Fuzzy Logic Based Controller for a Stand-alone Hybrid Generation System Using Wind and Photovoltaic Energy
نویسنده
چکیده
Fuzzy logic based voltage controller is proposed for hybrid generation scheme using solar and wind energy for isolated applications. The fuzzy logic controller is designed to vary the duty-cycle of the DC-DC converter automatically such that to maintain the load voltage constant. The hybrid scheme comprises one set of fixed capacitor bank and a parallel connected three-phase fixed frequency pulse width modulation (PWM) inverter fed from the solar panels which provide the reactive power requirements to the induction generator. A dynamic d-q axis and steady-state mathematical model for the entire hybrid scheme is presented. The complete system is modelled and simulated MATLAB/Simulink environment. Results from simulations and laboratory tests show that the dynamic reactive power compensation is inherent.
