Advanced Distribution Management System: Automation of Optimal Feeder Reconfiguration in Spindle Distribution Networks

This study aims to develop Optimal Feeder Reconfiguration using ADMS and SCADA technology for the spindle distribution network at Gandul Primary Substation, South Jakarta. Using DIgSILENT PowerFactory software, the Automation of OFR operates by detecting real-time load conditions and automatically reconfiguring feeders to support the Smart Grid, improve voltage quality, reduce losses, and maintain load balance during contingencies. As a result, the voltage at the JGK29 Distribution Substation increased from 19.8 kV to 20 kV and losses at Gandul Primary Substation were reduced by 14.2%, or 10.8 MWh from a total daily loss of 76.1 MWh. In the N-1 contingency simulation, OFR successfully reduced the load on Feeder Express Krukut from 250.7 A to 170.6 A by automatically switching to Feeder Besan and Buyut.
