This paper discusses optimal operation strategies of a cluster of microturbines (MTs) for electrical load-following applications. Cluster operation ensures higher operational flexibility, but raises the issue of taking into account the partial-load MT characteristics, in terms of energy efficiency and pollutant emissions. In particular, from experimental results the NOx and CO emissions exhibit nonlinear...
During the past years, research and development actions in fuel cell technology have been stepped up within industry and universities. Therefore, fuel cells are now displacing towards commercial forwardness, or expecting a discovery within the next few years. Being an extensive technology, fuel cells are encountered with different designs and in several applications. The most important fields are...
Renewable energy technologies such as wind power and photovoltaic energy are getting attentions from view points of energy conservation and environmental issue. However, fluctuation of output power of renewable energy may cause excess variation of voltage or frequency of the grid. Increase of the amount of renewable energy would violate the quality of the grid. The micro grid in which dispersed power...
Fuel cells (FCs) hold great promise as a clean energy conversion technology. A large research effort is underway to develop the FC for applications ranging from small portable electronic devices to automotive transport, as well as residential combined heat and power supplies. These applications have a large emerging market and widespread adoption should lead to a reduced dependence on fossil fuels...
Major technical issues related to increased reliance on distributed generation systems (DGS). In distribution systems including lack of: appropriate dynamic models reliable control approaches, efficient dispatch methods, and control strategies to facilitate the connection of distributed generation resources to distribution networks. Among available types of DGS, fuel cells show particular promise...
