Modeling and optimal scheduling of residential controllable load with TOU price

On the basis of Home Energy Management System (HEMS), this paper studies a residential load scheduling problem in Time-of-Use pricing environment. First, we propose a classification of residential controllable appliance according to each characteristic and provide corresponding mathematical description. This classification could cover almost all the common appliances. Then, this paper establishes a residential load scheduling model under Time-of-Use pricing. Aiming at minimizing consumer cost as well as peak valley difference, this model considers the coordination of various kinds of appliances and distributed generation. In order to confirm the function of residential load scheduling model in controlling electric energy cost and decreasing peak valley difference, we analyze the result of load scheduling under diversified conditions in simulation.
