This paper evaluates the performance of a grid connected hybrid system. The hybrid system consists of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell (PEMFC). Two operation modes, the unit-power control (UPC) mode and the feeder-flow control (FFC) mode, can be applied to the hybrid system. The objective of the paper is to coordinate the two control modes and determine the ref...

Electricity loads in buildings are increasingly supplied by distributed renewable generation sources such as photovoltaic (PV) modules or fuel cells. Often these systems are combined with an electricity storage to raise the level of self-consumption in buildings and to reduce the load on the electric grid. PV production and battery storage are both inherently based on direct current (DC) power....
