Optimal Operation Strategy of Data Center Aggregators for Demand Response Considering Temporal and Spatial Load Shift
利用聚合技术构建数据中心聚合商以参与系统需求响应,提出一种计及负荷时空转移需求响应的数据中心聚合商最优运行策略.首先,根据数据中心的物理特性,建立负荷时空转移需求响应模型;然后,以数据中心运行成本最小化和数据中心聚合商利益最大化为目标,建立计及负荷时空转移需求响应的数据中心聚合商最优运行模型;最后,通过Karush-Kuhn-Tucker(KKT)条件以及大M法将双层模型转换成单层混合整数线性规划模型进行求解.仿真结果表明:所提最优运行策略可有效提高数据中心内工作负荷的灵活性,并促进数据中心运行经济性的提高.
This paper uses aggregation technology to construct data center aggregators to participate in system demand response,and then proposes an optimal operation strategy of data center aggregators considering the demand response of load temporal and spatial shifts.First,according to the physical characteristics of the data center,the load time-space transfer demand response model is established.Then,the optimal operation model of data center aggregators was established with the goal of minimizing the operation cost of data center and maximizing the profit of data center aggregators.Finally,by using Karush-Kuhn-Tucker condition and large M method,the two-layer model is transformed into a single-layer mixed integer linear programming model.The simulation results show that the proposed optimal operation strategy can effectively improve the flexibility of the workload in the data center and promote the improvement of the operation economy of the data center.
