摘　　要：为降低电力通信网多优先级业务传输的失效概率,提高系统可靠性,提出一种基于业务优先级和共享风险链路组(shared risk link groups,SRLG)的电力需求响应调度优化算法。根据电力通信网业务的分类,将需求响应业务进行业务优先级的分区定位,提出电力需求响应业务传输的信用值整形机制(credit-basedshaper,CBS),对不同优先级业务的传输调度机制进行描述。考虑电力通信网的共享风险链路组,对不同优先级业务调度路径的选择进行优化,实现所选路径的高可靠性。仿真结果表明,所提算法可以有效降低需求响应业务调度路径的SRLG综合失效概率和风险,平均节点处理时延较小,很好地保证了需求响应业务传输的可靠性和安全性。In order to reduce failure probability of multi-priority service transmission in power communication network and improve system reliability, this paper proposes an optimized scheduling algorithm for power demand response based on multi-priority services and shared risk link groups (SRLGs). By classifying power communication network services, the priority of demand response service is zoned and positioned. A credit-based shaper (CBS) mechanism for transmission of power demand response service is proposed to describe the transmission scheduling mechanism of the services with different priorities. Taking SRLGs of power communication network into consideration, this paper optimizes the selection of the scheduling paths of the services with different priorities, therefore achieving high reliability of the selected path. Simulation results show that the proposed algorithm can reduce comprehensive SRLG failure probability and risk of the scheduling path of demand response service effectively and has a relatively short delay, thus ensuring reliability and security of the transmission for demand response service.
