At the same time, the coordinated control problem of multiple voltage and reactive power resources was fully considered. By establishing an optimal voltage control model, precise control of the power station voltage was achieved, significantly improving the coordinated control effect of photovoltaic energy storage power stations.
The optimal energy storage power of photovoltaic energy storage power station is obtained based on the real-time data such as the charge state of the storage system. This paper constructs an optimal voltage control model through ADP algorithm and obtains the optimal coordinated control strategy.
Photovoltaic energy storage power station is a combined operation system including distributed photovoltaic system and energy storage system. The overall structure of a photovoltaic storage power station is shown in Figure 1. Figure 1. Photovoltaic energy storage power station.
When a photovoltaic energy storage power station is under coordinated control, the photovoltaic energy storage power station shall be set for a fixed period of time in order to ensure the safety of the photovoltaic energy storage power station being connected to the power grid (Wang et al., 2021).
