Optimal Location Selection of Wind-Seawater Pumped Storage Plant via Internal Type-2 Trapezoidal Fuzzy Numbers Based VIKOR Model

For realizing sustainable development, energy conversion and management has reached a crucial stage. Considering the types of resources in coastal areas, this paper studies the location selection of the joint generation type of renewable energy as wind power and seawater pumped storage (SPS) plant. Firstly, critical location selection criteria are identified through national energy association (NEA) and expert meeting. Secondly, an improved multi-criteria decision making (MCDM) is proposed. Considering the fuzziness of qualitative criteria and the integrity of information in decision making process, the internal type-2 trapezoidal fuzzy numbers (IT2TrFNs) combining with VIKOR method are utilized to sort the optimal potential site. Finally a case study is introduced. The potential SPS station published in NEA will be used in the case as alternative sites for exploring optimal wind-SPS smart grid via fuzzy comprehensive MCDM mode. In addition, the site selection of coastal wind-SPS projects has not been discussed and paid much attention yet. Therefore, this study expands the knowledge and contributes to the literature.
