Distributed Demand Response of the Integrated Energy System in an Industrial Park

Integrated demand response (IDR) is typically implemented by centralized dispatching, which is insufficient in protecting users' information privacy and control autonomy. This paper proposes a distributed IDR method for industrial parks. Firstly, a distributed framework of interaction among industrial users, park energy management system and superior power grid is designed. Then, referring to the existing electricity market mechanism, an IDR market mechanism within the park is proposed. On this basis, the user's energy utilization optimizing model and the distributed IDR model are established, and the distributed model is proved to be convergent. The simulation result shows that the proposed IDR mechanism can reduce the response cost of users and the whole park.
