Abstract

本发明公开了一种考虑电力通信不确定性的量子密钥分发网络随机规划方法，1、搭建基于可信中继的光纤QKD保密通信网架构；2、建立电力系统QKD网络的两阶段随机QKD规划模型，首先建立目标函数为最小化多个场景下系统信息风险指数，然后建立光纤QKD约束、部署投资约束、带宽和延时约束、量子信息流约束条件；3、生成步骤2所建模型的典型场景，建立电力侧的不确定性模型，并将其映射到信息流的波动中，生成几种典型的QKD网络随机规划场景；4、利用商业求解器求解步骤2所建模型，获取多场景下最优的量子资源优化部署与调度方案。本发明方法提高了电力通信系统的安全性，提高QKD网络应对通信不确定性的能力，提升了量子资源的利用率。
