Application of TLBO for Distribution Network Planning via Coordination of Distributed Generation and Network Reconfiguration

Abstract

This paper proposes an application of Teaching Learning Based Optimization (TLBO) method for optimal integration of Distributed Generations (DGs) in distribution systems to minimize annual energy loss and to maintain a better node voltage profile using penalty factor approach. A piece-wise linear variable load pattern is considered and the distribution network is reconfigured after optimal DG placement. Efforts have been made to scan the search space efficiently in such a way that every node of the system is a candidate node for DG placement with a priority level. The proposed method is applied on IEEE 33-bus test distribution system. The results obtained are promising when compared with other recently established methods.
