© 2020 IEEE. Cascaded H-bridge converters are widely used in the implementation of medium voltage static synchronous compensators (STATCOMs). This is because of the advantages of relatively high-power density and the improved utilisation of low-volta...

Single-phase consensus-based control for regulating voltage and sharing unbalanced currents in 3-wire isolated AC microgrids (2020)
Journal Article
Burgos-Mellado, C., Llanos, J., Espina, E., Saez, D., Cardenas, R., Sumner, M., & Watson, A. (2020). Single-phase consensus-based control for regulating voltage and sharing unbalanced currents in 3-wire isolated AC microgrids. IEEE Access, 8, 164882-164898. https://doi.org/10.1109/ACCESS.2020.3022488

A distributed control strategy is proposed to share unbalanced currents in three-phase threewire isolated AC Microgrids (MGs). It is based on a novel approach where, rather than analysing the MG as a three-phase system, it is analysed as three single...
