Enjeux de flexibilité liés au développement des infrastructures réseaux pour l'intégration massive des énergies renouvelables variables dans le système électrique à l’horizon 2100

Abstract : The power system is facing a major shift with the large-scale development of variable renewable energy sources (VRES). This vertical and centralized architecture helped the system to be robust and reliable. However, VRES production is intermittent and less predictable. As a result, the system needs to add more flexibility with new options such as Demand Side Management, storage technologies and VREs curtailment. But renewable energies potentials are unevenly distributed in Europe and, with high shares of VREs, power flows exchanges will increase between specific regions. As a result, the existing transmission grid would face congestions and these flexibility options might not be sufficient to alleviate these bottlenecks. To analyse these impacts, the work carried in this thesis uses the long-term energy model POLES (Prospective Outlook on Long-term Energy Systems) coupled with the new European power sector module EUTGRID (EUropean – Transmission Grid Investment and Dispatch). It includes a detailed transmission grid and more realistic power flows with a DC-OPF. A grid investment mechanism is also incorporated to determine the grid investments based on nodal prices. This new coupling permits to get a dynamic evolution of the transmission grid. The role of the transmission grid is being assessed and compared with other flexibility options. The grid investments increase largely with important development of VRES while other flexibility options cannot completely replace them. Finally, an exploratory work is being carried with the introduction of generic distribution grids (urban, semi-urban and urban) in EUTGRID. The results show that the reinforcements are slightly delayed with a greater use of back-up technologies which increases the total emissions.
