On the basis of the research on the load characteristics,the model of the inverter air conditioner is established.In circumstances that could satisfy the requirement of the users'comfort,design a control method of the single inverter air conditioning,and design a direct and easy aggregation control algorithm.At the same time,depending on the different order of air conditioning control,two goals are respectively to make full use of the load reduction potential or economy optimal.A power grid planning model is established considering the cost of the demand response,and the effectiveness of the control method and the planning scheme are proved by the case study.
