Modeling and controllers design for three-leg and four-leg grid-forming converters: A benchmark

We approach the modeling and a control strategy for three-phase three-leg three-wire and four-leg four-wire grid-forming converter under unbalanced conditions in an au-tonomous distribution network. In most cases, the analysis of three-phase AC power systems becomes simplified when the system is in three-leg three-wire configuration and perfectly balanced. However, one of the biggest challenges of...
