Abstract

In this paper the sustainability of a 2 KW hybrid of wind and battery arrangement is examined for meeting the necessities of a stand-alone dc load. This development is convenient with the development of control schemes for small level wind turbine that requires relatively low power. As wind flow is erratic in nature, hence to make sure incessant make available of power appropriate storage device as battery is used as backup. A charge controller for battery bank supported turbine most power point tracking and battery state of charge is developed to make sure controlled charging and discharging the battery. The mechanical safety is secure by means of pitch control method. The automatic protection of the WECS is also secure by means of pitch management technique. Each the control schemes are integrated and effectualness is valid by testing it with numerous Load and wind profiles in MATLAB/SIMULINK.

Keywords: Permanent-magnet generators, wind energy, wind turbine, weak grid
