Abstract
The selection of a desirable site for constructing a pumped hydro energy storage plant (PHESP) plays a vital important role in the whole life cycle. However, little research has been done on the site selection of PHESP, which affects the rapid development of PHESP. Therefore, this paper aims to select the most ideal PHESP site from numerous candidate alternatives using the multi-criteria decision-making (MCDM) technique. Firstly, a comprehensive evaluation criteria system is established for the first time. Then, considering quantitative and qualitative criteria coexist in this system, multiple types of representations, including crisp numerical values (CNVs), triangular intuitionistic fuzzy numbers (TIFNs), and 2-dimension uncertain linguistic variables (2DULVs), are employed to deal with heterogeneous criteria information. To determine the weight of criteria and fully take the preference of the decision makers (DMs) into account, the analytic hierarchy process (AHP) method is applied for criteria weighting. After that, an extended Vlsekriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method is utilized to provide compromise solutions for the PHESP site considering such heterogeneous information. At last, the proposed model is then applied in a case study of Zhejiang province, China to illustrate its practicality and efficiency. The result shows the Changlongshan should be selected as the optimal PHESP.

Summary
With the increasingly serious environmental pollution and aggravation of the global energy crisis, developing renewable energy vigorously has become an inevitable choice of mankind. At the same time, the phenomenon of power curtailment is becoming increasingly prominent since wind and solar energy are characterized by volatility and intermittency [1]. This kind of phenomenon has brought humans huge economic loss and restricted the development of renewable energy. A total of 47 potential PHESPs, with an installed capacity of more than 30 million kW, have been initially identified by local government. The total installed capacity of PHESPs in Zhejiang province is 458 million kW, including 308 million kW operating capacity and 150 kW under-constricting capacity.
