不同限电率下采用不同类型光伏支架的光伏电站投资收益率分析OA

This paper studies the impact of different types of PV brackets on the economy of PV power stations,in order to provide reference for PV power station owners to choose reasonable types of PV brackets.Firstly,the types of PV brackets are introduced.Then,based on an actual PV power station,the power generation capacity is simulated using PVsyst software,and compared with the on-site measured PV module power generation capacity.Finally,PVsyst software is used to study the economy of using fixed PV brackets,fixed adjustable PV brackets,flat single axis tracking PV brackets,and dual axis tracking PV brackets for the PV power station under different power curtailment rates.Suggestions for selecting PV brackets are also provided for PV power stations in various regions of China.The analysis results show that:1)According to the simulation results of PVsyst software,as the power curtailment rate increases,the total investment return rate and capital investment return rate of PV power station using four types of PV brackets will gradually decrease.When sorting the total investment return rate and capital investment return rate of PV power stations from high to low under different power curtailment rates,the corresponding types of PV brackets are flat single axis tracking PV brackets,fixed adjustable PV brackets,dual axis tracking PV brackets,and fixed PV brackets.2)By considering factors such as the footprint,power curtailment rates,performance of PV brackets,and investment return rate of PV power stations,it is found that fixed PV brackets are suitable for most parts of China,while fixed adjustable and flat single axis tracking PV brackets are suitable for North China and Northeast China.In addition,the dual axis tracking PV bracket not only has advantages in terms of PV power generation capacity,but also has significant disadvantages in terms of investment cost,operational reliability,and footprint of PV power stations.Therefore,caution should be exercised when using it.It should be noted that the selection recommendations for PV brackets in this paper have not been extensively validated in actual projects.They are for reference only.
