Distributed Power Sharing Control for Islanded Single-/Three-Phase Microgrids with Admissible Voltage and Energy Storage Constraints

This article investigates power sharing and power quality improvement issues of islanded single-/three-phase microgrids (S/T-MGs) where both sources and loads are unbalanced. A hierarchical distributed control approach is proposed, which consists of 1) a phase-independent virtual synchronous generator (P-VSG) control used for primary control of distributed generators (DGs), 2) a distributed second...
