Abstract
With the large-scale power electronic equipment connected to the distribution network in the form of a new power system, the colored noise generated by power equipment will greatly reduce the efficiency of data transmission. The power line communication subcarrier grouping aggregation method features high transmission efficiency, excellent reliability, and high stability, which can improve the anti-interference and anti-noise performance of power line subcarriers. However, traditional subcarrier packet aggregation methods neglect the network topology changes and node service requirements, resulting in low adaptability of available subcarriers for power electronics scenarios. Therefore, we propose a value gain-based power line subcarrier aggregation method under colored noise. It can achieve adaptive colored noise awareness and dynamically optimize the subcarrier grouping aggregation. Simulation results demonstrate the excellent performance of the proposed algorithm in terms of availability and utilization efficiency.
