[0002] In the renewable energy grid-connected power generation system, generators are usually prepared to ensure continuous power supply to the load when the grid is out of power. Due to the uncertainty of grid power outages, it is difficult to predict the time when the generator will start, and the generator startup noise is very loud. Therefore, starting the generator manually is often time-consuming and labor-intensive, and the continuity of power supply to the grid-connected power generation system cannot be guaranteed.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0043] In conjunction with the accompanying drawings, the microgrid system 100, the control method of the microgrid system 100, the control device of the microgrid system 100, the electronic device and the readable storage medium provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0044] like Figure 1 As shown, the microgrid system 100 provided in the embodiment of the present application includes a generator 120 and a power distribution module 110 .

[0045] Among them, the generator 120 is a device that can generate electrical energy. The generator 120 can be a diesel generator 120. The diesel generator 120 generates mechanical energy by burning diesel, and then drives the power generation components of the generator 120 to convert the mechanical energy into electrical energy. The distribution module 110 is a module that can distribute the electrical energy transmitted in the microgrid system 100.

[0046] In this embodiment, the power distribution module 110 includes at least one power distribution cabinet 111, and the power distribution cabinet 111 is used to connect with the load 220 and the new energy power generation equipment.

[0047] The power distribution cabinet 111 is a device for distributing and controlling electric energy in the power distribution module 110 , and the power distribution cabinet 111 can be connected to the load 220 and the new energy power generation equipment.

[0048] The load 220 and the new energy power generation equipment can be set in the microgrid system 100 or outside the microgrid system 100. The load 220 is a device that consumes electric energy, and the new energy power generation equipment is a device that generates electric energy through renewable natural resources. The new energy power generation equipment can be solar photovoltaic power generation equipment, wind power generation equipment, hydropower generation equipment, etc.

[0049] In this embodiment, the power distribution cabinet 111 may be connected to the new energy power generation equipment through the inverter 210 , and the power distribution cabinet 111 may distribute the electric energy output by the new energy power generation equipment to the load 220 .

[0050] It is understandable that the microgrid system 100 can be connected to the power grid. When the power grid operates normally, the load 220 can be powered by the power grid; when the power grid operates abnormally, the load 220 can be powered by new energy power generation equipment.

[0051] When the power grid supplies power to the load 220 , the power grid is abnormal, and it may take a long time to start the new energy power generation equipment. In addition, the new energy power generation equipment itself may also have a fault or be under maintenance.

[0052] In this embodiment, the distribution cabinet 111 is provided with a connection module 112, and the connection module 112 is connected to the generator 120. Each distribution cabinet 111 of the distribution module 110 is provided with a connection module 112. The connection module 112 can be a switch or a relay, etc., and each connection module 112 is connected to the generator 120.

[0053] In this embodiment, when the distribution cabinet 111 is not powered on, the connection module 112 corresponding to the distribution cabinet 111 is in a connected state, wherein the distribution cabinet 111 is not powered on may be a state where the power supply source such as the new energy power generation equipment connected to the distribution cabinet 111 does not output electric energy to the distribution cabinet 111, or it may be a state where the distribution cabinet 111 itself is not turned on. When the distribution cabinet 111 is not powered on, the distribution cabinet 111 may not distribute electric energy to the connected load 220.

[0054] In this embodiment, the generator 120 is in the on state when any connection module 112 is in the connected state, and the generator 120 is in the on state when any distribution cabinet 111 in the distribution module 110 is not powered on, so that the corresponding connection module 112 is in the connected state. When the generator 120 is in the on state, it can supply power to the load 220.

[0055] It is understandable that after an abnormality occurs in the power grid, power supply to the load 220 is stopped, and it takes a certain amount of time to start up the new energy power generation equipment. Some or all of the distribution cabinets 111 in the distribution module 110 may be in an unpowered state, that is, there is a connection module 112 in the distribution module 110 that is in a connected state, so that the generator 120 is in a turned-on state and can supply power to the load 220.

[0056] In the related art, when the power grid is out of power, the power generation equipment is usually started manually to provide continuous power supply to the load 220. Due to the uncertainty of the power grid outage, it is difficult to predict the time when the power generation equipment is started, and the power generation equipment makes very loud noise when it is started. Therefore, starting the power generation equipment manually is often time-consuming and labor-intensive, and it is also impossible to guarantee the continuity of power supply of the grid-connected power generation system.

[0057] In the embodiment of the present application, a connection module 112 is provided in the distribution cabinet 111, and the connection module 112 is connected to the generator 120. When the distribution cabinet 111 is not powered on, the connection module 112 corresponding to the distribution cabinet 111 is in a connected state. When any connection module 112 in the distribution module 110 is in a connected state, the generator 120 is in a powered-on state. When the power grid is powered off and switched to new energy power generation equipment for power supply, the generator 120 can be powered on to ensure continuous power supply to the load 220. There is no need to manually start the generator 120, which can save manpower.

[0058] For example, Figure 1 As shown, the distribution module 110 includes multiple distribution cabinets 111. When the power grid is out of power, the entire distribution module 110 is not powered on, and the connection module 112 corresponding to each distribution cabinet 111 is in a connected state. The generator 120 is in a powered-on state when each connection module 112 in the distribution module 110 is in a connected state, thereby ensuring continuous power supply to the load 220.

[0059] According to the microgrid system 100 provided in the embodiment of the present application, the generator 120 is connected to the connection module 112 set on the distribution cabinet 111. When the distribution cabinet 111 is not powered on, the connection module 112 corresponding to the distribution cabinet 111 is in a connected state. The generator 120 is in a powered-on state when any of the connected connection modules 112 is in a connected state. When the power grid is powered off and switched to new energy power generation equipment for power supply, the generator 120 can be powered on to ensure continuous power supply to the load 220.

[0060] In some embodiments, when the power distribution cabinet 111 is powered on, the power distribution cabinet 111 is used to control the on / off state of the corresponding connection module 112 , and the generator 120 is used to control its own startup or shutdown based on the on / off state of at least one connection module 112 .

[0061] In this embodiment, when the power distribution cabinet 111 is not powered on, the corresponding connection module 112 is in a connected state by default. After the power distribution cabinet 111 is powered on, the corresponding connection module 112 can be controlled to be connected or disconnected.

[0062] The generator 120 can control its own on / off state according to the on / off state of all the connection modules 112 in the power distribution module 110. After the generator 120 is turned off, it no longer supplies power to the load 220. The on / off state may include a connected state and a disconnected state.

[0063] In actual implementation, the distribution cabinet 111 can control the connection module 112 to connect or disconnect according to the power supply parameters of the microgrid system 100, or manually issued instructions, etc., where the power supply parameters may include the voltage and power supplied to the load 220.

[0064] It should be noted that, after the power distribution cabinet 111 is powered on, in the case of power failure, the connection module 112 can switch to or maintain the connection state.

[0065] In this embodiment, the connection module 112 can be connected to the generator 120 via a signal line. When the connection module 112 is in a connected state, the signal line is short-circuited and a start-up control command is issued to the generator 120. When the connection module 112 is in a disconnected state, the signal line is disconnected and a shutdown control command is issued to the generator 120.

[0066] The generator 120 may control itself to start up or shut down according to the at least one control instruction received.

[0067] In some embodiments, the generator 120 is configured to control itself to shut down when each connection module 112 is in a disconnected state.

[0068] In this embodiment, when the new energy power generation equipment can meet the power supply demand of the load 220, each distribution cabinet 111 can control the corresponding connection module 112 to disconnect, and the generator 120 can control itself to shut down when each connection module 112 is in a disconnected state, and no longer output electrical energy to the load 220.

[0069] It can be understood that each connection module 112 is in a disconnected state, and each connection module 112 corresponds to a shutdown control instruction. When the instructions received by the generator 120 are all shutdown control instructions, the generator 120 controls itself to shut down.

[0070] In this embodiment, when the new energy power generation equipment cannot meet the power supply demand of the load 220, part or all of the distribution cabinets 111 can control the corresponding connection modules 112 to connect, so as to short-circuit the signal line of the generator 120 and send a start-up control instruction to the generator 120. When the generator 120 receives at least one start-up control instruction, it controls itself to start up.

[0071] It should be noted that, when the power grid supplies power to the load 220 , the generator 120 may be controlled to shut down.

[0072] In the related art, the grid voltage is usually sampled through a controller inside the power generation equipment. When the grid is disconnected, the controller controls the power generation equipment to start. However, after starting the power generation equipment through the built-in controller of the power generation equipment, it may be necessary to wait until the grid is powered again before shutting down the power generation equipment. Even if the new energy power supply equipment in the grid-connected power generation system has sufficient power supply, the power generation equipment will still remain in the turned-on state, increasing the energy consumption of the power generation equipment.

[0073] In an embodiment of the present application, when the new energy power generation equipment can meet the power supply demand of the load 220, each distribution cabinet 111 can control the corresponding connection module 112 to disconnect, and the generator 120 can control itself to shut down when each connection module 112 is in a disconnected state, and no longer output electrical energy to the load 220, thereby reducing the energy consumption of the generator 120.

[0074] In some embodiments, Figure 1 As shown, the power distribution module 110 includes a plurality of power distribution cabinets 111 , and a plurality of connection modules 112 are connected in parallel and connected to two ends of a control switch of a generator 120 .

[0075] In this embodiment, each connection module 112 can be connected to both ends of the control switch of the generator 120 through a signal line. The control switch of the generator 120 can be a switch for controlling the on and off of the generator 120. The generator 120 can receive control instructions through the control switch.

[0076] When any signal line connected to the control switch is short-circuited, the control switch can receive a startup control instruction and control the generator 120 to start up.

[0077] A specific microgrid system 100 is introduced below.

[0078] like Figure 2 As shown, the distribution module 110 includes a distribution cabinet 111, the live wire and the neutral wire of the inverter 210 are connected to the distribution cabinet 111, the distribution cabinet 111 can be connected to the new energy power generation equipment through the inverter 210, the live wire and the neutral wire of the load 220 are connected to the distribution cabinet 111, the live wire and the neutral wire of the generator 120 are connected to the distribution cabinet 111, and the signal line of the generator 120 is connected to the two ends of the connection module 112. The connection module 112 can be a normally closed relay. The generator 120 is set to a two-line starting mode, that is, a mode of controlling the on / off of the connected signal line. When the power grid is disconnected and the distribution cabinet 111 is not powered on, the connection module 112 on the distribution cabinet 111 is in a connected state by default, and the signal line connecting the two-line start of the generator 120 is turned on by default. At this time, the generator 120 is automatically in the on state to ensure the continuity of power supply to the load 220.

[0079] Another specific microgrid system 100 is introduced below.

[0080] like Figure 3 As shown, the power distribution module 110 includes multiple power distribution cabinets 111, and the generator 120 is set in a two-line starting mode, that is, a mode of controlling the on / off of the connected signal line. Multiple power distribution cabinets 111 are connected in parallel with the two-line starting signal line of the generator 120. The power distribution cabinet 111 short-circuits or disconnects the signal line through the connection module 112, and sends a start-up control instruction or a shutdown control instruction to the generator 120 to control the control switch of the generator 120. When different power distribution cabinets 111 send different instructions to the generator 120, the start-up priority of the generator 120 is the highest, that is, one signal line branch is turned on, and the generator 120 can be turned on when a start-up control instruction is received.

[0081] In this embodiment, the generator 120 is set in a two-line starting mode, and the conditions for all distribution cabinets 111 to start the generator 120 are given. When all distribution cabinets 111 are powered normally and there is no need to start the generator 120, the connection modules 112 corresponding to all distribution cabinets 111 are in a disconnected state, and the generator 120 is turned off. At this time, if an abnormal situation occurs in the microgrid system 100, causing all distribution cabinets 111 to lose power at the same time, the connection module 112 corresponding to the distribution cabinet 111 is switched to a default connection state, the signal line connected to the generator 120 is short-circuited, the generator 120 receives a start-up control command, the generator 120 is turned on, and the power supply to the load 220 is not interrupted.

[0082] In this embodiment, the generator 120 is set in a two-line starting mode. Given the conditions for all distribution cabinets 111 to start the generator 120, each distribution cabinet 111 turns on or off the generator 120 according to its own needs. When a distribution cabinet 111 needs to turn on the generator 120, since the distribution cabinet 111 and the generator 120 are connected in parallel and there is a signal line conductive loop, the generator 120 can be started; when all distribution cabinets 111 turn off the generator 120, there is no conductive loop in the signal line connected to the generator 120, and the generator 120 is turned off.

[0083] The embodiment of the present application further provides a control method based on the above-mentioned microgrid system 100 , and the control method of the microgrid system 100 is applied to the generator 120 .

[0084] The control method of the microgrid system 100 provided in the embodiment of the present application, the execution subject of the control method of the microgrid system 100 can be an electronic device or a functional module or functional entity in the electronic device that can implement the control method of the microgrid system 100. The control method of the microgrid system 100 provided in the embodiment of the present application is described below using the electronic device as an example of the execution subject.

[0085] In this embodiment, the power distribution cabinet 111 is configured such that when there is no power, the corresponding connection module 112 is in a connected state.

[0086] like Figure 4 As shown, the control method of the microgrid system 100 includes: step 410.

[0087] Step 410 : When it is determined that any connection module 112 in the power distribution module 110 is in a connected state, control the generator 120 to be in a powered-on state.

[0088] In this embodiment, when the distribution cabinet 111 is not powered on, the corresponding connection module 112 is in a connected state, wherein the distribution cabinet 111 is not powered on may be a state where the power supply source such as the new energy power generation equipment connected to the distribution cabinet 111 does not output electric energy to the distribution cabinet 111, or it may be a state where the distribution cabinet 111 itself is not turned on. When the distribution cabinet 111 is not powered on, the distribution cabinet 111 may not distribute electric energy to the connected load 220.

[0089] In this embodiment, when any distribution cabinet 111 in the distribution module 110 is not powered on, so that the corresponding connection module 112 is in a connected state, the generator 120 is controlled to be in a powered-on state, and the generator 120 can supply power to the load 220 when in the powered-on state.

[0090] It is understandable that after an abnormality occurs in the power grid, power supply to the load 220 is stopped, and it takes a certain amount of time to start up the new energy power generation equipment. Some or all of the distribution cabinets 111 in the distribution module 110 may be in an unpowered state, that is, there is a connection module 112 in the distribution module 110 that is in a connected state, and the control generator 120 is in a turned-on state, so that power can be supplied to the load 220.

[0091] According to the control method of the microgrid system 100 provided in the embodiment of the present application, the generator 120 is connected to the connection module 112 set on the distribution cabinet 111. When the distribution cabinet 111 is not powered on, the connection module 112 corresponding to the distribution cabinet 111 is in a connected state. The generator 120 is in a powered-on state when any of the connected connection modules 112 is in a connected state. When the power grid is powered off and switched to new energy power generation equipment for power supply, the generator 120 can be powered on to ensure continuous power supply to the load 220.

[0092] In some embodiments, the power distribution cabinet 111 is configured to control the on and off of the corresponding connection module 112 when powered on, and the method further includes:

[0093] Based on the on / off state of at least one connection module 112 , the generator 120 is controlled to be turned on or off.

[0094] In this embodiment, when the power distribution cabinet 111 is not powered on, the corresponding connection module 112 is in a connected state by default. After the power distribution cabinet 111 is powered on, the corresponding connection module 112 can be controlled to be connected or disconnected.

[0095] In this embodiment, the generator 120 can be turned on and off according to the on / off status of all the connection modules 112 in the power distribution module 110. After the generator 120 is turned off, it no longer supplies power to the load 220, wherein the on / off status may include a connected state and a disconnected state.

[0096] In actual implementation, the distribution cabinet 111 can control the connection module 112 to connect or disconnect according to the power supply parameters of the microgrid system 100, or manually issued instructions, etc., where the power supply parameters can be the voltage, power, etc. of the load 220.

[0097] It should be noted that, after the power distribution cabinet 111 is powered on, in the case of power failure, the corresponding connection module 112 can switch to or maintain the connection state.

[0098] In this embodiment, the connection module 112 can be connected to the generator 120 via a signal line, and the power on and off of the generator 120 can be controlled by the connected signal line. When the connection module 112 is in a connected state, the signal line is short-circuited, and a power-on control command is issued to the generator 120. When the connection module 112 is in a disconnected state, the signal line is disconnected, and a power-off control command is issued to the generator 120. The generator 120 can be controlled to start or shut down according to at least one control command received by the generator 120.

[0099] In some embodiments, based on the on / off state of at least one connection module 112, controlling the generator 120 to turn on or off includes:

[0100] When each connection module 112 is in the disconnected state, the generator 120 is controlled to shut down.

[0101] In this embodiment, when the new energy power generation equipment can meet the power supply demand of the load 220, each distribution cabinet 111 can control the corresponding connection module 112 to disconnect, and when each connection module 112 is in a disconnected state, the generator 120 can be controlled to shut down and no longer output electrical energy to the load 220.

[0102] It can be understood that each connection module 112 is in a disconnected state, and each connection module 112 corresponds to a shutdown control instruction. When the instructions received by the generator 120 are all shutdown control instructions, the generator 120 can be controlled to shut down.

[0103] In the related art, the grid voltage is usually sampled through a controller inside the power generation equipment. When the grid is disconnected, the controller controls the power generation equipment to start. However, after starting the power generation equipment through the built-in controller of the power generation equipment, it may be necessary to wait until the grid is powered again before shutting down the power generation equipment. Even if the new energy power supply equipment in the grid-connected power generation system has sufficient power supply, the power generation equipment will still remain in the turned-on state, increasing the energy consumption of the power generation equipment.

[0104] In an embodiment of the present application, when the new energy power generation equipment can meet the power supply demand of the load 220, each distribution cabinet 111 can control the corresponding connection module 112 to disconnect, and when each connection module 112 is in a disconnected state, the generator 120 can be controlled to shut down and no longer output electric energy to the load 220, thereby reducing the energy consumption of the generator 120.

[0105] In some embodiments, based on the on / off status of the plurality of connection modules 112 , controlling the generator 120 to turn on or off includes:

[0106] When at least one connection module 112 is in the connected state, the generator 120 is controlled to start.

[0107] In this embodiment, when the new energy power generation equipment cannot meet the power supply demand of the load 220, part or all of the distribution cabinets 111 can control the corresponding connection modules 112 to short-circuit the signal line and send a start-up control instruction to the generator 120. When the generator 120 receives at least one start-up control instruction, the generator 120 is controlled to start up.

[0108] It should be noted that, when the power grid supplies power to the load 220 , the generator 120 may be controlled to shut down.
