This paper presents simulation results of a grid interactive Uninterruptible Power Supply (UPS) system using fuel-cell and ultra-capacitor storage. The system incorporates 40 kW of grid input supply, a 45 kVA power conditioning unit capable of operating in both inverting and charging modes, and a 16-Ah battery bank. It was aimed to demonstrate the capability of the system to provide uninterrupted power, demand side management function and load voltage stabilization in a grid which experiences frequent blackouts and under/over voltage problems. Fuel cells (FCs) are being considered as a impending substitute in long term to replace diesel/gasoline combustion engines in vehicles and emergency power sources. However, soaring cost and sluggish dynamic response of FC still persevere as the main hurdles for wider applications. To remedy this problem, energy storage systems like ultra capacitors (UC) with adequate power capacity have to be incorporated. UC are in general very faster in charging and discharging operation and can also be helpful in improving power factor at the point of inter-connection. The results prove the efficiency of fuel cell and ultra-capacitor in maintaining uninterruptable supply to load centers.
