Informations- und Kommunikationsbeitrag zur Energiespeicherung von China Southern Power Grid
Das chinesische Energieunternehmen China Southwestern Power Grid hat in Nanning im autonomen Gebiet Guangxi die wohl erste, großangelegte Batteriespeicherstation
What is China Southern power grid?
China Southern Power Grid (“Southern Grid”) is one of China’s two major state-owned power distributors that serve five southern provinces: Guangdong, Guangxi, Yunnan, Guizhou and Hainan. The region has witnessed a rapid build-up of power generation capacity, from 275 GW in 2015 to 350 GW in 2020.
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.
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.
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 ).
What role do coal power plants play in the CSPG?
Coal power plants have historically been the dominant source of electricity for the CSPG (Fig. 1). Importantly, their role does not change significantly if grid decarbonization policies are excluded: in the Reference scenario (Table 1), coal still accounts for 33% of new capacity and about half of the generation mix in 2060 (Fig. 2).
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.
