RESEARCH ON STRATEGIES FOR IMPROVING EVALUATE ACCURACY OF SOLAR ENERGY RESOURCE
摘要
Abstract
In the early development stage of PV power generation projects,it is necessary to evaluate solar energy resources.The accuracy of the evaluation directly affects the economic and feasibility judgment of the project,and solar irradiation is an important indicator for evaluating solar energy resources.This paper takes the solar irradiation data provided by three mainstream meteorological data databases as the research object.Firstly,an overview of the distribution of solar energy resources in China is provided.Then,by quantitatively analyzing the differences between the data in each meteorological data database and the data from the meteorological bureau,the optimal meteorological data database for PV power generation projects in each provincial administrative centers city is selected.Finally,a strategy for improving the accuracy of solar energy resource evaluation is proposed and validated.The research results show that:1)Overall,compared to the annual solar irradiation data provided by the meteorological bureau for each provincial administrative centers city,the data provided by SolarGIS and NASA meteorological data databases are larger,while the data provided by Meteonorm meteorological data database is smaller in most cases.2)Under the premise that values with a deviation rate below±1%are not corrected,both the temperate continental monsoon climate zone and the subtropical monsoon climate zone are suitable for using the Meteonorm meteorological data database,with data correction ranges of 1%to 4%.The tropical monsoon climate zone is suitable for using the SolarGIS meteorological data database,with a data correction range of 3%to 6%.The plateau climate zone can use either the SolarGIS or NASA meteorological data database,with a data correction range of 1%,and the arid climate zone can use either the SolarGIS or NASA meteorological data database,with a data correction range of 2%to 6%.关键词
