A power flow controller for a Standalone solar PV system employing a three port Luo converter

Abstract

A power flow controller for a standalone solar PV system employing a three port super lift luo converter is presented here. The power flow controller manages power flow between a PV module, battery and a DC load. It consists of a voltage control to regulate output load voltage, MPPT controller to harness maximum power from a solar PV module and a time sharing controller to integrate both. The state space equations of the three port super lift luo converter is developed and is implemented in MATLAB/Simulink. The simulation results obtained for various conditions validate the working of the proposed power flow controller.
