SUMMARY Fuel cells, as components of cogeneration systems and battery energy storage systems, can be used as power sources in an isolated power system in complex housing at times of blackout. This paper reports study results on such isolated power systems. Simulation models are developed and the results are compared with measured values of active power, reactive power, and voltage. Good agreement is obtained. In this analysis, it is found that there is a stability limit in such inverter power source operation. The stability limit is expressed by a short circuit power ratio that is similar to the one in conventional ac systems. Nonlinear load switching is also studied to demonstrate stable operation.
