  • Speech Title: Flexibility And User’S Aggregations. Microgrid Configurations For Energy Communities: The Power Sharing Model
  • Abstract: Energy communities offer an effective model for facilitating renewable energy sharing and enhancing self- consumption within distributed systems. While traditional regulations accommodate virtual microgrids, they often lack fair and clear criteria for distributing shared energy and governing control. The speech proposes an innovative Power Sharing Model (PSM). It includes a comparative analysis of physical and virtual microgrids, presents the PSM's implementation, and reports on the first results obtained from the LAMBDA microgrid project. In the LAMBDA Lab flexibility is enhanced by a smart microgrid with PV, energy storage, vehicle to grid and smart solutions.
    The speech includes the Lab presentation and a comparison between physical and virtual microgrids; definition of the Power Sharing Model; implementation of a physical LVDC microgrid at LAMBDA; simulation and experimental validation using real consumption profiles and PV generation.
    Results confirm limitations of current virtual sharing models and demonstrate improved fairness, self- consumption, load-shifting, and stability using PSM. Physical tests at LAMBDA validate increased renewable utilization and effective real-time user engagement through Power Alert devices.
    The proposed PSM overcomes regulatory limitations of virtual communities, enabling fair energy allocation and increased renewable integration. Future work includes predictive models, scalability studies, and integration with EV charging strategies.

    • 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.

  • Speech Title: Affordability and Reliability of Sustainable Energy Systems
  • Abstract: A global sustainable future is being increasingly threatened by adverse environmental impacts of global warming. This is believed to be caused primarily by greenhouse gas emissions. Electricity generation and transportation are identified as the two major sectors responsible for green-house gas emissions. Governments around the world are, therefore, making considerable efforts to promote renewable energy and transition to electric vehicles to mitigate the adverse environmental effects. A significant growth in electricity generation is anticipated to meet the demands of population growth, economic growth, electrification of transportation sector, and consumption growth due to prosperity. The growth in demand must be accompanied by adequate investment in renewable energy generation technologies in order to ensure a reliable supply of electricity to the consumers. Lack of supply reliability results in excessive power outage costs to residential, commercial and industrial consumers, and “lost opportunity” costs for economic development. As renewable sources such as wind and solar are highly variable and uncertain, investment in supporting technologies, such as energy storage systems and smart monitoring/control of energy supply and demand are also necessary to maintain acceptable reliability. The investment needed in renewable energy resources and support technologies, to meet the target reliability, will substantially increase causing serious concerns on affordability of reliable power supply. This talk discusses the challenges in achieving reliable energy supply at affordable costs as we move towards a sustainable energy future.

    • Speech Title: Optimal Transient Control in Dual-Active-Bridge Bidirectional Converters
    • Abstract: Dual active bridge (DAB) converters are widely used in electric vehicles and DC transmission networks to connect two DC buses with different voltage levels. Their operation often requires rapid changes in the magnitude and direction of power. Phase-shift control is commonly adopted in dual-bridge converters. Under an instantaneous power command change, improper adjustment of the phase shift may lead to transient overcurrent and a long settling time. Therefore, this study focuses on regulating the phase-shift angles of different switching devices during fast power and direction transitions, enabling them to switch from one steady state to another as quickly as possible, without introducing DC bias current, overcurrent, or overvoltage. In this research, we present a detailed methodology for both conventional dual-bridge converters and resonant dual-bridge converters, covering investigations from open-loop to closed-loop control.

  • Speech Title: The Role of AI-Based Load Forecasting in Enhancing Power System Efficiency in the Philippines
  • Abstract: Electrical load forecasting is a well-established research domain that has been extensively studied, modeled, and applied. However, when examined within the context of developing power systems such as the Philippines, forecasting assumes a heightened level of operational significance. In such environments, forecasting accuracy extends beyond predictive performance, directly influencing procurement decisions, grid stability, reliability management, and operational risk. Even marginal forecasting errors may lead to tangible economic and system-level consequences. This presentation reframes load forecasting beyond algorithms and modeling techniques, emphasizing its role as a strategic intelligence function within power system operations. The discussion highlights the challenges encountered by utilities operating in dynamic, demand-sensitive environments, the operational implications of forecasting uncertainty, and the continuing importance of improving predictive reliability. In developing energy systems, forecasting accuracy is not merely a matter of prediction - it is a determinant of operational efficiency, economic stability, and system resilience.

  • Speech Title: Analysis of the Effect of Salt Pollutants on Insulator Degradation and Evaluation of the Effectiveness of Epoxy Resin and Rtv Sir Based Protective Coatings
  • Abstract: Power transmission and distribution system insulators function to isolate live and unlive parts. In Indonesia, outdoor insulators are generally made of ceramics and glass, which have weaknesses in humid and polluted conditions. Pollutants on the insulator surface and wet weather increase leakage current, which causes losses in the form of heating and insulation failure. The solution to insulator resistance to humidity and pollutants is hydrophobic coating. This study examines the effect of RTV silicone coating, epoxy resin, and air humidity on leakage current, voltage distribution of chain insulators in clean and polluted conditions, and the effect of pollutants on insulator performance. Laboratory experimental methods show that the leakage current of the insulator before being coated is in the range of 196.9 μA - 968.2 μA, after being coated with RTV silicone in the range of 92.5 μA - 645.3 μA, and epoxy resin in the range of 93.3 μA - 548.8 μA. The average reduction in leakage current by silicone RTV coating is 48.2%, and epoxy resin is 44%. Leakage current increases with air humidity and the weight of pollutants attached. The analysis shows that the coating worsens the voltage distribution, as evidenced by the increase in the flatness factor of the voltage distribution in polluted and humid conditions.
