Modeling and control of solar/fuel cell powered hybrid power systems

In this paper, a modeling and supervisory control strategy for a solar/fuel cell powered hybrid power system are developed for stand-alone residential applications. Using Ultra-Capacitors(UC) and PhotoVoltaic (PV) panel together with a Fuel Cell(FC) system is a possible solution to provide sufficient power supplies for residential areas. Each model for the FC, PV and UC are developed, and four modes of operations of the proposed hybrid power system are defined for the proposed supervisory control. The proposed hybrid power system is simulated and analyzed based upon the modeling and the supervisory control algorithm in Matlab/Simulink environment.
