摘要:
An active load management system (ALMS) controllably restarts electrical service to service points in a utility service area after a power outage. The ALMS includes client devices installed at the service points and a central controller. In one embodiment, the controller associates numbers with the service points and stores the associations. Each service point may be associated with a unique number or a group of service points may share a number. After receiving notification that power is available, the controller determines a number and communicates the number to one or more of the client devices. Where the number was determined randomly, the client devices associated with the number may restart electrical service upon receipt of the number. Where the number was determined sequentially, a client device may determine its own random number and compare it to the received number. If a match occurs, electrical service can be restarted.

A utility employs a method for estimating available operating reserve. Electric power consumption by at least one device serviced by the utility is determined during at least one period of time to produce power consumption data. The power consumption data is stored in a repository. A determination is made that a control event is to occur during which power is to be reduced to one or more devices. Prior to the control event and under an assumption that it is not to occur, power consumption behavior expected of the device(s) is estimated for a time period during which the control event is expected to occur based on the stored power consumption data. Additionally, prior to the control event, projected energy savings resulting from the control event are determined based on the devices' estimated power consumption behavior. An amount of available operating reserve is determined based on the projected energy savings.

A control system and method to create an Internet Protocol (IP) enabled automatic gain control loop for encasing a desired cost value in a utility derived consumer controlled pricing envelope. A customer uses a web browser to view billing estimates for the current month as well as related months. The customer can set limits on the actual billing amount for the upcoming month and make adjustments to this amount if it seems unrealistic in the coming month. Control event actions are carried out to limit power usage within preferences set by the customer.

A server manages consumption of power supplied by at least one electric utility to multiple power consuming devices. Power flow to the consuming devices is enabled and disabled by controllable devices controlled by one or more client devices. The server includes a command processor, event manager, database, and client device manager. The command processor receives commands from the utility and issues event messages responsive thereto. The event manager maintains a power management status for each client device and issues event instructions responsive to event messages. The database stores information relating to power consumed by the consuming devices. The client device manager selects from the database, responsive to receipt of a power reduction event instruction, at least one client device to which to issue a message indicating a power reduction amount and/or identification of at least one controllable device to be instructed to disable power flow to associated consuming devices.

Methods for prioritizing load management messages on IP-based networks utilizing an Active Load Directory and IP capable two-way gateway. The messages being received from, or sent to, the ISP through the gateway contain a blend of regulated and unregulated data. The regulated data is high-priority utility load management data such as, equipment status and load control instructions. The unregulated data consists of Internet messages such as email and web site data. These methods process all regulatory data before unregulated data within strict time limits, providing the greatest possible load management control and energy savings. The methods emulate dedicated network processor memory in a manner that permits the rules for prioritizing, scheduling, and routing to remain the same across both hardware and software implementations.

摘要:
A system, which includes a system controller and client devices, manages consumption of power supplied by at least one electric utility to multiple power consuming devices. Electric power flow to the consuming devices is controlled by controllable devices, which are controlled by the client devices. The controller includes an event manager, a database, and a client device manager. The event manager generates event instructions, including instructions requiring a reduction of consumed electric power. The database stores, on a per client device basis and/or a per electric utility basis, information relating to power consumed by the consuming devices. The client device manager selects, based on the database information and responsive to a power reduction event instruction, at least one client device to which to communicate a message indicating a power reduction amount and/or identification of at least one controllable device to be instructed to disable power flow to associated consuming devices.
摘要:
A system and method for creating and making use of customer profiles, including energy consumption patterns. Devices within a service point, using the active load director, may be subject to control events, often based on customer preferences. These control events cause the service point to use less power. Data associated with these control events, as well as related environment data, are used to create an energy consumption profile for each service point. This can be used by the utility to determine which service points are the best targets for energy consumption. In addition, an intelligent load rotation algorithm determines how to prevent the same service points from being picked first each time the utility wants to conserve power.
摘要:
According to one embodiment, a client device manages consumption of power supplied by an electric utility to one or more power consuming devices. Power flow to the power consuming devices is controlled by one or more controllable devices, which are controlled by the client device. The client device receives a power control message (e.g., from a system controller), which may have been issued in furtherance of a power reduction event initiated by the electric utility. The power control message indicates an amount of electric power to be reduced and/or identification of at least one controllable device to be instructed to disable a flow of electric power to one or more associated power consuming devices. Responsive to the power control message, a flow of electric power is reduced (e.g., disabled) to at least one power consuming device based on the contents of the power control message.
