摘　　要：能源互联网和电网智能化的发展,需要更加先进的通信网络技术以满足电网监控数据的实时性、可靠性传输等需求,从而保障电网的可靠运行。将地面通信网络与卫星网络紧密结合,将有助于解决智能电网中面临的传输拥塞和空间覆盖问题。针对电网监控数据传输的带宽和时延要求,面向卫星通信网络与地面通信网络的无缝集成,文章提出了一种天地一体化的混合路由算法。该算法将路由切换建模为地面-卫星路由设备优化选择问题,通过地面网络以及地面与卫星连接部分之间的流量需求调整其传输路径,从而得到最优路径。仿真结果表明,所提出的混合路由算法在网络拥塞情况下,能够有效保证数据传输的吞吐量,并减小端到端时延。With the Intelligent development of energy Internet and power grids,to guarantee the reliable operation of power grid,more advanced communication technologies are needed to meet the real-time and reliable transmission requirements of power grid monitoring data.By combining the terrestrial network with satellite networks,the problem of congestion and coverage in smart grid will be solved.Therefore,aiming at the bandwidth and delay requirements of smart grid communication services,we propose a terrestrial-satellite hybrid routing algorithm.The proposed algorithm can provide seamless integration of satellite segment with terrestrial networks,in which the transmission path can be adapted according to traffic demands of terrestrial users,so as to obtain the optimal routing.Simulation results show that the proposed hybrid routing algorithm can also guarantee data throughput and reduce end-to-end delay under network congestion.
