Increasing the Efficiency of Grid Tied Micro Wind

2014-12-23Major problem with grid tied micro wind turbine is synchronization and wind variability Due to this problem the stability of available grid gets reduced The stability can be achieved by output power control of the turbine Major part of many countries like India the annual mean wind speed is not high The rated wind speed of turbine remain around 11 m/s and cut in is around 3 5 m/s
