【摘要】 风力发电机组输出的有功功率受风速变化影响而波动,影响电能质量并增加发电系统对电网的冲击。本文提出了一种微型压缩空气储能和飞轮储能组成的混合储能系统结构,在此基础上,设计了一种基于模糊推理方法实现的风力发电-混合储能系统有功功率平滑控制策略,解决了风力发电机有功功率输出波动的问题。利用Matlab/Simulink平台,通过算例对控制策略进行了仿真研究。研究结果表明,所提出的功率控制策略具有可行性和有效性,能较好地平抑风力发电机输出有功功率波动,减小风机并往时对电网的冲击。更多还原

【Abstract】 The power output of wind generator(WG) is fluctuant and irregular,in view of the unpredictable nature of wind,and then influences the power system stability heavily.This paper presents a new type of Hybrid Energy Storage System(HESS) consisted of Micro-Compressed Air Energy Storage(MCAES) and Flywheel Energy Storage System(FESS),based on the analysis of the structure and characteristics of the HESS,a scheme of wind power smooth assisted through hybrid energy storage system taking advantage of fuzzy control technology has been proposed to stabilize the power output of wind turbine.The model of WG-HESS is built up and simulation is done using Matlab/Simulink.The simulation results show the feasibility and efficiency of the proposed control strategy.更多还原
