HYBRID DISTRIBUTED POWER DISTRIBUTION SYSTEM WITH AN INTEGRATED THREE PORT CONVERTER FOR PHOTOVOLTAIC CELL /BATTERY

Abstract

       Photovoltaic  cell (PV) system /battery hybrid power units have a great influence with many researchers focusing in the modern years.The conventional power distribution systems for PV cell /battery hybrid power units there need to be two independent power converters which are uni-directional DC-DC converter and a bi-directional converter. In this work  it consider the complete energy management and control operation for the PV system /Battery hybrid system power distribution with the utilization of the three port power converter. The integrated bi-directional DC-DC converter consists of the power switch with full bridge converter.

        The energy management and control strategy are been presented for power balance among the  three port power converter at different scenarios.The simulations that are being conducted using the Matlab/Simulink software to demonstrate the operation performance of the proposed PV system /battery .Hybrid distributed power generation system with the corresponding control algorithms, where the MPPT control loop, the battery charging/discharging management loop are enabled accordingly in different operating scenarios.
