Optimization Of Mesh Network Configuration For Reduction Of Short Circuit Currents

Abstract

This paper deals with LV mesh network reconfiguration in order to minimize short circuitcurrents. The reconfiguration rests in switching off selected network elements leading to increase ofshort circuit impedances in LV nodes. For optimal configuration, an algorithm of sequential disconnectingof elements is proposed, based on load flow and short circuit calculations. The reconfigurationprocedure is applied to a model of a mesh MV/LV network. Reduction of short circuit currentsin this network is presented, capturing impact of each step of the sequence. Based on the presentedresults, deploying other measures and further development of the proposed algorithm are discussed.
