Research On Multi-Source Microgrid System Scheme Of 5G Base Stations Integrating Photovolatic

With the acceleration of social modernization,human’s demand for energy continues to increase,and traditional fossil energy is increasingly exhausted.Not only that,the burning of fossil fuels emits a lot of greenhouse gases and pollutants,aggravating global warming and ecological environment pollution.At the same time,in order to achieve high-quality economic development,the meeting of the Standing Committee of the CPC Central Committee emphasized that the construction of 5G networks should be accelerated.5G network is an important new infrastructure supporting the transformation of society to intelligence,networking,and digitalization.However,with the substantial improvement of the performance of 5G networks in all aspects,the power consumption of the main equipment in the communication base station has increased rapidly,resulting in a series of problems such as high operating costs,heavy environmental burden,and shortage of power supply capacity.In order to solve these problems well and quickly,speed up the deployment and construction of5 G networks,and explore the green and low-carbon development model of communication base stations,this paper proposes a multi-source power supply system for 5G base stations that integrates improved photovoltaic power generation technology.The specific work is as follows:(1)Considering the space constraints near the communication base station,improving the power generation efficiency of photovoltaic modules is one of the important ways to solve the problem.Aiming at the shortcomings of the traditional disturbance observation method that it is difficult to take into account both the tracking speed and the steady-state oscillation,an improved step size disturbance observation method is proposed.On the basis of the traditional disturbance observation method,variable step-size factors and three-point measurements are added,which can achieve fast track the maximum power point,and low oscillation at a steady state.(2)According to the original power system topology of the 5G base station,three microgrid system models are proposed,and a micropower supply scheme is proposed at the same time.Through theoretical analysis,it is proved that the micropower supply scheme has better power generation efficiency than the traditional string scheme.The power supply model of the microgrid system is established,and the objective functions,constraints,and evaluation indicators of the microgrid system are set up,which provides theoretical support for system simulation,optimization,and analysis.(3)Considering the reality that the single optimization objective of HOMER Pro software cannot meet the individual needs of many 5G base stations,a microgrid system configuration and component capacity optimization method based on two-level optimization is proposed,and the two-level optimization method is verified through case analysis.effectiveness.(4)Taking a communication base station of Guangxi University as the research object,simulate,optimize and analyze the microgrid system.Aiming at the problem of missing and abnormal load of original data,based on the characteristics of the data,it is proposed to use the random forest regression method to process the original data.By comparison,the random forest regression method can achieve better results.Based on the simulation results,the operation conditions,economic conditions,environmental protection conditions,and sensitive conditions of the microgrid system are analyzed respectively,and suggestions for the construction of the communication base station microgrid system are put forward based on the analysis results.The microgrid system was actually built at Guangxi University,and the difference between the actual data and the simulation data was analyzed to provide a reference for other researchers and engineers.
