Modélisation et optimisation de l'interaction entre véhicules électriques et réseaux d'électricité : apport de la théorie des jeux

Abstract : This thesis is a study of the technical and economical interactions between electric vehicles and electrical networks. The recent development of electric mobility justifies the analysis of the potential impact of electric vehicle charging on the electrical networks, but also the possible support that these particular electric consumers could provide in future smart grids. For this reason, most of the results given in this thesis can be applied to a washing machine, a water-heater, a TV, as soon as these equipments become smart! When the decisions of flexible electric consumers interact, smart grids offers a unique exercise area for the tools of game theory. The interpretation is straightforward when the considered problem is strategic by definition, but these tools also allow to shed some light on other aspects: algorithmic coordination, information exchange, etc. Describing the benefits of the use of game theory in this context is the aim of this work, and is done according to three approaches: 1) algorithmic study: a charging algorithm is proposed to coordinate electric vehicles’ decisions in a given area of the electrical network. The analysis is conducted using the link of the algorithm with an underlying auxiliary charging game, which belongs to the class of potential games; 2) exchange of information: how should a flexible electric consumer give an image of his energy need to an operator of the electrical network? This part has a strong connection with Cheap-talk in game theory and quantization in signal processing; 3) strategic study: when groups of numerous electric vehicles – seen as fleets – coexist with individual vehicles. This is an application of the very recent concept of composite games. In these three studies, a particular attention is drawn to the case of rectangular charging profiles (at constant power and non-interruptible), which are very practical, but often ignored by researchers. Thorough simulations are conducted for a realistic French distribution network.
