摘要:

分布式能源发电的部署增加以及电动汽车和热泵等新型大型电力负载的集成,对低压配电系统的正确可靠运行提出了挑战。为了解决潜在的问题,在文献中提出了主动管理解决方案,这需要配电系统模型,包括在网络中的所有消费者的相位连接。然而,在实践中往往无法获得关于相位连通性的信息。在这项工作中,几个电压和功率测量为基础的相位识别方法,从文献中实现。一个一致的比较的方法是在不同的智能电表精度等级和智能电表的普及水平,使用公开的数据。此外,提出了一种新的方法,利用集成学习,可以结合不同的测量活动的数据。结果表明,与来自相同精度等级的智能电表的功率数据相比,电压数据通常可以获得更好的结果。如果功率数据也是可用的,新的集成方法可以提高从电压数据单独获得的相位识别的准确性。

英文摘要:

The increased deployment of distributed energy generation and the integration of new, large electric loads such as electric vehicles and heat pumps challenge the correct and reliable operation of low voltage distribution systems. To tackle potential problems, active management solutions are proposed in the literature, which require distribution system models that include the phase connectivity of all the consumers in the network. However, information on the phase connectivity is in practice often unavailable. In this work, several voltage and power measurement-based phase identification methods from the literature are implemented. A consistent comparison of the methods is made across different smart meter accuracy classes and smart meter penetration levels using publicly available data. Furthermore, a novel method is proposed that makes use of ensemble learning and that can combine data from different measurement campaigns. The results indicate that generally better results are obtained with voltage data compared to power data from smart meters of the same accuracy class. If power data is available too, the novel ensemble method can improve the accuracy of the phase identification obtained from voltage data alone.
