摘要： An improved AC power supply is described. The supply identifies the load through monitoring the current and voltage wave forms and phase relations with the AC Mains. The comparison is done in conditions where the power to the load is programmably varied through use of a control switch located in the line and neutral between the AC mains and the load. The program of controlling the switch is varied to optimize the ability to distinguish similar load types. The switch can be further used to control power to the load that varies according to a set of rules based upon the identity of the load. In a preferred embodiment, the design enables high efficiency with minimal components that may be fully integrated onto silicon.

摘要： A system and method for detecting and resolving conflicts in transmissions from DTs located on the edge of an electrical power distribution grid. By examining the frame and time slot of the conflict and inferring a possible DT involved in the transmission conflict and reassigning the DT's transmission to another frame and time slot, the conflict should be resolved and the data being provided by the DT is not necessarily lost nor is its receipt unreasonably delayed.

摘要： This document relates to electricity management using modulated waveforms. One example modulates electricity to obtain modulated electricity having at least two different alternating current frequencies including a first alternating current frequency and a second alternating current frequency. The example delivers the modulated electrical power having the at least two different alternating current frequencies to multiple different electrical devices, including a first electrical device configured to utilize the first alternating current frequency and a second electrical device configured to utilize the second alternating current frequency. The modulated electricity can be delivered at least partly over an electrical line shared by the first electrical device and the second electrical device.

摘要： Dispatch engines service endpoints by transmitting dispatch signals to the serviced endpoints that cause the endpoints to adjust their electric power consumption from the electric power grid in accord with a control signal received by the dispatch engine. A market interface dispatch engine receives its control signal from an electric power grid managing entity, and downstream dispatch engines form a hierarchy cascading downstream from the market interface dispatch engine with each downstream dispatch engine being an endpoint serviced by a dispatch engine located upstream in the hierarchy. The control signal received by each downstream dispatch engine comprises dispatch signals transmitted by the upstream dispatch engine. The endpoints further include electric power-consuming loads. A suitable load controller comprises separate power interface and logic elements operatively connected to define the load controller, with the logic element powered by low voltage DC power received from the power interface element.

摘要： A demand side electric power supply management system is disclosed. The system comprises an islanded power system having a point of coupling to a supply grid. The islanded power system supplies a plurality of electric loads, each of which is associated with a load controller to control the maximum power demanded by that load. A measuring means associated with the point of coupling measures the total power transfer between the grid and the islanded system, and a system controller monitors the measured power transfer relative to a set point and provides a control signal to a plurality of load controllers. Each load controller receives substantially the same control signal and determines the maximum power which the or each load associated with the load controller is allowed to draw from the islanded power system based on information contained in the control signal.
