Analysis of the reasons why wind-solar complementary solar
By calculating the Kendall rank correlation coefficient between wind and solar energy in China, the study mapped the spatial distribution of wind-solar energy complementarity.
This study provided the first spatially comprehensive analysis of solar and Wind energy Complementarity on a global scale. In addition, it showed which regions of the world have a greater degree of Complementarity between Wind and solar energy to reduce energy storage requirements.
Accelerating energy transition towards renewables is central to net-zero emissions. However, building a global power system dominated by solar and wind energy presents immense challenges. Here, we demonstrate the potential of a globally interconnected solar-wind system to meet future electricity demands.
That said, the complementary use of wind and solar resources combined, also known as hybrid systems, is attractive. Hybrid systems are complementary even when availability values are not entirely complementary, called imperfect complementarity .
In the case of wind-solar hybrid systems, it was found that Complementarity can be enhanced through the dispersion of wind farms but not for solar energy. However, when considering wind farms, the feasibility must consider the requirement for long-distance transmission lines in this scenario.
