The construction of a new power system requires not only the technological progress of the power supply side, but also the support of advanced power grid technology. As an innovation base for China's advanced power grid technology and a research and development base for advanced equipment, State Grid Smart Grid Research Institute Co., Ltd. has long been committed to the research and development of UHV and flexible AC and DC transmission technology.

He Zhiyuan, chief engineer of the State Grid Intelligence Research Institute: In western China, wide-area DC interconnection of multiple energy sources can be used to achieve real-time power balance of high-proportion new energy power systems. In eastern China's deep-sea wind energy resource-rich regions, it is also necessary to realize offshore wind power transmission through flexible DC technology.Editor/Ma Xue
