About the research project
Renewable energy sources, such as wind and solar, utilise power electronic converters to efficiently integrate generated energy into the power grid. These converters must perform optimally under various grid conditions, such as unbalance, weak grids and harmonic distortion. Grid-side converters play a critical role in grid synchronisation and must be carefully designed to adhere to regulations and specifications for interconnected distributed generation. Grid-connected power converters operate in two main modes: grid-forming and grid-following. Grid-forming converters autonomously establish the grid voltage and frequency, providing essential stability during grid disturbances. In contrast, grid-following converters adjust their output based on external grid signals, frequently employing Phase-Locked Loops (PLLs) for output synchronisation. Transitions between these modes can lead to significant transient effects, such as overshoots and undershoots, due to their unique control mechanisms and the dependence on PLLs in the grid-following mode.
This project aims to understand and mitigate these transients to enhance system stability and reliability, particularly in grids with a high concentration of renewable energy sources. The project encompasses the derivation, modelling, simulation, prototyping, and experimental testing of innovative control strategies to validate and optimise performance. By improving the control of grid-connected power converters, this project contributes to the advancement of grid integration technologies for renewable energy systems, supporting the global transition to sustainable power systems.
