The main difficult in present power system is that, it fails to meet increasing load demand and growing of population. Consideration of environmental problems and greenhouse effect, renewable energy sources are alternative to meet this requirement. So that, DG systems to become a future energy source due to advantage of environmental conditions and energy costs linked with addition of existed energy systems. Out of all DG systems, PV and Wind energy systems are alternative to each other to maintain the load supply reliability. A DC-DC converter with MPPT technique is used to regulate the DG systems. A INC algorithm is proposed as MPPT technique in this paper. The inverter of hybrid system is implemented with Fuzzy technique to improve power quality. This hybrid system is tested in Matlab/Simulink environment and verified the results for various load conditions to meet the demand.
