In 2011, the Federal Energy Regulatory Commission (FERC) mandated that demand response (DR) procurement pass a net benefits test (NBT) in Order 745 to ensure that the benefits outweighed the costs. Without NBT, DR procurement could result in losses to consumers considering payments for energy and DR services. Current NBT implementations are monthly. However, this neglects to consider two important issues: (a) generator supply curve and demand changes on an hourly basis thus altering the maximum DR quantity that can be dispatched considering NBT; and (b) system-wide implementations don't consider locational marginal prices, line flow limits, and network congestion. Both of these issues can severely distort proper implementation of the NBT. However, FERC allowed the NBT be applied monthly and system-wide in recognition of computational difficulties and lack of methods, and FERC called for research in real-time implementations of NBT. Our work responds to this call. To address these two shortcomings, we propose a new optimal power flow (OPF) formulation in which NBT is implemented into a real-time or near real-time dispatch OPF model and considers the network model in its entirety. Our proposed methodology is applied to a 4-bus test system, a 118-bus modified IEEE system, and a real Ontario system. We demonstrate that the embedding of NBT into real-time OPF formulation yields maximum benefits to remaining consumers when compared to conventional DR formulations.

将需求响应的净收益测试集成到最佳潮流公式中

2011年,联邦能源管理委员会(FERC)要求需求响应(DR)采购必须通过745号令的净收益测试(NBT),以确保收益超过成本。如果没有NBT,则灾难恢复采购可能会导致考虑向能源和灾难恢复服务付款的消费者蒙受损失。当前的NBT实施是每月一次。但是,这忽略了两个重要问题:(a)发电机的供应曲线和需求按小时变化,从而改变了考虑NBT可以调度的最大DR数量;(b)系统范围内的实现不考虑地理位置的边际价格,线路流量限制和网络拥堵。这两个问题都会严重扭曲NBT的正确实施。然而,FERC允许NBT在整个系统范围内每月应用一次,以认识到计算上的困难和方法的缺乏,FERC呼吁研究NBT的实时实施。我们的工作回应了这个呼吁。为了解决这两个缺点,我们提出了一种新的最优潮流(OPF)公式,其中将NBT实施为实时或接近实时的调度OPF模型,并全面考虑了网络模型。我们提出的方法论被应用于4总线测试系统,118总线修改的IEEE系统和实际的安大略系统。我们证明,与传统的DR配方相比,将NBT嵌入实时OPF配方可为其余消费者带来最大利益。为了解决这两个缺点,我们提出了一种新的最优潮流(OPF)公式,其中将NBT实施为实时或接近实时的调度OPF模型,并全面考虑了网络模型。我们提出的方法论被应用于4总线测试系统,118总线修改的IEEE系统和实际的安大略系统。我们证明,与传统的DR配方相比,将NBT嵌入实时OPF配方可为其余消费者带来最大利益。为了解决这两个缺点,我们提出了一种新的最优潮流(OPF)公式,其中将NBT实施为实时或接近实时的调度OPF模型,并全面考虑了网络模型。我们提出的方法论被应用于4总线测试系统,118总线修改的IEEE系统和实际的安大略系统。我们证明,与传统的DR配方相比,将NBT嵌入实时OPF配方可为其余消费者带来最大利益。
