Core Viewpoint - The article highlights the significant advancements and innovations in Jiangsu's power grid construction, particularly through the "Yangzhou-Zhenjiang DC Transmission Project" and other high-voltage direct current (HVDC) projects, which enhance the capacity and efficiency of energy transmission in the region [1][3][5]. Group 1: Project Developments - The "Yangzhou-Zhenjiang ±200 kV DC Transmission Project" is nearing completion, with the Lingkou converter station in the final stages of installation and testing, aiming for operation by February 2026 [1]. - The "Baihetan-Jiangsu ±800 kV HVDC Transmission Project" has successfully integrated conventional and flexible DC technologies, delivering over 30 billion kWh of clean energy annually to Jiangsu, significantly increasing the share of clean energy in the grid [3][5]. - The "Yucheng Converter Station," the world's first HVDC hybrid cascade converter station, has implemented 14 innovative technologies, enhancing power distribution efficiency and enabling flexible power supply adjustments [4]. Group 2: Capacity Enhancements - The construction of the "Taizhou Fengcheng to Wuxi Meili 500 kV Transmission Project" has increased the cross-river transmission capacity to 6.6 million kW, facilitating the transfer of approximately 28.9 billion kWh of clean energy annually from the northern to the southern banks of the Yangtze River [7][11]. - The overall cross-river transmission capacity has been raised from 18.5 million kW to 25 million kW through various projects, enhancing the ability to accept external clean energy [11]. Group 3: Technological Innovations - The "Yangzhou-Zhenjiang DC Transmission Project" is the first in China to convert AC transmission to DC, increasing the transmission capacity from 500-600 kW to 3.6 million kW, nearly a sixfold increase [10]. - The introduction of "embedded" DC transmission technology addresses the challenges of high demand and saturated grid conditions in densely populated areas [8]. Group 4: Future Directions - The company aims to continue enhancing the power grid's capacity and efficiency, supporting the integration of renewable energy sources and ensuring stable power supply as Jiangsu enters a new era of high electricity demand [12][15].
