摘要
为促进数据中心多能互补以及低碳化,基于随机规划,提出了考虑电转气和碳捕集的数据中心微电网“源-荷”低碳优化调度模型。模型综合考虑了发电约束、数据负荷约束、电转气系统及碳捕集等约束,在发电侧引入碳捕集电厂-电转气-燃气机组(CCPP-P2G-CHP),将捕集的CO_(2)作为电转气系统合成甲烷的燃料;在负荷侧考虑即时型和可延迟型两种数据负荷,构建了数据中心功耗和数据负荷分配模型。仿真结果表明,所提模型在考虑碳排放的基础上,通过发电和数据中心数据负荷的优化调度,实现了数据中心微电网运行成本的最小化。
In order to promote multi energy complementary and low-carbon of data centers,a“source-load”low-carbon optimal scheduling model for data center microgrids is proposesd,which considers power to gas and carbon capture based on stochastic programming.The model considers the constraints of power generation,workloads,electricity to gas system and carbon capture.Carbon capture power plant,electric gas to gas,and combined heat power unit(CCPP-P2G-CHP)are introduced into the power generation side,the captured CO_(2) is used as the fuel for the synthesis of methane in the electric gas to electric system.Considering the interactive and batch workloads on the load side,a data center power consumption and workload allocation model are constructed.The simulation results show that the proposed model can minimize the operation cost of the data center microgrid through the optimal scheduling of power generation and workload based on the consideration of carbon emission.
