Abstract
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.
Claims16
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;
- and
- finding 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.

An apparatus comprising:
- at least one processor;
- and
- a non-transitory computer readable storage medium having computer readable program code embodied therewith and executable by the at least one processor, the computer readable program code comprising:
- computer readable program code configured to interface with meters in an electric power grid, subsequent to repairs, maintenance or rebalancing efforts relative to the electric power grid;
- computer readable program code configured to obtain power-related measurements from the meters;
- computer readable program code configured to receive the power-related measurements at at least one remote device;
- computer readable program code configured to consolidate and process the power-related measurements to determine an updated network connectivity model subsequent to the repairs, maintenance or rebalancing efforts;
- wherein the determining comprises:
- analyzing a time series of measurements, over time steps, from at least some of the meters;
- and
- finding 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
- computer readable program code configured to store the updated network connectivity model at a data storage location.

A method comprising:
- utilizing at least one processor to execute computer code configured to perform the steps of:
- interfacing with smart meters in a power network, and with at least one meter upstream from at least one smart meter in the power network, subsequent to repairs, maintenance or rebalancing efforts relative to the power network;
- receiving measurements from the smart meters;
- receiving measurements from the at least one meter upstream from at least one smart meter;
- consolidating measurement data from the smart meters and the at least one upstream meter;
- said consolidating comprising:
- analyzing a time series of measurements, over time steps, from at least some of the meters from:
- the smart meters and the at least one upstream meter;
- and
- finding a sparsest set of the meters whose measurements approximately add up to the measurements of a given meter to determine connectivity among the meters;
- mapping connections between the smart meters and the at least one upstream meter based on the consolidated measurement data, to determine an updated network connectivity model subsequent to the repairs, maintenance or rebalancing efforts;
- and
- storing the updated network connectivity model at a data storage location.
