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.

Are wide-area wind and solar resources complementary in Haixi?

Conclusions This paper explores the complementarity of wide-area wind and solar resources in Haixi from two perspectives: total output smoothing and source-load matching. It defines the first and second types of complementary indicators and analyzes four complementary modes: wind-wind, wind-solar, solar-solar, and solar-wind.

Which provinces have a temporal complementarity between wind and solar power?

At the annual scale, except for Tibet, Yunnan, and Sichuan, all other provinces exhibit a temporal complementary relationship between wind and solar power outputs (with negative Kendall’s correlation coefficients). Provinces with richer wind and solar resources demonstrate stronger temporal complementarity.

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.

What is the assessment framework for wind and solar power generation?

The assessment framework established a calculation model for wind and solar power generation and electricity demand in each province with hourly data granularity, incorporated two measurement indices, correlation analysis and fluctuation analysis, and divided the measurement analysis into two time scales: annual and seasonal.

Can global grid interconnection accelerate solar-wind transition?

Global grid interconnection represents a compelling pathway to accelerate this transition, particularly given the uneven geographic distribution of solar-wind potential (Fig. 1a).
