Conception d'un outil d'optimisation dynamique du schéma d'exploitation du réseau de distribution d'électricité de SRD

Abstract : The French electrical distribution network was originally built to bring electricity from very large producers to consumers, but it has now become a place of multi-directional energy flows that rely on local production and consumption. Because of this new situation, the way of operating electrical networks needs to be renewed. In light of this, the local Distribution System Operator (SRO) of the French department Vienne and the different teams of the LIAS laboratory have worked together on the development of a distribution network configuration optimization tool. In this thesis the majority of the work was focused on the modeling part of the problem rather than on the development of new optimization methods. The industrial root of this project gave the opportunity to be very close to the reality of the available network data. Based on those observations,it was more consistent to use exact and precise optimization methods to solved simplified versions of the complex electrical network models.Thus a simple optimization model based on the minimum cost flow problem was developed, and a comparative study between the developed model and state of the art more complex one was led. This simple model was reformulated to become convex and quadratic and to reach better resolution time performances with the same solutions. This optimization problem was developed to take into account a time horizon factor into the optimization of the operation planning of the distribution network. The time horizon factor aim to represent the production and consumption variation over a selected period. Finally. because this model has to be integrated into a decision making helping tool that will be used by the DSO SRD several operational constraints were added into the optimization model. Several state of the art case studies arc presented to validate the model accuracy regarding existing methods. Simulation experiments were done on real networks data to show the applicability of the proposed optimization model over large scale case studies which correspond to the DSO SRO reality.
