For clarity of description of the control unit 110 in the embodiment of the present application, it will be described in detail with reference to fig. 2. Fig. 2 is a schematic diagram of a control unit according to an embodiment of the present application. As shown in fig. 2, the control unit 110 includes: a first control unit 111 and a second control unit 112.
The first control unit 111 and the second control unit 112 are in communication connection, so that data after the platform area control method executed by the first control unit 111 is transmitted to the second control unit 112 through a CAN (Controller Area Network, controller area network bus) bus protocol inside the control unit 110, or the second control unit 112 transmits data in the target device 120 to the first control unit 111 through a CAN bus protocol inside the control unit 110.
The first control unit 111 is a centralized control device, and may be used to execute the method for controlling a zone. The first control unit 111 may be set according to practical situations, for example, the first control unit 111 may be the charging system control unit 121 (Charge System Control Unit, CSCU), which is not limited herein.
The second control unit 112 is a monitoring device, and is configured to receive the processing data after the first control unit 111 executes the zone control method, and further control the target device 120 through the data received by the input capturing/output comparing unit 122, so as to implement charge and discharge control of the energy storage unit 130.

The energy storage device provided by the embodiment comprises a control unit, target equipment and an energy storage unit; the control unit is respectively in communication connection with the target equipment and the energy storage unit, and the energy storage unit is connected with the target equipment; the control unit is used for executing the platform area control method. Therefore, the energy storage device provided by the application can share the power supply pressure of the transformer in the preset transformer area when the power supply pressure of the load of the power load is larger in the power consumption peak period by arranging the energy storage unit in the transformer area control system, so that the transformer in the preset transformer area is prevented from being in an overload running state for a long time, and the service life of the transformer in the preset transformer area is prolonged; further, the load level of the transformer in the load low valley period of the power load can be improved, so that peak clipping and valley filling are achieved, and the utilization rate of the transformer is improved.
It should be noted that, the power load on the platform area control system provided in this embodiment is an ac load.
For example, the first collecting device collects the actual operating power Pcc of the transformer operated in parallel at the current time and the actual electric power p_load of the electric load, and the second collecting device collects the electric power p_grid of the charging system control unit 121 in the control unit 110 at the current time. In order to make the actual operating power of the district control system be in an equilibrium state, i.e. Pcc =p_load+p_grid, the control unit 110 in the energy storage device 100 in the district control system needs to be controlled, so that the target device 120 is controlled by the control unit 110, and charge and discharge management control of the energy storage unit 130 is realized, thereby realizing adjustment of the electric power p_grid in the energy storage device 100, and further making the actual operating power of the district control system be in an equilibrium state.

The method for controlling a zone according to the above embodiment of the present application is explained and illustrated in detail below with reference to the accompanying drawings. Fig. 3 is a schematic flow chart of a method for controlling a cell according to an embodiment of the present application. The method for controlling the platform area provided by the embodiments of the present application may be implemented by a computer device, where, for example, a control function that may be integrated by the computer device may be integrated in advance with a control unit in the energy storage device, so as to implement, by executing the method for controlling the platform area, that actual power consumption of a load of a preset platform area is in a power balance state. As shown in fig. 3, the method may include:
S210, determining a first voltage parameter and a second voltage parameter from the multiphase voltage parameters of the transformer area. Wherein the first voltage parameter is less than the second voltage parameter.
Specifically, with continued reference to fig. 1, the target device 120 may be, for example, a current transformation device or an ac-dc conversion unit, or the like. The control unit 110 in the energy storage device 100 may, for example, obtain a multi-phase initial voltage parameter of the ac/dc conversion unit, where the multi-phase initial voltage parameter is obtained by converting a dc electrical signal of the energy storage unit 130 into an ac electrical signal by the target device 120 when the energy storage device 100 is in a discharging state, and then connecting the ac electrical signal to a bus on a low voltage side of the transformer by a cable at a line end of a preset transformer area. When the energy storage device 100 is in a charged state, the target device 120 receives the ac signal on the transformer bus, converts the ac signal into a dc signal, stores the dc signal in the energy storage unit 130, and obtains the multiphase initial voltage parameter during discharging at this time. Or when the energy storage device 100 is in a discharging state, the direct current signal of the energy storage unit 130 is converted into an alternating current signal through the target device 120, and then is connected to a bus on the low-voltage side of the transformer through a cable at the line end of the preset transformer area, so that the obtained multiphase power parameters during charging can be obtained; when the energy storage device 100 is in a charged state, the target device 120 receives the ac signal on the transformer bus, converts the ac signal into a dc signal, stores the dc signal in the energy storage unit 130, and obtains the multiphase power parameter during discharging at this time.
For example, when the control unit 110 acquires the multiphase initial voltage parameter of the target device, the second acquisition device may acquire the value of the multiphase initial voltage parameter of the target device in real time. The multi-phase initial voltage parameter may be selected according to practical situations, for example, the multi-phase initial voltage parameter is a three-phase initial voltage parameter, such as va_grid, vb_grid, and vc_grid, which are not limited herein. Determining a first voltage parameter and a second voltage parameter according to the acquired array of the multiphase voltage parameters, wherein the first voltage parameter is an initial minimum voltage parameter vmin=min (va_grid, vb_grid, vc_grid) of the three-phase voltage parameter; the second voltage parameter is an initial maximum voltage parameter vmax=max (va_grid, vb_grid, vc_grid) of the three-phase voltage parameter.

Specifically, with continued reference to fig. 1, when the energy storage device 100 is in a discharging state, the dc electrical signal of the energy storage unit 130 is converted into an ac electrical signal by the target device 120, and then is connected to the bus on the low voltage side of the transformer through the cable at the line end of the preset transformer area, thereby obtaining the multiphase power parameter during charging; when the energy storage device 100 is in a charged state, the target device 120 receives the ac signal on the transformer bus, converts the ac signal into a dc signal, stores the dc signal in the energy storage unit 130, and obtains the multiphase power parameter during discharging at this time.
As the control device 110 acquires the multiphase power parameters of the target device 120, the multiphase power parameters of the target device may be acquired in real time by the second acquisition device. The multiphase power parameters may be selected according to practical situations, for example, the multiphase power parameters are three-phase power parameters, such as pa_grid, pb_grid, and pc_grid, which are not limited herein.

starting target equipment to output target power of at least one phase so as to control at least one phase voltage of the station area respectively; or, the target equipment is started to output the target voltage of at least one phase so as to respectively control the voltage of at least one phase of the platform area.
Specifically, when the zone control method is started, the target device 120 in the energy storage device 100 is started to perform electrical parameter control, for example, when the electrical parameter is power, the target device is started to output at least one phase of target power to control at least one phase of voltage of the zone respectively, for example, when the zone is three-phase electrical parameter control, the target power of each phase output by the target device corresponds to each phase of voltage control of the control zone. Or if the electrical parameter is voltage, the target device may be started to output the target voltage of at least one phase, so as to control the voltage of at least one phase of the console area respectively, and then the target voltage of each phase output by the target device corresponds to the voltage control of each phase of the console area. And further, the energy storage unit 130 is subjected to charge and discharge management control, so that the load of the power utilization load on the power supply line of the preset station area is realized, and the power balance state is achieved in the power utilization peak period.
