Abstract:
A method for performing energy management for a building includes generating a stack of energy loads representative of a plurality of building energy loads. The energy loads are prioritized from highest priority energy loads to lowest priority energy loads. The prioritized energy loads are then compared to a building power threshold. The lowest priority energy loads are shed until a sum of remaining energy loads is equal to or less than the building power threshold. The remaining energy loads are serviced. The processes of prioritizing the energy loads, comparing the prioritized energy loads to a building power threshold, and shedding the lowest priority energy loads is repeated in response to changes in circumstances affecting the building.
Abstract:
Systems and methods for the estimation of jurisdictional boundary crossings for fuel tax reporting relating to a commercial motor vehicle (CMV). One method includes defining a geo-fenced region for a jurisdiction. The location of the vehicle is determined using a positioning system and the geo-fenced region. When positioning system information is unavailable for a period of time, the location of the vehicle is estimated, including determining if a distance between two consecutive positioning system points is greater than a threshold value, and using predetermined route information to estimate where the vehicle has crossed the geo-fenced region boundary.
Abstract:
Methods and systems to minimize energy cost in response to time-varying energy prices are presented for a variety of different pricing scenarios. A cascaded model predictive control system is disclosed comprising an inner controller and an outer controller. The inner controller controls power use using a derivative of a temperature setpoint and the outer controller controls temperature via a power setpoint or power deferral. An optimization procedure is used to minimize a cost function within a time horizon subject to temperature constraints, equality constraints, and demand charge constraints. Equality constraints are formulated using system model information and system state information whereas demand charge constraints are formulated using system state information and pricing information. A masking procedure is used to invalidate demand charge constraints for inactive pricing periods including peak, partial-peak, off-peak, critical-peak, and real-time.
Abstract:
Methods and apparatus for differential bandwidth metering in a network implementing direct peerings. A system includes a plurality of resource collections and a billing manager. The billing manager obtains a first metric of network traffic transmitted on behalf of a client to obtain one or more services from one or more resource collections. The billing manager also obtains a second metric of network traffic transmitted on behalf of the client over one or more private links, where each private link is set up to establish a network path between a respective client network of the client and a respective resource collection of the plurality of resource collections. The billing manager provides composite billing information to the client comprising a differential billing amount dependent upon a difference between the first metric and the second metric.

Abstract:
Disclosed are apparatus and related methodologies for transmitting data in a gas AMI network. Data may be transmitted bi-directionally between selected endpoint devices and data collection devices to central or head end equipment. Transmitted data may include parameter updating data for selected endpoint devices, and collected data from selected endpoint devices. Endpoint physical area conditions may be monitored for selected of the endpoint devices including monitoring for and reporting of physical changes in the area surrounding cathodic protection systems.
