Abstract
In this paper, we present a comprehensive, multi-timescale approach to evaluate energy transition policies aiming at fully renewable generation in power systems of non-interconnected areas, typically islands or remote regions. The approach links three dynamic models: (i) a capacity expansion model, ETEM-SG, proposes an investment and generation plan for typical days, up to 2030; (ii) a simplified dispatch model is used to validate the generation plan for a full year of weather data and demand variations; and (iii) a static and dynamic analysis of the power system is used to assess the stability of the new power system for rapid events such as a sudden reduction of renewable generation. The proposed three-step approach generates a cost-effective long-term investment planning that ensures the balance between supply and demand at an hourly time step and the stability of the power system at a timescale of milliseconds. The presentation is based on a case study fully described in a report [1] made with ADEME, the French Agency for Ecological Transition, for the French island of La Réunion. It shows how a reliable 100% renewable power supply is achievable by 2030, in this area.

This comprised islands of La Réunion, Mayotte, Corse, Guadeloupe, Martinique, and French Guyana.
Robustness and reliability refer to (i) the ability to achieve balance between supply and demand for typical annual weather sequences and (ii) the design of a power system that remains stable in the event of unforeseen disturbances.

Residual capacities are the installed capacities at the beginning of the planning horizon. These installed capacities remain available for the remaining life of the technologies.
