Techniques for on-line transient stability assessment and control
2000 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.00CH37077), 2002Transient security assessment (TSA) is becoming an essential requirement for the security control of power systems in the new utility environment. This paper describes the motivation behind the development of a new TSA tool and outlines the techniques used in TSA.

Probabilistic Transient Stability Assessment and On-Line Bayes Estimation
2011It is a well-known fact that the increase in energy demand and the advent of the deregulated market mean that system stability limits must be considered in modern power systems reliability analysis. In this chapter, a general analytical method for the probabilistic evaluation of power system transient stability is discussed, and some of the basic ...

A novel approach for on-line transient stability assessment
PowerCon 2000. 2000 International Conference on Power System Technology. Proceedings (Cat. No.00EX409), 2002This paper investigates the transient stability assessment for an on-line application. It uses sensitivity analysis to evaluate the preventive actions to improve the dynamic security of a power system when a transient stability problem is detected. For operation planning and operation of a power system, generation re-dispatch and load shed are the ...

Improved hybrid approach to transient stability assessment
IEE Proceedings - Generation, Transmission and Distribution, 2005The characteristics of the minimum transient kinetic energy of post-fault trajectories are studied in order to develop a tool for dynamic security assessment during the operation mode analysis of power systems. Using available commercial software a strategy for the transient stability study is introduced to enable harmless contingencies to be screened ...

Consideration of excitation control for transient stability assessment
Proceedings of IEEE International Conference on Control and Applications CCA-94, 1994Direct transient stability margin (TSM) prediction using the 'extended' equal-area criterion method is able to provide fast dynamic security assessment when used with the classical generator model. However, the latter model is found to be too crude for many practical engineering applications. The TSM prediction has previously been successfully extended

Transient stability assessment as boundary value problem
2008 IEEE Canada Electric Power Conference, 2008This paper proposes a method for transient stability analysis for multi-machine electric power systems. Different from existing methods, a minimization problem with boundary values is formulated for obtaining critical conditions for transient stability, where a new numerical integration method is developed by modifying the trapezoidal formula to solve ...

Numerical Simulation for Stochastic Transient Stability Assessment
IEEE Transactions on Power Systems, 2012There has been continuous development of techniques for assessing the transient stability of power systems in the uncertain environment. In this paper, a novel framework for stochastic transient stability assessment is proposed. The basic theory of stochastic calculus is first introduced to form the mathematical basis of the proposed approach.

Transient stability assessment and decision-making using risk
2018Since the recent chances in the electric power industry towards deregulation, the task of the power system operators has become more critical and challenging. The systems are being operated with smaller security margins while the building of new infrastructure is facing an increasing number of economic and environmental obstacles.
