CAP Research Roulette
Seminars run by PhD students and postdocs with the Control and Power Group
The Control and Power (CAP) Research Group is excited to be holding a recurring Research Roulette event in the upcoming academic year! We are looking for speakers who would be happy to talk about their research to others.
The event will take place every month in the seminar room of the Electrical and Electronic Engineering Department building. It is intended to be an opportunity for our cohort of MSc students, PhD students, and postdocs in the Control and Power community to share their research, get to know each other, exchange ideas, and learn from each other’s topics.
The format of the event is a 20-40 minute presentation followed by a discussion. This will be an excellent opportunity for you, as a speaker, to practice presenting your research, prepare for presentations related to ESA/LSR/conferences etc., and potentially receive constructive feedback from colleagues.
If you would like to speak at this event, please complete this form. Once you have expressed an interest in speaking at the event, we will be in touch with more details. We are confident that you will find participating in this event to be a positive and enriching experience.

Title: A Model Predictive Approach for Enhancing Transient Stability of Grid-Forming Converters
Speaker: Ali Arjomandi Nezhad
Venue: EENG 909B
Date and time: Wednesday, 13/03/2024, 11:10 – 12:00
Abstract: A model predictive control (MPC) method for enhancing post-fault transient stability of a grid-forming (GFM) inverter-based resources (IBRs) is developed in this work. This proposed controller is activated as soon as the converter enters into the post-fault current-saturation mode. It aims at mitigating the instability arising from insufficient deceleration due to current saturation and thus improving the transient stability of a GFM-IBR. The MPC approach optimises the post-fault trajectory of GFM IBRs by introducing appropriate corrective phase angle jumps and active power references where the post-fault dynamics of GFM IBRs are addressed. These two signals provide controllability over GFM IBR’s post-fault trajectory. The performance of the proposal is tested via dynamic simulations under various grid conditions and compared with other existing strategies. The results demonstrate significant improvement in transient stability.
Biography: Ali Arjomandi Nezhad received his B.Sc. degree from Amirkabir University of Technology, Tehran, in 2016 and his M.Sc. from Sharif University of Technology, Tehran in 2018.
