Amélioration de l’opérabilité des centrales électriques par l’intégration d’un système de stockage d’énergie

Abstract : The storage of electrical energy is now booming as it seems to be one of the necessary conditions to support the development of intermittent renewable energies in electrical networks. It competes, among other things, with historical sources of flexibility such as pumping stations or gas-fired power plants. The work of this thesis consists in the hybridization of two sources, namely the storage of energy in electrical form (lithium-ion battery) and a combined cycle (gas-steam cogeneration plant), in order to improve the stability of the networks and the operability of the plant. The main objectives are to specify the system specifications (functions, storage technology, pre-sizing), to create a configurable lithium-ion battery model based on the manufacturer's data and to define the control strategy for the hybrid. The pre-sizing methodology draws on both the similar work done by Gauthier Delille and the experience of General Electric, a manufacturer of combined cycles, to guide these systems towards suitable solutions. During the detailed dimensioning phase, the work led to the creation of a "system-oriented" lithium-ion battery model that can be implemented in GE's real-time software. This model, validated by tests in the GREEN laboratory, achieves a correct accuracy of about 95% (on cell voltage and energy). Finally, the energy management of this hybrid system is achieved by integrating a new controller in the power plant that provides instructions to the storage systems by processing both the internal data of the power plant and the data measured at the storage terminals. The choice was oriented towards simple commands (droop, PI, etc.) coupled with a fuzzy logic algorithm. This was configured using genetic optimization on data from an existing power plant. Despite several encouraging contacts with potential customers who showed interest in such a system, no prototype could be built.
