2.1. Electrical Energy Storage (EES) Electrical Energy Storage (EES) refers to a process of converting electrical energy into a form that can be stored for converting back to electrical energy when required. The conjunction of PV systems with battery storage can maximize the level of self-consumed PV electricity.
The typical framework of the wind-photovoltaic-shared energy storage power station consists of four parts: wind and photovoltaic power plants, shared storage power station, the grid and the user. A portion of the wind and photovoltaic power generation is sent directly to local consumers, while the remainder is kept in shared
The optimal configuration capacity of photovoltaic and energy storage depends on several factors such as time-of-use electricity price, consumer demand for electricity, cost of photovoltaic and energy storage, and the local annual solar radiation. When the benefits of photovoltaic is better than the costs, the economic benefits can be
The PV industry in China entered its period of rapid development during the 21st century because of the significant increase in global demand for PV products.
