Conventional sources of power generation are reducing every day there is strong need for sustainable and clean sources of power which could fulfill the demand of electricity. In India context, wind energy power generation play vital role in renewable power generation. Wind energy conversion system (WECS) with control mechanism has become very popular in renewable energy sources power conversion especially in wind energy. Due the development in power electronics devices and advancement in different control techniques and their applicability to extract maximum wind power, doubly fed induction generator (DFIG) has best option as generator in grid connected WECS. This paper presents the different converter control topologies and their comparative study on the basis of type of converter, number of control switches and control schemes of grid connected DFIG in WECS.
