摘      要：Urban energy systems(UESs)play a pivotal role in the consumption of clean energy and the promotion of energy cascade *** the context of the construction and operation strategy of UESs with multiple complementary energy resources,a comprehensive assessment of the energy efficiency is of paramount ***,a multi-dimensional evaluation system with four primary indexes of energy utilization,environmental protection,system operation,and economic efficiency and 21 secondary indexes is constructed to comprehensively portray the *** that the evaluation system may contain a large number of indexes and that there is overlapping information among them,an energy efficiency evaluation method based on data processing,dimensionality reduction,integration of combined weights,and gray correlation analysis is *** method can effectively reduce the number of calculations and improve the accuracy of energy efficiency ***,a demonstration project for a UES in China is *** energy efficiency of each scenario is assessed using six operational *** results show that Scenario 5,in which parks operate independently and investors build shared energy-storage equipment,has the best results and is best suited for green and low-carbon *** results of the comparative assessment methods show that the proposed method provides a good energy efficiency *** study provides a reference for the optimal planning,construction,and operation of UESs with multiple energy sources.
