摘　　要：高耗能的大型数据中心对其所在区域智能电网的负载均衡有较大影响。针对这种情况,提出电网感知的云计算服务请求路由优化算法。通过对云计算系统的服务请求路由调整,结合电网功率流分析,将服务请求路由到电网余量充沛的数据中心来改善电网支路的传输负载。在IEEE 24节点可靠性测试系统上的仿真结果显示:算法能根据数据中心节点的电网负载情况,调整服务请求路由,显著改善电网的负载均衡问题和提高电网的鲁棒性。Large data centres with high energy consumption have major impact on the load balancing of smart grid in regions they are located. In view of this, we proposed a grid aware service request routing optimisation algorithm in cloud computing. Through adjusting the service request routing in cloud computing system and combining with the grid power flow analysis, the service requests will be routed to the data centre with plenty power margin so as to improve the transmission load in power grid branches. Simulation results on IEEE 24 bus reliable test system showed that this algorithm can adjust the service request routing according to the grid load situation at the node of data centre, and significantly meliorated the power grid load balancing issue and improved the robustness of power grid.
