POWER QUALITY IMPROVEMENT IN STANDALONE BA TTER Y INTEGRA TED WIND ENERGY SYSTEM

摘要

Regulation of load voltage and frequency is very important in standalone wind energy system under fluctuating wind speeds and changing load conditions. This paper presents vector control strategy for load side inverter in coordination with battery energy storage system for maintaining power balance, voltage and frequency regulation in stand-alone wind-energy system under different operating conditions. The robustness of the proposed control strategy to improve the dynamic performance of standalone PMSG under transient operating conditions is validated using MATLAB/SIMULINK environment.
