Multipath Routing Strategy of Integrated Energy Communication System based on SDN Architecture

The integrated energy system is a new energy system that coordinates a variety of energy subsystems such as electricity, cooling and heating system. While amount of renewable energy devices energy storage devices are allowed to be connected to integrated energy system. Therefore, the integrated energy system has more types of data flow and larger scale of topo. To solve the problem of large-scale real-time data communication in this system, this paper proposed a multi-path routing method based on the classification of data flows’ tasks. Besides, geographic information is considered in heuristic operator to accelerate the computation of routing. Finally, we verify the effectiveness of the proposed algorithm and model on different kinds of numerical examples.
