Application of energy storage technology and its role in system peaking and frequency modulation

Photovoltaic and wind power have experienced rapid development, but they are facing problems such as the abandonment of wind and other renewable resources, and through recent years of development, energy storage technology has become a key technology, and now it has become the main way of power grid frequency modulation, it has a response. The length of time and the precise tracking characteristics have been recognized by people. This paper introduces the characteristics and applications of various energy storage technologies in peak shaving and frequency modulation for reference.
