Abstract:

In order to promote energy transformation and optimize energy mix of China,the proportion of renewable energy in the energy mix has been increasing. However, the randomness and volatility of renewable energy generation brings negative impact on the safe and stable operation of power grid. Since electrochemical energy storage technology has the characteristics of rapid response and flexible power adjustment, it facilitates the safe and stable operation of power grid. Firstly, the types of energy storage technologies and completed electrochemical energy storage projects are summarized. After that, the role of energy storage in power system stability control is explained from three aspects: frequency stability, static voltage stability and transient voltage stability. Finally, the expectation on the participation of electric vehicle charging stations and electric vehicles in power system regulation is made. Energy storage technologies will be the key component of power systems.

Key words: renewable energy, energy storage technology, frequency stability, voltage stability, electric vehicle, frequency regulation and peak shaving
