A general method for small signal stability analysis [PDF]
IEEE Transactions on Power Systems, 1998 This paper presents a new general method for computing the different specific power system small signal stability conditions. The conditions include the points of minimum and maximum damping of oscillations, saddle node and Hopf bifurcations, and load flow feasibility boundaries.

Sensitivity Analysis and Small-Signal Stability of Grid Following Converters
TecnoLógicas, 2022 This article presents a small-signal study, based on a sensitivity analysis, of a voltage source converter (VSC) operating as a grid-following device. This type of operation is standard for integrating distributed energy resources directly into a primary

Small‐signal stability assessment based on virtual regional eigenvalue
IET Generation, Transmission & Distribution, 2022 Small‐signal stability assessment (SSSA) plays a significant role in large‐scale power systems operation. Since the computational burden and unavailability of the detailed time‐varying model, it is practically difficult to use model‐based approaches to ...

Small-Signal Stability and Resonance Perspectives in Microgrid: A Review
Energies, 2023 The microgrid (MG) system is a controlled and supervised power system consisting of renewable energy (RE)-based distributed generation (DG) units, loads, and energy storage. The MG can be operated autonomously or while connected to the grid.

Singular Perturbation and Small-Signal Stability for Inverter Networks [PDF]
IEEE Transactions on Control of Network Systems, 2022 This paper examines small-signal stability of electrical networks composed dominantly of three-phase grid-following inverters. We show that the mere existence of a high-voltage power flow solution does not necessarily imply small-signal stability; this motivates us to develop a framework for stability analysis that systematically acknowledges inverter ...
