TECNALIA presents its research developments within the ELEXIA project at EEM25 conference and CIRED 2025.

TECNALIA participated in the 21st International Conference on the European Energy Market (EEM), held in Lisbon, Portugal, from May 27th to 29th May 2025. Hosted by ISEL at Polytechnic University of Lisbon, the event gathered speakers from recognized energy institutions, industry, and academics to discuss about the most recent developments in energy markets. The presented research paper entitled “A Bidding Algorithm for the Joint Participation of Distributed Energy Resources in Day-Ahead Energy and MFRR Markets” co-authored by Nerea Ruiz, Joseba Jimeno, David González and Iñigo Muñoz from TECNALIA, is available here.

The paper presents the formulation of a multi-market optimization algorithm that will be implemented at the Portuguese Pilot located in the Port of Sines to demonstrate the fourth use case of the ELEXIA project related to the participation of flexibility resources in the provision of grid services to network operators. To this aim, actual data from the energy resources at the Port of Sines, including office buildings HVACs, electric vehicles, a photovoltaic generator, an industrial cooling warehouse and a Liquified Natural Gas (LNG) plant will be considered to define, in a simulated way, the combined optimal bidding strategy of an hypothetical aggregator in day-ahead energy and manual Frequency Restoration Reserve (mFRR) markets.

TECNALIA also participated recently in the 28th Conference and Exhibition on Electricity Distribution CIRED 2025, held in Geneva, Switzerland, from 16-19 June 2025. The presented paper, authored by David González, Nerea Ruiz, Joseba Jimeno and Maider Santos, is entitled “Blackbox MILP Optimization Model for Industrial Demand Side Flexibility Potential Assessment”  and will be available soon here.

This paper presents an innovative black-box model to simulate the flexibility of industrial loads and define their optimal operation set-points according to the electricity prices taking into account their technical and operational constraints based on a piecewise transfer function. This model will be also tested at the Portuguese pilot to model and optimize the flexibility behavior of the LNG plant.

Nowadays TECNALIA is involved in the integration of these tools at the Portuguese pilot to demonstrate their applicability.
