Abstract: The conventional sources of energy are depleting and emphasis is now focused on renewable energy. Wind energy is one of the renewable sources having great potential. It is cheap and requires less maintenance but also have issues associated with it. The main issue associated with Wind turbines (WT) is the unpredictable nature of wind. This makes it difficult to get a constant frequency and constant voltage from wind turbines driven by the variable speed. This paper presents method of regulating the output voltage for standalone wind turbine driven by variable speed wind. The method is based on the using voltage regulator for the fluctuating voltage of wind turbine driven by variable speed. The regulated voltage is supplied to utility. Battery system is also proposed for the system which will provide power when wind regulated voltage is dropped from a threshold value due to low wind speed or absence of wind.
