Abstract
Power flow analysis and power loss allocation are essential tasks in the operation and planning of radial distribution systems, especially in the presence of distributed generation. Conventional transmission-oriented power flow methods often face convergence and accuracy issues when applied to distribution networks due to radial topology, high R/X ratios, and bidirectional power flows. In addition, loss allocation is commonly treated as a separate post-processing step rather than being inherently integrated into the power flow formulation. This paper proposes a direct power flow algorithm with a self-adjusted loss allocation mechanism for radial distribution systems. By introducing virtual power variables, the nonlinear lossy power flow problem is reformulated into a lossless-equivalent model, enabling efficient and numerically stable matrix-based computations. The proposed approach inherently captures and allocates power losses to system participants without additional calculations. Simulation results on several standard radial distribution test systems demonstrate close agreement with Newton–Raphson power flow solutions. Furthermore, loss allocation results are validated against the branch current decomposition and superposition-based methods, confirming the accuracy and physical consistency of the proposed framework.
