Abstract
A standalone wind driven Permanent Magnet Synchronous Generator (PMSG) enhanced with storage battery bank and DC dump load is proposed in the current publication. This scheme is aimed to extract the maximum power and provides fixed DC bus voltage under different atmospheric and loading conditions. The system feeds a DC- motor driving a water pump, and additional AC- loads are supplied. To accomplish the functions required from the proposed system, and to maintain the DC bus voltage fixed, a maximum power point tracker and a number of different controller types are utilized, irrespective of the wind speed, loading condition and the state of charge (SOC) of the battery bank. The designed power management strategy is implemented to achieve proper operation of the system components towards full utilization. The proposed scheme is validated through simulation results under different operating conditions.
