Abstract: In order to realize the orderly participation in demand response (DR) for the large scale residential flexible loads, the load aggregators can be used to aggregate the flexible loads. In order to reduce the impacts of DR scheduling on the residential users, firstly, the flexible loads are clustered according to different energy demands of the users. Secondly, the electricity consumption satisfaction function is constructed to prioritize all kinds of loads, and the loads with higher priority levels will be scheduled by setting different compensatory prices. Finally, a scheduling decision model is constructed to maximize the profits of load aggregator. Simulation result shows that the proposed approach can effectively reduce the difference between the peak and valley load demands, meanwhile, it will reduce the influence of DR scheduling on electricity consumption satisfaction of the users.
