Analysis of demand side energy IoT communication channel requirements of integrated stations, equipment, and users

At present, due to factors such as high noise, impedance mismatch, transmission loss and time-varying characteristics in the power line environment, the data transmission rate of power line carrier communication is severely restricted. In view of this, this article first analyzes the power line communication transmission matrix, and carries out the hierarchical modeling of the power line carrier channel from the station transformer to the user and the home, and the demand analysis of the low-voltage hierarchical power line carrier communication channel, and constructs a comprehensive station transformer to the user With the hierarchical power line carrier communication channel model inside the home, it studies the communication performance requirements of different business layers in the power distribution link, which includes traffic demand analysis, real-time demand analysis and fee control business communication performance demand analysis. A large number of communication demand data indicators prove the feasibility of low-voltage hierarchical power line carrier communication in demand response services. Demand-side energy IoT communication channel demand analysis guarantees the reliability of download wave communication in a large number of application environments for new energy grid- connected equipment, which is of great significance for further channel characteristics research and communication technology performance evaluation.
