An Energy Storage Strategy With Two-Parameter Controller and Buffer Capacitor for Off-Grid Type Wind Power System
摘要
Abstract
To improve dissatisfactory wind power quality caused by wind speed fluctuation, using energy buffer and closed-loop feedback combining with piecewise linearity an energy storage strategy with two-parameter controller and buffer capacitor for off-grid type wind power system is proposed. Utilizing Matlab/Simulink software, the modeling and simulation of the proposed control strategy are performed, and the constant current and constant voltage charging of lithium battery energy storage system, dynamic energy storage compensation and energy storage under low wind speed are implemented, thus the correctness of the design scheme is validated. Since the designed power management unit is enable to store up energy under low wind speed, the designed two-parameter controller possesses such features as high utilization rate of wind energy and suitability for wide range of wind speed. The proposed controller is available for reference to follow-up development and research.关键词
