Wind energy is a renewable energy and its running cost negligible as wind is freely available. The non -renewable energy are being exhausted and therefore there is a need to switch to renewable sources of energy. For utilizing wind energy, wind turbines are used and different parameters like, shape and size of the blades, wind speed, generator characteristics etc. are considered in calculating the efficiency of the turbine. This paper deals with the performance study of the output from the permanent magnet synchronous generator PMSG coupled with the wind turbine. In this case performance test is conducted with two variable speeds and the reactive power, active power, voltage and current waveforms of the inverter is plotted using SIMULINK. Keywords: PQ Control; Voltage Source Inverter (VSI); Boost Converter; Permanent Magnet Synchronous Generator (PMSG).

Introduction Day by day, the gap between electricity generation and the demand for it is rapidly increasing. This is due to extinction of fossil fuels which is one of the main sources of electricity generation. So there is a need to find an alternative way by which we can generate electricity more efficiently and the best way to generate electricity efficiently is by utilization of renewable sources of energy. There are lot many sources of energy like solar, wind, hydro, tidal, geo-
