The inverter air-conditioning load is modeled based on the study of its load characteristics.Combining both the advantages of temperature control and frequency control,a frequency control method with fixed operation time constraint is proposed considering the demand response incentive scheme and satisfying the users'comfort requirements.Based on the peak load reduction optimal model of air-conditioning group,a control algorithm of peak load reduction by the inverter air- conditioning group is designed.With different purposes of control,this algorithm obtains the maximum load reduction potential or the optimal economy,respectively.The correctness and superiority of the method are verified through case study, and the reduction effects of different objectives and factors are compared and analyzed.
