Optimal Configuration Method of High-Rate Characteristic Energy Storage Battery Based on Wind Level Suppression

Aiming at the application scenario of energy storage to stabilize wind power fluctuations, a method for optimal configuration of energy storage batteries is proposed in consideration of high rate characteristics. Use the net present value method to construct an economic model that considers life cycle costs and operating process benefits. Analyze the impact of the energy storage battery rate characteristics on the available capacity, consider the life weight factor, and establish a method for calculating the operating life of the energy storage under high-rate charge/discharge based on the throughput energy. With the goal of optimal energy storage battery economy, the optimal rate configuration is found, so as to form an energy storage configuration plan that meets the technical and economic characteristics. The simulation analysis of a wind farm energy storage capacity configuration example verifies the effectiveness and economic value of the configuration method.
