The power wireless network is an important part of the electrical communication network.The interconnection between the distribution terminal and the backbone communication network is realized by the power wireless network and the power distribution wired network,which is the key point to ensure the reliability of power supply,improve the operation efficiency and service quality of power grid.With the development of smart grid,the variety of electrical service and the demand for business are increasing.Researching a reasonable and effective resource allocation algorithm of power wireless network can not only provide differentiated,isolated services that satisfy the quality of service requirements for different businesses,but also improve the utilization ratio of network and reduce the cost of network operation and maintenance.At the same time,it is beneficial to the development of distribution communication network,and it is also of great significance to ensure the safe and effective operation of the whole power grid.First,aiming at the resource allocation problem of electric power private network,a resource optimization allocation algorithm for power wireless special network is proposed.Under the condition of ensuring the isolation of smart distribution network,the optimal allocation of virtual radio resources in smart grid is realized.First,according to the characteristics of the power wireless special network,a virtual system model of the power wireless special network is proposed.Then,a resource allocation optimization problem model is established based on factors such as network cost,profit,business isolation constraints,backhaul capacity constraints and quality of service constraints.Then,the optimization problem is solved by using the idea of genetic algorithm,and the optimal allocation of virtual resources is realized in the power wireless special network.Finally,simulation results show that the algorithm optimizes the operation of power wireless special network in terms of profit,energy consumption and quality of service.It provides an effective solution for the resource allocation and business isolation of smart grid.Then,considering the heterogeneity of the power wireless network and the real-time request of the service,a dynamic mapping algorithm for the virtual resource of the power wireless network is proposed.According to the real-time business requirements,a physical wireless network is mapped into a number of isolated,different services virtual networks.First,according to the characteristics of real-time demand of power wireless network,a dynamic mapping model is established,including time window model,physical network model,virtual network request andphysical network resource update mechanism.Then,a dynamic resource mapping model is established by combining the factors of node constraints and link constraints.Furthermore,the idea of load balancing is used to realize the real-time dynamic resource allocation.Finally,the simulation results show that the algorithm can achieve efficient dynamic allocation of power wireless resources and improve the acceptance rate of virtual network requests while guaranteeing the isolation between businesses and providing differentiated services for different businesses.
