Wind and Solar Cell-Based Distribution System for Different Load Variations Using Fuzzy Logic Controller

P Trimurtulu, K Bhaskara Rao

Abstract


The proposed system presents power-control strategies of a grid-connected hybrid generation system with versatile power transfer. This hybrid system allows maximum utilization of freely available renewable energy sources like wind and photovoltaic energies . For this, an adaptive MPPT algorithm along with standard perturb and observe method will be used for the system.Also, this configuration allows the two sources to supply the load separately or simultaneously depending on the availability of the energy sources. The turbine rotor speed is the main determinant of mechanical output from wind energy and Solar cell operating voltage in the case of output power from solar energy. Permanent Magnet Synchronous Generator is coupled with wind turbine for attaining wind energy conversion system . The inverter converts the DC output from non-conventional energy into useful AC power for the connected load . This hybrid system operates under normal conditions which include normal room temperature in the case of solar energy and normal wind speed at plain area in the case of wind energy. A fuzzy based PWM system will be designed to reduce the harmonic ripples. The simulation results are presented to illustrate  the operating principle, feasibility and reliability of this proposed system.
