Stability assessment and control design of future power electronic dominated grids require
efficient and adequate modeling methods. This article deals with modeling and stability …

This article presents a comparative stability investigation of grid-following (GFL) converters
with different advanced phase-locked loops (PLLs) and current control schemes based on …

This paper presents a new modelling framework, the Harmonic State-Space (HSS). The new
framework is intended for stability analysis of electromagnetic or control interactions …

This article deals with the harmonic resonance investigation of modern converter-dominated
power systems considering the asymmetric operation conditions. Initially, the complex …

Frequency domain models for power electronic circuits are either based on iterative
techniques such as Newton's method or linearised around an operating point. Iterative …

This thesis describes the transient oscillation control strategy developed for wind turbine
systems interconnected to a weak grid, which can cause nonlinear oscillations during the …
