Resilient Microgrid Scheduling With Secure Frequency and Voltage Transient Response

The resilient operation of microgrids (MGs) relies strongly on their ability to operate in islanded mode, autonomously from the bulk grid, whilst adhering secure requirements. Catastrophic events transmission grid can lead abrupt MG islanding accommodated by large frequency and voltage excursions due power imbalances within MG. It is vital that scheduling algorithms incorporate both static transient security metrics ensure a transition during islanding, immunised against phenomena. In this paper, we frequency- voltage-related constraints operational planning problem robust events. We employ an iterative dynamic optimization approach, based sensitivities active reactive injections system metrics, problem. Due non-linear intractable nature, are reformulated as linear sequential resilience cuts resulting computationally efficient performance algorithm shown 30-bus, 20 kV, distribution network, subject 24-hour variation load renewable generation.
