Evaluation of Wind Power Plant Potentials in the Marmara Region, Turkey via TOPSIS and PROMETHEE Methods

Today, the use of renewable energy sources is increasing day by day. The essential advantages of wind energy are that it is clean, low costly, and unlimited. The efficiency of wind power plants is an important issue. In this paper, the wind energy potential of provinces of the Marmara region in Turkey was evaluated by multi-criteria decision-making (MCDM) methods. TOPSIS and PROMETHEE methods were used for analysis. The weights of the criteria determined for the decision model were taken equally. According to the analysis results, Balikesir and Çanakkale were determined as priority provinces in wind power plant potential, while Kocaeli and Sakarya were ranked last. Spearman's Correlation Coefficient determined the level and direction of the relationship between the rankings obtained from TOPSIS and the PROMETHEE method. It was concluded that the relationship between the obtained value of "0.636" and the rankings obtained from the methods was a "positive" and "moderate" relationship. In this context, it has been verified that two methods with different algorithm steps support each other.
