Improved Droop Control in DC Microgrids via Voltage-Locked Loop Synchronization
Ognjen Stanojev, Jovan Krajacic, Enea Bianda +2
DC microgrids are low- or medium-voltage networks designed to connect and manage DC-based sources and loads. A key challenge in operating DC microgrids is maintaining the DC voltag…
Disturbance-Observer-Based Grid-Forming Control for Unbalanced Grids
Juho Määttä, Marko Hinkkanen, Tuure Nurminen +4
This article proposes a grid-forming control method for operation under unbalanced grid-voltage conditions. The method regulates the positive-sequence active power delivered to the…
A Feedback Stability Theorem for Frequency-dependent Compensation of Excess and Lack of Passivity
Pol Jane-Soneira, Gösta Stomberg, Ognjen Stanojev +2
This article studies the stability of feedback interconnections of linear time-invariant systems based on frequency-dependent passivity indices. Using these frequency-dependent pas…
Exploring Converter Control Duality in Microgrids: AC Grid-Forming vs DC Droop Control
Jovan Krajacic, Ognjen Stanojev, Mario Schweizer +3
Power electronic converters are fundamental building blocks of both AC and DC microgrids, enabling the integration of renewable energy sources, energy storage systems, electronic l…
Grid-Forming Characterization in DC Microgrids
Jovan Krajacic, Ognjen Stanojev, Mario Schweizer +3
DC microgrids are converter-based electrical networks that are increasingly being used in various applications, including data centers and industrial distribution systems. A centra…
The role of VSG parameters in shaping small-signal SG dynamics
Ferdinand Geuss, Orcun Karaca, Mario Schweizer +1
We derive a small-signal transfer function for a system comprising a virtual synchronous generator (VSG), a synchronous generator (SG), and a load, capturing voltage and frequency…
