  1. The future of ICT for Power systems: emerging security challenges20052015 Session 3 Advanced system controls and ICT to improve prevention, protection and defense “Rapport” (L. Wehenkel, University of Liège, February 4th, 2005)

  2. 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 !

  3. 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

  4. 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 ?

  5. 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 ?

  6. Specific items raised • European efforts to deal with cyber-vulnerabilities • Non-intrusive technology migration paths • Improved use of PLC • SMART local (substation level) protection and control integrated into multi-level control structure • Question of our confidence in performances that may be reached with new technoly (GRIDSTAT, PSGUARD) • Public initiatives should stimulate stakeholders to build thrust

  7. 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 ?

  8. Homework ! • Please read the two following papers.
