Power system decarbonization pathway of China

Under the pressure of environmental issues, decarbonization of the entire energy system has emerged as a prevalent strategy worldwide.The evolution of China's power system will increasingly emphasize the integration of variable renewable energy (VRE).However, the rapid growth of VRE will pose substantial challenges to the power system, highlighting the importance of power system planning.This letter introduces Grid Optimal Planning Tool (GOPT), a planning tool, and presents the key findings of our research utilizing GOPT to analyze the transition pathway of China's power system towards dual carbon goals.Furthermore, the letter offers insights into key technologies essential for driving the future transition of China's power system.
