Why is it important to assess photovoltaic power generation potential in China?
Clear spatial dislocations between PV power generation potential and population distribution and electricity demand. Accurate assessment of the photovoltaic (PV) power generation potential in China is important for the reduction of carbon emission intensity and the achievement of the goal of Carbon Neutral.
What is solar photovoltaic (PV) power generation?
Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.
What is the potential of solar power generation in China?
Chen et al. developed a comprehensive solar resource assessment system based on the GIS + MCDM method in 2019. This system was applied to the assessment of the potential of PV power generation in the countries under the “Belt and Road” initiative. The results showed that the PV potential of China is 100.8 PWh.
Where does PV power come from in China?
However, most of the PV potential in China is distributed in sparsely populated regions such as northwest and Tibet of China, and more than 95% of PV power generation in these areas is centralized PV power generation .
What is the PV power generation potential of China?
The PV power generation potential of China is 131.942 PWh, which is approximately 23 times the electricity demand of China in 2015. The spatial distribution characteristics of PV power generation potential mainly showed a downward trend from northwest to southeast.
How does a solar PV system affect grid stability?
Provided by the Springer Nature SharedIt content-sharing initiative The stochastic and variable nature of power generated by photovoltaic (PV) systems can impact grid stability. Accurately predicting the output power of a solar PV power generation system is crucial for addressing this challenge.
