November 20, 2020 afternoon，By Graduate School of Shandong University、Sponsored by the Postgraduate Affairs Department of the Party Committee，The 44th (total 966) "Jixiafeng" postgraduate academic forum hosted by the School of Electrical Engineering was held in the lecture hall on the fourth floor of the Electric Power Building on Qianfoshan Campus。The keynote speakers of this forum are Professor Yue Dong of Nanjing University of Posts and Telecommunications and Professor Zeng Pingliang of Hangzhou University of Electronic Science and Technology，The topics of the lectures are "Research on multi-source information fusion and collaborative intelligent control of cyber-physical coupled smart grid" and "Key technologies of offshore wind power DC transmission system"。This forum is hosted by Professor Zhang Hengxu。

Report Begins，Professor Yue Dong introduced the "Networked Control and Smart Grid" research team co-led by Academician Xue Yusheng，And introduced the five-year science and technology projects。Professor Yue Dong first pointed out that social development and international trends require smart grids to carry out energy revolution and digital revolution，Research on safe, reliable and economical operation of smart grid under new characteristics faces severe challenges；Subsequently，Introduced the networked collaborative intelligent optimization control method innovatively proposed by the team，and "networking、The core idea of ​​​​research on "collaboration and intelligence"；Continue，Professor Yue Dong introduced the equipment research and development of networked cloud decision-making control system，By interacting with the "Cloud Intelligent Analysis Decision Support Platform and the "Source-Network-Load-Storage Networked Collaborative Control System"，Solving the "insufficient regulatory resources of low-inertia power grids with high proportion of new energy sources" under the integration of tokens、Operation problem of “increased stability risk”，Achieved the system’s “stability under small disturbances，Safety under large disturbances，The goal of "optimizing after large disturbances"。At the end of the report，Professor Yuedong warmly invites students attending the lecture to join his scientific research team，Contribute to the safe and reliable economic operation and development of smart grid。

Professor Zeng Pingliang’s report is divided into the following three parts: Development prospects of offshore wind power，Research status of offshore wind power transmission systems and several key technology prospects。First，Professor Zeng Pingliang introduced the continued decline in offshore wind power costs、Analysis of the distribution of offshore wind energy resources in my country、Explanation of the development prospects of offshore wind power by comparing the wind power AC transmission projects carried out at home and abroad；Next，Professor passes wind power grid connection technology、Fault protection technology、Introducing the research status of offshore wind power transmission systems using stability analysis technology。The current domestic wind power grid connection technology research focuses on high-voltage AC grid connection and high-voltage DC grid connection，He compared the characteristics and applications of high-voltage AC grid connection and high-voltage DC grid connection，In addition, a horizontal comparison of different networking methods during DC grid connection，Then it is concluded that "the ring mesh networking method is suitable for the delivery of large-scale and multi-location offshore wind power clusters、Conclusion that the radial networking method is suitable for relatively small-scale offshore wind power cluster outsourcing。Professor Zeng combined specific cases，Vividly introduces the stability problems that may arise from the interaction between wind farms and flexible-DC converters during the actual construction of offshore wind power flexible-to-direct transmission systems、The connection of the flex-to-DC converter to the AC power grid causes stability problems。Finally，Professor Zeng introduced lightweight technology、Joint fault ride-through technology、Stability analysis technology and the following corresponding preliminary research results，Converter valve lightweight technology、MMC DC fault ride-through technology。Finally，Professor Zeng Ping invites students in related research directions，And left contact information，Expressed the expectation to discuss with students in related fields，Common progress。

This issueThe "Ji Xia Feng" postgraduate academic forum came to an end with warm applause from teachers and students。
