Abstract:The system introduced in this paper adapts various power-control strategies of a grid-connected hybrid generation system with versatile power transfer. With this hybrid system, the freely available renewable energy sources like wind and photovoltaic energies can be utilized effectively. For this, an adaptive MPPT algorithm along with standard perturbs will be used for the system. Also, this configuration allows the two sources to supply power to the load either 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 solar energy for output power. Permanent Magnet Synchronous Generator is coupled with the wind turbine for attaining wind energy conversion system. This hybrid system operates under normal conditions which include normal room temperature in the case of solar energy and normal wind speed at the plain area in the case of wind energy. A PWM Controller is used for an inverter which is replaced with Hysteresis controller. The simulation results are presented to illustrate reliability of this proposed system. .
