How to assess complementarity between wind and solar power?
Assessing complementarity is a foundational work to combine wind and solar power to mitigate their fluctuations. Correlation coefficient is the most commonly used index to assess complementarity. But correlation coefficient mainly quantifies the synchronous and reverse correlations between wind and solar power.
What is the time-domain energy complementarity between wind and solar energy?
The time-domain energy complementarity between wind and solar energy has been assessed in many sites, and correlation coefficients such as Pearson, Kendall, and Spearman are the most commonly used indexes in quantifying and evaluating the complementary properties between wind and solar power.
Is complementarity between wind and solar power overestimated?
Further analysis reveals that the complementarity between wind and solar power would be overestimated once the fluctuation amplitude is ignored. Additionally, the proposed complementarity index can be used to optimize the installed capacity ratio of wind and solar power in a hybrid system.
Do distance and time scales affect wind and solar resources complementarity?
The effects of distance and time scales on wind and solar resources complementarity are assessed. Including hydropower in the mix increases the penetration rate of solar and wind power. In all months, daily variability in total power is always reduced by incorporating solar capacity.
