Communication Network Optimization For Core Services Needs Of Smart Grid

With the continuous development of smart grid,the services carried by the power communication system is increasing day by day,which poses great challenges to the current communication network.Most of the services carried by the power communication system is related to the safe,reliable and stable operation of the power grid.If the fault occurs,it will bring huge economic losses.To research effective coping strategies,optimize the network of power communication system,and optimize the bearer routing of various services in order to improve the network performance and achieve the safe and reliable transmission of power grid information,so as to provide security for the safe and stable operation of the power grid.In this paper,the core services of the smart grid--WAPS communication services as the main research object,analyze the status quo of WAPS communication network,services characteristics carried by power communication network and various services requirements.In order to meet the real-time and reliability requirements of the core services,the network is optimized.The main contents are as follows:First,established the mathematical model of the optimal network topology design with the goal of minimizing the cost of network construction,constrained by the real-time,reliability and traffic balance of the WAPS communication networks.And use the improved genetic algorithm to solve.The greedy algorithm based heuristic operator is used to convert the infeasible solutions in the genetic algorithm into feasible solutions to improve the convergence speed of the algorithm.The simulation results show that this model considers the usage of network resources comprehensively,realizes the real-time and reliability,realizes the network load balancing and chooses the optimal path of working path and protection path for the service.Second,According to the requirements of real-time and reliability of the wide area protection communication services,an optimal path selection model with delay and link utilization as the minimum and reliability as the constraint is established,and the genetic algorithm is used to solve the problem.The simulation results show that this model considers the usage of network resources comprehensively,realizes the real-time and reliability,realizes the network load balancing and chooses the optimal path of working path and protection path for the service.Finally,the article summarizes and looks forward to the work of this paper,hoping that with the further study of the work,we can design a more powerful and perfect application service for the intelligent communication network.
