Multimachine System Transient Stability Improvement using Transient Power System Stabilizers (TPSS)
IEEE Transactions on Energy Conversion, 1986Power system stabilizers (PSS) have been designed and installed [1,2] to improve the dynamic (smnall signal) response of multimachine systems. This paper presents the theory and test results for improving the transient (large disturbance) behaviour of a multimachine system by supplementing the conventional PSS with a transient power system stabilizer ...

2021 11th IEEE International Conference on Control System, Computing and Engineering (ICCSCE), 2021
Nowadays, there is an increased concern for stability improvement in modern electrical systems, especially due to the use of distributed generation into the grids. Stability of power system is one of the main challenges to improve the power system efficiency.

Hybrid transient stability analysis (power systems)
IEEE Transactions on Power Systems, 1990The hybrid method of power system transient stability analysis, which combines the desirable features of both the time-domain simulation technique and the direct method of transient stability analysis, is presented. The hybrid method first computes the actual system trajectory using time-domain simulation, then evaluates the transient energy function ...

Transient response and transient stability of power systems
Proceedings of the Institution of Electrical Engineers, 1968The paper presents a case for correlating transient response with transient-stability limit of power systems. An elementary power system provided with fast acting voltage regulators using various feedback signals is analysed in detail. The effect of varying regulator gains on transient response is investigated with the help of gain-locus diagrams on a ...

Power System Restoration With Transient Stability
Proceedings of the AAAI Conference on Artificial Intelligence, 2015We address the problem of power system restoration after a significant blackout. Prior work focus on optimization methods for finding high-quality restoration plans. Optimal solutions consist in a sequence of grid repairs and corresponding steady states. However, such approaches lack formal guarantees on the transient stability of

Sequential transient stability assessment (power system)
IEEE Transactions on Circuits and Systems, 1989A sequential approach to the power-system transient stability assessment is presented and discussed. A reliable modified transient stability criterion is proposed. Simplified transient energy function expressions are derived, which enable a significant reduction of the computation time.

Power System Transient Stability Analysis: Formulation as Nearly Hamiltonian Systems
1983 American Control Conference, 1983A model of a power system yields \[ \dot q=M^{-1}p,\quad\dot p=KM^{- 1}p-\nabla G(q) \] which is defined earlier as a nearly Hamiltonian structure. Stability analysis of the equilibria is based on Hamiltonian theory. An example follows from power systems theory.

Transient Stability of Multimachine Power Systems
International Journal of Electrical Engineering & Education, 1976Transient stability of multimachine power systems is discussed using the concepts of modern control theory e.g. state variables, Lyapunov functions. The points discussed include the mathematical model, dimension of the state space, effect of damping on stability, validity of neglecting transfer conductances, also suggestions for further work in the ...

Transient Stability of Dissipative Power Systems
IFAC Proceedings Volumes, 1984Abstract Stability criteria for on-line analysis of transient processes in power systems are discussed. A method to approximate separation manifolds by energy surfaces of corresponding conservative systems is derived by using the theory of differential manifolds in the spirit of Its applications in classical mechanics. Closed form stability criteria,
