Talk Title: Big Data Solutions for Real-World Problems: Data Science for Social Good
Speaker: Dr Arjumand Younus
Abstract: With data being the new oil there has been an unprecedented race to make most of this data for various knowledge discovery processes. Knowledge creation enabled via the scientific process however has an underlying goal to improve the human condition and the well-being of society. This has ultimately led to a theme within data science known as data science for social good whereby machine learning is applied to problems in healthcare, journalism, finance, agriculture, manufacturing etc.
This talk will explore 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 will have 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 will be provided.

Talk Title: A ddecision Support framework for the Assessment of Decentralised Energy systems
Speaker: Dr Ting Wu
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 decentralizsed 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.

Talk Title: Advanced Computational Techniques for Robust Power System Analytics
Speaker: Dr Tabia Ahmad
Abstract: The electric power system is witnessing significant transformations towards an integrated, active, and ubiquitously-sensed cyber-physical system. An abundance of multi-scaled data from phasor measurement units (PMU), point on wave (POW) measurement devices and digital disturbance recorders offers tremendous opportunities as well as scientific challenges to infer the state of the grid. Also, present day power systems in an attempt to mitigate climate change problems are increasingly moving towards more and more generation from sustainable energy resources which lead to intermittent and uncertain operations. Building on mathematical foundations and statistical analysis, this talk aims to provide an overview of data analytic tools in the modelling and operations of modern power systems.
The key highlights of this talk include 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 reports 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 is also outlined.

Talk Title: Unsupervised Data Mining Methods for the Analysis of the Impact of HRES Plant on System Stability
Speaker: Ms Ana Radovanovic
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 focusses 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 BSc and MSc degrees in electrical engineering and computer science from the University of Belgrade, Serbia. She is currently working toward the PhD degree at the Department of Electrical and Electronic Engineering, The University of Manchester, UK, in the areas of renewable energy sources and power system dynamics.
Talk Title: Data-Driven Protection Scheme for Superconducting-Based Electricity Grids
Speaker: Ms Eleni Tsotsopoulou
Abstract: The protection of Superconducting Cables (SCs) is considered a challenging task due to the quenching of the High Temperature Superconducting (HTS) windings. Specifically, under transient conditions, such as faults, when the current flowing through the superconducting tapes exceeds the critical current , the HTS tapes will automatically quench, presenting high values of resistance and reducing the fault current magnitude. Furthermore, it has been found that the presence of the fault resistance affects the quenching process, making the detection of highly resistive faults a difficult task. To address these challenges, the potentials of data-driven algorithms can be exploited for fault diagnosis of SCs. Specifically, 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 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.
