Renewable energy has typical intermittent characteristics, strong random fluctuation of output, and insufficient support capacity at peak load. Therefore, the power supply guarantee of high proportion of renewable energy power system is facing severe challenges. Renewable energy allocation and energy storage can solve the problem of random volatility of renewable energy to a certain extent. In this context, based on the operation mechanism of electrochemical energy storage, this paper establishes the Renewable energy + Energy storage operation optimization model considering the operation safety characteristics of electrochemical energy storage. In order to provide technical support for the planning and construction of related enterprises, the paper explores the effectiveness of large-scale renewable energy configuration of electrochemical energy storage, and analyzes the impact of different energy storage operation modes which is solved by CPLEX. The results indicate that renewable energy configuration energy storage can improve its confidence capacity and reduce the peak valley difference rate of net load, but the specific effect is closely related to the operation mode of energy storage.
Key words: Energy storage / Operation mode / Renewable energy / Confidence capacity
