Can a complementarity metric be used to optimize a hybrid wind-solar power system?

Compared with correlation coefficients, the proposed complementarity metric can be used to optimize the installed capacity ratio of wind and solar power and assist in selecting the specific components of a hybrid wind-solar power system, further adjusting the complementarity degree between wind and solar power.

Can a complementarity index be used to optimize wind and solar power?

Additionally, the proposed complementarity index can be used to optimize the installed capacity ratio of wind and solar power in a hybrid system. The proposed complementarity metric contributes to a better and more accurate understanding of the complementarity between wind and solar power.

How to assess complementarity between wind and solar power?

Abstract 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.

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.

Does complementarity of wind and solar energy affect system reliability?

The complementarity between wind and solar energy is significant on the monthly time scale. Spain W, S CCA hourly, monthly, yearly Wind and concentrating solar power plants can be used as base energy in the study region. Poland W, S PC 15 min Impacts of complementarity of solar and wind resources on system reliability are investigated.

What is wind-solar-thermal power bundling?

Wind-solar-thermal power bundling is an important scheme for integrating renewable power generation into the power system in China . In addition, China also plans to build ultra-high voltage (UHV) transmission lines to realize the cross-regional transmission of large-scale renewable power generation.
