Operation and Control of PV System using Different Modulation Techniques

A high penetration of distributed solar photovoltaic resources is becoming a worldwide reality for many electricity distribution utilities. This paper present the design and analysis of PV module connected with D.C. Boost Converter and Perturb and Observe (P&O) algorithm that is used for maximum power point tracking (MPPT) to maximize the generated power and it is further connected to three phase inverter whose switches are controlled by different Pulse Width Modulation techniques i.e. Sinusoidal Pulse Width Modulation (SPWM) and Space Vector Pulse Width Modulation (SVPWM). In the A. C. systems quantity is not more important than quality. To improve the quality of output ac voltage in this system we are using two different techniques and also results are analyzed using FFT analysis to find out the total harmonic distortion (THD). MATLAB/SIMULINK environment is used to simulate the proposed system.
