Abstract	Diesel power technology has been utilized worldwide , especially in remote regions, because of its low initial capital cost. But it has negative effects on the surrounding envi ro ment and causes global warming. Also the power s upply of off-grid remote area and applications at minimal cost and wi th low emissions is an important issue when discuss ing future energy concepts. In Iran, the cost of fuel is highly subsi dized. If Iran removes the fuel subsidy, the cost o f diesel fuel would increase and the renewable energy systems would bec ome more attractive. This paper presents techno-economic analysis, model ing and optimization of a photovoltaic (PV)/wind/di esel/batterybased hybrid system for electrification to an off-g rid remote area located in Rafsanjan, Iran, for dif ferent diesel generator fuel price scenarios. For this location, different hybrid (PV/wind/diesel/battery) systems a re studied and compared in terms of cost and pollution for two sce narios. For cost analysis, a mathematical model is introduced for each system's component and then, in order to satis fy the load demand in the most cost-effective way, two discrete versions of particle swarm optimization algorithm a re developed to optimally size the systems componen ts. As an efficient search method, PSO has simple concept, is easy to implement, can escape local optima, by use of probabilistic mechanisms, and only needs one initial solution to start its search. Simulation results indicate that only under a subsidized diesel fuel price scenario, the diesel-o nly system has the minimum cost, but by the elimina tio of diesel fuel price subsidies and reduce the costs of photovoltai c p nels and wind turbines, the role of the diesel generator decreases in hybrid (PV/wind/diesel/battery) energy systems.
