Research And Design On Routing Planning Algorithms For Electric Power Communication Services

As an important infrastructure for carrying information exchange between power systems,power communication network serves all aspects of power system production and management,which is an important guarantee to ensure the safe,stable,economic and efficient operation of power grid.With the development of smart grid construction,more and more services are carried by communication network.Once the power communication network fails,it will directly affect the safety and stability of the large power grid.Therefore,how to make the service routing reasonably distributed is an important content in the field of power communication research.Because of the randomness of the fault,if the shortest route is chosen,a large number of services will be concentrated in some links,which will make these links become high-risk links.Therefore,the balanced distribution of services is listed as the optimization goal of power communication routing method,and the corresponding routing optimization algorithm is proposed,which can reduce the operational risk of power communication network,improve the reliability of communication network and the utilization rate of communication resources.It has practical significance for ensuring the safe,stable and reliable operation of large power grid.At the same time,there are many kinds of power communication services,and the requirements of different services are different,so it is necessary to provide differentiated services for different services.How to reasonably select the characteristics of different services,analyze the service characteristics and design relevant indicators to make the calculation of service importance more scientific is also an important issue.Therefore,based on the analysis of the current situation of power communication network and the characteristics of power communication services,this paper proposes a routing planning method based on the importance of power communication network services.According to the characteristics of various kinds of power communication services,the algorithm selects indicators that can reflect the differences of different services,uses the analytic hierarchy process to determine the service importance hierarchy evaluation model,and then ranks them according to the service importance.On this basis,a routing planning algorithm based on service importance is established.With the constraints of service bandwidth and delay,the problem is solved by reinforcement learning method,and an optimal path is found.The experiment proves that the algorithm can make the service allocation more balanced.Finally,this paper presents the requirement analysis and architecture design of power communication mode optimization simulation platform,gives the detailed structure design of visualization module and service routing module,introduces the functional use method of the platform,and applies the optimization algorithm proposed in this paper to the platform.
