A Resilience Management Method for Power Outages with Dynamic Prioritization of Consumer Resources

To address power outages, cooperative utilization of consumer-side resources through power sharing and exchange is expected to enhance resilience. In our previous study, we proposed the multilevel resource priority management method that considers the use of individual resources and incorporates load suppression. Building on this foundation, this study proposes an extended resilience management method that dynamically prioritizes consumer resources based on the state of consumer resilience. In this method, the tradeoff between consumer priority and mutual-support priority is defined as a multistage dynamical priority management model and formulated as a mixed-integer linear programming optimization problem. As a numerical example, the simulation of a consumer model with 512 households representing the size of one feeder in a distribution system was conducted. Furthermore, an equality index was introduced to assess variations in resilience services between each consumer. Consequently, the relationship between the priority management model, cooperative group size, and equality index was clarified.
