A Time-Sensitive Multi-Service Transmission Control Method with Integrated Communication Perspective for Smart Grid

The development of smart grids makes the demand for time-sensitive service carrying capacity of the power communication network more and more challenging. In recent years, the Power Integrated Communication Networks (PICN), joint multiple wireline or wireless systems, have brought more choices for business access and at the same time brought the complexity of deterministic transmission control. In this paper, we propose a multi-service transmission control method under the PICN. First, the multi-service transmission control architecture and models with time-sensitive constraints are constructed by combining the characteristics of the power business. After that, a routing algorithm based on Bidirectional A∗ (BA) and a flow scheduling algorithm based on Improved Quantum Particle Swarm (IQPS) algorithm are proposed. Simulation results show that the algorithms proposed in this paper can quickly find the optimized flow transmission path and set the Gate Control List (GCL), reducing the flow transmission delay by about 16.5%.
