Full textEnergy storage is a major challenge to ensure the safety of electrical networks and to promote the development of renewable energies. Veritable alternative to Pumped Storage Hydropower (PSH), the energy storage using compressed air (for CAES Compressed Air Energy Storage) is one of the most interesting technologies. In conventional systems currently in use, the compression energy is lost and the air is preheated during the expansion phase. This results in emission of CO2 and a low efficiency of about 50%. The AA-CAES (Advanced Adiabatic Compressed Air Energy Storage) aims to overcome these two drawbacks by storing the heat of compression in a thermal regenerator and restoring it before expansion in the turbine. Given the high thermal, mechanical and cyclic loading subject to the regenerator, the design of a lining capable of ensuring stability, insulation and sealing is a main issue of the system. This crucial point is the main axis around which this research is articulated. A laboratory testing campaign has been conducted to study the thermal, mechanical and hydraulic behavior of all materials involved in the underground regenerator excavated in a crystalline rock. For the humid air, whose thermodynamic behavior is not well studied within the range of the high foreseen temperatures and pressures, a new theoretical model was developed. In the same way, a thermo-hydro-mechanical model was developed for a deformable porous medium saturated with a compressible fluid. The implementation of this last model into a finite element numerical code was used to examine several lining configurations and to study the effect of coupling mechanisms on the temperature field and the mechanical stability. To validate the developments made and the proposed lining solutions, a prototype of a small scale regenerator combining temperature and pressure was built in the LITEN laboratory of CEA in Grenoble. The results of the conducted experiments and modeling revealed the importance of the convection phenomenon in the insulating bricks of the lining and the need to seal the system before thermal insulation

Full textAs part of the development of a compressed air energy storage system, the proposed study deals with the control and the energy optimization of a reverse multielectrical machines and multi-pumps system in order to maximize the efficiency. The pumping system is identified as the most influential element towards energy performances. A variable speed control structure is proposed and allows constraining the pump working in dynamic mode closed to the best efficiency points, called Best Efficiency Points. The control laws subject the electromechanical conversion to a cyclic and transient operation. A method for sizing the electrical machines by minimizing the losses of the {converter - PMSM } system over an operating cycle is proposed. The implementation of a simulation as well as an experimental test bench allows the study of the performance of the cyclic speed control of a conversion module. Finally, the study of the electrical interconnection of the modules between them is proposed for the development of the complete conversion platform. The purpose consists in smoothing the power fluctuations on the intermediary connection with a DC bus

Full textThe contribution of the renewable energy sources in the electricity generation mix is greatly increasing. Thereby, the integration of the energy storage technologies into the electrical grid is becoming crucial to reduce the drawbacks of the renewable energy sources. Then, the objective of this thesis is to evaluate the cost-effectiveness, to optimize and to study the transient behavior of a novel isobaric adiabatic compressed air energy storage (IA-CAES) system. This plant is characterized by the recovery of the compression heat and the storage of the compressed air under fixed pressure in hydro-pneumatic tanks. These allow improving the efficiency and the energy density of the storage system and avoiding the use of fossil fuel sources.Firstly, a steady state model is developed to perform energy and exergy analyses of the IA-CAES system. An exergoeconomic model is also carried out in order to optimize the cost-effectiveness of the storage system by using a genetic algorithm. So, an objective function, which includes the investment cost and the operating cost, is defined to be minimized. The system efficiency is 55.1% in the base case, it is improved to 56.6% after optimization with a decrease in the capital investment by 5.6%.Secondly, a dynamic model is developed to study the flexibility of the storage system and its ability to meet the electrical grid requirements (primary and secondary reserves) by evaluating the duration of the transient states. The results show that the storage system needs more than 2 min before being able to consume all the excess energy available on the electrical grid and more than 5 min before being able to produce all the energy required by the electrical grid. Suggestions are analyzed to improve the flexibility of the storage system such as the operation of the storage system in standby mode with low speeds. It allows reducing the energy losses by 68% during the storage mode and by 27% during the production mode compared to the standby mode in nominal speeds

Full textDue to the variability and intermittency of renewable energy such as solar technology, its large-scale integration into the micro-grid of energy production remains complicated because the large-scale photovoltaic power plants directly connected to the electricity grid may create instabilities. In addition, this variability of the solar resource does not allow the use of photovoltaics for the stand-alone system. Dealing with these issues, one of the solutions for a deployment of renewables such as photovoltaic is the set-up of energy storage inside the grid. However, the most common technique is based on the use of lithium-ion batteries, which remains not environmentally friendly during the recycling or during the destruction after their use. So, the Compressed Air Energy Storage system (CAES) appears as a solution to this disadvantage. In fact, my thesis aims to study the feasibility of this kind of energy storage technology using a small and medium photovoltaic power plant, and its instant operation to supply electricity to the buildings and the unconnected areas. In this thesis, we present the modeling, simulation, and optimization of a ten-kilowatt compressed air storage system designed to supply instantly a building with real loads. The model performed reflects the dynamic operation of the overall system consisting of the building, the photovoltaic field, the electrical grid, and the compressed air storage module. The optimization carried out allows the sizing of a compressed air storage system with a better efficiency (about 55%). The integration of a heat recovery unit equipped with electrical resistance and the adding of a variable speed compression module allow the building to reach the energy autonomy as a battery system for a standalone site
