Research On Photovoltaic Power Generation System And Its Positive Impact On Rural Poverty Alleviation

With the development of the world,energy problem is that in today's world we need to have to go to solve the main problem.Non-renewable energy,like coal,oil etc.One day these energy will be dead,and now the environmental pollution is becoming very serious.These questions force people to change the energy structure,looking for new alternative energy sources.Renewable energy research and development more and more get people's attention.Solar energy as a renewable energy,its clean,economic,cover et.The advantages of high volume popular with everyone.For photovoltaic power generation technology research and the study now is more and more attention all over the world.Article mainly through the analysis of the overall structure of the single phase independent power generation system,using the MPPT technology or improving technology of solar photovoltaic cells of the output of the control to achieve its maximum efficiency.In control of the storage battery pile based on the output characteristics of the battery and related Bunsen properties,to carry on safe its charge and discharge control.In the inverter module,this article through to the entire power system main circuit topology,the topological circuit is obtained,the step-up(Boost)high frequency Boost chopper circuit transformation and single phase full bridge inverter circuit DC/AC inverter power frequency transformation way.Then from the topology of the independent power generation system mathematical model is established,and the choice of control strategy,determine the parameters for the system,detailed analysis,has carried on the simulation with MATLAB,the simulation results of careful analysis,finally realizes the independent power system security,reliable,economic plan.
