To this end, we propose a novel variation-based complementarity metrics system based on the description of series' fluctuation characteristics from quantitative and contoured dimensions. From this, the complementarity between wind and solar resources in China is assessed, and the trend and persistence are tested.
Monforti et al. assessed the complementarity between wind and solar resources in Italy through Pearson correlation analysis and found that their complementarity can favourably support their integration into the energy system. Jurasz et al. simulated the operation of wind-solar HES for 86 locations in Poland.
However, for the regions with relatively poor wind and solar resources, such as central Tibet, eastern Sichuan, western Yunnan, Chongqing, Guizhou, Zhejiang, Guangdong, and Guangxi, the complementarity is relatively weak.
That previous study used Kendall tau correlation coefficients and the second Modern-Era Retrospective analysis for Research and Applications (MERRA-2) reanalysis dataset, showed that the worst complementarity between wind and solar is found in northwest China.
It can be seen from the spatial distribution that wind and solar resource complementarity is relatively high in northwest, northeast, and central China, while the complementarity in the southwest and southern areas of China is relatively low.
In conclusion, the proposed variation-based complementarity metrics system provides an effective tool for comprehensively assessing the complementarity among multiple energy resources.
To this end, we propose a novel variation-based complementarity metrics system based on the description of series'' fluctuation characteristics from quantitative and contoured
