Analysis of Modular Multilevel Converters under unbalanced grid conditions with different load current control strategies and Lagrange-based differential current control

Abstract

This work studies the performance of the Modular Multilevel Converter (MMC) under unbalanced conditions when the internal circulating currents are controlled to follow a reference value given by Lagrange-based optimization applied in the abc frame. The Lagrange-based current reference calculation is constrained to ensure that the MMC is providing constant… (More)
