Abstract

This paper presents the integration of photovoltaic (PV), fuel cell (FC) and energy storage systems for reliable power generation. The PV is the primary energy source, fuel cell is the auxiliary power source where as battery and ultra capacitor both are considered for their different power density to supply transient and steady load respectively. In this system FC is used as main power source and power from PV whenever available is harvested completely with storage system compensating for power fluctuations. This topology has high efficiency, modularity and fuel flexibility. The sources in this hybrid system complement each other very well against environmental variations and load variations. Of the many storage systems the use of ultra capacitor gives advantage of absorbing and contributing to power transients quickly and efficiently.To increase the reliability of the system source Fuel cell has been chosen to keep the battery fully charged. The battery sources are connected to DC bus by DC-DC converters. In this work, Fuel cell is chosen to work for a limited period. This will avoid the over sizing of the Fuel cell and limit the operational cost of the system. In this paper, the structure of the hybrid power system is described. The proposed hybrid power system is then verified by numerical simulation.
