Controlling load provided to an appliance at a socket by communication with a power system

摘要

A system 26 to control the amount of power supplied to individual loads 22, 28 so as to be able to have a finer degree of control of load shedding includes a load control module 50 to control the amount of power transmitted to a particular load plugged into outlet 58, to receive a power control command from a power system, and to transmit a power control acknowledgement to the power system. The system also includes a load monitoring module 52 that determines the amount of power supplied to the load and transmits a value representing the determined amount to the power system. The monitoring and control device may be implemented in the form of a wall socket.
