Battery energy storage system for 10kW wind turbine output stabilization

배터리 에너지 저장장치를 이용한 10kW 풍력발전출력 안정화 시스템 개발

This paper presents a simulation model and results of experiment about analysis of grid-tied wind turbine generator with batteries. The system consists of two inverters and a bidirectional DC/DC converter. These inverters are to capture the maximum active power under varying wind conditions and to keep the DC-link voltage magnitude at a specific level. And the bidirectional DC/DC converter makes battery charging or discharging depend on power gap between wind turbine output and local load.
