Demand response（DR）is an important part of demand side management（DSM）. Choosing the suitable users to participate in demand response is a key issue in the implementation of demand response. Firstly

the user satisfaction model is developed

in which the satisfaction of the user’s electricity consumption and the satisfaction of the electricity expenditure are both taken into account. Then

based on the characteristics of different load on the user side

a capacity model that users can participate in adjustment under different response levels is constructed. Thus

an integer programming model for automatic screening of users in demand response is proposed

which can be solved by using the branch and bound method. Finally

by using the case study

the usefulness and feasibility of the model is illustrated

which shows that the strategy is fair and effective.
