Comprehensive Benefits Evaluation of Renewable Energy Based on Grey-DEMATEL and DQ-GRA
Abstract
In the pursuit of the ‘double carbon’ goal, the vigorous development of renewable energy has been an inevitable trend in energy transformation. The evaluation on comprehensive benefits associated with renewable energy plans is crucial for the advancement and implementation of renewable energy. This paper constructed an appraisal index system from four main dimensions, including economic benefits, environmental benefits, energy consumption benefits, and social benefits. This paper also proposed a hybrid multi-criteria decision-making (MCDM) model based on grey decision-making trial and evaluation laboratory (grey-DEMATEL) and modified difference-quotient grey relational analysis (DQ-GRA). Firstly, we applied the grey-DEMATEL to calculate the indicator weights used in modified DQ-GRA. Then, to rank renewable energy plans for evaluation, the proposed modified DQ-GRA method was applied. Finally, utilizing ten distinct renewable energy plans in Fujian Province as the focal point of our investigation, we undertook a comprehensive evaluation and analysis employing the research methodology introduced in this paper and compared the proposed method with the entropy weight method to authenticate its efficacy, thus validating the reliability and accuracy of our approach.
