  • Patent number: 10724875
    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: 10559975
    Abstract: Distributed static synchronous series compensators (DSSSCs) which may also be designated tower routers capable of injecting series inductive or capacitive impedances to enable distributed power-flow control. When a large number of these (a fleet of) DSSSCs are distributed over the grid for power-flow control, it is necessary to ensure that coordinated communication and control capabilities are also established, enabling fast reaction to changes that can exist across the grid. A system architecture and method for enabling localized high-speed low-latency intelligent control with communications between subsections (local network) of the grid along with communication to the central Grid operations center at the utility for supervisory control is disclosed herein.

  • Patent number: 10557882
    Abstract: The present invention relates to an apparatus and a method for sensing an event occurring from a target device in a smart plug installed on a supply route of power applied to the target device. To this end, a power measurement unit which comprises the smart plug measures power supplied to the target device, and an event determination unit predicts an event occurring from the target device on the basis of a power signal characteristic of the supplied power measured by the power measurement unit. The power signal characteristic indicates a variation characteristic of the supplied power caused by the occurrence of the event on the basis of supplied power before the event occurs from the target device.

  • Patent number: 10527307
    Abstract: This invention relates to methods and systems for controlling appliances, particularly climate control appliances such as air conditioning units used in buildings. Embodiments of the invention provide methods and systems which provide a framework of semi-autonomous sensors and actuators which can achieve climate control without the need for centralised or explicit coordination. In certain embodiments, the climate control system is capable of identifying suitable pairings of sensors and actuators and taking into account actions of other actuators. The embodiments have particular application in buildings where large numbers of individual sensors and actuators are deployed in an ad-hoc or unplanned manner over time, but can communicate with each other. The embodiments of the invention can provide improved efficiency, reduced infrastructure costs, improved flexibility and can be deployed across multiple sites.

  • Patent number: 10528654
    Abstract: Examples related to facilitating analysis of an electrical power system are disclosed. One disclosed example provides a device comprising a display, a processor, and a storage device storing instructions executable by the processor to receive a request to operate in first and second input/output modes. In the first mode, the instructions are executable to display a graphical representation of an electrical power system illustrating components and connectivities in a schematic view, and receive a user input specifying a selected component of a plurality of candidate components and also an associated connectivity. The instructions are executable to display the selected component in the graphical representation of the electrical power system and store the selected component and associated connectivity in a data structure. In the second mode, the instructions are executable to display a text-based representation of the distribution system organizing the components and connectivities in a tabular view.

  • Patent number: 10520332
    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.
