Value Assessment of Smart Control for Resilience-Oriented Planning of Urban Energy Systems

In recent years, frequent occurrences of high-impact, low-probability (HILP) events, such as typhoons, avalanches, and hurricanes, have inflicted significant damage on both the energy infrastructure and society as a whole. This has spurred energy system planners to explore strategies for enhancing resilience to effectively mitigate the impact of such events. This study proposes a resilience-oriented planning framework aimed at enhancing the resilience of multi-energy microgrids (MEMGs) in urban areas against HILP events. Within this framework, two control methods are introduced, namely preventive control and corrective control, which are analyzed and quantified through case studies. The findings underscore the importance of these control techniques in bolstering the resilience of urban energy systems against HILP events. Preventive control measures are shown to reduce load shedding and planning costs during disruptive events, while corrective control measures effectively minimize load shedding of essential loads and associated costs. These insights contribute to the economic and safety aspects of MEMGs' planning, thereby fostering greater resilience in urban energy systems.
