Shaping Frequency Dynamics in Modern Power Systems with Grid-forming Converters
Carlos Collados-Rodriguez, Daniel Westerman Spier, Marc Cheah-Mane +2
In this paper, frequency dynamics in modern power systems with a high penetration of converter-based generation is analysed. A fundamental analysis of the frequency dynamics is per…
Analytic estimation of the MMC sub-module capacitor voltage ripple for balanced and unbalanced AC grid conditions
Daniel Westerman Spier, Eduardo Prieto-Araujo, Oriol Gomis-Bellmunt +1
In this paper, a mathematical expression to define the maximum and minimum voltage ripples of the modular multilevel converter (MMC) sub-module (SM) capacitors is proposed. Using t…
Improved current reference calculation for MMCs interal energy balancing control
Daniel Westerman Spier, Eduardo Prieto-Araujo, Joaquim López-Mestre +1
The paper addresses an improved inner current reference calculation to be employed in the control of modular multilevel converters operating during either balanced or unbalanced co…
