考虑一个系统运营商，它希望随着时间的推移优化其目标，受操作约束以及由聚合器管理的可控负载的私有约束。在本文中，我们设计了一个实时反馈信号，以量化聚合器的可用灵活性，并将其传达给系统操作员。每次建议的反馈信号是操作员决策将启用的未来可行轨迹的条件概率。我们证明，正是这种唯一的分布使系统容量最大化以获得灵活性。它允许系统操作员在优化其目标的同时保持可行性并增强未来的灵活性。我们举例说明了该设计如何被系统操作员用来执行在线成本最小化和实时容量估计，同时可证明满足负荷的私有约束。
Consider a system operator that wishes to optimize its objectives over time subject to operational constraints as well as private constraints of controllable loads managed by an aggregator. In this paper, we design a real-time feedback signal for the aggregator to quantify and communicate its available flexibility to the system operator. The proposed feedback signal at each time is the conditional probability of future feasible trajectories that will be enabled by the operator's decision. We show that it is the unique distribution that maximizes a system capacity for flexibility. It allows the system operator to maintain feasibility and enhance future flexibility while optimizing its objectives. We illustrate how the design can be used by the system operator to perform online cost minimization and real-time capacity estimation, while provably satisfying the private constraints of the loads.
