新的贝叶斯DSSE方法使用流匹配改进电网状态估计

作者 PulseAugur 编辑部 · [1 个来源] · 2026-11-02 05:00

研究人员开发了一种新颖的贝叶斯配电系统状态估计（DSSE）方法，称为PoSE，它利用流匹配来学习变电站注入的分布。与简化先验的传统方法或特定测量集相关的深度学习方法不同，PoSE保持了贝叶斯结构，并且仅学习未知的系统参数。潮流方程、电网拓扑和测量通过卡尔曼型校正集成在采样过程中，确保每个后验样本代表一个物理上一致的工作点。这种方法提供了可靠的不确定性量化，并在IEEE 33节点馈线和Iowa馈线上都显示出更高的准确性，在概率注入误差、电压和支路电流误差方面优于现有方法。 AI

影响这种新方法通过提供更好的状态估计和不确定性量化，可以提高电力系统的准确性和可靠性。

Bayesian Distribution System State Estimation with Flow Matching

arXiv:2610.40728v1 Announce Type: new Abstract: Medium-voltage feeders have few real-time measurements, so distribution system state estimation (DSSE) rests on pseudo-measurements of the secondary substations, a prior in Bayesian terms. Weighted least squares keeps the power flow…
