(Photo by Xu Ke/People's Daily Online) China's first "wind-solar-thermal-storage integration" ultra-high voltage (UHV) project, the Longdong-Shandong ±800 kilovolt direct current (DC) transmission project, was put into operation on May 8. Here, we outline an optimized, phased pathway for integrating solar and wind energy into a globally interconnected and fully coordinated power system. Developed by the State Grid Corporation of China (SGCC), the project stretches 915 kilometers from. Recently, China's first grid-forming wind-solar-storage integrated system applied in substations for real-time power supply assurance -- the Houhai No. 3 (Chunhui Substation) Demonstration Project -- was successfully put into operation. Led by Shenzhen Power Supply Bureau and jointly developed by. China has pledged to peak carbon emissions before 2030 and achieve carbon neutrality by 2060, yet its long-standing reliance on coal-fired power poses significant challenges for the transition. In recent years, however, wind and solar power have expanded rapidly. By the first quarter of 2025, their.
