Operational limits of four wires three levels NPC topology for power quality improvement in weak grids

In this paper, the limits of a Four-Wires Three-Level Neutral Point Clamped (4W-3L-NPC) inverter used as the only interface between a Hybrid Energy Storage System (HESS) supplied by a renewable energy system and a MicroGrid are under investigation. The investigation focus on the power division and p...

Summary:In this paper, the limits of a Four-Wires Three-Level Neutral Point Clamped (4W-3L-NPC) inverter used as the only interface between a Hybrid Energy Storage System (HESS) supplied by a renewable energy system and a MicroGrid are under investigation. The investigation focus on the power division and power exchange capabilities among a Redox Flow Battery (VRB) and a Lithium-Ion (Li-Ion) battery, the two energy storage systems investigated in the context of a MicroGrid. The final objective of this work is to define the limits of the investigated topology and prove its capacity to manage the power flow exchange between the HESS and a weak grid, as well as inside of the HESS.
