Abstract: The rapid development of energy storage promotes the consumption of clean energy and ensures the safe and stable operation of power grid, but it also brings new challenges to the mechanism design of energy storage to participate in the power market. Based on the experience and enlightenment of energy storage participating in the spot market in the domestic and overseas, taking Zhejiang Province as an example, the benefits of energy storage participating in spot energy market and frequency regulation auxiliary service are simulated and calculated respectively. The results show that due to the influence of energy storage conversion efficiency, power loss and the cost of transmission and distribution system, the overall income of energy storage participating in the electric energy market does not achieve the expectation, but it has certain advantages in the frequency regulation auxiliary service.

Key words: energy storage, spot market, frequency regulation auxiliary service, power market
