本文应用最优潮流(OPF)来评估和最大化需求侧管理(DSM)的网络效益。收益是根据需求响应负载缓解上游网络限制和提供辅助服务(如运营备用)的能力来量化的。该研究纳入了有关负荷结构和组成的详细信息，并允许量化和比较通过管理不同负荷类型获得的潜在网络效益。分析表明，可管理负荷的实际网点位置对所采用的需求侧管理方案的有效性有重要影响，因为负荷及其互联网络的特性因地点不同而有所不同。因此，一些网络位置更有利于需求侧管理的实施，而最优潮流可以用于确定需求侧资源的最优分配。将时序最优潮流应用于典型的放射状和网状英国配电网，评估了该方法的有效性。分析结果表明，网络运营商不仅可以参与，而且可以鼓励和增值在最佳网络位置实施特定的需求侧管理方案，以实现需求侧管理的总收益最大化。
This paper applies optimal power flow (OPF) to evaluate and maximize network benefits of demand-side management (DSM). The benefits are quantified in terms of the ability of demand-responsive loads to relieve upstream network constraints and provide ancillary services, such as operating reserve. The study incorporates detailed information on the load structure and composition, and allows the potential network benefits, which could be obtained through management of different load types, to be quantified and compared. It is demonstrated that the actual network location of demand-manageable load has an important influence on the effectiveness of the applied DSM scheme, since the characteristics of the loads and their interconnecting networks vary from one location to another. Consequently, some network locations are more favorable for implementation of DSM, and OPF can be applied to determine the optimal allocation of demand-side resources. The effectiveness of the presented approach is assessed using a time-sequential OPF applied to typical radial and meshed U.K. distribution networks. The results of the analysis suggest that network operators could not just participate in, but also encourage and add value to the implementation of specific DSM schemes at the optimum network locations in order to maximize the total benefit from DSM.
