Voltage stability is concerned with the ability of a power system to maintain acceptable bus voltages under normal conditions and after being subjected to a disturbance, Using Fuel cells (FCs) have several benefits and in this paper we study the effects of FCs on power systems via simulation a single machine (DG as small gas turbine coupled with a FC) in the DigSilent area for different PF of FC. Different PF for FC obtained with control the DC to AC inverter. We found that by control the PF of FCs, we can increase the limitation of reactive generation of overall system and improve the V-P and V-Q characteristics of overall system
