Abstract

Based on the consideration of the system primary energy utilization and renewable energy consumption, the energy efficiency evaluation indices of multi-energy system of an industrial park is proposed. The weight of each index is determined by the information entropy principle, and the comprehensive energy efficiency evaluation index and evaluation method of the multi-energy system of industrial park are also established. Considering the change of energy demand in typical days of summer, winter and transition season, the two operating strategies of “Electric Load Following” and “Thermal Load Following” are used to simulate multiple system operating scenarios. Based on the established index system, the comprehensive energy efficiency of each scenario is calculated and its comprehensive energy efficiency is evaluated for an industrial park in Beijing. The case study shows that the comprehensive evaluation model and evaluation method of energy efficiency can fully reflect the characteristics of multi-energy complementary operation and cascading energy utilization in the park, which has practical significance for the design and operation of multi-energy system.
