The international community has reached a consensus to tackle climate change, reduce greenhouse gas emissions, and limit the global temperature increase to within 2°C, or even 1.5°C, of pre-industrial levels. Fossil fuel combustion is the primary source of carbon dioxide (CO2) emissions, with power generation accounting for more than 40% of China's total carbon emissions. Therefore, promoting the decarbonization of the power system is crucial to achieving the goal of carbon peaking and carbon neutrality in China. This involves transitioning from a traditional thermal power-based structure to a new energy-based structure and establishing a new type of power system through a phased approach
