The introduction of 5G into the electric power 4G wireless private network and the integration of 4 great significance for improving the efficiency of electric power business communication. Firstly application of G and 5G networks are of 5G in the power system and 4G and 5G networking methods is descirbed. Then, comprehensively considering the power own business, power business communication requirements, power base station construction costs, and base station operating costs, the power wireless private network 4G and 5G base station layout optimization models are constructed, and then optimize the layout of 4G and 5G base stations. Secondly, optimize the design and improvement of the coding and initialization population operations in the genetic algorithm, which greatly reduces the number of algorithm iterations, improves the convergence speed, and reduces the complexity of the model. Finally, the improved model solves the optimization model of power 4G and 5G base station layout. It can quickly give 4G and 5G base station optimization solutions to meet the requirements of power communication coverage and economy. Rationality and effectiveness of the proposed model and improved algorithm are verified by simulation examples.
