Recently, along with the depletion of fossil fuels and growing electrical requirements, more attention has been paid on utilizing Renewable Energy Sources (RESs). The Chichest tourism complex is located 20 km far from Orumieh, Iran which has been supplied through the main distribution grid connection. But, recently the trend is to expand the share of RESs in supplying microgrids demand. Hence, this study reports the optimum investment planning for electrical expansion of grid-connected Chichest tourism complex including diesel/wind/PV/battery technologies. For the optimal planning of microgrid, an efficient simply-computational two-stage procedure is proposed. In the first stage, all of the feasible system configurations are determined using NREL’s HOMER software which is a well-known and well-established optimal modeling environment. Subsequently, in the second stage based on Analytical Hierarchy Process (AHP) and simple additive weighting (SAW) method, the best configurations for hybrid system are determined through the Expert Choice software considering economical and environmental criteria. With the aim of providing a comprehensive decision-making capability, a sensitivity analysis is performed considering relative importance of criteria. Simulation results demonstrate that for Chichest coast, the best configuration is grid/diesel/wind hybrid system as it shows a uniform behavior for different cases.
