[0063] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0064] In an exemplary embodiment, Figure 1 As shown, a V2G charging pile power scheduling method is provided. This embodiment uses the method applied to a vehicle-to-grid (V2G) charging pile as an example. The V2G charging pile is connected to a target transformer and an energy controller; the target transformer is also connected to other charging equipment. In this embodiment, the method includes the following steps:

[0065] S110: Acquire the real-time power and load rate of the target transformer.

[0066] The real-time power can be understood as the active power actually transmitted by the target transformer at any moment.

[0067] The load factor can be understood as the ratio of the target transformer's real-time power to its rated capacity. The rated capacity can be understood as the maximum apparent power that the target transformer can output under rated operating conditions.

[0068] In an optional embodiment, obtaining the real-time power and load rate of the target transformer may include receiving the real-time power sent by the energy controller and a load rate determined based on the real-time power and rated capacity. Optionally, the real-time power and rated capacity may be collected by the energy controller according to a preset period.

[0069] In an optional embodiment, obtaining the real-time power and load rate of the target transformer may include: the V2G charging pile obtains the real-time power and rated capacity of the target transformer, and determines the load rate according to the real-time power and rated capacity.

[0070] S120: Determine a power regulation method for regulating the power of the V2G charging pile based on a comparison between the load rate and a first preset capacity threshold.

[0071] The first preset capacity threshold may be understood as a capacity threshold for determining whether the target transformer is in a capacity-shortage situation.

[0072] The case where the load rate is greater than or equal to the first preset capacity threshold can be understood as a case where the target transformer is undercapacitated. Accordingly, when the load rate is greater than or equal to the first preset capacity threshold, the power regulation method can be understood as a method for supplementing the capacity of the target transformer.

[0073] In an optional embodiment, the power regulation method for regulating the power of the V2G charging pile can be determined based on the comparison between the load rate and the first preset capacity threshold, and the comparison between the real-time power and the preset reverse flow threshold.

[0074] The preset reverse current threshold may be understood as a reverse current threshold for determining whether the target transformer is in a reverse current situation.

[0075] In particular, when the load factor is less than the first preset capacity threshold and the real-time power is less than or equal to the preset reverse current threshold, it can be understood that the target transformer is in reverse current. Accordingly, when the load factor is less than the first preset capacity threshold and the real-time power is less than or equal to the preset reverse current threshold, the power adjustment method can be understood as a method for preventing reverse current in the target transformer.

[0076] S130: According to the power regulation method, the power of the V2G charging pile is regulated until the real-time power meets the preset power requirement and the regulated required power is obtained.

[0077] The preset power requirement may be understood as the real-time power required to ensure that the capacity of the target transformer is sufficient, or the real-time power required to stop the reverse flow of the target transformer.

[0078] Among them, adjusting the required power can be understood as adjusting the power of the V2G charging pile to meet the charging and discharging control power required for automatic backflow prevention and capacity replenishment.

[0079] S140: Reporting the regulated required power to the energy controller, so that the energy controller controls the charging and discharging timing information of other charging devices according to the regulated required power.

[0080] The charge and discharge timing information may be understood as the time sequence information of charge and discharge.

[0081] In an optional embodiment, the charging and discharging timing information of other charging devices may be determined based on the adjustment required power and the real-time power and required power of each other charging device.

[0082] In an optional embodiment, the remaining power after deducting the adjusted power requirement can be determined based on the capacity of the target transformer and the adjusted power requirement. The charging and discharging timing information of the other charging devices can be determined based on the preset strategy, the remaining power, the real-time power of each other charging device, and the required power.

[0083] Among them, the remaining power after deducting the regulated demand power can be understood as the remaining power after deducting the V2G charging pile used for automatic backflow prevention and basic capacity supplementation functions.

[0084] In the above-mentioned V2G charging pile power scheduling method, the comparison between the load rate and the first preset capacity threshold can reflect the current state of the target transformer capacity. By comparing the load rate with the first preset capacity threshold, the power adjustment method for power adjustment of the V2G charging pile is determined, and the power of the V2G charging pile is adjusted according to the power adjustment method, thereby realizing power adjustment of the target transformer. That is, when the capacity of the target transformer is insufficient, the capacity of the target transformer can be supplemented by adjusting the power of the V2G charging pile. When the target transformer has reverse current, the target transformer can be prevented from reverse current by adjusting the power of the V2G charging pile, so that the capacity of the transformer reaches a dynamic balance.

[0085] As mentioned above, the situation where the load rate is greater than or equal to the first preset capacity threshold can be understood as insufficient capacity of the target transformer. In this case, the insufficient capacity of the target transformer can be overcome by reducing the charging power and increasing the discharging power.

[0086] Based on this, in an exemplary embodiment, a power regulation method for power regulation of the V2G charging pile is determined based on a comparison between the load rate and a first preset capacity threshold, including: when the load rate is greater than or equal to the first preset capacity threshold, determining the power regulation method to be to reduce the current charging power of the V2G charging pile, and after reducing the current charging power, when the load rate is greater than or equal to the first preset capacity threshold, increasing the current discharge power of the V2G charging pile.

[0087] In an optional embodiment, the power regulation method can be determined as reducing the current charging power of the V2G charging pile according to a first preset ratio, and after reducing the current charging power, when the load rate is greater than or equal to the first preset capacity threshold, increasing the current discharge power of the V2G charging pile according to a second preset ratio.

[0088] Optionally, the first preset ratio and the second preset ratio may be the same. Alternatively, the first preset ratio and the second preset ratio may be different. Exemplarily, the first preset ratio may be 50%. Exemplarily, the second preset ratio may be 50%.

[0089] In an optional embodiment, after reducing the current charging power of the V2G charging pile, a delay may be made before continuing to check the comparison between the load rate and the first preset capacity threshold. Based on this, the power adjustment method may be determined to be reducing the current charging power of the V2G charging pile and, after a first preset period of time after reducing the current charging power, increasing the current discharge power of the V2G charging pile if the load rate is greater than or equal to the first preset capacity threshold.

[0090] Exemplarily, the first preset time period may be 100 milliseconds.

[0091] In an optional embodiment, the above embodiments may also be combined, that is, the power regulation method may be determined to reduce the current charging power of the V2G charging pile according to a first preset ratio, and after a first preset time period after reducing the current charging power, when the load rate is greater than or equal to the first preset capacity threshold, the current discharge power of the V2G charging pile may be increased according to a second preset ratio.

[0092] Accordingly, the preset power requirement may include: the real-time power is less than or equal to the product of the rated capacity of the target transformer and the first preset capacity threshold. Accordingly, adjusting the power of the V2G charging pile according to the power adjustment method until the real-time power meets the preset power requirement may include: adjusting the power of the V2G charging pile according to the power adjustment method until the real-time power is less than or equal to the product of the rated capacity of the target transformer and the first preset capacity threshold.

[0093] In this embodiment, when the load rate is greater than or equal to the first preset capacity threshold, that is, when the capacity of the target transformer is insufficient, the power adjustment method of first reducing the current charging power of the V2G charging pile and then increasing the current discharge power of the V2G charging pile can trigger the capacity replenishment mechanism, timely replenish the capacity of the target transformer, and relieve the pressure on the target transformer.

[0094] As previously mentioned, if the load rate is less than the first preset capacity threshold and the real-time power is less than or equal to the preset reverse current threshold, it can be understood that the target transformer is in reverse current. In this case, the reverse current of the target transformer can be overcome by reducing the discharge power or increasing the charging power.

[0095] Based on this, in an exemplary embodiment, a power regulation method for power regulation of the V2G charging pile is determined according to a comparison between the load rate and a first preset capacity threshold, including: when the load rate is less than the first preset capacity threshold and the real-time power is less than or equal to the preset reverse current threshold, determining the power regulation method to reduce the current discharge power of the V2G charging pile, and after reducing the current discharge power, when the real-time power is less than or equal to the preset reverse current threshold, increasing the current charging power of the V2G charging pile.

[0096] In an optional embodiment, the power regulation method can be determined as reducing the current discharge power of the V2G charging pile according to a third preset ratio, and after reducing the current discharge power, when the real-time power is less than or equal to the preset reverse current threshold, increasing the current charging power of the V2G charging pile according to a fourth preset ratio.

[0097] Optionally, the third preset ratio and the fourth preset ratio may be the same. Alternatively, the third preset ratio and the fourth preset ratio may be different. Exemplarily, the third preset ratio may be 50%. Exemplarily, the fourth preset ratio may be 50%.

[0098] In an optional embodiment, after reducing the current discharge power of the V2G charging pile, a delay may be made before continuing to check the comparison between the real-time power and the preset reverse current threshold. Based on this, the power adjustment method may be determined to be to reduce the current discharge power of the V2G charging pile and, after a second preset period of time after reducing the current discharge power, increase the current charging power of the V2G charging pile if the real-time power is less than or equal to the preset reverse current threshold.

[0099] Exemplarily, the second preset time period may be 100 milliseconds.

[0100] In an optional embodiment, the above embodiments may also be combined, that is, the power regulation method may be determined to reduce the current discharge power of the V2G charging pile according to a third preset ratio, and after a second preset time period after the current discharge power is reduced, when the real-time power is less than or equal to the preset reverse current threshold, the current charging power of the V2G charging pile may be increased according to a fourth preset ratio.

[0101] Accordingly, the preset power requirement may include: the real-time power is greater than or equal to a preset reverse current threshold. Accordingly, adjusting the power of the V2G charging pile according to the power adjustment method until the real-time power meets the preset power requirement may include: adjusting the power of the V2G charging pile according to the power adjustment method until the real-time power is greater than or equal to the preset reverse current threshold.

[0102] In this embodiment, when the load rate is less than the first preset capacity threshold and the real-time power is less than or equal to the preset reverse current threshold, that is, when reverse current occurs in the target transformer, the anti-reverse current mechanism can be triggered by first reducing the current discharge power of the V2G charging pile and then increasing the power adjustment method of the current charging power of the V2G charging pile. By timely absorbing the power discharged by the target transformer to the power grid, the occurrence of reverse current can be prevented.

[0103] In one embodiment, Figure 2 As shown, a V2G charging pile power scheduling method is provided. This embodiment uses the method applied to an energy controller as an example. The energy controller is connected to a target transformer and a V2G charging pile respectively; the target transformer is also connected to other charging equipment. In this embodiment, the method includes the following steps:

[0104] S210, obtaining the adjustment demand power obtained after power adjustment of the V2G charging pile; wherein, the adjustment demand power is obtained by determining the power adjustment method based on the comparison between the load rate of the target transformer and the first preset capacity threshold, and then adjusting the power of the V2G charging pile according to the power adjustment method.

[0105] In an optional embodiment, the adjustment required power can be obtained at the V2G charging station side. The process of determining the adjustment required power can refer to steps S110 to S130 and will not be repeated here.

[0106] In an optional embodiment, obtaining the adjustment required power obtained after power adjustment of the V2G charging pile may include: receiving the adjustment required power reported by the V2G charging pile.

[0107] S220 : When the load rate is greater than or equal to the second preset capacity threshold, determine the charge and discharge timing information of other charging devices according to the adjustment required power.

[0108] The situation where the load rate is greater than or equal to the second preset capacity threshold can be understood as a situation where the station where the target transformer is located is in a capacity shortage situation.

[0109] The charge and discharge timing information may be understood as the time sequence information of charge and discharge.

[0110] In an optional embodiment, the charging and discharging timing information of other charging devices may be determined based on the adjustment required power and the real-time power and required power of each other charging device.

[0111] In an optional embodiment, the remaining power after deducting the adjusted power requirement can be determined based on the capacity of the target transformer and the adjusted power requirement. The charging and discharging timing information of the other charging devices can be determined based on the preset strategy, the remaining power, the real-time power of each other charging device, and the required power.

[0112] Among them, the remaining power after deducting the regulated demand power can be understood as the remaining power after deducting the V2G charging pile used for automatic backflow prevention and basic capacity supplementation functions.

[0113] S230: Control other charging devices to charge and discharge the target transformer according to the charge and discharge timing information.

[0114] In an embodiment of the present application, after power adjustment of the V2G charging pile, the energy controller can determine the charging and discharging timing information of other charging devices based on the adjustment demand power when the load rate is greater than or equal to the second preset capacity threshold, that is, when the capacity of the charging station is insufficient, to ensure that the target transformer is charged and discharged through other charging devices, thereby supplementing the capacity of the charging station.

[0117] The charging equipment may include a V2G pile and other charging equipment except the V2G pile.

In an optional embodiment, a V2G device that supports a single gun can be used for automatic backflow prevention and basic capacity replenishment.

[0139] S313: The V2G charging pile is reset according to the reset instruction.

[0140] Based on the above embodiments, Figure 4 As shown, the present application also provides a V2G charging pile power scheduling system. The V2G charging pile power scheduling system may include two DC charging guns, namely a first DC charging gun and a second DC charging gun. The first DC charging gun and the second DC charging gun are used to charge electric vehicles.

[0141] Among them, the transformer can be used to convert high-voltage electricity from the power grid into a voltage suitable for charging piles and electric vehicles.

[0142] Among them, the energy controller is a comprehensive energy management controller for the station, which is used to receive the control strategy of the cloud platform and the energy data fed back from the charging pile side (such as charging and discharging power, charging equipment status, etc.); send control charging and discharging instructions to the charging piles, etc., to realize the global scheduling and management of the station energy, coordinate the allocation of transformer capacity, increase the transformer capacity through discharge of the charging piles, and execute the charging and discharging strategy.

[0143] Among them, V2G charging piles are used to use electric vehicle batteries as distributed energy storage units and interact bidirectionally with the power grid.

[0144] The V2G charging pile includes: a power conversion and on-off control unit, a detection and metering unit, an execution and control unit, a charging and discharging management unit with a built-in fifth-generation mobile communication technology (5G) communication module, and a charging execution unit.

[0145] Among them, the power conversion and on-off control unit may include: a circuit breaker, which is used to control the power input of the power grid or the power of the charging equipment to be reversed to the AC bus under the transformer to prevent short circuits and overcurrents; a bidirectional AC-DC converter, which is used to realize the conversion of electric energy forms, convert the AC power output of the transformer into DC power, power the DC charging gun and electric vehicles, or invert the power of the electric vehicle battery to the AC bus under the transformer; an auxiliary power supply, which is used to provide power for the battery management system (BMS) of the charging and discharging vehicle.

[0146] Among them, the detection and metering unit may include: a bidirectional current / voltage detection meter (2 groups): corresponding to the first DC charging gun circuit and the second DC charging gun circuit, respectively, for real-time monitoring of the charging and discharging current and voltage parameters of the branch circuit; a first insulation detection module, for detecting the loop insulation status for the charging and discharging path corresponding to the first DC charging gun; a second insulation detection module, for detecting the loop insulation status for the charging and discharging path corresponding to the second DC charging gun.

[0147] Among them, the execution and control unit may include: a first DC contactor group and a second DC contactor group, which correspond to the first DC charging gun and the second DC charging gun respectively, and are the executive elements for switching the branch power on and off; controlled by the built-in 5G communication module charge and discharge management unit, the branch charge and discharge circuit is connected or disconnected, and the working state of the dual-gun wheel charging (charging, discharging or standby) is flexibly switched in conjunction with the wheel charging and discharging strategy; the first auxiliary power supply relay and the second auxiliary power supply relay are used to control whether the auxiliary power supply provides power to the BMS of the charging and discharging vehicle.

[0148] The charging and discharging management unit, with a built-in 5G communication module, serves as the intelligent control core of the charging pile and integrates 5G communication capabilities. It exchanges data with the cloud platform and the station's integrated energy management controller in real time via the 5G network, uploading charging pile status (such as charge and discharge power, device faults, and battery status), receiving remote control commands (such as charge and discharge strategy adjustment, charge and discharge power control, cycle charge and discharge timing setting, and identification as a device for automatic backflow prevention and basic capacity replenishment in the system), and receiving transformer capacity information (including real-time power and transformer rated power) from the station's integrated energy management controller. When the V2G pile is activated as the system's automatic backflow prevention and basic capacity replenishment device, it controls its own charging and discharging, as well as its charge and discharge power, according to the transformer capacity information (including real-time power and transformer rated power) sent by the station's integrated energy management controller. (For example, it actively reduces discharge power or initiates charging in the event of transformer backflow; and actively reduces charging power or initiates discharge in the event of insufficient transformer capacity.)

[0149] In one embodiment, in an area where 5G signals are limited, wireless fidelity (WiFi) or industrial Ethernet can also be used to achieve communication between the charging pile and the controller.

[0150] In one embodiment, when the V2G pile is activated as the system's automatic backflow prevention and basic capacity supplement equipment, the V2G pile comprehensively judges the charging and discharging strategy adjustment, charging and discharging power control, and rotation charging and discharging timing setting of the remote control instructions based on the transformer capacity information (including real-time power, transformer rated capacity, and load rate) issued by the station integrated energy management controller and the remote control instructions issued by the station integrated energy management controller.

[0151] In one embodiment, a V2G charging pile for automatic backflow prevention and basic capacity supplementation functions can directly monitor the real-time output power of the transformer and perform automatic backflow prevention and basic capacity supplementation control.

[0152] In one embodiment, the V2G charging pile is only used for the automatic backflow prevention function and does not automatically replenish capacity.

[0153] The charging execution unit includes a first DC charging gun and a second DC charging gun, each directly connected to the electric vehicle, serving as the final execution component of power transmission. In charging mode, it delivers DC power after DC / AC conversion to the vehicle battery. In V2G discharge mode, it receives DC power from the vehicle battery and transmits it back to the internal circuit of the charging pile, achieving bidirectional energy flow.

[0154] The cloud platform, serving as the system's remote monitoring and management hub, connects via the network to the charging and discharging management unit and the integrated energy management controller within the station, which includes a built-in 5G communication module. This platform aggregates energy data from multiple charging stations and stations for big data analysis (e.g., regional energy demand forecasting, global transformer capacity optimization, and charging and discharging behavior statistics). Furthermore, it issues macro-control instructions to stations and charging stations (e.g., regional charging and discharging power allocation, peak-valley electricity price response strategies), enabling cross-station and multi-device collaborative management and supporting interaction between the power grid and vehicle clusters in the V2G model.

[0155] Among them, electric vehicles communicate with the DC charging gun of the charging pile through the BMS, report the battery status (such as the remaining power (State Of Charge, SOC), charging and discharging capabilities, etc.), receive charging pile control instructions, absorb and store electrical energy in the battery during charging, and transmit the electrical energy stored in the battery back to the charging pile and the power grid through the charging gun during discharging, cooperate with the dual-gun charging and discharging strategy, and participate in the transformer capacity optimization.

[0156] The photovoltaic system and energy storage system can supplement or regulate power for the grid. In one embodiment, a small energy storage battery can be configured as a power buffer pool to smooth out current surges when the power of the dual-gun fluctuates, improving transformer stability.

[0157] The V2G charging pile power dispatching system includes a power loop represented by a solid line, a communication loop represented by a dotted line, and a control feedback loop represented by a dotted line.

[0158] Among them, the power circuit is the main channel for electric energy transmission, starting from the transformer, passing through the circuit breaker, DC / AC conversion (or inverse conversion during reverse discharge), through the DC contactor group and DC charging gun, and finally connected to the electric vehicle battery (forward transmission during charging and reverse transmission during discharge), realizing the two-way flow of electric energy between the power grid and the vehicle battery.

[0159] Specifically, the communication circuit may include the internal communication circuit of the charging pile, the communication circuit between the charging pile and the outside world, and the communication circuit between the integrated energy management controller of the station and the cloud platform via the 5G network. In the internal communication circuit of the charging pile, the charging and discharging management unit with the built-in 5G communication module communicates with the bidirectional current / voltage detection meter, insulation detection module, and DC charging gun via the CAN bus. The charging and discharging management unit with the built-in 5G communication module in the communication circuit between the charging pile and the outside world interacts with the cloud platform via the 5G network. The charging pile and the integrated energy management controller of the station communicate using wired Ethernet or other industrial-grade serial communication standards.

[0160] In the control feedback loop, the charging pile's built-in 5G communication module and charge-discharge management unit control the operation of actuators such as the DC contactor group and auxiliary power relay, and detect their feedback. The station's integrated energy management controller directly collects power parameters such as total output power, voltage, and current on the transformer's output side.

[0161] Based on the above embodiments, Figure 5 As shown, the present application also provides a V2G charging pile power scheduling system. The V2G charging pile power scheduling system may include a single DC charging gun.

[0162] Among them, the description of each unit in the V2G charging pile power scheduling system can be found in the above embodiment and will not be repeated here.

[0163] In other embodiments, the V2G charging pile power scheduling system may further include N DC charging guns; wherein N is a positive integer greater than or equal to 3.
