On the basis of the level of electrical appliance utility,and in combination w ith the genetic algorithm,w e conduct demand response dispatch on the demand side of pow er system,w hich can achieve the goal of peak load shifting in automatic real-time response on the premise of ensuring electric consumers＇ satisfaction. Firstly,w e present the definition,utility function and utility grading methods of life electrical appliances. On this basis,w e introduce the peak load shifting dispatch model,the dispatch process and the algorithm analysis. Finally,through simulating the demand response dispatch of air-conditionings in office buildings,it is proved that the load peak shifting target of the automatic real-time response can be realized on the premise that customers＇ satisfaction tow ards electricity supply is guaranteed,w hich can demonstrate the effectiveness of the method.
