Model Predictive Control with Variable Sampling Time for Improving Power Quality of PMSG-based Wind Energy Conversion System in DC Microgrid

DC Microgrid 연계형 PMSG 기반 풍력에너지 변환 시스템의 전력 품질 개선을 위한 가변 샘플링 시간이 적용된 모델예측제어

This paper proposes a method for improving the power quality of PMSG-based wind energy conversion system based on model predictive control in DC Microgrid. The MPC has a fast dynamic response. However, a large torque ripple deteriorating power quality is generated by a large and fixed switching period. On the other hand, the proposed method improves the power quality by setting the sampling time having zero torque error. The validity of the proposed method is verified through PSIM simulation.
