The ANALYSIS OF A GRID CONNECTED PV-FC POWER MANAGEMENR SYSTEM

Abstract

This paper shows the work done on the method to operate a grid connected hybrid system which is
composed of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell .With the proton
exchange membrane the hybrid system output power becomes controllable. Here the system uses two
operation modes, the unitpower control (UPC) mode and the feeder-flow control (FFC) mode. This papers
discusses the coordination of two control modes, the coordination of the PV array and the proton
exchange membrane fuel cell in hybrid system and the way in which the reference parameters are
determined. The proposed operating strategy with a flexible operation mode change always operates the
The PV array operates at maximum output power and the Proton Exchange membrane cell in its high
efficiency performance band, using the proposed strategy which has a flexible operation mode thus
improving the performance of system operation with enhance stability and reduction in number of
operating mode change. The coordination of two control modes, the coordination of the PV array and the
PEMFC in the hybrid system, and the determination of reference parameters are presented. The proposed
operating strategy with a flexible operation mode change always operates the PV array at maximum
output power and the PEMFC in its high efficiency performance band, thus improving the performance of
system operation, enhancing system stability.
