Example Embodiment
[0027] The key point of the design idea of the present invention is to use wind power photovoltaic electric energy for pumped storage. The pumped storage system contains three types of units: ordinary water pump units, reversible water turbine units and ordinary hydroelectric generating units. The units need system controller intelligence Interpret all information of the system to start and stop.
[0028] See attached figure 1 As shown, this embodiment provides a wind power photovoltaic microgrid pumped-storage power generation system. The system includes microgrid DC bus 1, AC bus 2, system controller 3, photovoltaic power generation subsystem 4, and DC-DC controller 5. Capacitor switch group 6, super capacitor group 23, energy storage battery group 7, two-way DC-DC controller 8, wind power generation subsystem 9, AC-DC controller 10, DC-AC controller 11, water pump switch group 12 , Water pump unit 13, transfer switch unit 14, reversible water turbine unit 15, input switch u...
