Determining a connectivity model in smart grids

摘要

Methods and arrangements for determining a network connectivity model. Meters are interfaced with, and periodic synchronous power-related measurements are collected from different meters. Measurement messages are sent to a predetermined location for being consolidated and processed, and a network connectivity model is thereupon determined.

主权项

1. A method comprising:
utilizing at least one processor to execute computer code configured to perform the steps of: interfacing with meters in an electric power grid, subsequent to repairs, maintenance or rebalancing efforts relative to the electric power grid; obtaining power-related measurements from the meters; said obtaining comprising receiving the power-related measurements at at least one remote device; consolidating and processing the power-related measurements to determine an updated network connectivity model subsequent to the repairs, maintenance or rebalancing efforts; wherein said determining comprises:
analyzing a time series of measurements, over time steps, from at least some of the meters; andfinding a sparsest set of the meters whose measurements approximately add up to the measurements of a given meter to determine connectivity among the meters; and storing the updated network connectivity model at a data storage location.
