配电网低压状态估计由于缺乏实时量测，必须严重依赖于伪量测，而伪量测主要来源于标准负荷剖面。最近怀疑实际负荷曲线明显偏离SLP，目前正在进行研究工作，以量化和描述这种偏离，并合成更真实的曲线。由于配电系统SE正在试验部署，并且正在考虑使用任何可用的数据源，因此必须研究SE中负载分布的误差传播和不确定性分析。研究结果提供了提示的准确性，预期和校正将适用于经典的伪测量。
Low-voltage state estimation (SE) in distribution power system, because of lack of real-time measurements, must heavily rely on pseudo-measurements, primarily originating from standard load profiles (SLPs). Actual load profiles have been recently suspected of significantly deviating from the SLPs, and research work is ongoing to quantify and characterize this deviation and to synthesize more realistic profiles. The analysis of the propagation of error and uncertainty of load profiles in SE must be investigated, as distribution system SE in distribution is being experimentally deployed, and the use of any available source of data is under consideration. The findings provide hints on the accuracy to be expected and on corrections to be applied to classical pseudo-measurements.
