Maximum Power Extraction for Hybrid Renewable Energy Source Fed Micro Grid using Genetic Algorithm MPPT

A noval method of hybrid system with solar power generation and wind power generation to form a microgrid is proposed. It consists of DC-DC interleaved boost converter for step up of DC voltage from the PV panel. Maximum Power Point Tracking (MPPT) technique used here is genetic algorithm. Genetic algorithm provides a good dynamic response over the non-linearity of the solar PV panel input irradiance variation. The renewable sources forms a common DC link bus where the solar and wind power generation is synchronized and the DC voltage is converted to three phase AC output voltage using VSI with Pulse Width Modulation (PWM) pulse generation. The PWM pulse is generated with PI controller. The output of the proposed system is connected to the grid with nominal voltage and nominal frequency. The proposed system is simulated in the MATLAB / Simulink Simulation software.
