At the appraisal meeting, Prof. Yang Bin, vice president of Tsinghua University, attended the meeting and delivered a speech. Starting from the history of the project and the achievements of Prof. Sun Hongbin's research team, Mr. Yang highly praised Prof. Sun's team's keen exploration and craftsmanship of new technology, and expressed his gratitude on behalf of the THU for the support and assistance of the Chinese Society of Electrical Engineering, various appraisal experts and cooperating units for many years.

At the appraisal meeting, the members in the project team including Prof. Sun Hongbin and Associate Prof. Guo Qinglai of the EEA made work reports, technical reports and application demonstrations respectively, and reported the project situations to the Appraisal Committee in an all-round way. The project, led by Prof. Sun Hongbin, lasted 17 years. It applied modern artificial intelligence technology (AI) to power grid dispatching. He pioneered the implementation principle and architecture of "automatic operator (AO)" in complex power grids, broke through a series of key technical problems, developed the first "intelligent machine dispatcher (AO)" system in complex power grids at home and abroad, and achieved online application. The system can quickly and intelligently discover critical sections that endanger the security of power grid, formulate detailed rules of key sections online, locate key factors affecting the safety of key sections, provide dispatching decision information efficiently and accurately, and ensure the security and economy of power grid operation.

Prof. Sun Hongbin's Technical Report

On the basis of listening to the report of the project team, the experts of the Appraisal Committee highly affirmed the significant breakthroughs made by the project team in the field of combining power system with artificial intelligence and the significant benefits achieved in improving the security and economy of power grids. They also questioned and answered questions with the members of the project team on the related technical details.

Academician Zhou Xiaoxin, Chairman of the Appraisal Committee, presiding over the meeting.

After discussion, experts of the Project Appraisal Committee agreed that the project will change the mode of making extensive operation rules offline from "expert intelligence" to "artificial intelligence" to discover fine operation rules online, and realize a major leap from "automation" to "intelligence" in dispatching decision-making. The project, as a major breakthrough and symbol in the field of intelligent dispatching technology, guides the development and progress of intelligent dispatching technology at home and abroad. It has reached the international leading level as a whole.
