This is a series of meetings to discuss topics related to the use of
Optimization and Operational Reseach techniques applied to problems in
energy. They are a mixture of reading seminars where some interesting
published work with be discussed, and informal lead discussion of
ongoing work, and more formal seminars.
"Mixed Integer Nonlinear Programming (MINLP) Solvers"
Notes for talk
Thursday 6th December 2012 at 10:00 in JCMB 1501
I will present the basic principles/algorithms for solving
MINLP problems. As well I will look at how some of
the open-source solvers implement these ideas in practice,
and how well-suited they are to the Blackout Islanding
problem in particular.

Optimal 84: EDF system summary
Friday 12th October 2012 at 11:00 in JCMB 6311
The Elecricite de France (EDF) energy system consists of aroud 60 thermal units - mostly
nuclear - and 50 hydro valleys. These generators have to be scheduled
optimally on a day to day basis. EDF has developed a proprietary
software tool to calculate a 24h ahead reference schedule, based on a
two-phase Lagrangian decomposition scheme. I will give an outline of the
algorithm and discuss its performance and weaknesses.
