A photovoltaic (PV) cell connected to the grid system has been modeled in MATLAB environment. Various characteristics have been plotted with changing atmospheric condition. An operating point at which photovoltaic cell exhibits maximum efficiency and generates maximum power is tracked by, a method called voltage Based Maximum Power Point tracking (VMPPT). To inject a sinusoidal current into the grid system, two modulations techniques namely; Sine PWM and State Vector PWM (SVPWM) have been implemented, and their performance is evaluated based on different parameters. Simulation results demonstrate the fast and effective response.
