Performance Improvement and Analysis of Stand- Alone Hybrid Wind /Battery/DG Power Generation System

نویسنده

  • H. Ashfaq
چکیده

This paper presents a standalone hybrid power generation system based on low speed wind energy conversion system (WECS) using a variable speed permanent magnet synchronous generator (PMSG) with battery storage and diesel generator (DG). Different types of power management strategies are presents for minimal use of DG. For each PMS, mathematical model is developed based on the power balance (between the supply side and the load side), the battery bank charging/discharging limits (upper and lower energy limits) and the sizing of system elements. The topology for the same with different PMS has been verified using MATLAB Simulink based simulations. Keywords—Wind energy conversion system, Permanent magnet synchronous generator, Isolated system, FFT analysis, DG.
