摘　　要：为利用需求响应(demand response,DR)技术削减配电小区峰谷负荷差,改善负荷曲线,提出一种基于分时电价的智能家电管理控制方案。首先,针对各家电设备运行规律不同的特点,抽象出3种家电负荷类型,并建立对应类型的控制模型及DR策略;其次,按照分时时段对分时电价信息进行模糊化处理,得到电价优先级,针对DR事件(需求响应最大限制负荷、需求响应时间、可中断负荷时长等),引入DR控制规则和预调度机制;最后,对控制调度队列中家电的调度顺序进行切换和实施控制,以实现峰谷负荷的均衡。通过仿真算例对比分析了预调度与正常DR调度对电网负荷的均衡效果和经济效益,结果表明,控制方案能减少用户的整体费用支出和缓解电网负荷,因而是可行且合理的。To decrease the peak-valley difference and improve load curve in residential area by demand response （DR） technology, a time-of-use （TOU） pricing based control scheme for intelligent household appliances is proposed. Firstly, three types of household appliance loads are abstracted from different operation laws of various household appliances, and the control models and DR strategies corresponding to these types are established; secondly, the fuzzified processing for the information of TOU price which based on the time intervals is performed to achieve the price priority, in accordance with such DR events as the maximum restricted load of DR, the time of DR and the duration of interruptible load and so on, the DR control rule and pre-scheduling mechanism are led in; finally, the dispatching sequence of household appliances in the control and scheduling queue are switched and controlled to implement the equilibrium of peak and valley loads. The equilibrium effects and economic benefits of power system by pre-scheduling and DR dispatching are compared and analyzed by simulation example, and the results show that using the proposed household appliance control （HAC） scheme the overall cost of consumers can be reduced and the power system load can be aUeviated, so the proposed household appliance control （HAC） scheme is feasible and reasonable.
