, the microgrid control processing unit;

[0061] The microgrid control processing unit judges the state of the power data generated by the new energy power terminal at this time through the data transmitted by the new power source power acquisition unit, the energy storage device power acquisition unit, and the load data acquisition unit. When there is continuous power surplus at this time, and it is judged that energy storage device 1 or energy storage backup device 11 is in a power saturation state through the signal of the energy storage state of energy storage device 1 or energy storage backup device 11 transmitted by the energy storage device power acquisition unit, it is judged that there is an abnormal control execution in the energy storage regulation unit at this time, or there is a performance abnormality in energy storage device 1 and energy storage backup device 11;

[0062] The microgrid control processing unit judges the state of the power data generated by the new energy power terminal at this time through the data transmitted by the new power source power acquisition unit, the energy storage device power acquisition unit, and the load data acquisition unit. When there is continuous power surplus at this time, and it is judged that energy storage device 1 or energy storage backup device 11 is in a non-power saturation state through the signal of the energy storage state of energy storage device 1 or energy storage backup device 11 transmitted by the energy storage device power acquisition unit, it is judged that there is an abnormal acquisition execution in the energy storage device power acquisition unit at this time, or there is an abnormal control execution in the energy storage regulation unit, or there is a performance abnormality in energy storage device 1 and energy storage backup device 11;

[0063] When the microgrid control and processing unit triggers a one-way signal through the above self-heating method, with the cooperation of the abnormal forced regulation unit, it can identify and alert abnormal data. When a one-way abnormal trigger occurs, it can self-check and verify the abnormality, ensuring the stable operation of the microgrid and the effectiveness of power support in the smart park. At the same time, it can also improve the response and handling efficiency of maintenance personnel to abnormalities through early warning alerts, fully enhance the robustness of the microgrid control system, and promote the protection of the energy storage device 1 and the energy storage backup device 11, and enhance their effectiveness and safety in the microgrid.

[0064] During the continuous operation of the microgrid control and processing unit, through the coordinated action among the new energy power terminal, the energy storage device 1, the energy storage backup device 11, and the external power grid, it can effectively promote the stable operation of power support in the smart park, improve the efficiency of new energy power application, and reduce the power cost of the smart park. During subsequent continuous application, due to the temperature conduction of the heat conduction column 51, the thermal deformation spiral bar 52 undergoes elongation deformation. When the thermal contact block 53 abuts against the trigger piece 331, the induction electromagnetic block 41 generates a magnetic force that repels the strong magnetic block embedded at the right end of the discharge contact block 42 under the power conduction of the wire bundle, causing the discharge contact block 42 to abut against the discharge trigger piece 332. The discharge trigger acquisition module and the self-heating trigger acquisition module in the energy storage device status acquisition unit simultaneously transmit trigger signals to the energy storage device status dual-processing module, enabling the energy storage device status dual-processing module to transmit trigger signals of two-way abnormalities to the microgrid control and processing unit through the discharge status output module and the self-heating status output module. After receiving the trigger signals of two-way abnormalities, the microgrid control unit first determines whether the new energy power support is sufficient. When it determines that the new energy power is insufficient, it accesses the external power grid power through the combined grid connection and disconnection regulation unit and the intelligent power exchange cabinet, and then generates a high-level alarm signal through the emergency warning unit, prompting the maintenance personnel to check and maintain the energy storage device 1, the energy storage backup device 11, and each unit of the microgrid control system at this time, and controls the temperature in the spaces where the energy storage device 1 and the energy storage backup device 11 are located to ensure the temperature of the energy storage device 1 and the energy storage backup device 11 and avoid the danger caused by continuous overheating. When the new energy power is sufficient, it maintains the power support of the new energy power terminal, and then generates a high-level alarm signal through the emergency warning unit, prompting the maintenance personnel to check and maintain the energy storage device 1, the energy storage backup device 11, and each unit of the microgrid control system at this time, and controls the temperature in the spaces where the energy storage device 1 and the energy storage backup device 11 are located to ensure the temperature of the energy storage device 1 and the energy storage backup device 11 and avoid the danger caused by continuous overheating. Furthermore, through the form of two-way triggering, it can judge the abnormal states of the energy storage device 1 and the energy storage backup device 11, promoting the efficiency of abnormal detection and response, and effectively enhancing the intelligent level and functionality of the microgrid control system.

[0065] The second implementation mode:

[0066] Figure 1 - Figure 11 Show a microgrid control system based on new energy applications. Both the right end of the heat conduction column 51 and the left end of the heat contact block 53 are fixedly connected with an initial thermal deformation guide rod 54, and the thermal deformation spiral strip 52 is sleeved outside the initial thermal deformation guide rod 54. The input end of the energy storage device state dual-processing module is also connected with a self-heating initial state acquisition module. The input end of the self-heating initial state acquisition module is signal-connected to the initial thermal deformation guide rod 54. The cooperation of the self-heating initial state acquisition module and the initial thermal deformation guide rod 54 can more accurately feedback the state data of the energy storage device 1 and the energy storage backup device 11, further promoting the timeliness of state display, being able to perform imaging feedback on the states of the energy storage device 1 and the energy storage backup device 11 at the initial stage of an anomaly, further promoting the efficiency of early warning and warning, promoting the efficiency of response processing, and ensuring the safety during the subsequent continuous application of the energy storage device 1 and the energy storage backup device 11.

[0067] Figure 1 - Figure 11 Show that both the left end of the induction electromagnetic block 41 and the right end of the discharge contact block 42 are fixedly connected with an initial discharge guide rod 43, and the reset contraction spring 44 is sleeved outside the initial discharge guide rod 43. The input end of the energy storage device state dual-processing module is also connected with a discharge initial state acquisition module. The input end of the discharge initial state acquisition module is signal-connected to the initial discharge guide rod 43. The cooperation of the discharge initial state acquisition module and the initial discharge guide rod 43 can effectively promote the accuracy of the discharge data acquisition of the energy storage device 1 and the energy storage backup device 11, and further promote the accuracy of the instruction execution verification of the energy storage device 1 and the energy storage backup device 11, thereby reducing the performance damage of the energy storage device 1 and the energy storage backup device 11 and promoting the durability of the energy storage device 1 and the energy storage backup device 11; and the cooperation of the self-heating initial state acquisition module, the discharge initial state acquisition module, the self-heating trigger acquisition module and the discharge trigger acquisition module can effectively realize the multi-level display of anomalies and promote the effectiveness of anomaly processing.

[0068] Figure 1 - Figure 11It shows that during the continuous operation of the microgrid control processing unit, through the coordinated action among the new energy power terminal, energy storage device 1, energy storage backup device 11, and the external power grid, it can effectively promote the operation stability of power support in the smart park, improve the efficiency of new energy power application, and reduce the power cost of the smart park. During subsequent continuous application, the heat conduction chip 311 can directly conduct the temperature of energy storage device 1 or energy storage backup device 11, and conduct it to the heat conduction column 51 through the heat conduction bracket 31, causing the heat deformation spiral bar 52 to absorb the heat of energy storage device 1 and energy storage backup device 11. After the temperature reaches the deformation temperature of the heat deformation spiral bar 52, the heat deformation spiral bar 52 will generate an elongation deformation, driving the heat contact block 53 to move to the right inside the energy storage state collection cylinder 3. At this time, the two initial heat deformation guide rods 54 will separate, and the heat contact block 53 will not contact the trigger piece 331. The disconnection signal of the initial heat deformation guide rod 54 will be transmitted to the energy storage device state dual processing module through the self-heating initial state collection module, enabling the energy storage device state dual processing module to transmit a unidirectional self-heating initial abnormal signal to the microgrid control processing unit through the self-heating state output module;

[0069] Or when energy storage device 1 and energy storage backup device 11 generate a discharge effect due to long-term power saturation, the wire bundle can conduct the released power to the induction electromagnetic block 41, causing the induction electromagnetic block 41 to generate a magnetic force that repels the strong magnetic block embedded at the right end of the discharge contact block 42, prompting the discharge contact block 42 to move automatically to the left inside the heat conduction bracket 31, causing the two initial discharge guide rods 43 to separate, and the discharge contact block 42 will not contact the discharge trigger piece 332. The disconnection signal of the initial discharge guide rod 43 will be transmitted to the energy storage device state dual processing module through the discharge initial state collection module, enabling the energy storage device state dual processing module to transmit a unidirectional discharge initial abnormal signal to the microgrid control processing unit through the discharge state output module;

[0070] After receiving the unidirectional self-heating initial abnormal signal or the unidirectional discharge initial abnormal signal, the microgrid control processing unit, through the cooperation between the microgrid control processing unit and the abnormal forced regulation unit when dealing with the self-heating trigger unidirectional signal disclosed in the first implementation method, realizes the investigation and warning of abnormal data, and generates a first-level maintenance alarm signal through the alarm; thereby effectively improving the accuracy and effectiveness of the status monitoring of energy storage device 1 and energy storage backup device 11.

[0071] And when the microgrid control processing unit receives the discharge initial state trigger signal and the self-heating trigger signal, or when it receives the self-heating initial state trigger signal and the discharge trigger signal, or when it receives the discharge initial state trigger signal and the self-heating initial state trigger signal, through the cooperation between the microgrid control processing unit and the abnormal forced regulation unit for the self-heating trigger unidirectional signal disclosed in the first implementation manner, the investigation and warning of abnormal data are realized, and a secondary maintenance alarm signal is generated by the alarm, while promoting the operation stability of the microgrid, effectively ensuring the effectiveness of state monitoring and early warning level classification, and promoting the maintenance personnel to take appropriate and effective emergency measures.

[0072] Combined with the current actual requirements, the above implementation manner adopted in this application, the protection scope is not limited to this. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
