Number of wind-solar complementary solar container communication stations nationwide

Is there a complementarity between wind and solar resources?

To assess the complementarity between wind and solar resources, the observed daily wind speed (at 10 m) and sunshine duration data for 56 years (1961–2016) from 726 national meteorological stations are collected, and the corresponding solar radiation is calculated according to Eq. (1).

Are wind and solar energy resources complementary in China?

The results reveal that wind energy and solar energy resources in China undergo large interannual fluctuations and show significant spatial heterogeneity. At the same time, according to the complementarity of wind and solar resources, over half of China’s regions are suitable for the complementary development of resources.

Do wind and solar resources have a complementarity metric system?

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.

How do we evaluate the complementarity of solar and wind energy systems?

The review of the techniques that have been used to evaluate the complementarity of solar and wind energy systems shows that traditional statistical methods are mostly applied to assess complementarity of the resources, such as correlation coefficient, variance, standard deviation, percentile ranking, and mean absolute error.
