Wind-solar complementarity and energy storage

Do wind and solar energy systems exhibit a natural complementarity?

Complementarity of wind and solar energy systems Wind and solar energy exhibit a natural complementarity in their temporal distribution.

Why do wind power systems need interseasonal energy storage?

Consequently, wind power systems will face a greater demand for interseasonal energy storage. Given the constraints of coupling with chemical systems, stable power generation throughout the year is the optimal choice, as it can significantly reduce the investment required for expensive energy storage systems.

How does wind power affect energy storage systems?

Since wind power can still provide some electricity output at night, it effectively compensates for the inability of PV systems to generate power during this period. This significantly reduces the operational duration of energy storage systems and enhances the overall stability of the hybrid system. Fig. 10.

What is the optimal complementarity ratio between solar and wind power?

Hou et al. proposed a comprehensive method to evaluate the abundance, stability, and complementarity of solar and wind power generation, identifying an optimal complementarity ratio of 1:0.27 between solar and wind power in Ordos, China.

What is wind-solar complementarity based on energy fluctuation?

Shi et al. proposed a theory of wind-solar complementarity based upon energy fluctuation, utilizing the spectral analysis to identify annual distribution patterns of wind and solar resources and determine the optimal mixed ratio of wind and solar equipment.

Are wind-solar complementarities necessary for a hybrid energy system?

The inherent complementarity of wind and solar energy resources is beneficial to smooth aggregate power and reduce ramp reserve capacity. This article proposes a progressive approach to assess the wind-solar complementarities in Shandong province, China for the preliminary planning of hybrid energy systems.
