Economic Analysis And Optimal Design Technology Of 50MWp Photovoltaic Power Generation System In Inner Mongolia

As a kind of rich green renewable energy,solar energy is one of the most important clean energy in the future.Photovoltaic(PV)power generation is one of the main methods in the field of solar energy utilization,which transforms solar energy into electricity through photovoltaic effect.The Alashan Bayanhot area in Inner Mongolia Autonomous Region has abundant solar energy resources and good weather conditions,which is suitable for the construction of PV system.Therefore,this thesis has a research on the optimal design technology of PV power generation system taking the Alashan Bayanhot 50 MWp PV power generation system as the optimization object.The research work of this thesis mainly includes:First,The solar energy resources and meteorological data in this area are collected and analyzed in detail.The general situation of the local geology and the development status of the power grid are investigated,which provides the data base for the planning and design of the high benefit PV station in combination with the regional characteristics.Then,the optimal designs of solar panels,PV array operation,PV inverters,PV arrays,PV junction boxes and inverter rooms are carried out,respectively,especially the PV array model and solving algorithm considering local shadow effects,which can maximize the economic benefit of PV power generation system at the same time of meeting requirements of related PV power generation technology.Finally,the economic comparison of different PV optimal design schemes is executed and the economic calculation and comprehensive economic evaluation of PV power generation system from two aspects of project advantages and economic benefits is carried out.Meanwhile,the economic influence factors and its improvement measures of PV power generation system is also analyzed,which provides a reasonable basis for further promotion of PV power generation system economic benefits.The results of this thesis have certain guidance and reference significance for the optimal design and operation of PV power generation system.
