Residential electricity load scheduling for multi-class appliances with Time-of-Use pricing

In this paper, we study an electricity load scheduling problem in a residence. Compared with previous works in which only limited classes of appliances are considered, to consider various appliances with different operation and energy consumption characteristics with each other, we classify appliances into four classes and provide mathematical models to describe them. With the developed appliance models, we also propose an electricity load scheduling algorithm that controls the operation time and energy consumption of each appliance adapting to Time of Use (TOU) pricing and its operation and energy consumption characteristics to minimize the total electricity bill.
