Quantitative analysis of sustained oscillation associated with saturation non‐linearity in a grid‐connected voltage source converter Open
The interaction between the voltage source converter (VSC) and weak grid causes a negatively damped or diverging oscillation (DVO). The diverging oscillation generally evolves into a sustained oscillation (STO) when governed by the nonline…
