20.500.12556/DKUM-94275 Controllability-oriented method to improve small-signal response of virtual synchronous generators This paper presents a method for optimizing the inertia constants and damping coefficients of interconnected virtual synchronous generators (VSGs) using a genetic algorithm. The goal of optimization is to find a balance between minimizing the rate of change of frequency (RoCoF) and enhancing controllability. Five controllability-based metrics are tested: the minimum eigenvalue, the sum of the two smallest eigenvalues, the maximum eigenvalue, the trace, and the determinant of the controllability Gramian matrix. The approach includes the oscillatory modes’ damping ratio constraints to ensure the small-signal stability of the entire system. The results of optimization on the IEEE 9-bus system with three VSGs show that the proposed method improves controllability, reduces RoCoF, and maintains the desired oscillation damping. The proposed approach was tested through time-domain simulations. virtual synchronous generator inertia constant damping coefficient small-signal stability multi-objective optimization genetic algorithm virtualni sinhroni generatorji koeficient dušenja stabilnost malih signalov genetski algoritmi true false false MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/applsci © 2025 by the authors Članek v reviji 2025-08-12 12:14:43 2025-08-12 12:14:44 2025-08-13 03:12:48 0000-00-00 00:00:00 2025 0 0 21 str. iss. 15, [article no.] 8521 Vol. 15 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-06-22 2025-07-30 2025-07-31 621.31 245340419 10.3390/app15158521 2076-3417 applsci-15-08521-v2_(1).pdf applsci-15-08521-v2_(1).pdf 1 674810F2BD0827F48450C4990242BF66 ff59cbfbb8a42696f31cfbec22a145aada39c10b1ef44e517064cc9c9203e0b6 44a7d3af-7765-11f0-a28d-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=195143 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
