Abstract

Some efficient and accurate approximation formulas for the variations of line loss, bus voltages and branch currents caused by a switch operation are derived in this paper and then integrated into feeder reconfiguration problems. Two matrices developed from the topological structures of distribution systems are used to analyze the relationship between bus voltages, bus current injections and branch currents. Therefore, the: line loss, bus voltages and branch current caused by a switch operation can be approximated accurately and efficiently. The proposed formulas are then integrated into branch exchange algorithm and used to solve minimum loss reconfiguration. Test results compare the efficiency and accuracy of the proposed formulas.
