Abstract
The extraction of wind energy has been essential to fulfill the load demand which is not supplied by conventional sources at the end of 2012. In India, total capacity of wind power is very high, approximately 102,788 MW, in comparison to installed capacity. This paper reviews different permanent magnet synchronous generator (PMSG) operated in wind energy systems. A complete survey has been made towards the new contributions for harmonic compensation and new efficient topologies in the last five years to improve the efficiency, reliability and cost of the wind energy system. Different power electronic converters, which are connected between generator and the load/ grid, have been investigated on based on harmonic compensation, efficient working, and high power rating conversion. The wind generation system is still a challenge to extract smooth power from wind. To improve the power quality of the system such as islanding problem and power variation, different renewable storage systems are discussed and compared. Finally, discussion about the different controller is presented to fulfill the load or grid requirement.
