Evaluation method for urban renewable energy utilisation efficiency based on DEA model

摘要

In order to overcome the low accuracy of urban energy efficiency evaluation, a method of urban renewable energy efficiency evaluation based on DEA model was proposed. Based on the principles of representativeness, comparability, feasibility and DPSIR model, the evaluation index system of urban renewable energy efficiency was constructed. The Analytic Hierarchy Process (AHP) is introduced to screen the indicators. The primary indicators are mainly composed of economy, physics and synthesis. The secondary index mainly consists of elastic coefficient of energy consumption and comprehensive utilisation rate of waste. Based on the evaluation index system, DEA is introduced to construct the evaluation model by taking the city as a decision-making unit DMU, so as to realise the evaluation of urban renewable energy use efficiency. The experimental results show that the evaluation results of the proposed method are closer to the actual situation than the literature results, and the fitting degree is more than 90%.
