Research on Network Loss Allocation Calculation Based on Arbitrary Segmentation

This paper has proposed a network loss allocation method on the basis of power flow tracing and improved average network loss coefficient based on arbitrary segmentation for power networks. This method improves the calculation efficiency of network loss allocation. Firstly, the power network is segmented into multiple regions based on the arbitrary segmentation method, and the nodal association matrix is used to equivalent individuals in the segmented regions. The power flow tracing method is used to allocate tie line loss between regions to each regional individual. Then, the improved average network loss coefficient method is used to calculate the network loss of independent individuals in each region. Finally, the simulation calculation for this method and the traditional network loss allocation method is implemented in IEEE 14 node system, and the simulation results verify the efficiency and accuracy of the method proposed in this paper.
