Research on frequency resource allocation model for power line carrier service of Integrated station, equipment and user

Abstract

At present, the requirements for smart and digital power grids continue to increase. As a unique communication method for power grids, power line communication has the advantages of low cost and wide coverage. As the business needs of stations, equipment, and users continue to increase, frequency resources are becoming more and more tight. , This article first analyzes the characteristics of different frequencies of power line carrier communication, and then proposes a broadband power line OFDM subcarrier allocation algorithm based on quantum genetic algorithm and simulates it. The results show that the algorithm has better convergence characteristics and higher resource allocation efficiency.
