Abstract

This work deals with design and simulation of photovoltaic system connected to the grid. Maximum power is extracted from solar panel by means of boost convert which is operated by means of perturb and observe method. The output of the boost converter connected to the three-phase inverter is wired to the grid. Inverter is controlled by the fuzzy control technic. In this control technique, load current is taken as reference current and grid current is taken as actual current. Error in direct and quadrature axis currents is given to the fuzzy controller which generates the reference voltage. These are transferred into the ‘abc’ frame and compared with the carrier signal, and generated pulses are given to the inverter. The fuzzy current control method switches the power device in the inverter such that minimizes the error between the grid currents and the load current. Grid current tracks the reference current with less transient time, steady-state error, acceptable total harmonic distortion. This is implemented through the MATLAB simulation.
