With the increasing deployment of smart meters and other smart grid sensors in distribution systems, the amount of available measurements grows unprecedentedly abundant. This change makes it possible to do distribution system state estimation, which provides more coherent and accurate as-operated condition serving as a foundation for various smart grid applications. This paper presents the development work on a distribution system state estimation (DSE) utilizing smart meter and other sensor data, as well as traditional SCADA telemetries. It describes the problem formulation, solution methodology, modeling issues unique to distribution systems, and test results on multiple distribution circuits from a large distribution company.
