  3. Abstract:
  4. Due to the liberalization of the electricity market and the introduction of distributed generation (DG), the importance of distribution loss allocation (LA) has increased. This paper presents a new method for distribution power LA in radial systems. The proposed method, which is based on the results of power flow and considers active and reactive power flows of lines for LA, is composed of three steps. In the first step, starting from the source nodes (i.e., the nodes whose generation is more than their load), the power loss allocated to all nodes is calculated and then the power loss allocated to the loads connected to each node is obtained. In the next step, the total power loss is allocated to the nodes in order to calculate the power loss allocated to the DGs based on the results of this step. In contrast to the previous step, in this step, allocating power losses to the nodes starts from sink nodes, which are the nodes whose load is more than their generation. In the final step, normalization is executed. The application of the proposed method is illustrated on two distribution feeders, and the results are compared with other methods
