A Novel Comprehensive Evaluation for the Performance of Energy Saving and Emission Reduction in Thermal Power Enterprise Based on Combination Weights and Improved Matter-Element Extension Model

Abstract:

As an important energy production and consumption area, the energy saving and emission reduction performance of thermal power enterprises relates to energy conservation and sustainable development of China’s economy. According to the energy saving policies of power industry, a comprehensive evaluation index system of energy saving and emission reduction performance was built, which contains of energy resource consumption, resource utilization, pollutants emissions and build business efficiency four aspects. The index weights were performed by AHP-entropy weight method considering the expertise and objective information. Meanwhile, an improved Matter-element Extension model was built to evaluate the energy saving and emission reduction performance of thermal power enterprise, in which the domain and standards of maximum degree in traditional model was improved. And an improved correlation function was proposed to instead of traditional correlation function, which is based on both maximum membership degree principle and closeness principles. Finally, the numerical results validate the effectiveness and practicality of the improved model.
