Stability Modelling and Analysis of Converter-Driven Power System

The number of power electronics converters in electrical networks is increasing rapidly, as they are integral to all new grid-connected generation. While their fast control and switching enhance operational flexibility, the resulting dynamic interactions can compromise transmission system stability. To address this, it is critical to develop methodologies that identify potential stability and control risks before integrating new converter-based resources such as wind farms, STATCOMs, or HVDC links. This talk presents an impedance-domain analytical framework to quantify interactions between new plants and the existing network. It informs additional specifications for grid connection studies, including detailed technical assessments to mitigate stability risks. The framework supports MMC technology, control delay, system strength, and Fault Ride-Through (FRT) capability. Case studies from the research group of Professor Bikash Pal will illustrate the approach.Future research directions will also be discussed.
