Coordinated control of load for aggregated air-conditioners (ACs) has been included in the normal operation of power system due to its better characteristics of spatial thermal storage. However, many problems will be brought out such as aggregated power oscillation, unstable response potential and excessive rebound load, when the diversity of load groups is destroyed for the control strategy. To solve this problem, the influence of temperature control on the power and response potential of single and aggregated ACs is analyzed, the time-varying power characteristic model and polymerization method of aggregated ACs are established based on the temperature control. Then, the two-stage coordinated control model of aggregated ACs with time-varying complementary characteristics is proposed based on the framework of time-phase coordinated control to improve the aggregated quality of air-conditioning groups, with the corresponding response and recovery strategies. Finally, Simulations based on 15 000 ACs show the influence of external temperature, temperature strategy and other factors on the aggregated power, meanwhile, the coordinated control strategy of time-phase air-conditioning groups is applied in demand response events. The results verify the efficiency of the proposed method.
