Shortest Path Algorithm To Assess New Levers & Flexibilities In Long Term Sizing Distribution Networks

Currently, many distribution system operators (DSO) do not consider long-term planning (LTP) or carry it out based on a single deterministic scenario. This article studies the evolution of a distribution network (DN) facing multiple scenarios, according to different LTP approaches used by the DSO. The objective is to demonstrate the value of LTP for DSOs and to propose a probabilistic sizing approach, integrating uncertainties regarding the nominal powers of new users, and introducing the notion of constraint violation risk.
