Aiming at the strong dispersion and multiple influencing factors,this paper proposes a load aggregator(LA)optimization and scheduling method that considers the response potential of residential users.Firstly,based on the prospect theory in behavioral economics,a demand response potential model considering user psychology is modeled.Secondly,the maximum value of residential demand response potential considering user psychology under the probability distribution of different incentive prices is calculated.Finally,aiming at maximizing the income,an LA optimal scheduling method is proposed,which includes adjustable load of residential household,electric vehicles charging station,photovoltaic system,and energy storage system.Simulation results show that the proposed method can effectively improve the enthusiasm of residential users to participate in demand response while stimulating the potential response of users and increase the amount of user response.
