Reliability Dynamic Perception-based Power Line Communication Hierarchical Networking Method

With the large-scale access of distributed photovoltaic, controllable load, and energy storage devices to the low-voltage distribution network, the requirements for the transmission quality and processing efficiency of power line communication data are rapidly increasing. However, large access of high proportion power electronic components will introduce color noise, which will have a great impact on the channel environment of power line communication. This paper first constructs a multi-layer hierarchical power line communication networking architecture. Then, a reliability dynamic perception-based optimal subcarrier selection method is proposed to meet the high-speed transmission requirements of renewable power system services. The simulation results show that the algorithm has excellent performance in probability of selecting the optimal subcarrier versus iteration and data transmission efficiency.
