A Novel Smart Grid Device Location Mapping Technique

摘要

We propose a technique to accurately and quickly determine and resolve the geo-spatial and logical location of grid-resident devices. The technique compare downstream current profiles (DCP) with the superposition of current profiles at the substation (UCP) in the grid. Since small amounts of noise current and perturbations will show up at the substation due to active devices on the grid, the electrical location of each meter can be determined by comparing passive line data from the meter location (DCP) against all the substation feeder lines (UCP). The significance of this approach is that it is passive and efficient as it does not require additional hardware or communication signals to be introduced to grid infrastructure. The technique can be integrated into current grid systems and implemented using existing smart meter data acquisition facilities and computer/software processing at the utility's datacenter.
