Abstract—This paper presents a method to operate a grid
connected hybrid system. The hybrid system composed of a Pho
tovoltaic (PV) array and a Proton exchange membrane fuel cell
(PEMFC) is considered. The PV array normally uses a maximum
power point tracking (MPPT) technique to continuously deliver
the highest power to the load when variations in irradiation and
temperature occur, which make it become an uncontrollable
source. In coordination with PEMFC, the hybrid system output
power becomes controllable. Two operation modes, the unit-power
control (UPC) mode and the feeder-flow control (FFC) mode, can
be applied to the hybrid system. 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, en
hancing system stability, and decreasing the number of operating
mode changes.
