Abstract

Fuel cells are good energy sources to provide reliable power at steady state and supercapacitor energy storage devices can advance the load following characteristics of a fuel cell by providing a stronger power response to changes in system loading. During motor starts/stops or other considerable steps in load, the super-capacitors provide the balance of energy needed during the temporary load transition periods and also absorb excess energy from the generator source (motor braking). Adding supercapacitor energy storage to distributed power systems improves power quality and efficiency and reduces capital expenses by allowing the systems to be sized more closely to the steady-state power requirements rather than over-sizing the main generator to meet transient loading requirements.
