چکیده مقاله:
Wind energy systems are increasingly being used in different distributed generation systems. Due to changeablenature of wind speed, selection of a suitable method as regards where the wind farm is, has a vital importance.Maximum power point tracking (MPPT) plays a critical role to improve the efficiency of wind energy conversion system(WECS). This Paper provides a comparison between common MPPT methods, including power curve, tip speed ratio(TSR), optimal torque control (OTC) and perturb & observe (P&O). Then their effects on behavior of an islanded microgrid during and after overloading and short circuit fault has been investigated. Based on results in the literature, it isclear that OTC has better behavior than other methods and then TSR. After all because of methods nature, OTC, TSR,power curve and P&O has better performance respectively. The studied system is a micro grid with high share ofrenewable energy resources containing a WECS driven by permanent magnet synchronous generator (PMSG), asynchronous diesel unit and some active and reactive loads.
