Speech Title: Frequency Control in Power Electronics-Dominated Power Systems: Challenges and opportunities
Abstract: Modern power systems are enriched with renewable power sources and power electronics which present great technical challenges and opportunities especially to their system frequency control and stability. On one hand, the increase of renewable energy sources (RESs) and inverter-based resources (IBRs) penetrations in modern power systems affected the frequency stability by reducing the total rotating inertia and increasing the uncertainties and variabilities in the generation side. This results in a higher active power imbalance and consequently higher frequency fluctuations inside each power region and higher variations in exchanged power between different power regions. On the other hand, the increase of inverter-based loads (IBLs) reduces the load-frequency relief which affects the stability and operation costs of modern power systems due to the need to procuring a more contingency frequency control ancillary services (FCASs). Besides, the modern frequency control systems are being converted to be based on new cyber layers which puts overall the power system frequency stability and security under some challenges that need to be considered in the future frequency control and protection approaches. Nevertheless, there are potential opportunities that could improve the frequency stability and security and accelerate the energy transition and power systems transformation, especially by considering new advanced control and computing systems and utilizing them properly. This keynote speech would discuss the different aspects related to power system control and security in modern power systems with high penetration levels of IBRs, IBLs, and RESs with focus on their impacts on energy transition and decarbonization plans around the globe.
