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: Stability Assessment Benchmark System Model

Speaker: Ali Arjomandi Nezhad 

Venue: EENG 909B

Date and time: Wednesday, 09/08/2023, 14:15-15:15 

Abstract: The main objective of the deliverable is to develop an open-source low inertia test system for stability analysis. There are several benchmark models in the literature. However, they either model the converters' behaviour for specific phenomena, or they lack modelling details of current saturation. To the best of our knowledge, this deliverable models, for the first time, the details of converters' behavior in a wide range of time scales. This includes the current controller, voltage controller, Phased Locked Loop, Active Power Control, and Secondary Frequency-Power controller, which range from the fastest to the slowest controllers. Additionally, the modelling also incorporates the current saturation, which shapes the behaviour of converters during big disturbances. 
 
The developed system is the modified IEEE fourteen-buses system. All resources of the original system have been replaced by renewable resources, which are either grid-forming or grid-following. All control loops of grid-forming and grid-following resources in addition to the secondary frequency control are simulated in the model. The model is simulated using Simulink/MATLAB software. The results of case studies suggest that the model can be used for various stability analysis. 

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. He is currently a Marie Curie Early Stage Researcher, funded by InnoCyPES project, and a PhD student at Imperial College London, UK. His research focus is transient stability assessment and enhancement of Inverter-Based Resource (IBR) dominant power systems.
