- Speech Title: Forecasting Methods and Their Applications in Electricity Markets
- Abstract: Forecasting spot electricity prices has become increasingly important for power utilities, particularly in the face of growing market volatility and uncertainty. While advanced methods, including machine learning, are being widely applied, using complex algorithms alone does not guarantee practically effective or reliable forecasting.
This talk explores the balance between interpretability and predictive performance, highlighting several representative models and their relevance to electricity market forecasting. These include regression-based approaches such as LASSO, Ridge Regression, and pcLasso, which builds on the strengths of the former methods to better capture structured information in the data.
We will also examine probabilistic forecasting approaches, including Quantile Regression, the quantile prediction model as its extension, and GAMLSS, with a focus on their ability to model uncertainty in key market variables and events such as price spikes.Finally, I will present selected findings on the integration of forecasting and optimization in electricity trading, emphasizing how predictive models can support decision-making under uncertainty. The presentation aims to provide perspectives that inform both practical implementation and further research in electricity market forecasting.

- Speech Title: Application, Development and Analysis of Low-Speed, High-Torque Axial Flux Permanent Magnet Generator for Fluid Machinery Renewable Energies
- Abstract: This presentation introduces the design, development, and performance analysis of a low-speed, high-torque axial flux permanent magnet (AFPM) generator. The proposed generator adopts a series-stator configuration equipped with air-cored windings and NdFeB permanent magnets, enabling direct-drive operation without a gearbox, compact structure, and high efficiency under variable-speed conditions. Experimental verification confirms its linear voltage–speed characteristics and stable electromagnetic behavior, achieving an efficiency range of 80% to 92% under various load conditions. The study further examines the generator’s modular structure and electromagnetic symmetry, demonstrating adaptability to multiple fluid machinery environments. By integrating digital-twin monitoring and predictive maintenance systems, this research aims to enhance the reliability and sustainability of distributed renewable energy systems. The findings contribute to advancing high-performance AFPM technology and its practical implementation in hybrid microgrid and net-zero energy applications.

- Speech Title: AI-Driven Sensor Fusion for State and Fault Diagnostics in Electrical Machines
- Abstract: Predictive maintenance of electrical machines using Artificial Intelligence (AI) represents a transformative approach to industrial reliability and efficiency. Instead of relying on scheduled maintenance or reacting to unexpected failures, AI-driven predictive maintenance enables early detection of faults and performance degradation through continuous data monitoring and intelligent analysis. This not only reduces downtime and maintenance costs but also extends the lifespan of critical equipment.A key factor in achieving accurate predictions lies in the proper design of the sensor system. Sensors serve as the primary data source, capturing essential parameters such as vibration, temperature and current signals. Defining the right sensor types, placements, and sampling strategies ensures that the collected data truly reflects the machine’s operational condition. Furthermore, sensor fusion— the integration of data from multiple sensors— enhances diagnostic accuracy by combining complementary information. Through AI algorithms, such fused data enables more reliable fault detection and classification, even in complex or noisy environments.
