Wind Power Survey for Sustainable Development of Energy in Hamedan

The study of replacing fossil fuels with clean and renewable energies is growing over the world and exploitation of these sustainable energy sources is of special importance due to environmental necessities and diversify the sources of energy used. The present study aimed to determine wind energy potential and check if there are any possible optimal locations in order to exploit sustainable wind energy using statistics of synoptic stations in Hamadan province. In this study, initially, three-hour long-term data of wind speed and direction were evaluated using the synoptic stations statistics in Hamedan province during a five-year period. Then, Annual Wind Rose graph was drawn. After that, different distributions were tested for fitting wind data. Experimental probability of data was calculated using selected distribution. The results showed that in Hamedan station, Weibull and in Nojeh, Nahavand and Tuyserkan stations, inverse Gaussian distribution are the most accurate distributions in predicting the possibilities of wind speed. Also the wind power density at the maximum possible height for using wind power was calculated 15.24, 21.7, 10.8 and 6.3 watts per square meter in Hamadan, Nojeh, Skinheads and Tuyserkan stations respectively. According to the results, none of the obtained figures is desirable compared with the necessary standards for constructing wind power plants. Due to the number of wind blowing hours and necessary wind existence percentage between start and stop speeds of wind turbines, wind energy exploitation in of the surveyed stations is not cost-effective, therefore, they are not recommended
