Beschreibung
Zusammenfassung:	Disclosed is a photovoltaic storage flexible grid-connected system, comprising a thermal power plant service unit, a power electronic transformation SOP unit and a photovoltaic storage microgrid unit. The thermal power plant service unit comprises a 6kV plant service bus and is used for transferring power to a power grid system. The photovoltaic storage microgrid unit comprises a 400V comprehensive energy bus and is used for transferring power to the thermal power plant service unit by means of the power electronic transformation SOP unit. A high-voltage side of the power electronic transformation SOP unit is connected to the 6kV plant service bus, and a low-voltage side of the power electronic transformation SOP unit is connected to the 400V comprehensive energy bus, the power electronic transformation SOP unit being used for providing a power transfer channel when the thermal power plant service unit and the photovoltaic storage microgrid unit transfer power.
