Abstract

This concept of paper proposes here is the power control of the grid connected photovoltaic
system by using the distributed power flow controller and how the total working capacity of the grid
connected photovoltaic system is improved with the different control techniques. Consequently the
interconnection of grid is used for the improving of the power system reliability, best performance
and economical cost. However the grid connected p-v system is designed with the boost converter
and the voltage source inverter for controlling the grid side monitoring system. This control
technique of the grid system may reduce the power quality issues like voltage sag, swell and the
harmonic distortions. To optimize these problems in p-v system, the FACTS devices are most
suitable devices which are used in transmission lines. The DPFC is a device which there is no
common DC link and is used as efficient device to eliminate the harmonic distortions, voltage sag
and swell in power system. Due to the non-linearity and abnormal conditions in the power systems,
there is a deviation in voltage and frequency. This paper presents the concept of the control strategy
of grid connected p-v system by using DPFC may be eliminate the distortions very effectively and
the result analysis is analyzed with the help of simulation process using Matlab/Simulink.
