Task lead by R&D Nester in OSMOSE Project delivers results on Stability, Flexibility and Reserve Exchange for the European Power System
As the Energy Transition progresses,
namely with the introduction of diverse flexibility sources, it is important to
ensure that the stability, efficiency and security of supply of the system is
kept. OSMOSE project ("Optimal System-Mix
of Flexibility Solutions for European Electricity") is looking into those
aspects.
In the context of the activities from task T1.4
- Innovative Flexibility Options in the Context of Planning, Operation and
Stability, led by R&D NESTER, the partners REN (PT) and ENSiEL (IT)
successfully delivered the internal deliverables associated with their
sub-tasks at the beginning of the current month of April.
These reports addresses two relevant topics from WP1 (Work Package), which tackles the long-term flexibility needs of the European power system, namely through the assessment of the impact of flexibility resources in multiple dimensions:
Sub-task 1.4.2 - "Cross-border reserve exchange for improved flexibility and efficiency", led by REN (Portuguese TSO), evaluates the long-term scenarios developed within WP1, with special focus on the Continental South West region (including Portugal, Spain and France), from the operational reserve needs perspective for this interconnected system. In this work, REN resorted to own tools.
Sub-task 1.4.3 - "Stability aspects", led by ENSiEL (Italian consortium of public universities), analysed the impact of high levels of renewable energy sources (RES) in the dynamic stability of South Italy power system. Additionally, assessed the contribution of these flexible resources, characterized by a power-electronics' based interface and/or low inertia (e.g. wind, solar, battery energy storage), to the dynamic stability of the system.
The two reports provide key takeaways from the analysis on the OSMOSE scenarios for 2030 and 2050 time horizons.
From the sensitivity analysis performed
in T1.4.2 for the Continental South-West region (PT, ES, FR), none of the
scenarios lead to any type of security of supply constraint. Nevertheless, in
the scenario Current Goals 2050 the operation conditions were more demanding
leading in some circumstances to reliability indexes (e.g. LOLE or EENS)
greater than zero.
On the other side, in the stability
analysis performed in T1.4.3 on part of the Italian power system, the
simulation results support that the Sicilian power system operates within the
normal frequency range when interconnection with continental Italy is
maintained. In the case this interconnection is lost, the Sicilian system
becomes less stable, requiring, in some scenarios, the contribution from wind
farms, BESS and DSR (e.g. synthetic inertia) in order to be able to maintain
the system's stability.

European Union's Horizon 2020 research and innovation programme under grant
agreement N°773406.
