Paper Title
Control Of Grid Connected Photovoltaic System Under Unbalanced Fault Conditions Using Fuzzy Controller
Abstract
The increasing penetration of distributed power generation into the power system leads to a continuous evolution
of grid interconnection requirements. Individual phase current control with the capability to avoid overvoltage in grid
connected photovoltaic systems under unbalanced voltage sags is proposed to effectively meet grid code requirements for
grid connected photovoltaic systems. During voltage sags grid connected photovoltaic systems should support grid voltages
by inject reactive currents at grid regulations. Such injection must not allow the non-faulty phases grid voltage to go beyond
110% of their nominal value. Yet, in the non-faulty phases grid overvoltage’s can occur, the currents injected into the grid
are balanced by the grid connected photovoltaic system. This grid system is deal with by manipulative individual phases and
injecting unbalanced currents into the grid during voltage sags. This project was verified using MATLAB/SIMULINK
through simulation.
