Abstract:
Systems and methods for performing energy transactions including a number of market participant nodes associated with an energy market participant, and a number of market authority node devices associated with a market authority. A network operator node device is further included, which is associated with a network operator. The market participant node device, the market authority node devices, and the network operator node devices are configured to communicate with each other to facilitate an energy transaction.
Abstract:
An improvement to a utility (U) meter's (M) meter reading schema. The improvement includes a device (D) responsive to a native language with which a meter is programmed to convert communications to and from the meter from that native language into a neutral language. The neutral language is convertible by other meters programmed with different native languages into the native language of a particular meter for meters programmed with different native languages can communicate with each other. This allows facilities within a localized area of a utility's power grid (G) to form into a micro-grid (MG) in which meters programmed with the same or different native languages can communicate with each other without having communications between them routed through a central location of the utility.
Abstract:
A node in a power distribution system is described. The node includes an electrical connection to a single-phase power signal from an AC mains power source, a wireless communication interface configured to receive a first phase synchronization message, and a controller. The controller is configured to determine whether the first phase synchronization message is acceptable and detect a zero-crossing event on the single phase power signal subsequent to the receipt of the first phase synchronization message in response to determining that the first phase synchronization message is acceptable. The controller is further configured to calculate a time difference between the receipt of the first phase synchronization signal and the detected zero-crossing event, determine a local phase angle based on the time difference, and establish an identity of the single phase power signal based on the local phase angle.
Abstract:
Systems for determining a phase of a device coupled to an electrical distribution system. The system includes a number of gateway devices configured to transmit a synchronization signal. The gateway device receives a node response message from a first node device that includes a duration value indicating a time between a receipt of the transmitted synchronization signal and a detected zero crossing. The gateway device compares the duration value against duration values received from node devices with a known phase connection and determines a phase of the first node device based on the comparison.
Abstract:
Improvements to IEC 61968-9:2013 meter reading schemas. These include significantly compressing messages into a single integer number which, when transmitted over a utility's communication system, is used to configure meters at utility user locations, obtain meter data, command and control operations at a utility location, and expand messaging capabilities. A method is disclosed for simplifying the IEC 61968-9:2013 schema for communications between a HeadEnd utility communications facility and the meter at an EndPoint so to enable use of the schema for operations it could not previously perform. While providing this enhanced capability, the IEC 61968-9:2013 schema's ability to function for its intended purpose; i.e., meter reading and control, is not compromised or impeded.
Abstract:
An energy management system (EMS) is connected to a distribution grid upstream of substation transformers and provides a demand response (DR) program signal to the distribution grid. The program signal specifies a target load adjustment. A plurality of DR RCE (Demand Response Remote Communication Equipment) are connected to phases of the distribution grid downstream of a corresponding substation transformer. Each DR RCE controls an operation of a plurality of endpoint devices. A plurality of FANG devices, each connected to phases of the distribution grid downstream of a corresponding substation transformer, receives the DR program signal via the grid. Each FANG device selectively controls power to its endpoint devices in response to a received DR program signal. As a result, the FANG device reduces the total power applied to its endpoint devices in response to the DR program signal.
