Texte intégralThe 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

Texte intégralWe consider a power generation system comprising thermal units and pumped hydro storage plants, and introduce a model for its weekly cost-optimal operation. Due to the uncertainty of the load, the mathematical model represents a dynamic (multi-stage) stochastic program. The model involves a large number of mixed-integer (stochastic) decisions but its constraints are loosely coupled across operating power units. The coupling structure is used to design a stochastic Lagrangian relaxation method, which leads to a decomposition into stochastic single unit subproblems. The stochastic subproblems have deterministic counterparts, which makes it easy to develop algorithms for the stochastic problems. In this paper, a descent method for stochastic storage problems and an extension of dynamic programming towards stochastic programs are developed. The solution of the dual problem provides multipliers leading to preferred schedules (binary primal variables). The crossover heuristics evaluates the economic dispatch problems corresponding to a sequence of such preferred schedules. The combination of the restriction on dual preferred schedules (Lagrangian reduction) with the evaluation of a sequence (facet search) leads to an efficient method. The numerical results on realistic data of a German utility justify this approach.

Ta-Chia River, as one of the most important river in Taiwan, has plentiful water resources and steep topography, and thus is suitable for hydro power generation. Ta-Chia River hydro power plant is accounting for about a quarter of hydro unit installed capacity and 40% of hydro unit generating capacity in Taiwan. Besides, Ta-Chia River hydro power plant can remove peak load and start to modulate frequency, and emergency backup to stabilize the power system, playing an irreplaceable role in the taipower hydroelectric power system. However, the spatial and tempora distribution of rainfall is uneven in Taiwan and the short distances of hydro power plants along the Ta-Chia River area, it is an important issue to use the limited water resources efficiently. In this study, we build a model of unit commitment with cascade hydro power plants to simulate with thermal units, and solving it by mixed integer linear programming. The systems we simulate are thermal units, combined-cycle units, and hydro units in Ta-Chia river hydraulic power plant, recording the system load by every 15 minutes in 24 hours. Systems including hydro units are far more complicated than Systems including thermal units. Except the unit operation characteristics of thermal units, a coordination of cascaded hydro units dispatch should also consider the requied amount of water, the limit of reservoir water level…etc. Under the premise that system operation security is satisfied, proving water resources use as far as possible and reduce fuel costs of thermal units can achieve maximizing the benefits by thermal units. To meet the requirements of secure operation of the system, this thesis analyzes cases of water requirement of downsterm, reservoir water level, and reserve capacity of Ching-Shan hydro units. The simulation results are justify the cases that can be applied in reality. Keywords: Unit Commitment with Cascade Hydro Power Plants, Mixed Integer Linear Programming, Unit Operation Characteristics
