Abstract
Due to the distributed and decentralized characteristics of air conditioning load, the distributed control strategy has advantages for the air conditioning load to participate in the demand response. However, existing approaches focus on the dynamic control performance with very few considerations on the cost. To fill this gap, this paper proposes a multiagent consensus control method considering the whole-process response cost of air conditioning. Based on the thermodynamic characteristics of air conditioning load in the load reduction process and recovery process, the cost function curve of air conditioning load is established. Then, the multiagent consensus control strategy is adopted to send the power adjustment information to each air conditioner to realize the optimal control of the air conditioning load. The simulation results verify that the proposed method can take into account the whole-process response cost of air conditioning loads and result in smaller control cost than existing methods.

Summary
With the increasing penetration of renewable energy, it is increasingly difficult for the power system to keep the active power balance by using generation side resources. The distributed consensus control strategy for air-conditioning load is designed in [12, 13], the control cost is not considered for the thermodynamic characteristics of air-conditioning load. Aiming at the distributed control problem of air conditioning load, this paper proposes a multiagent consensus control method that considers the thermodynamic characteristics of the whole process of air-conditioning load which is proposed to minimize the cost function while achieving the control target, so as to reduce the impact on user’s comfort. (1) Establishing a whole-process cost function considering the thermodynamics of air conditioners (2) Applying the multiagent consensus control method to air conditioners in order to minimize the overall cost of the control e arrangement of this paper is as follows.
