The European Commission’s DG ENER selected Artelys to analyse solutions for ensuring the frequency stability of the European electricity system in the future. This study analyses the role of inertia and its evolution in the context of asynchronous renewable energy deployment. This work establishes a shared understanding of inertia’s role in power system stability.
The literature review carried out by Artelys focuses on the challenges and risks associated with frequency stability in the electricity system, the definition of inertia, the specification of the physical quantities required to ensure this stability, the fundamentals determining inertia requirements and the definition of associated services. Artelys also analysed the foreseeable evolution of inertia requirements with the energy transition, as well as the existing inertia and fast reserve markets.
Artelys carried out this study with Tractebel ENGIE and Trinomics. Tractebel ENGIE conducted a technology review and a complementary assessment of inertia requirements. Trinomics analysed approaches to securing the supply of inertia and recovering the associated costs. A set of recommendations was formulated for DG ENER.
