Hybrid Design of Electric Power Generation Systems Including Renewable Sources of Energy

With the stricter environmental regulations and diminishing fossil-fuel reserves, there is now higher emphasis on exploiting various renewable sources of energy. These alternative sources of energy are usually environmentally friendly and emit no pollutants. However, the capital investments for those renewable sources of energy are normally high, and there are also maintenance cost differences to be considered. Furthermore, due to the intermittency of some of these power sources, reliability issues should be addressed when integrating different power sources. In this article, as an example, the design of hybrid generating systems comprising wind turbine generators, photovoltaic panels, and storage batteries is discussed based on multidisciplinary optimization. In this multisource generation system design, three design objectives are considered, that is, system cost, reliability, and pollutant emissions.

Key Words: clean electric power • cost estimation • hybrid generation systems • multicriteria design • pollutant emissions • reliability • renewable sources of energy • sustainability
