An electricity network can have an amount of electricity available for provisioning to a plurality of service sites served by a network manager. A service site may be determined from among the plurality of service sites. The service site may include local assets. The network may also include network manager-operated assets. An objective function may be used to determine a dynamic operating envelope for the service site, which indicates an amount of power that the service site may be permitted to put onto or take off the electricity network. In some instances, the network manager may use an objective function which uses a dynamic operating envelope when controlling manager-operated assets. The service site may receive an instance of such a dynamic operating envelope and control a local asset in response to the dynamic operating envelope. In some instances, the service site may use an objective function which uses a dynamic operating envelope when controlling local assets.

Various embodiments disclose a method comprising generating, by a central server, a list of locations where a stolen meter is likely to be used, identifying, by the central server, a first meter having one or more characteristics of a stolen meter, and in response to determining that a first location associated with the first meter meets one or more distance criteria relative to a second location on the list of locations, performing, by the central server, a remedial action in relation to the first meter.

An electricity meter and electricity system or grid that is hardened against attack vectors is described, and provided in part by automated multiple-factor authentication over multiple communication networks. In an example, a utility company may control an advanced metering infrastructure (AMI) network to provide internal communications. Metering devices may utilize customer's Wi-Fi to gain access to the internet, allowing electricity consumption data to be transmitted over the internet. Multiple authentication factors are used to prevent a bad actor from impersonating the metering device or cloud server. In an example, each metering device determines a secret, and sends the secret over the AMI network to a utility company server, and which relays the secret to the cloud server. The cloud server uses the secret to establish trust with metering devices. Additionally, the metering devices and the cloud server have signed certificates, which are used in additional authentication processes.

Techniques for sharing resources between a radio access technology (RAT) modem (e.g., an LTE modem) and a processor-based radio (e.g., a software-defined radio) are described. In an example, operation of the RAT modem establishes an extended discontinuous reception mode (eDRX) cycle with a cellular system. The RAT modem sends eDRX scheduling information, that is based at least in part on the eDRX cycle, to the processor-based radio. Operation of the processor-based radio identifies paging opportunities (POs) of the eDRX cycle, based at least in part on the eDRX scheduling information. Operation of the processor-based radio manages usage of shared resources (e.g., transmit and receive amplifiers, digital signal processing elements, memory devices, elements of physical layer(s), and/or antenna(s), etc.). The managing may be based at least in part on the identified POs. The managing avoids conflicts between the RAT modem and the processor-based radio over the shared resources.

A method, apparatus, and system for determining validity of phase assignments by a phase identification model are disclosed. For example, the method includes predicting a phase correlated with each electricity meter of a plurality of electricity meters based on voltage time series data collected over a preselected collection time period, the phase being one of a first phase, a second phase, or a third phase; selecting a reliability parameter associated with predicted phases of the plurality of electricity meters; determining whether a parameter value associated with the reliability parameter meets a threshold parameter value; based on determining that the parameter value meets the threshold parameter value, determining that the predicted phases of the plurality of electricity meters are valid; and based on determining that the parameter value fails to meet the threshold parameter value, determining that the predicted phases of the plurality of electricity meters are invalid.

A multi-piece static fluid meter includes a register and a separate meter body. The register includes a first housing including a cavity which contains an ultrasonic transducer assembly and electronic component(s) of the static fluid meter. The meter body includes a second housing. When assembled, the first housing comprises a first portion of a flow passage and the second housing defines a second portion of the flow passage. The first and second housings can be formed of a thermoplastic and thermoplastically welded together. In some examples, one or more reflectors may be disposed in the flow passage and configured to reflect signals from the ultrasonic transducer assembly through a flow of water or other fluid to be measured. The register can include multiple mating surfaces configured to mate with different meter body configurations, allowing a single register design to be used with multiple meter body configurations.

An energy efficiency data collection system architecture may be configured to enable efficient and accurate collection of energy efficiency data associated with users and/or sites associated with users and generation of profiles associated with the users based on the energy efficiency data. An energy efficiency data collection service may receive location information, image data, and user-input data from an application operating on a mobile device associated with a user. The energy efficiency data collection service may generate profiles based on the information received from the application and may provide incentives to the users in response to participating in an energy efficiency data collection survey.

In the context of an electrical utility system, changing cloud conditions may cause a customer having solar panels to greatly increase or decrease electrical demand in a difficult-to-predict manner. Accordingly, a spinning reserve maintained by an electric utility company must be larger, and is therefore more expensive. In an example, the spinning reserve may be managed by: calculating a stable sequence of forecasts of smoothed real-time consumption, wherein the calculating is based at least in part on smoothed estimates of consumption data. A stable sequence of forecasts of real-time measured load may be calculated by subtracting forecasts of real-time distributed solar photovoltaic (PV) generation data from the stable sequence of forecasts of smoothed real-time consumption. The spinning reserve of the electricity system may be controlled based at least in part on the stable sequence of forecasts of real-time measured load.

Techniques for a network protocol for devices and nodes withing a wireless network include a method that includes receiving, by a first node included in a subtree of nodes within a wireless network, a first address list from a second node, the second node being a parent of the first node in the wireless network, wherein the first address list includes addresses of nodes along a path between the second node and a root node of the subtree of nodes; and in response to an address of the first node being included in the first address list, disconnecting, by the first node, from the second node.
