Resilience Assessment in Distribution Grids: A Complete Simulation Model

For several years, the increase of extreme meteorological events due to climate change, especially in unusual areas, has focused authorities and stakeholders attention on electric power systems’ resilience. In this context, authors have developed a simulation model for managing resilience electricity distribution grids with respect main threats which these infrastructures may be exposed (i.e., ice sleeves, heat waves, water bombs, floods, tree falls). The simulator identifies more vulnerable network assets by means probabilistic indexes, thus suggesting best corrective actions implemented improvement. fulfillment grid constraints, i.e., loading limits branches voltage buses, under actual operating conditions, is taken into account. Load scenarios extracted from available measurements are evaluated load flow analyses order choose, among solutions identified, those compatible constraints. proposed tool can assist Distribution System Operators (DSOs) drawing up Action Plan improve, one hand, and, other remove any possible limitation adoption ensure maximum operational continuity during weather events.
