A Reliability-Constrained Scenario With a Decreasing Share of Nuclear for the French Power Sector in 2050 Mahmoud Mobir, Yacine Alimou, Valentin Mathieu, Vincent Mazauric, Nadia Maizi

Abstract

This contribution relies on a prospective study of the French power sector up to 2050 using the TIMES model, combined with a reliability operating condition. To consider transient short-term power grid conditions, a reliability indicator related to the reserves of kinetic energy was defined and endogenized in the model to guarantee power system reliability under the implementation of a high share of variable renewable energy sources (VRES). For a declining share of nuclear inducing a high share of VRES, the pace of investments, additional back-up and flexible options to guarantee the grid’s stability anytime were studied.
