Appendix: Introduction to the China-Korea Academic Seminar on “Grid-Adaptive Renewable Energy Technology”

In November 2011, Professor Kang Chongqing from Tsinghua University was invited to give a lecture at Chonbuk National University, introducing the development of wind power in China and engaging in lively discussions with faculty and students. From October 22 to 23, 2012, more than ten Chinese professors and scholars from Tsinghua University, Northeast Electric Power University, North China Electric Power University, Shandong University, and Hohai University were invited to attend the first “Grid-Adaptive Wind Power Technology” China-Korea Academic Seminar held on Jeju Island, South Korea. More than 20 Korean scholars from Seoul National University, Chonbuk National University, Hanyang University, Lingnan University, and Korea University participated in extensive discussions and exchanges on topics such as wind turbine control and protection, wind power planning, and wind power measurement and control technology. The participants also visited the wind and photovoltaic power generation demonstration project in Hangwon, Jeju Island. This meeting laid a solid foundation for long-term cooperation between the two sides. In mid-December of the same year, Professor Yong-Cheol Kang, along with two other professors from Korea’s Chonbuk National University, visited several Chinese universities, including Tsinghua University, North China Electric Power University, Northeast Electric Power University, Shandong University, Shanghai Jiao Tong University, and Hohai University, and signed cooperation memoranda with each university.

Since then, the theme of the China-Korea Academic Seminar has gradually expanded from wind power to include renewable energy, including wind and photovoltaics. From 2012 to 2022, China and Korea have taken turns hosting the China-Korea Academic Seminar on “Grid-Adaptive Renewable Energy Technology” each year, totaling 11 sessions. The annual meeting schedule is as follows. Due to the impact of the pandemic, the 9th to 11th sessions of the China-Korea Academic Seminar were held in a hybrid online and offline format.

This forum is the 12th session of the series of academic seminars, with the theme “Extremely High Renewable Energy Penetrated Power System under Carbon Neutrality Target”. It aims to facilitate exchanges in renewable energy research through a bilateral academic conference, fully understanding each other’s experiences and advantages in the grid incorporation, operation, and planning of high proportions of renewable energy. The collaboration will provide strong support for the development of grid-connected and accommodating technologies for renewable energy on both sides, jointly promoting the renewable energy development goals of China and Korea.
