    The new control law of a supercapacitor (SC) based storage device combining a proton exchange membrane fuel cell (PEMFC) as a hybrid power plant is presented in this paper. To realize this goal, a Hamiltonian control law (or an interconnection and damping assignment passivity-based control IDA-PBC) is proposed. The paper deals with the new control algorithm to stabilize FC/SC hybrid system under constant power load stability issue in dc distributed network. To validate the proposed control approach, a hardware system is implemented with a high-performance microcontroller (CPU 64 bits, dual-core, 2 GHz). Also, the dc microgrid used in experimental test rig consists of a PEMFC of 2500 W, 50 V and a supercapacitor module of 188.88F 51.3V. The Experimental results show that the proposed controller has excellent control performance during a load-drive cycle under constant power load condition.
