Bellizio, Federica (author), Cremer, Jochen (author), Strbac, Goran (author)This paper proposes a method to compute corrective control actions for dynamic security in real-time and quantifies the economic value of corrective control. Lowered inertia requires fast control methods in real-time to correct system operation and maintain system security when equipment fails. However, using corrective control beyond such...journal article 2022

Patel, Abhilash (author), Roy, Spandan (author), Baldi, S. (author)By increasingly relying on network-based operation for control, monitoring, and protection functionalities, modern wide-area power systems have also become vulnerable to cyber-attacks aiming to damage system performance and/or stability. Resilience in state-of-the-art methods mostly relies on known characteristics of the attacks and static...journal article 2021

Roose, Thomas (author), Lekić, A. (author), Alam, Mohammad Meraj (author), Beerten, Jef (author)This paper analyzes high-frequency interactions between a Modular Multilevel Converter (MMC) and High Voltage Direct Current (HVDC) grid resonances by studying their effect on the system stability. The recent appearance of converter-related instabilities due to high-frequency oscillations at the converter's ac side raises concerns about whether...journal article 2020
