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

The complementarity of solar and wind energy systems is mostly evaluated using traditional statistical methods, such as correlation coefficient, variance, standard deviation, percentile ranking, and mean absolute error, to assess the complementarity of the resources in the review.

When do energy sources exhibit complementarity?

The energy sources exhibit complementarity when one energy source (e.g., solar) fulfills the energy demand during periods of low output from the other source (wind) or even the absence of generation from one of the sources .

Can a wind-solar hybrid system improve 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.

Are wind and solar systems complementary?

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 .

Is there a complementarity between solar and wind sources?

The work of estimated the complementarity between solar and wind sources in several regions of Texas, USA based on metrics divided into three different categories: total generation (capacity factor), variability (coefficient of variance and Pearson correlation) and reliability (firm capacity and peak average capacity percentage).

Can wind-solar complementarities improve grid penetration?

The findings indicate that attaining optimal wind-solar complementarities can lead to achieving grid penetration at reduced storage capacity requirements, compared to scenarios focused solely on wind or solar power. Meanwhile, all other scenarios required comparatively similar storage hours.
