Design and simulation of grid connected hybrid solar-WECS using SIMULINK/MATLAB

摘要

As a result of rising concern of global warming and the depletion of fossil fuel reserves, many are looking at sustainable energy solutions to preserve the earth for the future generations. Environmentally friendly solutions are becoming more prominent than ever as a result of concern regarding the state of our deteriorating planet. This paper presents one of the alternate ways for the power generation, which is clean and economical for the future generation. The two sources which are used for power generation are solar and wind. DC output of photovoltaic panel and rectified dc output of Wind energy conversion system(WECS) is fed to the boost converter which is operating in closed loop in-order to maintain constant output power in any environmental condition. It consists of wind turbines with permanent magnet synchronous generator (PMSG). The output of boost converter is feed to the common dc link which is connected to the 3 phase Sinusoidal pulse width modulation (SPWM) inverter, which converts its dc input to 3 phase AC output. Simulated 2KW solar and 3.2KW wind hybrid system. The simulation of whole hybrid model is done in SIMULINK/MATLAB.
