Abstract

A server device includes a storage device to store policies that govern the manner in which a curtailment operation or a replenish operation are performed. The policies include a threshold associated with a quantity of power consumption permitted by smart grid devices or another threshold associated with a minimum quantity of power to be supplied by a smart grid device. The server device also includes a processor to obtain, via a web service enabled by a tunneling protocol, a quantity of power consumed by the smart grid devices and another quantity of power to be supplied by the smart grid device; compare the threshold with the quantity of power; send an instruction to perform the curtailment operation when the quantity of power exceeds the threshold; compare the other threshold with the other quantity of power, when the quantity of power is less than the threshold; and send another instruction to perform the replenish operation when the other quantity of power is less than the other threshold.
