Distributed Automated Demand Response
Loads on an electric power system are configured with under-frequency relays in which the frequency setpoints and delay times for reclosure are uniformly distributed. If demand exceeds supply in the system, frequency will decrease. The decrease in frequency will actuate relays and reduce load to the point where demand will meet the available supply. After its engineered delay time, each relay will attempt to close contact and reestablish the load.
