Session Title:
Transforming Power Grids: Renewable Energy Systems as Primary Sources
Brief Introduction:
As we move towards carbon neutrality, more and more renewable and sustainable energy systems will be installed across the globe. Power electronics is the key enabling technology for efficient and reliable utilization of renewable and sustainable energy. In this context, the conventional power grid architecture is transitioning to renewable-based distribution generation (DG) and power-electronic-dominant systems, where early retirements and replacements of conventional synchronous generators (SGs) are common. In conventional power grids, the frequency is governed by such SGs with large rotating inertia. By contrast, power electronics have fast dynamics and almost zero (low) inertia. That is, such inverter-based systems are becoming low inertia or inertia-less, making the system’s frequency less robust. Hence, it requires the power converters that act as the interface for sustainable energy and DG to provide advanced functions to maintain grid stability and controllability. That is, further technologies should be developed for renewable energy systems to transform power grids, where these systems, being the primary energy sources, should be much more active in grid regulation. Accordingly, in recent years, many have developed grid-forming technologies, e.g., virtual synchronous generators (VSGs)/machines (VSMs), virtual oscillator control (VOC), matching control, and others schemes such as virtual inertia control to enable power-electronic-based DGs to provide frequency support. This, to enhance the grid robustness, is demanding. At the same time, there are certain challenges to be addressed. Hence, this Panel Session on Transforming Power Grids: Renewable Energy Systems as Primary Sources is proposed to discuss recent advancements in grid-forming technologies for power-electronic-dominant grids. Preliminarily, progress in standardization and requirements of grid-forming technologies will be covered, as well as the stability modeling and analysis. Various grid-forming control strategies will be overviewed and benchmarked, and advanced operations like black start, transient stability control and system-level coordinative control will be discussed. Finally, the testing methods and scenarios will be briefed to further advance the technologies. All with a background of power electronics, and interested in modernizing the power grid are welcome.
