摘要
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. © 2019, Power System Technology Press.
