Abstract :
AbstractFinding the best site for construction of wind farm such as any other engineering project needs basicinformation and specific programming. After confirmation of exploitable wind potential, finding thesuitable location of wind farm regarding to various technical, economic-social and natural factors areso important. This study analyzes land suitability for placing wind farm in Ardabil province regardingto some effective factors such as height, slope, and distance from urban areas, distance from villageregions, distance from water bodies and distance from main roads networks. For this purpose, at first 9effective factors are identified and prepared in GIS and weight of each criterion and classes arecalculated by Analytic Hierarchy Process (AHP) and Simple Additive Weighting (SAW) methods.The next step of procedure was the elimination of exclusionary areas for wind power plant.Afterwards, the study area was zoned for each criterion using analytical functions of GIS. Finally byintegrating zoned maps based on weight from AHP and SAW methods, final map of both methods aresupplied in 5 classes from completely suitable to unsuitable. In this study comparing the results of 2methods expressive that AHP method results are more cautious than SAW results. Also Completelysuitable class resulted from 2 methods in spite of different area, shows Ardabil Plain and foothills ofSabalan could be considered as suitable site to exploit of wind energy.
