The load control program in China is implemented with reference to the past power consumption ratio， without considering the energy efficiency of each subscriber. The important subscribers and the energy-intensive subscribers are not differentiated when implementing the restriction of power consumption. In light of this problem， a two-stage management scheme is proposed. At the first stage， the yardstick competition is applied in the optimal electricity energy rationing model to realize maximum energy consumption efficiency. At the second stage， the objective of the model is to obtain the maximum of energy consumption efficiency and the minimization of the switch operation time， the loss of the priority load as well as the interruptible load. The optimization management model considering the interruptible load is developed， and the combined heuristic NSGA-Ⅱ algorithm is employed with the gene correction module. Finally， the feasibility and effectiveness of the proposed method is proved by the research results.
