Node-Breaker Model of the IEEE 300-Bus System

Conventianlly, state estimation is run on reduced bus-branch (BB) network models. On the other hand, when detailed node-breaker (NB) models are used, no network reduction is necessary. This allows joint estimation of system states and network topology. For testing SE applications using NB models, an expanded version of the IEEE 300-bus system is created. The following changes are made to the original BB model to generate the NB model:The original system information (branch impedance values, loads and generators) in the IEEE 300-bus system is retained.All transmission buses are treated as substations with either double-bus-double-breaker, ring-bus, or breaker-and-a-half configurations, based on the number of incident lines.To terminate both ends of each regular branch between two circuit breakers, 1186 zero-impedance branches are added in the new NB model. The flows through these branches constitute the new SD-flow states.With the addition of SDs, the node count goes up from 300 in the BB model to 1233 in the NB model. All new nodes are given a unique four digit bus number.

背景概述

该数据集是基于IEEE 300-bus系统扩展的节点-断路器（NB）模型，专为测试状态估计应用而设计。它通过保留原始系统信息、将传输总线配置为变电站并添加1186条零阻抗分支，将节点数量从300个增加到1233个，以支持系统状态和网络拓扑的联合估计。
