Talk 2: Big Data Solutions for Real-World Problems: Data Science for Social Good
Abstract: This talk explored some potential application areas where data science for social good projects are explored and what role Big Data technologies play in such exploration. Fundamentally, we had a look at network representation learning techniques for soil properties data in an attempt to yield more accurate predictions for crop yields. Finally, an overview of other areas such as natural language processing was provided.

She was also a part of the Recommender Systems group at Insight Centre for Data Analytics in University College Dublin. She is the co-founder of the Dublin chapter of Women in Machine Learning and Data Science and is also actively involved with the Python Ireland community. She has a passion for projects belonging to the theme of data science for social good. She is the recipient of Google Women Techmakers scholarship for Europe, Middle East and Africa region. She completed her PhD in Computer Science in 2015 jointly from National University of Ireland, Galway and University of Milano-Bicocca, Italy; and her Masters in Computer Science from KAIST, South Korea.

Talk 3: A decision support framework for the assessment of decentralized energy systems
Abstract: With the energy revolution and the development of renewable energy, policy making in the energy sector should take into account the performance of different decentralized energy systems and make an informed choice for a more efficient, more reliable, cleaner and economically efficient future of electricity. The performance assessment of decentralized energy systems can be viewed as a multiple criteria decision-making problem with correlating criteria and alternatives. In this research, a decision support framework using the Evidential reasoning approach and Data Envelopment Analysis (DEA) is developed for the assessment of decentralized energy systems.
Biography: Dr Ting Wu is currently a Postdoc Research Associate at Alliance Manchester Business School (AMBS), The University of Manchester. She completed her PhD in Business and Management at AMBS in 2021. Previously she worked as an Assistant/Associate Professor in Shanghai Dianji University, after she obtained her first PhD degree in Engineering: Precise Instruments and Mechanics from Shanghai Jiao Tong University.

Talk 4: Advanced Computational Techniques for Robust Power System Analytics

Abstract: The key highlights of this talk included revisiting the statistical nature of noise encountered in power system measurement data and discussing its effect on the accuracy of power system analytics. Moreover, the talk also reported the effect of stochastic perturbations like loads/renewable energy (RE) injections on power system frequency fluctuations under ambient conditions using physics informed data-driven methods. On a parallel note, this increased uncertainty due to RE can aggravate the detection of cascading failures in power systems and may lead to catastrophic blackouts, thus hampering the reliability and security of electric supply. The potential of machine learning to predict such events early on at their onset, using field data and data from simulation test cases was also outlined.

Her research interests include power system dynamics, WAMS based analytics and signal processing techniques in power systems.

Talk 5: Unsupervised data mining methods for the analysis of the impact of HRES plant on system stability
Abstract: Stochastic production due to weather dependence is one of the main drawbacks of renewable energy sources (RESs). Hybrid renewable energy source (HRES) plants, comprising several renewable generation and storage technologies, have been recognized as a potential option for obtaining controllable power output from RESs. So far, the focus of the research has been on the economic benefits of HRES plants, with little attention being paid to the influence of HRES plant on system stability. The assessment of the contribution of HRES plant to the overall system behaviour is more complex than in the case of single technology-based power plants due to a number of HRES plant’s individual components having different static and dynamic characteristics. This presentation focussed on the suitability of clustering methods for identifying patterns in the performance of HRES plants in system stability studies, which represents a foundation for developing equivalent model of the whole HRES plant.
Biography: Ana Radovanovic received the B.Sc. and M.Sc. degrees in electrical engineering and computer science from the University of Belgrade, Serbia. She is currently working toward the Ph.D. degree at the Department of Electrical and Electronic Engineering, The University of Manchester, U.K., in the areas of renewable energy sources and power system dynamics.

Talk 6: Data-driven protection scheme for superconducting-based electricity grids
Abstract: A protection algorithm which combines signal processing techniques such as Stationary Wavelet Transform (SWT) and artificial intelligence techniques such as Artificial Neural Networks (ANNs) and Support Vector Machines (SVMs) is proposed for fault detection and classification on SCs. For this purpose, a simplified model of SC has been developed in Matlab/Simulink software and integrated in a power system which contains Synchronous generators (SGs) and Inverter-connected generators (ICGs). The two classifiers have been tested under different scenarios, encircling different transient conditions. The feasibility of the proposed algorithm was evaluated for real time implementation in order to assess the performance of the two classifiers in terms of their prediction speed. The obtained results confirm the effectiveness of the developed algorithm to detect faults occurred on the Superconducting Cables (SC) within short time and to remain stable for other transient events such as external fault and load switching events. Moreover, the ANN classifier has proven to be better for real time implementation.
