Abstract

In This paper wind, solar and fuel cells based stand alone cogeneration systems are presented for remote area utilities applications. This type of co generation system output voltages are not constant or stable in always. The generated output voltages are directly connected to the loads, without battery bank or energy storage devices. The PI, fuzzy control method was proposed in this paper using svpwm, such that the output voltage of converter circuit is constant even though input voltages are fluctuation conditions. A three phase multilevel inverter with static and dynamic load was examined to validate for proposed work in MATLAB environment.
