| Abstract |
Novel Smart Grid functions demand for reliable grid topology information. Currently, on distribution grid level, such information is only statically (i.e. configured once - e.g., in CIM or alike format) or not at all available. The static topology data may become invalid due to a switching action or grid extension. In this paper we present a Smart Grid application, which validates such a given CIM-represented grid topology on the basis of power profiles measured by grid monitoring devices. The topology is extracted as graph representation, field measurements are represented by an abstract grid model, and correlation of load profiles is calculated by a presented comparison algorithm. We demonstrate the application of the topology validation in the ASCR Smart City testbed and show its extension to a topology identification application. The two applications' field usage proves useful functions on which further Smart Grid applications will build upon. |
