Simulation-Based Assessment of Weak vs. Strong Grids Compliance to the EMS Command for GFL Inverters

Year: 2026

Type: conference-paper

Abstract: This study investigates the impact of energy management system (EMS) power commands on grid-following (GFL) inverters and their role in enhancing grid stability within nanogrid configurations connected to grids of varying strength. Results demonstrate that GFL inverters cannot operate independently without a stiff grid-forming voltage reference; however, even in medium- or weak-grid conditions (characterized by low short-circuit levels), they contribute implicitly to voltage stabilization at the point of common coupling (PCC). This occurs through active power sharing, where the EMS-directed injection reduces current draw from the main grid, thereby minimizing voltage drops across the grid's Thevenin impedance. Despite these benefits, the stabilizing effect remains limited by the inverter's grid-following nature, which lacks autonomous voltage/frequency control, underscoring the critical role of grid stiffness.
