摘要：
In order to improve the resource utilization rate of the electric power communication network, reduce network redundancy, and meet the requirements of the power demand response business for the reliability of the transmission network, this paper considers the business characteristics of demand response and proposes a P-Cycle Protection Strategy for Power Demand Response Service Based on Message Awareness(DRPS-MA). Through the load balancing scheme to guide the network traffic, which can avoid the concentration of services in the network to certain specific links, effectively reduce network congestion, and optimize service routing. On the basis of ensuring network reliability, the joint optimization algorithm of working path and protection P-Cycles are used to solve the problem of path finding and protection of demand response services. Allocate working bandwidth and protection bandwidth for pending service requests, and maximize the use of network resources. Simulation results show that the proposed DRPS-MA algorithm can significantly reduce the redundancy and blocking rate of protection resources in the power communication network, and provide end-to-end rapid recovery for demand response services. © 2021, Power System Technology Press.
