A Framework for Reliability Assessment in Expansion Planning of Power Distribution Systems

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 interruptions primary network. addition, estimated adjusted historical values through proportionate length each zone. To test validate proposed framework, it was applied network at bus 5 Roy Billinton Test System (RBTS) also real feeder located Brazil. results indicated can help define most attractive leading improvements reduction unsupplied energy. energy not supplied, considered following alternatives: (i) installation normally-closed sectionalizing switches, (ii) normally-open switches interconnection adjacent feeders, (iii) automation (iv) reconductoring Nevertheless, inclusion other alternatives. Finally, proved be handy useful for real-life applications.
