Frequency-Constrained Resilient Scheduling of Microgrid: A Distributionally Robust Approach

In order to prevent the potential frequency instability due high Power Electronics (PE) penetration under an unintentional islanding event, this paper presents a novel microgrid scheduling approach which includes system dynamics as well uncertainty associated with renewable energy resources and load. Synthetic Inertia (SI) control is applied regulating active power output of Inverter-Based Generators (IBGs) support post-islanding evaluation. The noncritical load shedding explicitly modeled based on distributionally robust formulation ensure resilient operation during events. resulted constraints are derived analytically reformulated into Second-Order Cone (SOC) form, further incorporated model, enabling optimal services provision from micorgrid perspective. With SOC relaxation AC flow constraints, overall problem constructed mixed-integer Programming (MISOCP). effectiveness proposed model demonstrated modified IEEE 14-bus system.
