LOW-FREQUENCY PWM APPLIANCE RESPONSE TO DEMAND RESPONSE MANAGEMENT SIGNALS

摘要

The present subject matter relates to energy management. Home energy management (HEM) devices are directed from a central control system to modify energy usage among appliances/loads within individual homes to meet energy source demand limitations. The HEM devices may work in cooperation with a group of such devices as a unit to negotiate with the central control system and then individually to control energy usage for their separately controlled home appliances/loads to meet group negotiated aggregate energy usage modification, for example, usage reductions so as to minimized peak usage demands on the energy source.

主权项

1. An energy management system, comprising:
a central control system including a demand management system; and a plurality of home energy management systems in communication with said central control system, each of said plurality of home energy management systems configured for communications with at least one home appliance, wherein said demand management system is configured to transmit demand response signals to each of said plurality of home energy management systems including instructions to modify overall system usage demand, and wherein each of said plurality of home energy management systems is configured to instruct the at least one home appliance to modify its energy consumption.
