Many stand-alone diesel units are Supplied Rural and remote loads all around the world. With increases oil price, energy crisis, reduce fossil fuels in theworld and the concerns about global warming, the integration of diesel generators with renewable energy systems have become an attractive energy sourcesfor supplying the load demand. This paper performs an optimal design of integrated system involving Wind-PV-Diesel-Battery system for supply remote and rural powerdemand with CO2 emission evaluation by using PSO (Particle Swarm Optimization). The system components and radiation andwind speed datasets are assumed to be fully deterministic. System costs involve investments, operation and maintenance aswell as loss of load costs. Prices are all unfeigned and components are commercially available. Wind and radiation datasets are for northwest region (Jolfa,latitude: 38_56, longitude: 45_37, altitude: 710, m) of Iran. From simulation results the proposed system is able to minimize thetotal annual cost of the system under study and reduce CO2 emission generated by diesel generator.
