Application analysis and prospect of electrochemical energy storage in power grid

In order to promote the optimization and upgrading of the energy industry, the development and utilization of renewable energy has been increased, and the planning, operation and dispatching management of the power grid will face important change. Advanced large-scale energy storage technology is urgently needed to improve the power generation characteristics of renewable energy. This paper discussed application of electrochemical energy storage technology in the grid systems, and maked deep analysis on security, cost and technical characteristics, and summarized advantages and disadvantages of various types of electrochemical energy storage. Finally, the application prospect of electrochemical energy storage in the grid system and analyzed and prospected.
