Service Flow Differentiated Priority-driven Power Line Carrier Routing Algorithm

As one of the key infrastructures for smart grids in power systems, the power information acquisition system based on a power line carrier (PLC) realizes the exchange of information in the whole network. With the power grid’s scale increasing, the types of services and the amount of data grow fast. PLC faces the problem of constrained channel resources and a limited utilization rate of communication resources. This paper proposes a service flow-differentiated priority-driven PLC routing algorithm that considers the different transmission delay requirements of services with differentiated priorities. By introducing the price-rising matching of service flow priority, it can make routing link selection decisions for devices so that the differentiated delay requirements of different service flow requirements are guaranteed. Simulations show that the proposed algorithm improves the network load balancing degree and reduces the service flow delay.
