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.

How can solar-wind complementation improve the output power of PV power stations?

The stable output of PV power stations at the daily scale can be significantly improved through solar-wind complementation, particularly when there is zero output at night. Climate mainly affects the output power of PV power stations at a monthly scale, which makes it easy to summarize the regularity.

Can a scenario generation approach complement a large-scale wind and solar energy production?

Table 1. Details of complementary study. The scenario generation approach can effectively express the randomness and interdependence of VREs output [ 26 ]. The method is also developed to estimate how large-scale wind and solar energy productions could be potentially involved to complement each other.

Which type of complementarity is more pronounced in solar-wind mode?

Specifically, the first type of complementarity in the solar-wind mode is more pronounced. Regarding the timescale of the solar-wind mode, the correlation intensity varies from strong to weak in the following order: daily, monthly, and hourly.

Can solar-wind complementation improve low output levels during winter?

Solar-wind complementation can help improve low output levels during winter. Solar energy production fluctuates wildly at the hourly scale, and the regularity is weak. Therefore, the complementary effect of wind and solar is not very significant. 3.4. The Second Type of Complementarity

What is the difference between solar-wind and solar-solar complementary mode?

When striving for total output smoothing, the solar-wind complementary mode has a more significant effect than the solar-solar complementary mode. Specifically, the first type of complementarity in the solar-wind mode is more pronounced.
