This note gives a survey of some research activities in the Stochastic Methods Group of the University of Liège, “Montefiore” Institute, in the area of power systems security assessment and control, those in which the author is directly involved. Current research activities in the field are conducting through several research projects supported by the European Union and include those within: (a...

The paper presents the efforts and results of a large consortium of European Industries, Research Centers and Universities involved in an EU research project named OMASES in the field of Power System Dynamic Security Assessment (DSA). The overall structure of an on-line DSA tool including TSA – Transient Stability Assessment, VSA – Voltage Stability Assessment, TS – Training Simulator and MS – ...

In this paper a Neural Networks (NN) is proposed for transient stability prediction. Transient stability of a power system is first determined based on the generator relative rotor angles procured from time domain simulation outputs. Simulations were carried out on a single machine infinite bus system by considering three phase short circuit fault on the system. The data collected from the time...

This work analyzes the advantages of Artificial Neural Networks applied in development of a technique for estimation rotor angle and speed, transient stability assessment and control in real-time in Synchronous Generator. Two multi layered feed-forward Artificial Neural Networks are used for this technique. One is used for the estimation of rotor angle and another for the estimation of rotor sp...

Deep learning-based transient stability assessment has achieved big success in power system analyses. However, it is still unclear how much of the data superfluous and which samples are important for training. In this work, we introduce latest technique from artificial intelligence community to evaluate significance used deep learning model assessment. From empirical experiments, found that nea...

This paper is concerned with fast determination of generationshedding in the transient emergency state of power system. A simple Procedure is first developed to calculate the critical partial energy of individual machine and the assodated partial energy margin. The partial energy function is then applied to the transient stability assessment of a power system subjected to a large disturbance. F...
