Abstract: Aiming at the problems of large error and long evaluation time in power customer energy efficiency evaluation, this paper designs a demand-side response based power customer energy efficiency evaluation method. Firstly, determine the composition of energy efficiency equipment of power customers, as well as the primary and secondary indicators of power energy efficiency evaluation, and build an energy efficiency evaluation system. Secondly, complete the screening of energy efficiency evaluation indicators for power customers through multi-indicator analysis. Then, determine the cost curve change trend of power customer demand-side response, set the power balance constraints in power customer energy efficiency, build the power customer energy efficiency evaluation model of demand-side response, and complete the power customer energy efficiency evaluation. The test results show that the time cost of the proposed method is short, and the evaluation error is significantly reduced, and the maximum evaluation error is less than 0.5%.

Keywords: power customer energy efficiency; demand side response; first-level indicators; power factor; weighted average; balance constraint.
