6 Frequently Asked Questions about “Analysis of wind-solar complementary situation of China s communication base stations”
Is there complementarity between wind and solar resources in China?
Compared with the literature, that used Kendall Tau correlation coefficients to assess the complementarity between wind and solar resources in China based on the observation data from 289 meteorological stations, the similarly spatial distribution of the complementarity is expressed in this study.
Is there a correlation between wind and solar energy in China?
By calculating the Kendall rank correlation coefficient between wind and solar energy in China, the study mapped the spatial distribution of wind-solar energy complementarity. Han et al. proposed a complementary evaluation framework for wind-solar-hydro multi-energy systems based on multi-criteria assessment and K-means clustering algorithms.
Is there a spatiotemporal complementarity between wind and solar energy resources?
Based on the data provided by China Meteorological Administration (CMA), this research explores the spatiotemporal complementarities between wind and solar energy resources. This paper nondimensionalizes hourly wind speed and global solar radiation data and employs several indexes to compare the smoothing effect with various combining scenarios.
Are wind power and solar energy correlated with load demand in China?
On the daily and monthly scales, except for the southeast region, the total output of wind power and solar energy is negatively correlated with the load demand in most regions of China, indicating that the characteristics of total output of wind power and solar energy are poorly matched with the daily and monthly characteristics of load.
Which country has the most complementarity between wind energy and solar energy?
At the hourly scale, the complementarity of wind energy and solar energy shows an increasing trend from east to west, with Qinghai, Yunnan and Xinjiang exhibiting the most pronounced complementarity.
What is the complementarity between wind and solar power generation?
The complementarity between wind and solar power generation is defined by the synergistic capacity of both sources to enhance electricity outputs and augment their reliability . Several indices have been introduced to assess the complementarity of wind and solar power generation across diverse temporal scales.
