Considering the efficiency and cost, Permanent magnet synchronous generator (PMSG) is the mostly preferred for variable speed small and standalone wind energy conversion system (WECS). This machine is one of the main components used in a horizontal axis wind turbine (HAWT) systems. This paper reviews the most common configurations of generators used in wind power systems (WPS), thus highlighted the main advantages and drawbacks of PMSG versus others generators. Despite the fact that the main disadvantage of PMSG related to high cost of permanent magnet, PMSG is not only more reliable and efficient but also needless of the gearbox. The main objective behind using the maximum power point tracking (MPPT) algorithms in WECS during the wind turbine working is tracking and extracting maximum available power from wind power. The MPPT algorithms can be classified into two basics categories: the direct power controller (DPC), and the indirect power controller (IPC).Tip Speed Ratio (TSR) control, and Perturb and Observe (P&O) algorithm are two selected methods of the MPPT algorithms using in WECS; they are reviewed, discussed and compared in this present paper. This review revels that the TSR control is more efficient and has a better dynamic, but requires a precise measure. The P&O algorithm is flexible and simple in implementation, but this method has many performance limits associated with the low efficiency and the optimum step-size problems.

Renewable energy sources are becoming increasingly popular, especially wind power. According to many criteria, the Wind Energy Conversion System (WECS) can be categorized into various types. As part of their application, in the small and standalone Horizontal Axis Wind Turbine (HAWT), most of the generators utilized in these technologies are Permanent Magnet Synchronous Generators (PMSGs) because of their low weight and high efficiency regarding their cost. This study compares and presents the advantages and limitations of various Wind Turbine (WT) types. In addition, a comparison between the PMSG and doubly fed induction generator has been presented. On the other hand, this paper reviews and analyzed the main control strategies applied in WECS. Based on the available studies in the literature, maximum power point tracking control strategies are widely used to harvest the maximum power from wind energy. This control is divided into indirect power control and direct power control. While the pitch angle control strategies can be classified as traditional collective pitch angle control and individual pitch angle control, which is applied to adjust the rotation speed of WT blades. Nevertheless, machine-side converter and grid-side converter control strategies are among the widely used methods for improving power quality. The conventional control strategies reveal many drawbacks and challenges. However, to reduce and even overcome this issue, combining conventional with robust and intelligent controllers may be a good solution.

In recent days, progress has been made in the development of power electronics and control strategies applied to permanent magnet synchronous generators (PMSG), enabling their large-scale use in wind energy conversion systems. This generator offers many benefits, such as low weight and high efficiency relative to cost. In addition, the low noise in direct drive wind turbine based on PMSG technology, thanks to absence of a gearbox. This study aims to present mathematical modeling and control strategies of the variable speed wind turbine based on a PMSG. Applying the field-oriented control strategy to the machine side converter leads to extracting the maximum of the available wind power via the maximum power point tracking (MPPT) approach. First, the MPPT technique without speed control is used to generate the optimum electromagnetic torque. This torque was then utilized to determine the reference stator quadrature current. The entire system was simulated using MATLAB/Simulink software environment. The simulation results reveal a good tracking performance.
