Determination of optimal renewable energy growth strategies using SWOT analysis, hybrid MCDM methods, and game theory: A case study

Abstract

Summary Due to population growth and industrial development, Iran is facing the challenge of energy supply in various industrial, power plant, agricultural, and residential sectors. While most of Iran's energy supply comes from fossil fuels, these fuels have devastating environmental impacts. Therefore, Iran has to invest more in its renewable energy sources. Given that many locations of Iran have significant wind, solar, and geothermal potential, this study used a combination of SWOT, multicriteria decision‐making approaches, and game theory to identify the best renewable energy development plans for the country. The Stepwise Weight Assessment Ratio Analysis (SWARA) technique was applied to weight the criteria and sub‐criteria. Impact on the environment, resource potential, and power generation cost with weights of 0.218, 0.182, and 0.145 was recognized as the most important sub‐criteria, respectively. To rank the factors in each SWOT dimension, namely, strengths, weaknesses, opportunities, and threats, the Grey Additive Ratio ASsessment (ARAS‐Grey) method was then used. Using the game theory and fuzzy Shapley value, the best combination of renewable energy development strategies was determined to be SO1ST3WO1WT1 with a value of (1.72, 0.58, 0.3). The development of high‐efficiency wind and solar technologies and the minimization of output fluctuations and loss through energy storage methods such as hydrogen production and battery banks were identified as the best strategy combination for renewable energy development in Iran.

Machine Learning-Based Classification and Evaluation of Regional Ethnic Traditional Sports Tourism Resources

“…where r SB indicates the reliability indicator of the whole test after correction and r hh indicates the split-half reliability. SWOT analysis was introduced by Steiner, an American management professor, in the early 1980s and is one of the common methods of competitive intelligence analysis [28][29][30].…”

A new decision making method based on Z-decision-making trial and evaluation laboratory and ordered weighted average and its application in renewable energy source investment

“…The uncertainty of information in the RES investment decision process attributes to the subjectivity of domain experts and the complexity of the evaluation objects. The existing methods for dealing with uncertain information are fuzzy set theory (Bilgili et al, 2022;Van Thanh, 2022;Saraswat and Digalwar, 2021), grey theory (Wang C.-N. et al, 2021;Almutairi et al, 2022), Dempster-Shafer (D-S) evidence theory (Deng and Jiang, 2020;Xiong et al, 2021;Xiao, 2021), Dnumber theory (Deng and Jiang, 2019b,a), and Z-number theory (Rathore et al, 2021;Tian and Kang, 2020;Li et al, 2020;Jiang et al, 2020). Among them, Z-number can represent the uncertainty and the reliability of evaluating information simultaneously (Hu and Lin, 2022;Cheng et al, 2022;Tian et al, 2021;Meng et al, 2022b), which is superior in the modeling of uncertainties in RES investment.…”
