Fuel cell (FC) is emerging as a clean and nonpollutant energy source and is being used widely in most of the transport and microgrid applications. However, certain applications demanding fast dynamic response are restricting usage of FC on account of its lifetime issues. Slow dynamic response of FC is not suitable to provide transient load demands, typically arising in electrical vehicles during acceleration...
This paper presents a novel strategy for a hybrid energy management system consisting of a photovoltaic (PV) array, a polymer electrolyte membrane fuel cell (PEM-FC) as energy sources and Lithium ion (Li-ion) battery as an auxiliary energy storage. Such hybrid combination brings the reliability, redundancy and an overall energy efficiency in the system. DC-DC converters are used to interface PV-FC-battery...
FC is a clean energy source alternative for electric vehicle and certain microgrid operations. However to compensate its slow dynamics and inability for tracking fast load transients it needs some auxiliary storage system like battery, supercapacitor (SC) or ultracapacitor (UC). This paper considers hybrid combination of FC-UC, as it has added advantages over other storage systems like instantaneous...
Fuel Cells have emerged as one the most efficient energy conversion devices which convert chemical energy into electricity. It is a common practice to use supercapacitor or battery with a fuel cell to compensate for a high instantaneous power requirement during transients in applications such as hybrid electric vehicle, smart grids etc. This paper presents a non-linear controller design method for...
The paper presents passivity based control strategy for hybrid energy management system comprising of fuel cell and ultra capacitors. Industrial applications like electrical vehicles and certain microgrid combinations are using fuel cell as a clean energy alternative for the requirement of DC supply. But due to its slow dynamics it needs to be often combined with auxiliary storage systems like battery,...
