This paper describes the development of a stationary hybrid power system consisting of a3 kW proton exchange membrane fuel cell (PEMFC) module, a battery set, and solar cells.We design PEMFC control and power managements for the hybrid system, and construct asimulation model based on experimental data. The simulation model is then used toanalyze performance and efficiency of the system, employing different power management strategies. The study comprises three parts: PEMFC control, power management, andthe simulation model. First, we apply robust control to regulate the PEMFC temperatureand current, and achieve root mean square errors of 0.06 C and 0.07 A, respectively.Second, we integrate the hybrid power system and design power management strategiesfor sustainable operation. Third, we develop a Matlab™ SimPowerSystem model based onexperimental data. The simulation results are shown to match the experiments with adeviation of 0.21%. Last, we apply the simulation model to discuss the impacts of differentpower management strategies on system efficiency. Based on the results, the designedcontrollers and power management strategies are deemed effective at improving systemperformance and efficiency. In addition, the developed simulation model can be applied inthe future to develop customized hybrid power system.
