  • Stability of inverter-based resources (IBRs) is essential right now due to the growing integration of renewable energy sources, such as solar and wind, into power grids; which displace conventional synchronous generators. Unlike synchronous generators that naturally provide inertia and help stabilize the grid during disturbances, IBRs lack this capability due to the fact that their controllers are normally in MPPT mode. As more IBRs are deployed, ensuring grid stability becomes increasingly complex, particularly during dynamic events like sudden shifts in generation or demand. Without focused research and development on advanced control systems and stability solutions, the rising dependence on IBRs could jeopardize grid reliability, potentially resulting in blackouts or other operational challenges.

    Moreover, the shift towards decentralized energy systems, including the increased use of distributed energy resources (DERs) like rooftop solar panels and energy storage, adds further complexity to maintaining grid stability. Research into IBR stability is crucial for creating new strategies, regulatory frameworks, and grid codes that facilitate safe and reliable integration. This research is vital for a successful transition to a low-carbon energy future, where renewable sources can be effectively and securely incorporated into the power grid without compromising stability and reliability.

    To address this pressing issue, I will offer research opportunities focused on the stability of inverter-based resources (IBRs). These projects will be designed to explore various aspects of grid stability in the context of increasing renewable energy integration. There will be approximately 5 vacancies for undergraduate students and 4 for master’s level students. These research topics will provide valuable insights and contribute to developing solutions that ensure a stable and reliable energy future. The topics are as follows:

    Undergraduate
    1) Dynamic state estimation of Grid-Following inverters
    2) Dynamic modelling of Grid Following inverters
    3) Dynamic Model of Grid forming Inverters
    4) Dynamic state estimation of Grid-forming inverters
    5) Dynamic modelling of Grid Following inverters in Typhoon HIL

    Master
    1) Inter-IBR oscillation
    2) Small signal stability analysis of a mixed GFM-GFL systems

    Students participating in these research projects are expected to:
    1) Build models of inverters using differential equations (without the use of industrial-grade software)
    2) Perform appropriate analysis to understand and assess the stability of inverter-based resources.
    3) Complete a thesis write-up based on their findings and contributions.

    Additionally, students are required to regularly work in the TD lab, where they will have the opportunity to collaborate with other PhD and master’s students who will be available to support and facilitate their research efforts.

    Please don’t hesitate to reach out if you’re interested in any of the topics mentioned above or if you’d like to have further discussions. You can contact me via email at husni.rois.ali@ugm.ac.id. I look forward to connecting with those eager to contribute to this important area of research!
