Technical and economic analysis of different micropowers in providing network load and optimal selection with real load analysis of a 20KV/400V station in Bushehr Province of Iran

Increasing of the price of the fossil fuels and reducing them and their pollution, new clear energy have been more popular in the world but lack of notice to study of economic efficiently on new energy (NE) cause to inefficiency and inappropriate to use of these energies then leads the consumers to use the same fossil fuels. Some consumer need their electrical energy be supplied Such as hospital, military base, etc. therefore this is useful that, all or part of their electrical energy requirement be supplied to they don´t sense any shortage of electrical energy. So in this paper is tried to analyses various and popular micropower that can be connected to grid with homer software. This paper with attention to actual demand of loads and climate of Bushehr province have been compared various popular micropower together technically, economically and environmentally and at the end select the best choice with these properties of Bushehr loads and Bushehr climate.
