Abstract
In this thesis, a controller achieving current tracking objective without knowledge of the grid parameters is developed. An estimated rotating reference frame (γδ -frame) is utilized. Within the control scheme, adaptive compensation terms facilitate the current tracking objective and, simultaneously, accounts for the unavailable grid voltage magnitude, grid frequency, and grid phase, hence eliminating the need for an additional measurement and feedback system for synchronization, such as a Phase-Locked Loop (PLL).
System frequency behavior using the controller in a high-renewable (low-inertia) grid indicates that the monitored performance metrics are significantly improved when compared to PLL-controlled, inverter-dominated grids.
