XJTLU International Business School Suzhou (IBSS) Assistant Professor Jianyu Xu recently published a paper titled “Online Routing for Smart Electricity Networks under Hybrid Uncertainty” in top international journal Automatica. Dr Xu is the first author of the paper.
The paper focuses on the online routing optimal power flow (OPF) problems inherent within smart grids influenced by prediction errors and data integrity network attacks. The researchers developed an OPF model that considers segmented invariant load and generation, which can be evaluated using linear programming. The problem was then extended to an online environment where data is continuously observed and adaptive strategies are required to optimise the metric known as the regret function over time. The researchers combined state-of-the-art adaptive change-point detection methods to develop an online routing algorithm that preserves sublinear regret over both time horizons and the number of change points. The applicability and effectiveness of the proposed algorithm was verified through numerical experiments on a real-world smart grid, while the practical uses and advantages of the algorithm were further illustrated by application examples and extensive numerical comparisons.
Automatica has an impact factor of 5.944 for 2022-2023 and is ranked in the Q1 region of the Journal Citation Reports. The journal is organised by The International Federation of Automatic Control (IFAC) and is a leading archival publication in the field of systems and control. This field encompasses a broad set of topics, and is thriving both internally and in terms of its impact on other fields, such as communications, computing, biology, energy and economics.
Dr Jianyu Xu is an Assistant Professor at XJTLU International Business School Suzhou. His main research interests are in reinforcement learning, engineering quality and reliability, and industrial statistics. In 2012, Dr Xu received his BSc in Statistics from Peking University. He then went on to complete a joint PhD across two fields, Statistics from the Chinese Academy of Sciences, and Systems Engineering and Engineering Safety from the City University of Hong Kong. So far, Dr Xu's publications have been included in internationally renowned journals such as Automatica, the International Journal of Production Economics, and the European Journal of Operational Research.
Over the past year, IBSS scholars have published a number of papers in leading international academic journals at the UTD-24 and ABS 4/4* levels, including Management Science, the Journal of Operations Management, Information System Research, Production and Operations Management, the Journal of World Business, the Journal of Travel Research, the Journal of Retailing and Human Resource Management. IBSS academic staff have also been awarded a number of important research projects by the National Natural Science Foundation of China and the Humanities and Social Science Foundation of the Ministry of Education. The school is well on its way to realising its mission of becoming a top-quality research-oriented business school others can learn from.
