【 摘 要 】

For the thermal inertia of houses and buildings, air conditioning (AC) cluster shows the potential in load frequency control. In this study, the authors propose a complete control framework for friendly accepting ACs to participate in secondary frequency regulation service without causing discomfort. An aggregator is hired to continually estimate the regulation capacity of ACs cluster by a heuristic simulated search algorithm, which could be guaranteed in a given duration. The external characteristics of the AC aggregations are set like a virtual power plant, which takes a droop curve for primary frequency control and a translation character for secondary frequency control. Simulation shows the capability for AC aggregations in load frequency control.
