Power flow tracing is the most effective method for the fair apportioning the transmission losses to the users of the restructured power systems. In this study, a simple method is proposed to trace the active power flows. In the proposed method, for a given operating point obtained by the AC load flow, the so‐called injection‐bus and extraction‐bus matrices are formed for the system. By using the properties of these matrices, three other matrices are derived, which allow the active power production of the generators to be expressed in terms of the active power consumption of the loads, and vice versa. These matrices provide the opportunity to determine the contribution of each generator to active loss of each branch and active power consumed by each load as well as to allocate the active loss of each branch to each load. Implementation of this method on several systems with different topologies and sizes show that it can provide acceptable and reasonable results for loss allocation problem in a short time.
