Research and Developments in the Area of Power System Security

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 EXaMINE project in which the group is involved in the research focusing transient stability emergency control, better utilization of phasor measurements for power system control, and application of reinforcement learning to the same problem, and (b) OMASES project in which the group is involved in the research focusing on preventive transient stability assessment and control as well as voltage security assessment. A short historical overview of the research activities at the group in the field are introduced then more details are given on the developments achieved within mentioned projects as well as future research directions in the field of transient stability emergency control and application of reinforcement learning methods to power system control.
