Probabilistic Analysis of Power System Small Signal Stability Region

2005 International Conference on Control and Automation, 2005
With the deregulation of power industry in many countries, the traditionally vertically integrated power systems have been experiencing dramatic changes leading to competitive electricity markets. Power system planning in such an environment are now facing increasing requirements and challenges because of the deregulation. The traditional deterministic

Small-Signal Stability Analysis of Multi-Terminal VSC-Based DC Transmission Systems

IEEE Transactions on Power Systems, 2012
A model suitable for small-signal stability analysis and control design of multi-terminal dc networks is presented. A generic test network that combines conventional synchronous and offshore wind generation connected to shore via a dc network is used to ...

Striving for small-signal stability

IEEE Circuits and Devices Magazine, 2001
In this article, based on Bode's definition of return ratio with respect to a single controlled source, the loop-based two-port algorithm and device-based gain-nulling are proposed for small-signal stability analysis. These two algorithms are complementary in terms of applicability, and they produce accurate stability information for single-loop ...

Small-signal stability analysis of delayed power system stabilizers

2014 Power Systems Computation Conference, 2014
This paper presents a stability analysis of power system stabilizers (PSS) for synchronous generators with inclusion of time delays. The paper shows that a time delay in the PSS feedback loop can improve the small-signal stability of a power system if the regulator gain is properly tuned.

Stability in Small Signal Common Base Amplifiers

IEEE Transactions on Circuits and Systems I: Regular Papers, 2013
This paper presents an analytical study of parasitic oscillation in video bandwidth common base amplifiers. We develop a series of progressively more complex small signal equivalent circuits based on the hybrid-π model [1], [2]. These circuits are developed such that the effect of each new parasitic element on circuit performance is evident.

A method for stability analysis of small‐signal microwave amplifiers

International Journal of RF and Microwave Computer‐Aided Engineering, 1998
This paper presents a method for analyzing the stability of small-signal microwave amplifiers with any topology. This analysis is performed using the Nyquist criterion and allows detection of the so-called odd-mode instabilities. The method is easily applicable by using commercially available microwave CAD. © 1998 John Wiley & Sons, Inc.

A review on the small signal stability of microgrid

2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia), 2016
Small signal stability is the key issue in the operation and control of a microgrid. For the small signal stability of an inverter-based microgrid, existing analysis methods mainly contain eigenvalue analysis using state-space models, impedance analysis based on impedance models and other nonlinear analysis methods.

Generator modeling in the context of small-signal stability

2016 IEEE Power and Energy Society General Meeting (PESGM), 2016
Modal analysis is the well-established method for investigating small-signal stability. Dominant states of a particular oscillatory or monotonous mode can be identified by linearizing the system's differential equations. Since generator oscillation is predominantly influenced by the speed deviation and the rotor angle, whereas other state variables ...

Small-signal stability monitoring using PMU

2014 IEEE International Energy Conference (ENERGYCON), 2014
The paper presents results of the research devoted to PMU-based power system small-signal stability monitoring. Proposed method allows tracking in-phase groups of generators and critical generators in the groups by analyzing low-frequency oscillations. Further developed, method is able to identify proximity to power system stability boundary.

Flexible tool for small signal stability analysis

2014 IEEE PES General Meeting | Conference & Exposition, 2014
This paper presents the development of a flexible tool for the calculation of the state matrix A of the power system. This program is called SIAM (Sistema Informatico para Analisis Modal — Computational System for Modal Analysis). The state matrix is obtained from the load flow solution data and from the dynamic model parameters employed.
