Measurment Evaluation And Complementarity Of Solar And Wind Power Potential In The Eastern Henan Region

In recent years,global issues like climate change,global warming,and the fossil energy crisis are becoming more and more severe.A clean energy revolution,mainly represented by solar and wind energy,has been set off worldwide.In the future,solar energy and wind energy will take an increasing proportion in the electricity supply.The research on solar and wind energy is crucial for their full and effective utilization.China has a vast territory and a large population.In addition to the large-scale promotion of solar and wind energy industries,the popularization of clean energy use by households is also a very important means,which has a non-negligible contribution to the increase of the proportion of national green energy.The power generation efficiency of solar energy and wind energy is mainly affected by the external meteorological environment,urban-rural difference,and floor height.Therefore,it is necessary to explore the influence of meteorological parameters on the power generation efficiency of domestic solar energy and wind energy.In this paper,the eastern Henan region,which is rich in solar and wind energy,is selected to compare the differences in the distribution of solar energy and wind energy and analyzes the influence law of meteorological,urban areas,rural areas,and floors on power generation.The main research contents and conclusions are as follows:（1）The solar power generation data and corresponding meteorological parameters of typical rural and urban areas in the eastern Henan region in different seasons are monitored.Pearson correlation analysis shows that the main factors affecting solar power generation are:total radiation,wind speed,air temperature,air humidity,and AQI.On this basis,the influence of meteorological parameters on the difference between urban and rural areas and seasons of solar power efficiency is further analyzed.It is found that the total radiation follows the law of high rural and low urban,the air temperature follows the law of high urban and low rural,the air humidity is high in summer and autumn,and AQI is high in winter and spring.Taking all factors into consideration,rural areas and autumn are more favorable places and seasons for solar power generation.The research also carried out regression analysis on the factors affecting solar power in each season.The overall test P value and independent variable test P value of the established regression model were both less than 0.05,with a high correction coefficient.Different models can be used to evaluate the solar power effect in this region.（2）Wind power generation data and corresponding meteorological parameters of typical rural and urban areas in the eastern Henan region in different seasons are monitored.Pearson correlation analysis shows that the main factors affecting wind power generation are:total radiation,wind speed,air temperature,air humidity,atmospheric pressure,and O₃ concentration.On this basis,the influence of meteorological parameters on the seasonal difference and the height difference of wind power generation efficiency is further compared and analyzed.The seasons have a similar effect on wind energy to solar energy.The total radiation and wind speed of an urban high-rise are greater than that of an urban low-rise,while the atmospheric pressure and air temperature are lower than that of an urban low-rise.The concentration of O₃ is similar at different heights.Considering the influence of various factors,urban high-rise,and spring are more favorable to wind power generation.The research also carried out regression analysis on the factors influencing the wind power generation voltage in each season.The overall test P value of the regression model and the independent variable test P value were both less than 0.05,with a high correction coefficient.The model can be used to evaluate the wind power generation effect in this region.（3）Kendall rank correlation coefficient was used to analyze the solar-wind complementarity between urban low-rise and high-rise at the same location and time.It was found that urban low-rise and high-rise have strong complementarity on a daily scale,while rural solar energy and urban wind energy have no obvious complementarity at the same time.By analyzing the contrast difference of meteorological parameters and the complementarity of solar and wind energy resources in the eastern Henan region,this paper constructs the evaluation model of solar and wind energy resources based on different seasons,which can provide a basis and reference for the optimization and complementary utilization of solar and wind energy resources.
