Abstract:

It will lead to the problem of frequency adjustment when the large-scale new energy integrated in the power grid, and large capacity power energy storage is one of the effective solutions for the problem. By analyzing the types of power energy storage and its application scenarios, this paper points out that there are four large capacity energy storage technologies such as electrochemical energy storage, pumped storage, flywheel energy storage and compressed air energy storage which play a role in the power grid frequency adjustment, introduces the performance feature of the four large capacity power energy storage, and summarizes the properties which participate in grid load adjustment, primary frequency modulation, secondary frequency regulation. The characteristic of peak frequency modulation are compared, and the development tendency of research in the future is pointed out.

Key words: large capacity power energy storage, peak regulation and frequency adjustment, electrochemical energy storage, pumped storage, flywheel energy storage, compressed air energy storage
