The main direction these days is to use renewable energy to cover the power demand instead of fossil fuels. There are many reasons to make renewable energy resources be used than the fossil fuels, such as depletion of fuels and the need to use clean energy. The wind energy conversion system (WECS) is the most beneficial renewable energy resource. The significant advantage of WECS is that wind power is cost-effective, environment friendly, domestic installation, and sustainable. So challenging endeavor is exerted to enhance the WECS behavior. This paper reviews the different methods to improve the performance of the WECS based permanent magnet synchronous generator (PMSG). The performance enhancement of the WECS is represented in smoothing and maximizing the generated power and controlling the output voltage. The main control methods will be illustrated in this work, such as the various types of control topologies and the different optimization methods used. The advantages and drawbacks of each class will be discussed in this work.
