Abstract: The aim of this paper is to introduce the demand re-allocation process (demand estimation) in conjunction with feeder input complex power for Unbalanced Radial Distribution System (URDS) with mutual impedances using Iterative Power Flows (IPFS) method. The proposed method in this paper is to compute the individual loads on each phase in conjunction with the feeder telemetered complex power input and with the help of backward forward sweep power flow method calculate iteratively nodal voltages and total losses per phase on the feeder. The practical 8 bus and 55 bus unbalanced radial distribution systems with mutual impedances are used to describe the novelty of the proposed algorithm. The simulation results in terms of new individual demands, bus voltages and total per phase losses are summarized. The bus voltages with iterative power flows method are compared with direct approach power flow method results.
