Data centers (DCs) are large power consumers with demand response (DR) capabilities in both time and special dimensions. This paper proposes a scheduling model for renewable energy integrated systems with DCs to improve renewable energy utilization. To protect the data privacy of data center operators (DCOs), a two-level distributed algorithm is proposed in this work. Finally, the proposed model is verified on an improved IEEE 118-bus power system with renewable energy farms and DCs. Simulation results prove that DCs’ participation in DR has a positive effect on reducing renewable energy curtailment and the proposed algorithm has high solution accuracy on the premise of privacy data protection of DCOs.
