10:00 am on May 30, 2021，By Graduate School of Shandong University、Sponsored by the Postgraduate Affairs Department of the Party Committee，Hosted by the School of Electrical EngineeringThe 61st (total 1050th) "Jixiafeng" postgraduate academic forum was held in the lecture hall on the fourth floor of the Electric Power Building on Qianfoshan Campus。This forum invited Dr. Li Huimin, Distinguished Professor of the School of Electrical Engineering of Shandong University，The theme of the lecture is "Open and interactive smart grid based on Internet of Things (AIoT) technology"。This forum is hosted by Professor Zhang Hengxu。

Dr. Li Huimin in this lectureforCountry2030YearCarbon peak, carbon neutral in 2060ofGoal, discussion了How to make full use of itincludesIEC61850 specification、Artificial Intelligence and Internet of Things Technology、Edge computing and cloud computingetc.Technology,ComeSupports new source loads、Distributed interactive new generation smart grid。First，Dr. Li briefly introduced his education work experience，And by summarizing the energy digitalization proposed by Huawei、Green electricity is everywhere、Full link efficient、Ten major trends in digital energy including AI support，Introducing the key points of current new smart grid research。Part 1，Dr. Li introduced IEC61850 and its applications，He said that problems such as traditional communication protocols and the difficulty of information sharing between existing networks and control centers determine the necessity of IEC61850 research，And introduces the application scope of IEC61850 in detail、Communication interface、Substation Configuration Language (SCL)、How to implement monitoring、Problems with the two client configuration methods of direct file transfer and service interface transfer，Enable on-site students to become intelligent based on SCL configuration、Have a certain understanding of automation engineering and smart grid information interaction，At the same time，Dr. Li also introduced the complete electrical intelligent solution based on IEC61850 and some of their research results，The students gained a lot。Part 2，Dr. Li focused on the application of artificial intelligence technology and deep learning in smart grids，Including the full cycle of data services and AI model optimization、Non-invasive power monitoring using deep learning、Data processing and analysis process based on RNN、Intelligent video processing system and its main functions、Deep Intelligent Video Processing Technology Architecture、Intelligent video monitoring of distribution cabinets、High voltage electrical appliance UV imaging analysis system、High voltage electrical appliance defect analysis, etc.。Part 3，Dr. Li introduced the Internet of Intelligence (AIoT) based on cloud technology，Explained the overall architecture and development model of AIoT platform development based on the existing Internet of Intelligence。Part 4，Dr. Li proposed some application prospects in developing interactive new power grids，Including intelligent rail transit power automation system and distributed energy management system (DERMS) based on the Internet of Intelligence，Finally, the practical application of DERMS is introduced through an actual running distributed energy case。

Free communication session，Students and teachers present asked questions on different issues，Includes data elements or modules in the power grid as logical nodesSpecific example of LN、IEC61850 requirements for CPU, etc.，Dr. Li explains one by one，Professor Zhang Hengxu also put forward his own opinions on the lecture content。This issue of the "Jixiafeng" postgraduate academic forum ended successfully with warm applause from teachers and students。
