The Electricity Directive (2019) introduced the responsibility for DSOs to develop distribution network development plans (DNDPs) that identify medium- and long-term planned investments and flexibility needs over the next five to ten years. Distribution networks must transform into modern and. This study outlines an approach for the automated distribution system planning that can calculate network reconfiguration, reinforcement and extension plans in a fully automated fashion. This allows the estimation of the expected cost in massive probabilistic simulations of large numbers of real. OVERLAY VS. The goal is to maintain safe, reliable, and affordable service while also efficiently operating the existing electrical facilities that make up the grid.
