本文提出了一种能准确估计电压幅值的配电系统线性潮流模型。该模型可以看作是将LinDistFlow模型推广到任意线性化点周围具有一般网络拓扑（径向或网状）的多相配电系统。我们已经证明，当两者都在零注入点附近线性化时，所提出的模型的近似质量严格优于定点线性化（FPL）方法，定点线性化（FPL）方法是一种用于配电系统分析的常用线性潮流模型。给出了使用标准IEEE测试馈线的数值示例，以说明所提出模型的有效性，以及在非零注入点周围线性化时比现有方法精度的提高。
This paper proposes a new linear power flow model for distribution system with accurate voltage magnitude estimates. The new model can be seen as a generalization of LinDistFlow model to multiphase distribution system with generic network topology (radial or meshed) around arbitrary linearization point. We have shown that the approximation quality of the proposed model strictly dominates that of the fixed-point linearization (FPL) method, a popular linear power flow model for distribution system analysis, when both are linearized around zero injection point. Numerical examples using standard IEEE test feeders are provided to illustrate the effectiveness of the proposed model as well as the improvement in accuracy over existing methods when linearized around nonzero injection points.
