摘　　要：以电器用电效用等级划分为基础,结合遗传算法对电力需求侧进行需求响应调度,可以在保障用户用电满意度的前提下,实现自动实时响应削峰目标。首先给出生活电器用电效用的定义、效用函数以及效用分级方法;在此基础上,给出削峰调度模型,并给出调度流程与算法分析;最后,模拟办公楼内空调的需求响应调度。结果表明,优化控制策略可以在保障用户用电满意度的前提下,实现自动实时响应削峰目标,从而论证了方法的有效性。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.
