Dynamic stability enhancement of power system using fuzzy logic based power system stabilizer
2013 International Conference on Power, Energy and Control (ICPEC), 2013The power system is a dynamic system and it is constantly being subjected to disturbances. It is important that these disturbances do not drive the system to unstable conditions. For this purpose, additional signal derived from deviation, excitation deviation and accelerating power are injected into voltage regulators.

Influence of Windfarms on Power System Dynamic and Transient Stability
Wind Engineering, 2006The interaction between bulk windfarm generation and conventional generation and its influence on network dynamic characteristics are investigated. A simple three-generator system having characteristics that may be considered representative of the major areas of the UK network is used for the dynamic studies.

Stability and nonlinear dynamics in power systems
IEEE Power Engineering Review, 1994Power systems are characterized by nonlinear dynamics, and unusual and unexpected behavior has been observed in both simple and complex networks. System behavior is expected to become increasingly complicated because of such factors as greater interconnection, the implementation of high-speed electronic power control devices and wheeling requirements ...

Dynamic stability analysis of an industrial power system
Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting, 1995An instance of poorly damped oscillations in computer simulation has been observed in the connection of an industrial cogeneration power system to the utility grid. An extensive investigation of this problem is presented. Both time-domain and frequency-domain analyses are used to determine the fundamental characteristics of the system, the major factor

Power System Steady-state Stability Criteria and the Jacobian of Dynamical Systems
IEEE EUROCON 2021 - 19th International Conference on Smart Technologies, 2021The paper is devoted to the theoretical problems of Power System stability (PSS) and plausible definitions, acceptable to distinguish the steady state stability (SSS) margin in the context of generalized theory of dynamic systems. The true criteria of aperiodic SSS are considered and comprehensively studied.

Evaluation of dynamic voltage stability of a power system
2004 International Conference on Power System Technology, 2004. PowerCon 2004., 2005Voltage stability is one of the major factors that dictates the maximum loadability of a power system. This paper investigates the dynamic aspect of voltage stability problem of a simple power system by considering the dynamic effects of both fast-acting and slow-acting devices.

Relative Dynamic Stability Regions of Power Systems
IEEE Transactions on Power Apparatus and Systems, 1970In this paper, making use of the well-established linearized equations of the synchronous machine and its control equipment, the characteristic equation of the system is developed. Using this characteristic equation, relative dynamic stability regions are mapped in the regulator parameter plane.

Power System Dynamic Stability Analysis and Stability Type Discrimination
2006 International Conference on Power System Technology, 2006In the static voltage stability analysis, the singular point of the power flow Jacobian is usually considered as the critical point. As this method does not take the dynamics of the components into account, the creditability of the results obtained are more or less affected.

Power system dynamic load identification and stability
PowerCon 2000. 2000 International Conference on Power System Technology. Proceedings (Cat. No.00EX409), 2002Proper power system load models are playing more important roles in power system stability analysis in today's stressed power systems. Different load models may cause a large difference in stability analytical results. Measurement based load modeling gives a closer look at the real power system loads and their dynamic characteristics.

Basics of power system dynamics and stability
To operate an electricity grid in a stable manner, the same physical principles must be considered for interconnected and islanded operations. This chapter contains a brief overview of some of the basic concepts in power system dynamics and stability with a special focus on islanded grids.Renner, Herwig +2 more
