Synchronization of Grid Connected PV System Using PI Controller

P BhogiRaju, A Ramakrishna

Abstract


Grid connected solar system consists ofconverters Circuits are organized in two differentways one is DC/DC boosters and another is PWMInverter. This combination results decrement ofQuality and efficiency of electric power, this paperreflects the use of a single phase 13- level photovoltaic (PV) inverter in solar system connected togrid with a pulse width-modulated (PWM) controlsystem. The rapid variations in radiation can beremunerated by Digital proportional-integralcontroller. This inverter gives a less harmonicdistortion and significant power factor over fivelevel inverters and is examined and experimentedthrough simulation.

Keywords


Grid connected, photovoltaic ( PV ) , proportional–integral ( PI ) current control.
