1. A method for controlling a distributed power system including an aggregator communicatively coupled to a plurality of nodes, each of the plurality of nodes including an associated load, said method comprising:
receiving, at the aggregator, a commanded power profile from an independent service operator, the commanded power profile including a commanded power deviation for the distributed power system;
calculating, using the aggregator, a score for each of the plurality of nodes based on a current power of each node, the score indicating a distance between the current power for the node and a midpoint between upper and lower power limits for the node;
selecting, using the aggregator, a subset of the plurality of nodes based on the calculated scores; and
commanding, using the aggregator, each node in the subset to adjust its current power by a respective predetermined amount, the predetermined amounts determined based on the commanded power deviation.
