On-Line Transient Stability Assessment with EEAC
IFAC Proceedings Volumes, 1997Abstract A rigorously quantitative method for on-line transient stability assessment is prerequisite for coordination between economy and security of modem power systems. This method should identify all potentially unstable modes, and recognize dangerous reloading directions.

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

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.

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 ...

An Approximate Method for Probabilistic Assessment of Transient Stability
IEEE Transactions on Reliability, 1979Power-system transient-stability evaluation deals with the performance of the system when subjected to aperiodic disturbances such as faults, sudden loss of load or generation, and line switching. Under these conditions stability is lost when one or more generators fall out of synchronism with the rest of the system.

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.

NEW TECHNIQUES IN TRANSIENT STABILITY ASSESSMENT.
2012In this paper we present some results from Direct Methods of transient stability analysis. Results are stated briefly and the lengthy derivations omitted. The topics covered are: (i) energy functions for classical model and its extension to incorporate fast acting exciters; (ii) energy functions for structure preserving model with frequency and voltage
