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.

Does China have a smart grid?

China Southern Grid, one of the country's two major power grids, has been stepping up the construction of smart grids in recent years, as aging infrastructure and complex intermittent power flows are making the need to modernize power grids more critical.

What is the digital power grid white paper 2021?

In April 2021,China Southern Power Grid issued the “Digital Power Grid White Paper”, advocating for the digital grid as the optimal framework for accommodating the new type of power system.

Who is China Southern power grid (CSG)?

Policies and ethics China Southern Power Grid Co., Ltd. (hereinafter referred to as CSG) was established in 2002. CSG invests, constructs, and operates power networks in Guangdong, Guangxi, Yunnan, Guizhou, and Hainan provinces and regions.

Why did southern China's HVDC lines overpower its AC grid?

Southern China’s big HVDC lines overpowered its AC grid partly due to its thyristor-based converters, which require voltage support from the AC grid. CSG expects future HVDC projects to make greater use of newer, transistor-based voltage-source converters (VSCs), which manage their own voltage.

When was the first Green substation construction standard released?

In 2013, China Southern Power Grid released the first green substation construction standard document in the power industry, namely the “3C Green Grid Construction Evaluation Standard”.
