摘　　要：需求响应是调节用户负荷的重要手段,通过削峰填谷可以有效削减系统的高峰负荷,进而接纳更多的用户进入系统,为此有必要开展考虑需求响应的馈线可开放容量评估研究。分析不同类型的需求响应对馈线可开放容量的影响;根据不同需求响应的实施机制,建立以用户收益最大为目标的响应模型;基于馈线分段转供,综合考虑需求响应及实际负荷分布,建立馈线可开放容量评估模型;根据算例对比分析不同类型的需求响应对可开放容量的影响及作用机理。结果表明考虑需求响应可以有效降低系统在负荷高峰时的备用容量和N-1故障时的负荷转供压力,充分挖掘馈线的可开放容量。Demand response is an important means to adjust user load.The peak load of system can be reduced and more users can be accepted by peak load shifting.Therefore,it is necessary to carry out the research on evaluation of feeder available capacity considering demand response.The influence of different demand responses on feeder available capacity is analyzed.The response model is established according to different demand response implementation mechanisms,which aims to maximize the user’s benefit.Then,based on feeder section transfer,the evaluation model of feeder available capacity is established by taking the demand response and actual load distribution into consideration comprehensively.The influence of different demand responses on available capacity and its mechanism are compared and analyzed according to the example.Results show that when considering demand response,reserve capacity of system at peak load time and load switching pressure during N-1 failure can be effectively reduced,and feeder available capacity can be fully exploited.
