The future of ICT for Power systems:
emerging security challenges
20052015
Session 3
Advanced system controls and ICT to improve
prevention, protection and defense
“Rapport”
(L. Wehenkel, University of Liège, February 4th, 2005)
Urgent needs and R&D Challenges
Applicability of advanced technologies ?

Maturity of technologies ?
Hardware (wires, measurements, computers…)
Middleware (methodologies of integration, of deployment)
Software (multi-area monitoring and control algorithms)

What are the migration paths ?
In terms of costs and R&D needs ?
In terms of delays ?

Adequacy from a “regulatory” viewpoint ?
Who will decide that it will happen ?
How to establish that it should ?
Trans-border issues !
How to improve system control ?
Replace and/or complement human decision making by
automatic procedures
Improve information used for monitoring and control




Accuracy/reliability/security
Temporal resolution(s)
Horizontal integration (i.e. cross-border)
Vertical integration (i.e. generation, distribution, consumers)
Improve models and algorithms for control design




Data collection, data mining, data driven modeling
Methods from (stochastic) optimal control theory
Models of multi-area and multi-level control
Integrate the ICT layer into the modeling and design process
On the distributed/dispersed
nature of end-users
Load

50% is highly dispersed
Generation

increasing part is becoming dispersed
Exploit this dispersed nature


To do smooth and robust ‘anytime’ control
As a resource for ‘better’ emergency control
If yes,


What are the economic values and costs ?
Who pays and who wins ?
Flexible transmission systems
Can we get rid of Kirchhoff Laws ?
Can we develop (and deploy) control
algorithms for re-routing power flows
automatically, with enough d.o.f. ?
Do we know how to coordinate MW
routing and end-user control ?
Specific items raised
1. European efforts to deal with cybervulnerabilities
2. Non-intrusive technology migration paths
3. Improved use of PLC
4. SMART local (substation level) protection and
control integrated into multi-level control
structure
5. Question of our confidence in performances
that may be reached with new technoly
(GRIDSTAT, PSGUARD)
6. Public initiatives should stimulate stakeholders
to build thrust
Conclusion
7th Framework Call (to be published)
How to take advantage of power
system physics and cybernetics
in order to fight against
cybernetic and physical threats ?
