A battery storage power station, also known as an energy storage power station, is a facility that stores electrical energy in batteries for later use. It plays a vital role in the modern power grid ESS by providing a variety of services such as grid stability, peak shaving, load shifting and backup power.
The construction process of energy storage power stations involves multiple key stages, each of which requires careful planning and execution to ensure smooth implementation.
Additionally, the energy storage system is primarily utilized to optimize the plant's internal operations without providing storage services to external entities. Based on these assumptions, the plant independently determines the scale of the energy storage system and its dispatch strategy.
In the shared mode, the energy storage is collectively owned by a consortium of new energy power plants, with the individual plants within the consortium serving as the users. Due to these differences in ownership and usage rights across the modes, the energy storage configuration schemes also differ.
With the advancement of new energy storage technol-ogies, e.g. chemical batteries and flywheels, in recent years, they have been applied in power systems and their total installed capacity is increasing very fast. The large-scale development of REG and the application of new ESSs in power system are the two backgrounds of this book.
