Objectives
Nowadays,
power systems are operating with lower and lower security margins. This
is due to the prioritization of the electricity market deregulation,
the load consumption increase, the difficulties to build new facilities
such as transmission lines and large power plants, etc. Consequently,
the vulnerability of power systems becomes a very important issue and
the probability of large blackout tends to increase, as confirmed by
the various incidents experienced in 2003. Therefore, mastering the
knowledge of different topics related to blackout inception and power
system instability has become essential for researchers and engineers
involved in power system planning, operation and control.
The aim of this course is to focus on mechanisms of blackouts, instability
phenomena, modeling and analysis tools, preventive and curative measures,
and finally service restoration. More precisely, it will cover the following
topics.
Phenomena and instability
mechanisms
Typical system degradation scenarios (faults, protection failure, cascade
tripping of overloaded lines, instability). Instability modes (angular,
frequency, voltage). Instability mechanisms and countermeasures explained
using simple examples (P-? curves, equal area criterion, governor control,
spinning reserve, maximum load power, generator limits, P-V curves).
Description and analysis of recent experienced blackouts (lessons learnt,
needs and trends).
System-wide monitoring
Wide area monitoring and control. Information and communication technologies
(ICT) to enhance control and protection. Visualization tools. Large-scale
monitoring of operating states,…
Real-time security
assessment
Preventive assessment of security margins with respect to angle and
voltage instability. State-of-the-art analysis methods for day-ahead
and real-time security assessment. Congestion management. Examples from
real implementations. New trends.
Emergency control
System protection schemes and defence plans for curative control against
large disturbances. Design principles. Generation shedding, underfrequency
and undervoltage load shedding. Examples.
System restoration
Overview of main strategies, load pick-up, black start capabilities,
design of restoration plans, real-time considerations. Examples.

Prof.
Dr. Rachid Cherkaoui (rachid.cherkaoui@epfl.ch)
Rachid
Cherkaoui received the M.S. degree in electrical engineering and the
Ph.D. degree from Swiss Federal Institute of Technology (EPFL), Lausanne,
in 1983 and 1992 respectively. From 1983 to 1987, he worked at Entreprises
Electriques Fribourgeoises (Swiss electrical utility) developing a state
estimator and security analysis tools for the HV transmission system
of that company. From 1987 to 1992, he joined the power system laboratory
of EPFL where he achieved his Ph.D. thesis in the field of optimal operation
topologies for distribution systems. In this respect, he was the recipient
of the ABB Swiss Award’83. Since 1983, he is leading the research
activities in the field of optimization and simulation techniques applied
to electrical power and distribution systems. Presently his main research
topics are electricity market deregulation, distributed generation and
storage, and, power system vulnerability mitigation. He is member of
IEEE, member of technical program committees of various conferences,
member of CIGRE task forces C5-2, and IEEE Swiss Chapter officer since
2005. He serves regularly as reviewer for different journals and conferences.
Dr. Cherkaoui is the author or co-author of more than 40 scientific
publications. At EPFL, he is lecturing two Master courses respectively
on power system dynamics and on electricity market deregulation and
co-lecturing one doctoral course on transient and dynamic phenomena
in power systems. He is also Exchange Students Coordinator for the electrical
and electronic engineering school of EPFL.
Prof.
Dr. Thierry Van Cutsem (t.vancutsem@ulg.ac.be)
Thierry
Van Cutsem graduated in Electrical-Mechanical Engineering from the University
of Liège, where he obtained the Ph.D. degree in 1984 and is now
adjunct professor. Since 1980 he has been with the Belgian National
Fund for Scientific Research (FNRS), of which he is now a Research Director.
His research interests are in power system dynamics, stability, security,
simulation, optimization and real-time control. His main recent contributions
are in the field of voltage stability and security. He is closely collaborating
on these topics with several Transmission System Operators: RTE (France),
Hydro-Québec (Canada), ELIA (Belgium), HTSO (Greece) and several
industrial partners (AREVA, Suez Tractebel). He has co-authored around
120 publications as well as the book “Voltage Stability of Electric
Power Systems”, Kluwer (Springer), 1998. He has been an active
member of several IEEE and CIGRE working groups. He acts presently as
Editor for the IEEE Transactions on Power Systems. He has been in the
scientific committee of several international conferences such as PSCC,
IEEE Power Tech, etc. At the University of Liège, he teaches
courses on Electric Power Systems. He is a Fellow of the IEEE and a
recipient of the Blondel Medal from SEE (France).
