In recent years, China's new energy power generation industry has developed steadily. According to statistics, as of the end of October 2021, the cumulative installed capacity of renewable energy power generation in China exceeded 1 billion kilowatts, doubling the end of 2015。
However, new energy with wind power, photovoltaics and other as the main body, the output power is unstable, with large fluctuations, randomness and other characteristics, easy to cause problems such as grid frequency instability. The configuration of "new energy + energy storage" has multiple functions such as peak shaving, valley filling, and frequency regulation, which can ensure the safe and stable operation of the power system and help the consumption of new energy.
