Abstract: In this paper,a new capacity configuration model is proposed,which uses the typical 24 hours daily curve of meteorological factors such as wind speed and solar radiation as the basic data,and which aims is to make the daily output power curve of wind and solar complementary hybrid system as far as possible to close to the local load curve.In this proposed model,the installed capacity of wind and solar are taken as variables.Finally,a Wuhan meteorological station observation data of solar radiation,a wind tower data surrounding Wuhan and a regional electricity load data are used to analyze model feasibility,the analysis results verify the effectiveness of the proposed optimization configuration method.
