In high renewable penetrated power systems, system frequency regulation and stability is a major challenge. In the demand-side, the thermostatically controlled loads (TCLs) in smart buildings can be exploited for the power system ancillary services including frequency regulation. In this paper, smart buildings with TCLs are proposed for power system frequency regulation services. The smart buildings are aggregated together by leader-follower consensus algorithms with sparse communication infrastructure. Then the distributed aggregation of smart buildings will provide aggregated power response in the load frequency control. The leader’s control signal is generated by both frequency measurement and automatic generation control signal. This method can provide fast, dynamic, and distributed power regulation with fair power and comfort sharing among all participate smart buildings. We have conducted both system contingency and normal operation scenarios to validate the proposed approach.
