An innovative disjunctive model for value-based bulk transmission expansion planning

This paper presents an innovative modeling approach for multi-stage transmission network expansion planning (TNEP) optimization problem. It efficiently extends the traditional disjunctive model to allow multiple parallel circuit additions between two buses, by using a decimal-binary transformation mechanism. Case study results indicate that this method may significantly improve computational efficiency, particularly for multi-stage bulk transmission system planning optimization with high renewable penetration level, which usually considers building multiple parallel circuits for significant number of candidate route.
