It is a rational decision for users to plan their capacity and adjust their power consumption strategy to improve their revenue by installing PV–energy storage systems. PV power generation systems typically exhibit two operational modes: grid-connected and off-grid .
Energy storage is an important flexible adjustment resource in the power system. Because of its bidirectional flow of energy, it is very suitable to be used in power system as a peak regulation method.
The PV–storage system comprises a series of interconnected components, as illustrated in Fig. 1. These include PV modules, an energy storage system and controller, a grid-connected inverter, and a bidirectional meter.
According to the generator output curve and energy storage output curve, the peak regulating effect of energy storage after parameter optimization is better than that without parameter optimization.
Secondly, to minimize the investment and annual operational and maintenance costs of the photovoltaic–energy storage system, an optimal capacity allocation model for photovoltaic and storage is established, which serves as the foundation for the two-layer operation optimization model.
