The storage system is assumed to be integrated with the solar power station and will be replaced once in the middle of the operational lifespan of the power station.
On the grid side, specialized energy storage power stations will replace traditional thermal power plants to provide peak and frequency regulation functions and ensure the safety of the power grid operation.
Solar-and-energy storage-integrated charging stations typically encompass several essential components: solar panels, energy storage systems, inverters, and electric vehicle supply equipment (EVSE). Moreover, the energy management system (EMS) is integrated within the converters, serving to regulate the power output.
In addition, the cost reduction of solar power, and similar trends in storage technologies like lithium-ion batteries (28), brings an opportunity to integrate storage systems into solar power stations.
All the other choices could also help enhance the matching of demand with solar supply, potentially reducing the storage capacity needed in the solar-plus-storage system. In this case, the cost advantage of solar PV could be further amplified.
The major components of a standalone solar PV system with pumped storage include a power generator (PV array), an energy storage subsystem (consisting of two reservoirs, penstocks, pumps, and turbines/generators), an end-user (load), and a control station. The system is illustrated in Fig. 1.
