Multi-objective Dual-Route Planning Algorithm for Grid Communication Network

Abstract

In order to adapt to the construction of the new generation power system, it is urgent to make use of various controllable resources to build a new generation of comprehensive defense system of power grid security. In this paper, we aim to design a multi-objective dual-route planning algorithm for grid communication network. Firstly, we consider the network structure, site level and service load in the node and link risk model. On this basis, we calculate the overall risk equilibrium value of the network. Moreover, we also take into account the QoS performance to formulate the highly reliable dual-route planning problem with the optimization target of the network overall risk equilibrium value and the end-to-end communication delay. Then, we propose the multi-objective dual-route planning optimization algorithm to solve the problem. Simulation results show that the proposed algorithm has advance in terms of the balance of network risk and the performance of QoS.
