Forskning om energilagringsfrågor för China Southern Power Grid

In a move to bolster regional energy cooperation, the Mekong Institute (MI) delegation met with China Southern Power Grid Co., Ltd. (CSG) on August 12 in Guangzhou, …

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.

Which river basins feed the China Southern power grid (CSPG)?

b The map illustrates the river basins whose hydropower dams feed the China Southern Power Grid (CSPG). These basins are the Mekong, Nujiang, and Red (transboundary) and the Yangtze, Pearl, Qionglei and Southeast Guangxi Coastal river basins (QSGCRB). All riparian countries in which the transboundary basins ow are shown on the map.

How to simulate the long-term development of the CSPG's electricity system?

To simulate the long-term development of the CSPG’s electricity system, we used an open-source power system modeling platform (GridPath) 26, 53.

How to emancipate the grid from reliance on coal?

To emancipate the grid from its reliance on coal and achieve carbon neutrality, radical changes to the generation and transmission facilities are planned. This includes the expansion of solar and wind plants, as well as a massive expansion of the hydropower fleet that will add more than 32 GW of installed hydropower capacity.

Does intelligence contribute to the green development of grid projects?

Tables 8 and 9 report the robustness test results which show that intelligence has a significant contribution to the green development of grid projects under the linear model, which verifies that the results are robust.

Can renewables meet the double goal of decarbonizing the power grid?

Since the available capacity of wind, solar, and hydropower is almost entirely exploited, this suggests that the capacity of renewables is not enough to meet the double goal of meeting an increasing demand while decarbonizing the power grid.
