Wind energy source (WES) is one of the most prominent sources of electrical energy in years to come. WES. as a renewable source. has no impacts on the climate issues and greenhouse gases (GHG) emissions. The increasing concerns about environmental problems demand green. renewable. and sustainable ideas. Wind turbines along with solar energy and fuel cells are possible innovative solutions for this dilemma. WES is a non-depleting. site-dependent. non-polluting. and a potential source of the alternative energy option. Wind energy has already reached a penetration level in many countries. which raises some technical problems concerning grid integration. WE has to overcome some technical as well as economic barriers if it should produce a substantial part of electricity. In power systems. the principal objective of the control strategy is providing economical and reliable power as possible while improving the power quality [5.6]. The wind energy conversion system (WECS) is not just be used for generating electricity from the wind. but also about using this energy efficiently. Wind turbine (WT) is often equipped with a blade pitch control (BPC) for high-quality power generation from wind source and decreasing mechanical fatigue.
