Abstract: At present scenario, renewable energy sources are needed to meet the energy demand. They also mitigate environment pollution problems. The shortage of electrical energy demand can be meeting with renewable energy resources. A wind turbine (WT) and photovoltaic (PV) solar panels are primary energy sources. Grid connected renewable energy source like wind energy and solar energy are used to connect the hybrid system. Power electronics converters are used as interfacing device between hybrid system (WT & PV) and the utility grid. These converters are commonly based on a voltage source inverter (VSI) connected to the supply network. Grid side current control PWM technique is applied to the voltage source inverter which reduces THD value to less than 1%. Power balancing under heavy loaded conditions is also evaluated. The power factor correction is also determined. The simulation of power balancing conditions, total harmonic distortion (THD) and power factor correction (PFC) are studied with MATLAB Simulink.
