(2024) Dynamic analysis of the conductance-frequency droop control during current limitation. In [IEEE], 2024 International Conference on Renewable Energies and Smart Technologies (REST) (pp. 1-5). IEEE. https://doi.org/10.1109/REST59987.2024.10645363979-8-3503-5890-210.1109/REST59987.2024.10645363https://academica-e.unavarra.es/handle/2454/52745In inverter-based stand-alone microgrids, the P-f and O-V droop methods are frequently used to keep control of the microgrid voltage. However, in the presence of overloads or short-circuits, in which the inverter must perform a current- limiting strategy, the P-f droop becomes prone to transient instability. In order to remain stable under any possible overload or fault, the conductance-frequency $({G-f})$ droop is a promising alternative, however no analysis about its dynamic response has been carried out so far. This paper proposes a small-signal model of the system during current limitation, proving that the ${G-f}$ droop is also superior to the existing droop methods in terms of rapidity. Simulation results validate the theoretical analysis.application/pdfeng© 2024 IEEE. Personal use of this material is permitted.
