  • Patent number: 9496714
    Abstract: A method of balancing a demand for electricity is disclosed. Consumers of the electricity are organized into a hierarchical set of nodes. A demand for a node at a first level of the hierarchy is defined. A rate structure is defined at nodes of a second level of the hierarchy so that a sum of the electricity demands at the second level obtained in response to the defined rate structure is substantially the same as the defined demand at the first level.

  • Patent number: 9307620
    Abstract: A two-conductor hard-wired communications link accepts a value of at least one parameter from an environmental sensor in the form of data encoded on the conductors via current modulation. The sensor can be mounted in a location remote from a controller. A circuit connected to the sensor transmits an RF signal representing the value of the parameter detected by the sensor. A data relay connects to the hard-wired communication link of the controller. The data relay includes a receiver that receives the RF signal, and circuitry configured to extract the value of the parameter and to emulate a set of physical and protocol properties of the hard-wired communication link of the controller.

  • Patent number: 9283863
    Abstract: In a charging management system for electrical vehicles, a maximum charging current for a plurality of charging operations, e.g., for a plurality of charging stations and/or a plurality of electrical vehicles, is coordinated in a centralized or a decentralized manner while complying with predefined flexibly adjustable secondary conditions. The secondary conditions can include economic and/or technical stipulations. In addition to a centralized load management system, a decentralized load management facility carries out a load distribution via a master charging station or autonomously by each charging station itself. If the master charging station fails, a changeover is made to a backup master charging station. The method can be used, for example, in electrical mobility, in particular the electrification of individual traffic.

  • Patent number: 9264125
    Abstract: A decentralized communication device is provided that facilitates optimal positioning and orientation of one or more antennas for wireless communication with external devices. The decentralized communication device includes one or more master components and one or more slave components. The master and the slave components are physically separate and communicate wirelessly. In some embodiments the slave acts as a carrier frequency translator between the master and an external wireless device, where it communicates with the external device using a first frequency and communicates with the master using a second frequency which is different from the first frequency. In another embodiment the slave has most or all the physical layer to do the digital coding, digital modulation, data framing, data formatting and data packetization for communicating with an external device, in which case digital coding and digital modulation is distributed between the master and the slave.

  • Patent number: 9118207
    Abstract: Systems and methods are disclosed that can be used to broadcast or otherwise send load shed and other requirements over a network to recipients. One exemplary embodiment involves sending a first broadcast message to a first group of recipients. The first broadcast message requests compliance with a requirement but does not require a synchronous reply from the first group of recipients. The first group of recipients are each configured to automatically comply with the requirement in response to receiving the first broadcast message. The exemplary embodiment further involves determining, for example, based on actual load determination, to send a second broadcast message to a second group of recipients different from the first group of recipients and sending the second broadcast message to the second group of recipients, the second broadcast message requesting compliance with the requirement.

  • Patent number: 9118219
    Abstract: Determining the number of loads associated with each phase in a three-phase electric power system. The loads can be associated with the consumption of electric power at a node, such as a metering device located at a facility. In one implementation, a central device that is connected to such nodes via a smart grid and a radio frequency mesh network can be leveraged to determine a phase in real time. For example, the central device can include a processor that executes one or more computer program modules which can cause a load tap changer having access to a distribution feeder in the smart grid to vary a voltage level supplied across each phase of the power system. Additionally, the central device can communicate with nodes in the mesh network to cause the nodes to perform voltage measurements and collect information related to such measurements.

  • Patent number: 9110647
    Abstract: A method for managing an energy consuming load in a group of energy consuming loads and a method for managing the group of energy consuming loads. The method includes generating sets of load state data from the loads, making enablement state decisions for one or more loads using the sets of load state data, and implementing the enablement state decisions. Each of the enablement state decisions reflects an enablement state of a load, wherein the enablement state is either a load enabled state where the load is capable of operating even when the load is not actually operating or a load disabled state where the load is not capable of operating. A computer readable medium may include computer readable instructions for directing a processor to perform the methods and make the enablement state decision. Further, an apparatus comprised of a processor may be programmed to perform the methods.
