A Pathway to Mitigate Climate Change Impacts on Energy Communities: Decarbonization-Based Cost-Effective Grid Resilience Enhancement

Distribution systems starting from energy providers to end-users generally spread over a specific wide geographical area, resulting in more vulnerabilities to destructive weather-related (DWR) events. To effectively enhance grid resilience and accelerate decarbonization under a comprehensive resilience assessment, it is of paramount importance to apply efficient methodologies to characterize precise locations of distribution system components. Specifically, accurate models associated with informative distribution lines and system buses to investigate the behaviors of DWR events are still challenging and await to be solved. Therefore, a novel mesh-view structure is first proposed in this paper to determine the precise location of each distribution system component. Various types of DWR events under different severity levels are formulated to assess critical resilience metrics based on the mesh-view structure. A resilient and decarbonized pathway is further achieved by incorporating both the resilience and carbon emission indices into a judicious two-stage stochastic scheduling method, which enhances grid resilience and minimizes both operational costs and carbon emissions. To develop such a resilient, decarbonized, and cost-effective distribution system, with the interaction of the proposed mesh-view structure, distributed energy resources (DERs) are finally employed to identify and assess different behaviors of DWR events with respect to different allocations of DERs. A33-bus test case has been demonstrated to show the effectiveness and efficiency of the proposed mechanism.
