This paper presents a two-stage microgrid scheduling strategy in which the frequency control reserve (FCR) is incorporated to ensure economic, reliable, and stable microgrid operation in a joint energy and ancillary service market environment. In addition, to using such reserve to limit frequency excursions caused by uncertainties of active loads and renewable generation, this paper is focused on determining the optimal provision of reserve for microgrid operation mode switching to assure sufficient reserve is available and readily deployable at the disposal of the microgrid operator. The scheduling problem is formulated as a two-stage chance-constrained programming (CCP) model where the power balance chance constraints are used to determine the trade-off between operational economy and stability risk exposure. The chance-constrained formulation is then approximated as a deterministic mixed-integer linear programming (MILP) model for solution. Two sets of policy studies are performed through simulation to evaluate the effectiveness of the proposed strategy in enhancing the operational performance of a microgrid through optimal scheduling.

包含频率控制储备的稳定性受约束的微电网调度

本文提出了一种两阶段的微电网调度策略，其中并入了频率控制储备（FCR）以确保在联合能源和辅助服务市场环境中微电网的经济，可靠和稳定运行。此外，为了利用这种储备来限制由有功负荷和可再生发电的不确定性引起的频率偏移，本文的重点是确定微电网运行模式切换的储备的最佳提供，以确保有足够的储备可随时用于处置微电网运营商。调度问题被表述为两阶段机会受限编程（CCP）模型，其中功率平衡机会约束用于确定运营经济性与稳定性风险之间的权衡。然后，将机会约束公式近似为确定性混合整数线性规划（MILP）模型以进行求解。通过仿真进行了两组策略研究，以评估所提出策略通过最佳调度来增强微电网的运行性能的有效性。
