RNR: Reliability oriented Network Restructuring

Abstract

This paper presents the reliability indicators for power system restructuring. A reliability oriented network restructuring (RNR) mathematical formulation is proposed for solving power grid expansion decision with non-linear AC-OPF. The microgrid structures are derived from the standard IEEE 14 bus system architecture. The proposed reliability framework is implemented with the set of reliability indicators for measuring the system performance. The model was solved using outer approximation algorithm. The analysis is conducted to investigate the importance of restructuring in an investment decision for the expansion. The results with a comparison between investment and investment with restructuring are outlined. Consequently the expansion considering the restructuring is found to be practical and feasible.
