[0040] See attached Figure 1 , Attachment Figure 2 In this embodiment, in normal weather, the photovoltaic power station supplies power to the demand area. During the power supply period, the photovoltaic power station synchronously feeds back the start-up signal of the photovoltaic power station to the control module connector P2.

The drain of field effect tube Q4 and resistor R6 are connected to the ground terminal, field effect tube Q3 is turned on, and the energy storage station continues to supply power to the demand area. When the clock module is in the night period and the power of the energy storage station is lower than the reference signal of cost reduction, field effect tube Q3 is turned off, and the signal at the end of resistor R26 is synchronously fed back to the gate of field effect tube Q9. The voltage difference between the gate of field effect tube Q9 and the source of field effect tube Q9 is higher than the conduction threshold, field effect tube Q9 is turned on, and the power supply signal of the upper power grid is fed back to the connector P7 of the control module. The signal at the connector P7 is fed back to the demand area through the drain of field effect tube Q9, the source of field effect tube Q9, and connector P8 for power supply. In this way, when the photovoltaic power station cannot supply power during the daytime, the energy storage station will supply power, and the upper power grid will supply power during the night period to achieve the purpose of reducing costs and increasing efficiency.

[0042] See attached Figure 2In this embodiment, the power supply signal is fed to the ground terminal through resistors R14 and R15, and the signal at the resistor R15 terminal is the power supply required by the demand area during the maintenance of the upper power grid.

The voltage difference between the gate of the field effect tube Q6 and the source of the field effect tube Q6 is higher than the conduction threshold, and the field effect tube Q6 is cut off. At the same time, the signal at the connector P6 terminal is synchronously fed back to the gate of the field effect tube Q7, and the field effect tube The voltage difference between the gate of Q7 and the source of the field effect tube Q7 is higher than the conduction threshold, the field effect tube Q7 is turned on, and the compensation signal is fed to the ground terminal through the drain of the field effect tube Q7, the source of the field effect tube Q7, the diode D1, and the resistor R3. The signal at the resistor R3 end is fed back to the inverting end of the operational amplifier U2 so that the inverting end of the operational amplifier U2 obtains the reference signal of the compensated cost reduction power. At the same time, the signal at the resistor R14 end is fed back to the non-inverting end of the operational amplifier U5, and the signal at the output end of the operational amplifier U1 is fed back to the inverting end of the operational amplifier U5. When the photovoltaic power cannot supply power to the demand area and the power of the energy storage station is lower than the reference signal of the compensated cost reduction power, the operational amplifier U5 outputs, and the signal at the output end of the operational amplifier U5 is fed back to the gate of the field effect tube Q8. The resistor R16 is used to discharge the parasitic capacitance of the gate of the field effect tube Q8. The field effect tube Q8 is turned off and the upper power grid continues to supply power to the demand area. In this way, the dispatching flexibility of the power supply of the entire power station is further improved while retaining the power required by the demand area after the upper power grid is powered off during maintenance.
