Research On Intelligent Power Distribution Technology Combined With SDN And NFV

Intelligent power distribution is a new type of power control and distribution,which combines information technology and new energy technologie s,with highly intelligent,real-time interactive features.Flexible power communication network and intelligent power equipment is the key to realize intelligent power distribution.However,the current communication network protocol is complex,with a la rge number of electrical equipment but function fixed.These limit the development of power distribution.For this,this paper studies intelligent power distribution system combining SDN and NFV technology,in order to realize centralized management and c ontrol of power communication network,unify access of power business,and power function virtualization,so as to enhance the intelligent operation of power business.First of all,in view of the limitation of traditional power communication network,this paper designs intelligent power communication network based on SDN technology and the distributed hierarchical control mode,the algorithm of network resource optimization and utilization,and the creation method of power service virtual private network are researched.In face of the current electrical equipment which has different types and is not compatible with each other,this paper designed the detailed scheme of NFV intelligent power device.The function virtualized mechanism of equipment is studied,and the method of remote downloading and centralized upgrading of the virtualized functional model is proposed.Then,according to the demand of virtualized business function of NFV intelligent power device under the complex environment,this paper uses s imulink to create monitoring function simulation platform including photovoltaic inverter,electric vehicle charging pile and other complicated load.The virtual electrical parameter monitoring function which includes frequency characteristics,power chara cteristics,phase characteristics and virtual electric energy measurement error monitoring are simulated.In the end,this paper simulates the SDN intelligent power communication network by linux platform.And the adaptability of SDN network for power busi ness is simulated from network delay,real-time monitoring of traffic flow and virtual logical network divide.It proves the feasibility of the SDN smart power communication network for intelligentdistribution on the network structure and performance.
