Title: Challenges and Solutions for Protection System in Power System with Inverter-based Resources
Abstract:
The transition to a net-zero energy system requires a massive change in the way that electricity is produced, transported and used; the power electronic converters are the core of this paradigm-shifting, and the control techniques used on them have a primary influence in the power system dynamic behaviour. It is well documented that the power electronic converter-based resources created new challenges from the protection system perspective. One of the challenges from the protection point of view is coming from the signature of the output current of inverter-based resource (IBR) during short circuit conditions. It differs from traditional rotational electrical machines during a short circuit. The semiconductor switching devices of the power electronic converter are intolerant to overcurrents, so the short circuit current contribution is limited to avoid damage to the switching devices, and during this limited operation, the output waveform can be nonsinusoidal. Additionally, the dynamic response of the PEC during fault conditions is highly dependent on the IBR programming impacting the voltage and current relationship at the point of connection. The IBR’s peculiar features affect its performance during fault conditions and the protection system at transmission and distribution. This keynote starts with an introduction of the IBR characteristics, control strategy and considering the pre-fauls performance and time frame after the fault. Discussion about the IBR transient rating and the protection are presented. The keynote is intended to present details of the challenges of traditional protection systems at the transmission and distribution level caused by the integration of IBR. The effects of the IBR performance of the protection are presented: traditional line protection scheme, traditional directional and non-directional overcurrent protection schemes, and negative and zero polarised directional protection. Off-line and real-time simulations are used to present the challenges. The keynote closes by presenting a comprehensive set of proposed solutions to increase the performance of the protection systems in power systems with high penetration of IBR.

Title: Unlocking the Potentials of Multi-Terminal DC Grids in Future Power Systems
Abstract:
High Voltage DC (HVDC) transmission is a long-standing technology with many installations around the world. Over the past few years, significant breakthroughs in the voltage-sourced converter technology along with their attractive features have made the HVDC technology even more promising in providing enhanced reliability and functionality and reducing cost and power losses. Concomitantly, significant changes in generation, transmission, and loads such as (i) integration and tapping renewable energy generation in remote areas, (ii) need for relocation or bypassing older conventional and/or nuclear power plants, (iii) increasing transmission capacity, and (iv) urbanization and the need to feed the large cities have emerged. These new trends have called for Multi-Terminal DC (MTDC) systems, which when embedded inside the AC grid, can enhance stability, reliability, and efficiency of the present power grid. The strategic importance of MVDC and HVDC grids is evidenced by the number of worldwide projects currently in their advanced planning stage, e.g., European “Supergrids” and the Baltic Sea project along with several projects in the US and China. This presentation is focused on opportunities brought by the MTDC grids and addressing the technical challenges associated with operation and control of those grids in future power systems.

Title: Energy Efficient Electrification Technologies for Buildings and Neighborhoods
Abstract:
On the way to economy decarbonization and energy efficiency improvement in the European Union (EU), buildings were targeted in the Energy Performance of Buildings Directive (EPBD), because they are responsible for roughly 40% of energy consumption and 36% of CO2 emissions. Nowadays, the design or retrofitting of buildings to achieve the highest class of energy performance is usually associated with the deployment of on-site energy generation, mostly employing photovoltaic systems. Another important decarbonization strategy for building stock is electrification of heating and cooling demands by means of heat pumps. Moreover, the revised EPBD requires the deployment of charging infrastructure for electric vehicles in buildings’ car parking, incl. possibilities of smart charging and vehicle-to-grid services to foster a more efficient integration of electromobility in the power systems. All these measures require extensive use of power electronics technologies, which will play a crucial role in the transition towards highly energy-efficient and decarbonized buildings, meeting one of the key objectives of the EU Energy Roadmap 2050. However, conventional Alternating Current (AC) power distribution cannot sufficiently accommodate all these challenges and has no room for improving energy efficiency. Hence, a paradigm shift to power electronics-enabled Direct Current (DC) power distribution technology can further push the energy performance limits by reducing residential electricity consumption by up to 20%. On the other hand, residential DC buildings should be coupled with AC utility grid via a bidirectional converter and are seen by the utility as a prosumer performing economic dispatch. Therefore, the application of DC distribution can significantly improve the resilience and demand-side flexibility and facilitate the energy arbitrage of the residential buildings, thus making them future-proof and compatible with energy transition targets.
Power Electronics Group of TalTech is one of the European leaders in research on energy-efficient electrification technologies for buildings and neighborhoods. This keynote will explore the essence of residential DC distribution technology, and provide insight into recent development trends, standardization, and challenges. Also, it will give an overview of the innovative technologies developed by TalTech Power Electronics Group to boost the uptake of the up-and-coming residential DC distribution technology, provide high efficiency and reliability of power supply, facilitate high flexibility by implementing plug-and-play features, and ensure the safety of residents.
