Harmonics mitigation and reactive power compensation through a CC-VSI/APF WECS

The increasing interest to utilise wind energy as a power source prompted more researches to be dedicated to the efficient integration of this power source into the current grid. In this paper, one avenue to achieve this efficient utilisation, through the use of current- controlled voltage source inverter (CC-VSI) integrated with a permanent magnet synchronous generator (PMSG) wind energy conversion system (WECS) is presented. The system with the CC-VSI acting as an active power filter (APF) is capable of mitigating harmonics as well as providing reactive power support, which in turn increase the efficiency of the conversion system and correct power factor to unity. The proposed system increases the effectiveness of the utilisation of wind energy as one of the future energy source.
