  • Publication number: 20110221276
    Abstract: An energy storage medium is combined with a secondary energy source that supplies power to an electricity distribution grid. The charge and discharge behavior of the energy storage medium is controlled so that rapid increases in the output of a secondary source of energy are absorbed by the storage system, whereas rapid decreases in the output of the secondary source are compensated by discharging stored energy onto the grid. The combined contributions of the secondary source and the energy storage system ensures a rate of change that does not exceed a defined level. Maximum and minimum output power levels for the secondary source can be established to define a normal operating range. The charging or discharging of the energy storage system is also performed when the secondary output power level exceeds or falls below the limits of the defined range.

  • Patent number: 7839027
    Abstract: Systems, apparatus, and methods are provided for maintaining the state of charge of energy storage devices such as batteries, flywheel, capacitors, or other technologies that are energetically coupled with the electricity grid to support ancillary services. To reliably respond to requests to regulate the grid, the charge on the energy storage device is sustained or restored to a specified range in a manner that optimizes the readiness of the energy storage device to supply ancillary services in light of the condition of the grid. A state of charge (SOC) of the energy storage device and the grid frequency may be monitored. When a request from the operator to regulate the grid frequency is not being serviced, the charge of the energy storage device may be increased or decreased so that the charge may be sustained within the specific range. Once the SOC falls outside of the first range, charge may be added to or removed from the energy storage device when the grid frequency has appropriate values, e.g.

A destination transceiver such as, a central transceiver, has a unique, permanent identification with a predetermined numerical link layer level n. A plurality of remote transceivers each having a unique, permanent identification and a variable, stored numerical link layer x where x>n and x and n are integers and x-n-1 represents the number of remote transceivers through which a communication must pass to reach the destination transceiver. The variable, stored numerical link layer level of each remote transceiver is dependent upon the dynamic condition of the network at the time of message transmission from or through the particular remote transceiver.
