  • Patent number: 11359933
    Abstract: A method for managing communications within a network comprising utility meters, each associated and connected to at least one utility management center through at least one intermediate data concentrator. A message is sent by a utility meter to the destination data concentrator. This message includes metering data measurement reported by said utility meter, its utility meter identifier, the destination data concentrator identifier and the management center identifier. Then, on the basis of several metering data measurements, a metering counter differential consumption value is calculated by difference of two metering counter consumption indexes measured by the utility meter within a time period interval. Then, a report containing at least the metering counter differential consumption value is sent from the destination data concentrator towards the utility management center to which said utility meter is associated.

  • Patent number: 11334033
    Abstract: Techniques for operational planning in a microgrid by means of optimization are provided. This involves a power exchange with a primary grid being taken into consideration. The operational planning in this case is performed by using an optimization, e.g. a (mixed) integer linear optimization. The various examples describe how a power exchange (balancing) can be provided for a primary grid to which the microgrid is connected. In particular, this is achieved by taking into consideration a distinction for the constraint of the optimization. In this manner, a lead time between a request for the power exchange and the actual activating of the power exchange can be taken into consideration.

  • Patent number: 10998727
    Abstract: Disclosed techniques include power management across point of source to point of load. Energy is obtained from points of energy generation, where data obtained at a time of energy generation includes information on energy and metadata about the energy. Connection is enabled from the points of energy generation to a large-scale energy storage subsystem. Load information is received from points of load, where the points of load are connected to an energy grid. Processors are used to calculate an energy control policy, based on information on the energy, the energy metadata, availability of the large-scale energy storage subsystem, and the load information. Routing of the energy is controlled from the points of energy generation to the points of load based on the energy control policy. The large-scale energy storage subsystem is controlled based on the energy control policy.
