Abstract:

为利用需求响应(demandresponse,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。
