Liu Zhaoxi, an outstanding master’s student of the 2023/2024 academic year from the Department of Electrical and Computer Engineering (ECE) at the University of Macau (UM). She comes from Shanxi Province, China, and developed a strong interest in the field of electricity since middle school, and this passion accompanied her all the way to the master’s programme in Electrical and Computer Engineering at UM. Liu obtained her bachelor’s degree from a normal university in the major of Electrical Engineering and Mechanical Automation. During her two-year master’s study at UM, she not only received the whole person development scholarship, but also made contributions to the optimization of power system operation and environmental sustainability through her innovative research on offshore wind power integration and power system applications.
Research on Offshore Wind Power and Power Grid Frequency Safety
Prof Zhang Hongcai, Liu’s supervisor, had close cooperation with of UM and power grid companies, which provided her with the opportunity to delve deeper into the field of offshore wind power. Liu was deeply interested in the topic of the impact of offshore wind power on power system frequency safety. To deepen her research, she proactively joined the State Key Laboratory of Smart City Internet of Things and became a member of the research team during her master’s study. This not only allowed her to get in touch with more cutting-edge technologies and innovative thinking, but she also overcame the numerous challenges in her research and efficiently completed her graduation project. Her research project focused on offshore wind power forecasting and power system frequency safety. She adopted advanced deep learning techniques, including Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU), combined with the K-means clustering algorithm, to successfully predict the day-ahead output curve of offshore wind power and provide effective suggestions for power grid dispatching. Furthermore, she also studied the impact of offshore wind power on power system frequency safety and determined the maximum proportion of offshore wind power connected to the grid while ensuring frequency safety. These studies they are of great significance for optimizing power system operation and promoting environmental sustainability.
Whole Person Development
In Macau, Liu experienced not only academic growth, but also the unique warmth of the city. She mentioned, “I particularly like the way people interact with each other here, it feels very warm and friendly.” Macau’s cuisine and pleasant climate were also impressive to her, becoming one of the important reasons for her to pursue further studies here. She represented the University of Macau to attend conferences such as the 2023 Power and Energy Panda Forum (PandaFPE) and the 2nd International Conference on Power Science and Technology (IEEE ICPST) in 2024, which not only provided her with opportunities to exchange with international peers and broaden her horizons, but also enriched her professional knowledge and insights. In addition to focusing on academic research, Liu’s extracurricular life was also vibrant. She was actively involved in various student organizations and clubs, including serving as the professional representative of the UM Postgraduate Association, the second-term Chinese Culture Ambassador, and joining the UM Sailing Club, UM Sports Volunteer Programme, UM National Flag Team, and the Community Safe Youth Leadership Programme. These activities not only enriched her extracurricular life, but also allowed her to make friends from diverse backgrounds. As a result, Liu was awarded UM’s whole person development scholarships, which highlighted her comprehensive development beyond academics.
Giving Back to Society
Liu also once served as a volunteer teacher in Heilongjiang for half a year, guiding middle school physics, and this experience further strengthened her determination to enter the field of education. For the future, Liu plans to join the teaching staff of Tong Nam School in Macau, and she looks forward to contributing her knowledge and experience to society. Liu’s story is a microcosm of the UM’s cultivation of all-round talents. Her experiences not only reflect the importance of academic research, but also showcase UM’s unwavering efforts in promoting the comprehensive development of students.
劉釗西是2023/2024澳門大學電機及電腦工程系的優秀碩士畢業生。自初中接觸電學以來，她便對該領域產生濃厚興趣，這份熱愛伴隨她走到了澳門大學電機及電腦工程系碩士課程中。劉釗西本科畢業於師範大學電氣工程及其自動化學科，在澳門大學的兩年碩士學習中，不僅連續獲得全人獎學金，更以其在海上風電整合與電力系統應用的創新研究，為電力系統運行的優化與環境可持續性做出貢獻。
海上風電與電網頻率安全研究
劉釗西的導師張洪財教授與電網企業有著緊密的合作關係，這為她提供了深入研究海上風電方向的機會。劉釗西對電力系統頻率安全穩定這一主題深感興趣，為了深化研究，她主動加入智慧城市物聯網國家重點實驗室成為研究團隊的一員。這不僅令她接觸到更多前沿科技與創新思維，為未來職業發展奠定堅實的基礎 。更讓她投身創新實踐，克服了研究中的重重挑戰，高效率地完成了畢業設計項目。她的研究項目針對海上風電預測及電力系統頻率安全展開，採用了先進的人工智能深度學習技術，包括長短期記憶（LSTM）和卷積門控單元（GRU），結合K聚類算法，成功預測了海上風電的日前出力曲線，並為電網調度提供了有效的建議。此外，她還研究了海上風電對電力系統頻率安全的影響，確定了一個在保障頻率安全前提下的最大海上風電並網比例。這些研究對於優化電力系統運行、促進環境可持續性具有重要意義。
全方位發展
在澳門，劉釗西感受到的不僅是學術上的成長，還有這座城市獨有的人情味。她提到：「我特別喜歡這裡的人與人之間的相處方式，感覺非常有人情味。」澳門的美食和宜人的氣候同樣讓她印象深刻，成為她選擇在這裡深造的重要原因之一。她曾代表澳大參加了2023年電力與能源熊貓論壇（PandaFPE）和2024年第二屆電力科學與技術國際會議（IEEE ICPST）等會議，不僅獲得了與國際同行交流的機會，拓展了視野，也豐富了自己的專業知識和見解。除了專注於學術研究，劉釗西的課外生活同樣精彩紛呈，她活躍於多個學生組織與社團，包括擔任澳大研究生會專業代表、第二屆中國文化推廣大使，並加入澳大學生會帆船會、澳大體育志願者計劃、澳大國旗儀仗隊、社區安全青年領袖計劃等。這些活動不僅讓她的課外生活變得豐富多彩，還讓她結識了許多來自不同背景的好友。劉釗西因此榮獲澳大全人發展計劃金獎，彰顯了她在學術之外的全面發展。
回饋社會
劉釗西還曾赴黑龍江擔任志願者，輔導初中三年級物理，這段經歷讓她更加堅定了從事教育事業的決心。對於未來，劉釗西計劃投身教育事業，將在澳門東南學校任教，並期待用自己的知識和經驗回饋社會。劉釗西的故事是澳門大學培養全方位人才的縮影，她的經驗不僅體現了學術研究的重要性，也展示了澳門大學在促進學生全面發展方面的不懈努力。
