Повний текст джерелаThe objective of this thesis is to develop and study mathematical models of economical exchanges between energy suppliers and consumers, using demand-side management. On one hand, the suppliers offer time-of-use electricity prices. On the other hand, energy consumers decide on their energy demand schedule, minimizing their electricity bill and the inconvenience due to schedule changes. This problem structure gives rise to bilevel optimization problems.Three kinds of models are studied. First, single-leader single-follower problems modeling the interaction between an energy supplier and a smart grid operator. In this first approach, the level of details is very high on the follower’s side, and notably includes a stochastic treatment of distributed generation. Second, a multi-leader multi-follower problem is studied from the point of view of the best response of one of the suppliers. Aggregators are included in the lower level. Two new resolution methods based on a selection of Nash equilibriums at the lower level are proposed. In the third and final part, the focus is on the evaluation of noncooperative equilibriums for this multi-leader multi-follower problem.All the problems have been studied both from a theoretical and numerical point of view

Повний текст джерелаElectricity storage capacities are still negligible compared to the demand. Therefore, it is fundamental to maintain the equilibrium between consumption and production, and to that end, we need load forecasting. Numerous patterns motivate the study of time-varying models, including: changes in people's habits, increasing renewable capacities, more recently the coronavirus crisis. This thesis aims to propose adaptive methods for time series forecasting. We focus on state-space models, where the environment (or context) is represented by a hidden state on which the demand depends. Thus, we try to estimate that state based on the observations at our disposal. Based on our estimate, we forecast the load. The first objective of the thesis is to enrich the link between optimization and state-space estimation. Indeed, we see our methods as second-order stochastic gradient descent algorithms, and we treat a particular case to detail that link. The second contribution concerns variance estimation in state-space models. Indeed, the variances are the parameters on which the models' dynamics crucially relies. The third part of the manuscript is the application of these methods to electricity load forecasting. Our methods build on existing forecasting methods like generalized additive models. The procedure allows to leverage advantages of both. On the one hand, statistical models learn complex relations to explanatory variables like temperature. On the other hand, state-space methods yield model adaptation

Повний текст джерелаIn a context of demographic growth in which natural resources are more and more limited, optimized management of water and power networks is required. Changes in electricity markets regulation in several countries have recently enabled effective integration of Demand Response mechanisms in power systems, making it possible to involve electricity consumers in the real-time balance of the power system. Through its flexible components (variable-speed pumps, tanks), drinking water systems, which are huge electricity consumers, are suitable candidates for energy-efficient Demand Response mechanisms. However, these systems are often managed independently of power system operation, for both economic and operational reasons. In this thesis, the objective is the evaluation of the economic and the ecological values related to the integration of drinking water systems flexibility into power system operation through french demand response mechanisms. An analysis of the architecture of french electricity markets is first conducted, allowing to target the most suitable demand response mechanisms considering water systems operating constraints. Some mathematical models to optimize water systems flexibility are then proposed and solved through original heuristics, integrating uncertainties about water demands, market prices and pumping stations availability. Numerical results, which are discussed using three real water systems in France, integrate the economic aspects inclunding risks, operational and ecological aspects. Significant reductions in water systems operating costs are estimated through the optimization of demand response power bids on the French spot power market during peak times. In parallel, uncertainties consideration secures the operation of water systems in real time, and makes it possible to manage economic risks related to the power grid balancing. In addition, significant savings in CO2 emissions, estimated to around 400 tons per day in France, can be achieved by reducing electricity production from fossil sources
