ANALYSIS OF PV SYSTEM EMBEDED TO DISTRIBUTION GRID FOR ACTIVE & REACTIVE POWER SUPPLY TO GRID

Abstract

In this paper presents a grid connected photovoltaic (PV) system with maximum power point tracking
(MPPT). The Voltage Source Inverter (VSI) has been connected between the dc output of PV system and the ac grid. The
control strategy applied is based on instantaneous reactive power theory (p-q theory). According to this theory during the
sunlight system send active power to grid and same time compensate the reactive power of load and compensate the
harmonics. During no sunlight available system only compensate reactive power of load and harmonics. The applicability
of the p-q theory control method has been verified on the test system using simulation in Matlab/Simulink.
