Abstract—This study presents loss-reduction on radial electrical distribution system by reconfiguration based on optimum power flow pattern. A real section of distribution network from Istanbul is modeled according to actual load and network data. A new configuration is sought heuristically in order to minimize the interference on the optimum flow pattern. Reconfiguration is performed by closing all switches and consecutively opening the suitable switches carrying the minimum current until the radial system is acquired. Existing configuration and the meshed configuration with all switches closed are analyzed according to load flow calculations. A new network configuration satisfying the voltage and current limitations of the system with reduced losses is proposed for the system.
