An algorithm for optimal phase balancing of secondary distribution systems at each node

In this paper, a phase balancing algorithm is developed to balance the load at each candidate node of the secondary distribution network from tail end of the feeder by rearranging the connections of consumer load/ service laterals. Phase balancing is a concept of re-phasing service laterals such that load on three phases is balanced. The algorithm is designed to handle three, two and single phase time varying loads with an objective of loss reduction and minimum number of phase moves. To evaluate the performance of proposed algorithm, it is applied to the IEEE 13 node test feeder. The simulation results confirm the efficiency of algorithm for reduction of power loss and phase balancing of secondary distribution network with minimum number of phase moves.
