Techno-Economic Evaluation of a Distributed Generation Based on Renewable Energy Sources

This paper presents an optimization based approach in order to achieve an acceptable Total Cost of Electricity (TCE). To reduce the TCE of the system which contains a PV/Wind sub-system and a battery, the conventional Genetic Algorithm (GA) based approach is used. The continuity of service requires the substitution of the production source overnight by the association of a lead-acid battery under the global system in order to control the output power by meeting the needs of consumers. By introducing the TCE as important factor, an economic evaluation is elaborated by presenting an acceptable cost of energy. The results obtained show a high level of economic feasibility by achieving a lowest TCE.
