- The purpose of this study is to assess the performance of wind power coupling hydrogen storage projects from the perspective of sustainability. Firstly, an evaluation criteria system for sustainability performance assessment is established, which includes economic, environmental and social aspects. Then, the criteria performances of each alternative are determined by expert groups in the fields of energy economy, energy environment and society sciences. Later, considering the uncertainty in the decision-making, the interval type-2 fuzzy Analytic Hierarchy Process and the interval type-2 fuzzy Technique for Order Preference by Similarity to an Ideal Solution technique are employed to weight the criteria and sort the alternatives, respectively. Finally, a case study in Tibet autonomous, China is given to illustrate the effective of the proposed evaluation criteria and technique. The result shows the alternatives A4 gets the highest score. Moreover, the results of sensitivity analysis reveal that the alternative A4 always secures its top ranking when its weight is floating within a certain range. Meanwhile, the weight results show that the criteria of levelized cost of energy and poverty alleviation promotion should gain more attention. This research can offer references for investors to make investment decisions and for the government to make corresponding policies.
