June 18，By Graduate School of Shandong University、Sponsored by the Postgraduate Affairs Department of the Party Committee，The 10th (831st overall) "Haiyou" doctoral academic forum hosted by the School of Electrical Engineering was successfully held in the lecture hall of the Electric Power Building on Qianfoshan Campus。This forum invites 2020 doctoral candidate Zhou Chenghan、Yu Yixiao is the guest speaker，Professor Zou Guibin is a guest commentator，Song Sili, Deputy Secretary of the Party Committee of School of Electrical Engineering, Shandong University、Song Jiping, Director of the Postgraduate Ideological and Political Office, attended the forum as a guest，President Song Lei of the Graduate Student Union of the College。

  The beginning of the forum，Zhou Chenghan’s topic is “Research on Active Distribution Network Differential Protection and Data Self-Synchronization Technology”，From the subject background and research status、Calibrated differential protection data self-synchronization method、Virtual three-terminal current differential protection method for distribution network、Report in four aspects: summary and outlook。He pointed out，When realizing differential protection data communication by reusing existing distribution network channels，Must bear expensive costs for reliable timing signals，This is also an important factor limiting the application of differential protection in distribution networks。His research topic focuses on the research status of differential protection of active distribution network，Carry out research from two aspects: data synchronization method and new protection principle，Achieved a series of outstanding research results。

  Yu Yixiao’s topic is “New energy power prediction technology in the context of dual carbon”，New changes in power grid form、Numerical Weather Prediction Technology、Report on three parts of new energy power prediction technology。Yu Yixiao talked about，Strong randomness、Large-scale grid integration of volatile new energy sources and electric vehicles、The large number of interactive devices such as distributed power supplies brings challenges to the power system，If the power balance becomes more difficult、Major changes in power grid support capacity、Distribution network operation control is more complex, etc.。Then she introduced in detail the research progress of numerical weather prediction technology and new energy power prediction technology，And pointed out the new challenges and future development of new energy power prediction technology。

  Zou Guibin combined the guest speaker’s report with guiding suggestions to the students at the scene，I hope students will change their attitudes、Proactively expand around the research direction of your own topic。The students present also asked the two speakers about their doubts，Both parties had in-depth exchanges and interactions。

  Song Sili makes summary comments。He pointed out，The current employment situation is grim，No matter students are preparing for employment，Consider further study for a Ph.D.，Everyone must make a good career plan。Make plans early，Only with ease，Easy response。

  To this point，This issue of "Haiyou" doctoral academic forum has concluded successfully，The guests took the stage to take a group photo。This "Haiyou" doctoral exchange and sharing forum provides a platform for current students to communicate，Sharing academic research through outstanding doctoral graduates，Inspire college students to stick to their original academic aspirations，Persistence，Making outstanding contributions to the national electric power industry。
