Energiespeicher-Sharing-Verhältnis des China Southern Power Grid
China Southern Power Grid Company constructs and operates the power grids in Guangdong, Guangxi, Yunnan, Guizhou, and Hainan provinces. As the power grid with the largest transmission volume from
Can China decarbonize the southern power grid by 2060?
Decarbonization of the Southern Power Grid in China is feasible by 2060 but requires converting a large cropland area to support solar and wind energy; expansion of hydropower will impact the transboundary rivers according to a power system optimization model set up for 2020–2060.
Is solar PV a cost-competitive source of energy in China?
In this case, the cost advantage of solar PV could be further amplified. The decline in costs for solar power and storage systems offers opportunity for solar-plus-storage systems to serve as a cost-competitive source for the future energy system in China.
Does utility-scale solar power have a viable grid penetration potential in China?
In this study, we developed an integrated technical, economic, and grid-compatible solar resource assessment model to analyze the spatial distribution and temporal evolution of the cost competitiveness of utility-scale solar power and its viable grid penetration potential in China from 2020 to 2060.
Can solar-plus-storage systems be a cost-competitive source of energy in China?
The decline in costs for solar power and storage systems offers opportunity for solar-plus-storage systems to serve as a cost-competitive source for the future energy system in China. The transportation, building, and industry sectors account, respectively, for 15.3, 18.3, and 66.3% of final energy consumption in China (5).
How many power grids are there in China?
As a hierarchical multi-area power system with multi-level dispatch centers, CSG governs five provincial power grids: Guangdong Power Grid (GDPG), Guangxi Power Grid (GXPG), Guizhou Power Grid (GZPG), Yunnan Power Grid (YNPG), and Hainan Power Grid (HNPG), which serve more than 252 million people (the basic overview is shown in Fig. 1 ).
Will China achieve full price parity with coal in 2023?
Nationwide parity is estimated to be achieved by 2023. Solar power in the North China, Northeast, East China, and Tibet grids is projected to achieve full price parity with coal in 2021, followed by the Central China, Northwest, and South China grids in 2023 (reference SI Appendix, Fig. S4 for the spatial distribution of the parity year).
