分布式发电和低碳负荷已经导致配电网络的运行受到一些限制，而光伏发电、热泵和电动汽车等的更高渗透率将加剧这些问题。在这种新的形势下，为了有效地管理配电网，加强对配电网的实时监测和控制就显得十分必要。未来，配电网络运营商将拥有智能电表测量，以促进配电网络的安全和经济高效的运营。本文研究应用智能电表测量扩展配电网的可观测性。一个集成的负载和状态估计算法的开发和测试使用住宅智能计量测量和11千伏住宅配电网。仿真结果表明，智能电表测量，实时和伪测量来自他们，可以一起使用状态估计，以扩展配电网的可观测性。集成的负载和状态估计算法被示出在网络的每个母线处产生准确的电压幅值和角度。因此，该算法可用于加强配电网的监测和控制。
Distributed generation and low carbon loads are already leading to some restrictions in the operation of distribution networks and higher penetrations of e.g. PV generation, heat pumps and electric vehicles will exacerbate such problems. In order to manage the distribution network effectively in this new situation, increased real-time monitoring and control will become necessary. In the future, distribution network operators will have smart meter measurements available to them to facilitate safe and cost-effective operation of distribution networks. This paper investigates the application of smart meter measurements to extend the observability of distribution networks. An integrated load and state estimation algorithm was developed and tested using residential smart metering measurements and an 11 kV residential distribution network. Simulation results show that smart meter measurements, both real-time and pseudo measurements derived from them, can be used together with state estimation to extend the observability of a distribution network. The integrated load and state estimation algorithm was shown to produce accurate voltage magnitudes and angles at each busbar of the network. As a result, the algorithm can be used to enhance distribution network monitoring and control.
