Abstract

The depletion of fossil fuels and rising demand for energy has lead the search for various alternative sources of energy. Solar being inexhaustible provides sustainable power to the rural areas. The renewable energy system has been promoted worldwide because of the Kyoto agreement. The design and simulation of a single-phase two-stage photovoltaic system is proposed in isolated mode of operation. The maximum power point tracking is performed based on perturb and observe MPPT technique. A boost converter topology is used to obtain the constant DC voltage from solar photovoltaic system. The modeling and simulation of solar array, dc-dc boost converter, a voltage source inverter and an LC filter is done in matlab simukink. Perturb and observe based tracking of maximum power point and design of PI controller to control the voltage source inverter with PWM switching are the key feature of this work. Single phase inverter with bipolar voltage switching is used. The square wave output produced by the inverter is fed to a low pass filter to obtain a sinusoidal wave. The PV system is operated under isolated mode of operation. The Total Harmonic Distortion (THD) of load voltage is analyzed.
