为促进居民柔性负荷在需求响应中的规模化应用,可通过负荷聚合商对其进行聚合后调度.本文在考虑柔性负荷参与度基础上,提出了居民需求响应优化调度策略.首先,结合电动汽车、空调、洗碗机等柔性负荷运行特性,并将其视为虚拟储能以确定负荷参与度,进而用于计算用户补偿价格.其次,以负荷典型运行状态和行为特征作为聚类质心,采用K-means算法对柔性负荷进行聚类.最后,基于准线型需求响应机制,对所聚合负荷实施优化调度.仿真结果表明,所提出的需求响应方法可有效减小负荷峰谷差,提升负荷管理效果.
Optimal dispatching strategy for residential demand response considering load participation
To facilitate the coordinated and large-scale participation of residential flexible loads in demand response(DR),a load aggregator(LA)can integrate these loads for scheduling.In this study,a residential DR optimization scheduling strategy was formulated considering the participation of flexible loads in DR.First,based on the operational characteristics of flexible loads such as electric vehicles,air conditioners,and dishwashers,their DR participation,the base to calculate the compensation price to users,was determined by considering these loads as virtual energy storage.It was quantified based on the state of virtual energy storage during each time slot.Second,flexible loads were clustered using the K-means algorithm,considering the typical operational and behavioral characteristics as the cluster centroid.Finally,the LA scheduling strategy was implemented by introducing a DR mechanism based on the directrix load.The simulation results demonstrate that the proposed DR approach can effectively reduce peak loads and fill valleys,thereby improving the load management performance.
