Design and Analysis of a Grid Connected Hybrid Energy Generation System for Parkey Beach, Bangladesh

In recent days, the hybrid energy generation system from renewable energy sources has received a great deal of interest. But connecting multiple energy sources to the grid is always a challenging issue. Herein, the combined grid connected energy generation system, based on wind and solar energy, has been designed and simulated to achieve stable and harmonic free grid voltage. In order to maintain a stable output voltage on the grid, a control scheme for power converters has been proposed where advanced PWM technology has been used to reduce harmonics and switching losses. A multi-stage inverter topology has also been presented in this article. The aim of this multistage inverter is to approximate the performance of a square wave to a pure sine wave. Doubly Fed Induction Generator mechanism is observed for wind energy conversion. The modeling framework based on MATLAB / Simulink was used to simulate the design model. A site located at Parkay Beach in Chittagong, Bangladesh, has been selected to use realistic solar irradiance and wind speed data in the simulation. Simulated results have steady peak voltage and lower harmonics. Thus, affirm the performance of the design.
