Linear Power Flow Calculation Method for Distribution Network Considering Branch Power Loss

There are many low-voltage distribution networks with complex lines. In order to improve the speed of power flow calculation and ensure the accuracy of calculation, based on the traditional nonlinear power flow calculation model of distribution network, a power linear flow calculation method considering the active and reactive power loss of branches is proposed. No iteration is required in the process of this calculation method. The effectiveness of the proposed method is verified by comparing the power flow calculation results of the proposed method and the forward and backward substitution method in a standard IEEE33 node distribution network test system.
