Sustainable development of an area is highly dependable on reliable electrical energy supply. Due to the depletion of fossil fuels, and the contamination of the environment due to the generation of energy from primary energy sources, the energy sector is reforming and shifting towards a new era where renewable energy sources will become the primary focus of attention. At present, energy researchers and government organizations are interested in a distributed generation system using local renewable energy sources to electrify the rural areas situated far away from our mainland. Here, a biomass-based power supply system is being analyzed and compared with other potential power supply systems for Sagar Island. Sagar Island is the world’s largest river-based island situated in the Sundarban deltaic complex, where the potential of biomass is huge due to the availability of natural forests, barren coastal areas full of weeds, agricultural by-products, cattle manure and waste materials from other sources. Here, an attempt has been made to provide sustainable electrical energy to the rural areas of the isolated Sagar Island for the sustainable development of the local people. This was done by means of using biomass and a fuel cell based electricity generation system.

This paper presents an originally-developed system for design and optimization of AC-DC converters dedicated in particular to operation in distributed generation systems. The proposed procedure is based on a multi-objective discrete optimization and expert knowledge of electrical engineering, especially power electronics. The required accuracy of calculations is obtained by using the database with real components, while the parameters applied in calculations are based on parameters provided by the manufacturer. The paper presents the foundations and basic system properties, the design and optimization process, and selected optimization results, obtained with a fully functional prototype of the design and optimization system (DaOS).

W systemie elektroenergetycznym moc odbierana powinna być zbilansowana mocą wytwarzaną. Moc wytwarzana może pochodzie z aktualnie pracujących źródeł konwencjonalnych i niekonwencjonalnych oraz z zainstalowanych zasobników energii. W referacie przeanalizowano możliwość magazynowania energii w różnych zasobnikach. Analiza ta uwzględnia możliwość magazynowania rozproszonego i scentralizowanego. Metody porównano pod kątem wad i zalet.

Power of load should be balanced by the produced power. Production of power takes the place in conventional and unconventional energy sources and in installed energy storages. The paper presents analysis of possibility of different energy storages. Analysis takes into consideration distributed and centrally installed energy storages and their advantages and disadvantages.
