From July 14th to July 16th, 2023, Delta Power Electronics NewTechnology Symposium and Delta Power Electronics New Power System Summit Forum,hosted by Delta Group and organized by Huazhong University of Science andTechnology, was held in Suzhou Wujiang Tongli Lake Hotel. The meeting waschaired by Prof. Zeyuan Li, a foreign academician of the Chinese Academy ofEngineering, a member of the American Academy of Engineering, the director ofDelta's Power Electronics Science and Education Development ProgramImplementation Committee, and the director of Delta's Scholars ProgramImplementation Committee, and Prof. Yong Kang, the rotating executive directorof the Delta Power Electronics Science and Education Development ProgramImplementation Committee 2023, and a professor at Huazhong University ofScience and Technology (HUST). This meeting reviewed the results of theimplementation of the two programs in the past one year. Prof. Xing Zhang fromour school attended this meeting, and also attended this meeting were Prof.Zhen Xie, Prof. Jianing Wang, Mr. Fei Li, Mr. Qiang Chen, Mr. Ming Li, Mr.Hanyu Wang, and more than ten students from the Hengai Jingcheng team.

At the opening ceremony of the conference, Professor Li Zeyuan andMr. Cheng Chonghua (Founder and Honorary Chairman of Delta Group) deliveredspeeches. Prof. Li Zeyuan, foreign academician of the Chinese Academy ofEngineering and director of the Science and Education Program, said that in thenext two to three decades, we will see a large amount of renewable energyentering the power grid, turning it into a distributed micro-grid, which willbe assembled into a large power grid system; among them, a lot of powerelectronic equipment will appear in the smart grid and play an important role.Therefore, the establishment of a special project on power electronics for newpower systems by the Science and Education Program is not only to promote thecultural change of interdisciplinary cooperation in power electronics and powersystems, but also to have the foresight of the current technological innovationand research and development in the industry. Power Electronics New TechnologySymposium has gone through more than twenty years of spring and autumn, verygrateful to all the years of the previous sessions of academicians, professors,scholars, teachers and students involved in the symposium for the promotion ofthe development of the power electronics industry to make efforts. We lookforward to the collaborative innovation and contribution of the participatingstudents, faculty, and industrial R&D personnel across fields andindustries in the future development of smart grid and new power systems withpower electronics. Delta's Founder and Chairman Emeritus, Mr. Chung-Hua Cheng,said that in order to cope with the climate crisis, the construction of newpower systems based on new energy sources is an important way to promote aclean and low-carbon energy transition and help meet the dual-carbon goal,which is very much related to the development of the discipline and technologyof power electronics. With power electronics as its core technology, Deltacontinues to invest in product innovation and research and development toimprove energy conversion efficiency and promote energy conservation and carbonreduction. Integrating energy infrastructure solutions for renewable energy,energy storage, and EV charging is what the team is actively working on, and wehave worked to build distributed smart grids and energy storage solutionsaround the world to enhance the resilience of the power grid with technology inthe hope of taking action to do our part in the energy transition.

At the Delta Power Electronics New Power System Summit Forum, TangGuangfu, academician of the Chinese Academy of Engineering and director of theHuairou Laboratory, Wang Chengshan, academician of the Chinese Academy ofEngineering and professor at Tianjin University, and Dr. Ai Zuhua, seniordirector of Delta's Energy Infrastructure & Industrial Solutions BusinessGroup, shared their insights and insights on topics such as "DevelopmentPath for Clean Transformation of China's Power System under the Dual CarbonTarget", "New Distribution System and Power Electronics", and"Development and Synthesis of Energy Storage System Technology".Under the goal of China's power system clean transition development path","new power distribution system and power electronics technology" and"energy storage system technology development and synthesis" andother topics for wonderful sharing, and in the moderator Huazhong University ofScience and Technology Prof. Kang Yong, the moderator of the conference,interacted warmly with the guests on the spot. Experts believe that the energytransition is facing great challenges, and major technological breakthroughsare yet to be realized in the fields of renewable energy, intelligent energysystem, hydrogen energy and energy storage, and clean utilization of fossilenergy. The new power system needs to be cleaned through the power supply,power system flexibility, power system digitalization, power electronics"four" development, to promote energy transformation, change the modeof development, upgrading and restructuring of the power system.

At the meeting, Mr. Wang Hanyu of the team made a final report forthe youth project "Research on Fault Diagnosis Strategies of CascadedH-Bridge Converters for Grid-connected Direct-mounted Photovoltaic", whichwas established in 2021.

Since 2000, under the joint initiative of Mr. Chung-Hua Cheng, thefounder of Delta Group, and Prof. Zeyuan Li, an internationally renowned powerelectronics expert, foreign member of the Chinese Academy of Engineering, andacademician of the U.S. Academy of Engineering, Delta has set up the"Delta Power Electronics Science and Education Development Program,"inviting 10 key universities to participate in the program, Xi'an JiaotongUniversity, Huazhong University of Science and Technology, Shanghai University,Harbin Institute of Technology, Beijing Jiaotong University, Shanghai Jiao TongUniversity, and Hefei University of Technology, to promote the innovativedevelopment and talent cultivation of power electronics and electrical drivesand other related disciplines in colleges and universities; and from 2023onwards, to invite North China Electric Power University and Hunan Universityto join the program, to further explore innovative research in thecross-disciplinary fields of power electronics and power electronics-enablednew power systems. power systems and other cross-disciplinary innovativeresearch. The program includes supporting university professors to carry outscientific research, rewarding outstanding master's and doctoral students, andorganizing symposiums on new power electronics technologies and summit forumson new power systems with power electronics. Since 2001, we have also beenawarding outstanding professors and associate professors who are engaged ininnovative research on power electronics and power electronic new power systemsthrough the selection of "Zhongda Scholars" and "Zhongda YoungScholars Award", as well as organizing the Zhongda Scholars Expert Forum.
