Texto completoThe Hydro Unit Commitment problem (HUC) is a difficult problem playing a major role in the scheduling of daily electricity production at EDF. In this thesis, we study different models and algorithms to solve the special case of the single-unit HUC problem (1-HUC). Studying this case is relevant for the following reasons. On the one hand, there are real world instances of the 1-HUC problem which cannot be solved efficiently by current approaches. On the other hand, it makes it possible to study individually two particular sources of difficulty. One stems from the presence of non-linearities, in particular the power which is a non-convex non-concave function of the flow and the reservoirs' volume. The other is due to the set of hydraulic constraints, specifically the volume minimum and maximum bounds, as well as target volumes for the reservoirs.In a first part, modeling alternatives for the non-linear 1-HUC, focusing on the power function, are proposed. The aim is to identify a model which can be solved efficiently, with a good trade-off between computational time and precision. The seven proposed modeling alternatives cover a large panel of modeling families. These models are compared on a set of instances with variations on five features that impact the solution. This comparative study enables us to identify three efficient types of model: a model with polynomial functions of degree 2, a model with a piecewise linear function, and a model using a finite set of flows. As the latter model is similar to the current model at EDF, in the following we present algorithms dedicated to it.In the second part, a polyhedral study is proposed to improve the solving approach of the 1-HUC problem. The idea is to focus on the combinatorial aspects, which means considering the relationship between the bounds on volumes and the discrete set of flows. For this purpose, we introduce a variant of the knapsack problem, with Symmetric weight and Chain Precedences (SCPKP). For the SCPKP, we characterize necessary facet-defining conditions, which are also proven to be sufficient in some cases. A two-phase branch-and-cut algorithm based on these conditions and on the symmetric aspect of the SCPKP is devised. The efficiency of this algorithm is then shown experimentally against state-of-the-art algorithms. The results of this polyhedral study of the SCPKP, as well as the proposed algorithms, are then extended to the 1-HUC problem.In the third part, an efficient solving technique based on a graph representation of the 1-HUC problem is proposed, taking into account of the hydraulic constraints. It appears that the 1-HUC problem is a special case of the Shortest Path Problem with Resource Windows (RWSPP). We propose two graph algorithms. The first one is an exact variant of the A* algorithm, using a dual bound dedicated to the 1-HUC problem. In comparison with two state-of-the-art approaches, we show numerically that this algorithm is more efficient for handling a specific case of 1-HUC. The aim of the second algorithm is to take into account a wider set of hydraulic constraints. The idea is based on the concept of bi-objective optimization, for which the second objective corresponds to a relaxation of the volume. The advantage compared to a classical bi-objective optimization is that it is possible to use the minimum and maximum bounds on the volume to reduce the search space and to guide the enumeration of solutions. We show numerically, on a large set of real instances, that this algorithm outperforms three state-of-the-art approaches. Although this algorithm was designed to solve the 1-HUC problem, it is defined in a generic way for any RWSPP with a single resource

Texto completoThe green bell pepper Hydroperoxide lyase enzyme expressed by the yeast Yarrowia lipolytica allows the hydroperoxide fatty acids transformation to aldehydes and alcohols. In this word, the purification and characterization of enzyme were realized: the participation of radicals during the catalysis of hydroperoxide lyase was founded and it has been observed that the radical species might be an alkyl or alkoxyl radical linked to the enzyme, which affected the active site of the enzyme losing his activity. The enzymatic activity enhanced significantly (42%) at low oxido-reduction potential. The secondary structure of enzyme is composed by 13% α-helix and 29% β-sheet. Moreover the loss of α-helix decreased the activity enzymatic. A factorial plan was applied to determine the factors influent on the production of hexanal: fatty acids hydroperoxides (100 mM) and dithiothreitol (100 mM)

Texto completoThis work relates the thermal optimization of an electrical machine. The lumped method is used to simulate the temperature field. This model solves the heat equation in three dimensions, in cylindrical coordinates and in transient or steady state. We consider two transport mechanisms: conduction and convection. The evaluation of this model is performed by means of 13 design variables that correspond to the main flow rates of the equipment. We analyse the machine cooling performance by varying these 13 flow rates. Before starting the study of such a complicated geometry, we picked a simpler case in order to better understand the variety of the available optimization tools. The experience obtained in the simpler case is applyed in the resolution of the thermal optimization problem of the electrical machine. This machine is evaluated from the thermal point of view by combining two criteria : the maximum and the mean temperature. Constraints are used to keep the problem consistent. We solved the problem using the gradient based methods (Active-set and Interior-Point) and the Genetic Algorithms

Texto completoThis thesis aims at presenting an optimal management and sizing of an Energy Storage System (ESS) paired up with Intermittent Renewable Energy Sources (IReN). Firstly, wedeveloped a technico-economic model of the system which is associated with three typical scenarios of utility grid power supply: hourly smoothing based on a one-day-ahead forecast (S1), guaranteed power supply (S2) and combined scenarios (S3). This model takes the form of a large-scale non-linear optimization program. Secondly, four heuristic strategies are assessed and lead to an optimized management of the power output with storage according to the reliability, productivity, efficiency and profitability criteria. This ESS optimized management is called “Adaptive Storage Operation” (ASO). When compared to a mixed integer linear program (MILP), this optimized operation that is practicable under operational conditions gives rapidly near-optimal results. Finally, we use the ASO in ESS optimal sizing for each renewable energy: wind, wave and solar (PV). We determine the minimal sizing that complies with each scenario, by inferring the failure rate, the viable feed-in tariff of the energy, and the corresponding compliant, lost or missing energies. We also perform sensitivity analysis which highlights the importance of the ESS efficiency and of the forecasting accuracy and the strong influence of the hybridization of renewables on ESS technico-economic sizing
