This paper proposes a new topology for hybrid wind-solar generation system for isolated loads. The main focus is to reduce the size of battery for critical loads and supply non-critical loads directly from the stator side of DFIG. DFIG is controlled from rotor side with back to back connected PWM converters. Vector control scheme is being used in synchronously rotating reference frame for Rotor side converter (RSC) and Load side converter (LSC) does not require any special control scheme resulting in the lesser complex control circuitry. Reactive power demand for critical, non-critical loads and induction machine will be supplied from DC link capacitor. DC link voltage will be maintained as constant by DC-DC converter, connected to control battery charging and discharging. Since there are three possible options at DC link (wind, solar & battery backup), the size of battery will be lesser. The proposed scheme is modelled, simulated and analysed in MATLAB.
