Introduction The clean and sustainable energy has become essential need of modern society and plays a significant role for economic, social as well as human development. Since many decades fossil fuels, have driven our generating stations, supported industries and fuelled our vehicles but these are limited, expensive, depleting day by day [1, 2], and causes heavy risk for environment by the level of raising CO 2 [3]. Therefore, different international agencies promote use of green energy and encourage installing the renewable energy sources (RES) for producing electrical energy. Among available RES, wind is clean, sustainable and fastest developing source of energy recently installed capacity of wind in the world as reached up to 597 GW which shows 49 GW additions in only year 2018[20]. However, stochastic nature of wind imposes severe challenges for electric power utility to maintain continuity in supply and power quality [5]. Wind energy conversion systems (WECS) consists of wind turbine, to produce kinetic energy from wind source and doubly fed induction generator (DFIG) generator with controlling and protection system to generate electrical energy [6]. A special wound rotor induction generator named as DFIG in which not only stator but rotor is also connected with electrical source through power converter. It is preferred with wind turbine because it can be used with variable speed, cost effective and better efficiency [7].
