摘要: The hybrid power systems can efficiently produce energy using an optimal combination of renewable generation systems, but in order to continuously sustain the required load demand, a backup source is necessary. proton exchange membrane fuel cell system be used as non-polluting solution for source, instead diesel generator. variability and demand flow balance on common bus will mitigated by storage system. architecture may based DC or AC AD/DC bus, each which has advantages disadvantages. use semi-active active topology, depending control objectives imposed implemented its side. This chapter analyze topology Energy Storage System. most technologies devices have been presented this chapter. models system, battery, ultracapacitors, wind turbine, photovoltaic panel, converters, were also briefly presented. Performance indicators efficient sources mentioned last sections chapter, along with main research directions conclusions.
