Pumped storage-based standalone photovoltaic power generation system
As illustrated, when solar power generation is higher than energy demand, the surplus of energy is used to pump water from a low reservoir to a high reservoir, storing energy in the form of gravitational potential energy of the water (charging/pumping mode, Fig. 1 a). When power needs to be dispatched, water is allowed to flow back downhill
