Grid-Forming Converters in Weak Grids – The Case of a Mediterranean Island

2019
The existing power network of a Mediterranean island is used as test bed for the study of grid-forming converter dynamics in weak grid conditions. The control scheme adopted for the converter falls in the category of the so called virtual synchronous machines (VSM). Particular attention is committed to the interaction between the converter controls and

Modelling VSCs connected to weak grids

2019
This paper addresses the oscillatory stability phenomena studied in the literature and reported by network operators in grid-connected VSC systems. Negative interactions have been observed at different frequencies in these systems, causing the tripping of power converters (e.g. wind turbines or HVDC applications). The interaction between the controller

The Stability Performance Enhancement of Grid-Connected Inverters in Weak Grid

The thesis presents an integrated estimation and control framework to enhance the stability, synchronisation, and fault ride-through capabilities of grid-following (GFL) inverters in critically weak grids. To overcome conventional Phase-Locked Loop (PLL) instability under high grid impedance, the research proposes a Modified Virtual Impedance-PLL (MVI ...
