With the continuous research on integrated demand response (IDR), the analysis of residential customers' IDR characteristics and the exploration of IDR potential are drawing more and more attention. Therefore, load aggregators(LA) are considered to participate in the study of integrated demand response based on user comfort and consumption psychology. Firstly, we establish various types of response load models taking into account user comfort and consumption psychology, and then establish the IDR model of users. Secondly, the LA equipment optimization operation model is established based on the LA internal equipment modeling. Finally, the analysis shows that the proposed strategy can provide a more detailed and accurate comprehensive demand response strategy for residential customers and achieve a win-win situation for both LA and residential customers.
