In recent years, significant research efforts have been devoted to the optimal planning of power systems. Substation Expansion Planning (SEP) as a sub-system of power system planning consists of finding the most economical solution with the optimal location and size of future substations and/or feeders to meet the future demand. The large number of design variables, and combination of discrete ...

This article proposes a framework that uses analytical assessment of reliability to guide the expansion planning power distribution systems (PDS) considering criteria. The allows estimation indices with and without execution projects, thus supporting decision-making process on investments in projects. In reliability, failure rates zones restoration times are calculated from past data interrupti...
