A line loss approximation via parametrization is developed to improve performance of the simplified Baran and Wu DistFlow method, while maintaining a linear set of equations. The approach is evaluated on thousands of training feeders that are created to determine a numerically optimal setting for the parameterization. Feeders are generated using recent advances in synthetic network test case generation. The problem is formulated with the same structure as the simplified DistFlow, yet is more accurate given that line losses are explicitly expressed and quantified. The single-phase methodology is extended to multiphase systems by formulating matrix-vector equations that maintain an analogy to their single-phase counterpart. Results with approximated line losses are shown to also improve the accuracy of multiphase distribution system calculations.

单相和多相径向馈线的有损 DistFlow 公式

开发了通过参数化的线损近似以提高简化的 Baran 和 Wu DistFlow 方法的性能,同时保持线性方程组。该方法在数千个训练馈线上进行评估,这些训练馈线被创建以确定参数化的数值最佳设置。馈线是使用合成网络测试用例生成方面的最新进展生成的。该问题采用与简化的 DistFlow 相同的结构来表述,但鉴于线路损耗被明确表达和量化,因此更加准确。通过制定矩阵向量方程,将单相方法扩展到多相系统,该方程与单相对应物保持类比。显示近似线损的结果也提高了多相配电系统计算的准确性。
