摘要

风能转换系统(WECS)是最受欢迎的可再生能源。本文讨论了电池在电网双馈感应发电机(DFIG)系统中的应用。将电池储能系统(BESS)引入到脱链中，以避免因风的性质变化而引起的功率变化。本文采用了铅酸蓄电池的韦宁等效模型。采用转子侧变换器(RSC)控制器使有功功率最大化。采用电网侧变换器(GSC)实现单位功率因数运行和恒输出功率。通过MATLAB仿真验证了该系统的性能

Power Fluctuation Reduction Using Battery System In DFIG Based Wind Energy Conversion System

Wind energy conversion system (WECS) is the most popular renewable energy resource. This paper discusses about the usage of a battery in a grid interfaced doubly fed induction generator (DFIG) system for power smoothing. Battery energy storage system (BESS) is introduced into de-link to avoid power variation due to varying nature of wind. Thevenin equivalent model of the lead acid battery is employed in this work. Active power is maximized by using rotor side converter (RSC) controller. Grid side converter (GSC) is used to obtain unity power factor operation and constant output power. The performance of the proposed system is verified by simulating in MATLAB
