R&D NESTER PUBLISHES RESULTS ON THE TOPICS OF ENERGY DATA SPACES, ELECTRIC VEHICLES AND AGREGATED FLEXIBILITY
Last May, R&D Nester was represented in the 21st edition of the International Conference on the European Energy Market - EEM25, that was held in Lisbon, Portugal.
For the last 20 years,
the EEM Conference has been bringing together experts from academia, industry
and policy makers, to discuss cutting edge topics in energy markets. These
include approaches and solutions related to energy modelling, market design, regulatory
policies, climate change, technological developments, among other. In addition
to the core areas, the recent editions have given more emphasis on energy
storage, renewable and synthetic fuels, and energy citizenship.
R&D Nester was involved has a partner in this year edition:

The EEM25
three-day program included plenary sessions with keynote speakers from
recognized energy institutions, industry, and prominent academics, as well as
scientific sessions that cover a wide variety of energy markets related topics.
R&D Nester presented four papers on the topics of Energy Data Spaces, Vehicle-to-Grid and Aggregated Flexibility:
Paper produced in the scope of
ENERSHARE project: "Comprehensive Governance Models for Energy
Data Spaces: A Path to Secure and Interoperable Data Sharing in Europe"
The paper
introduces a systematic approach specifically designed for the energy sector to
address governance challenges in Energy Data Spaces. Based on an in-depth
analysis of questionnaires from pilot projects involving regulated and
non-regulated entities, it identifies key practices, needs, and difficulties in
real-world data sharing. The resulting Governance Models aim to ensure clear responsibilities,
compliance with EU regulations, and seamless interoperability across energy
data exchange frameworks.

Paper produced in the scope of
V2Grid project: "Study on the impact of electric vehicles'
charging in the national load profile: an analysis on Portuguese power system"
The paper analyzes
the impact of electric vehicle (EV) charging on Portugal's national electricity
grid, using real-world data to model residential, workplace, and public
charging behaviors under various adoption scenarios. It concludes that without
smart charging strategies and infrastructure upgrades, especially in high EV
penetration scenarios, EV adoption could significantly increase peak loads and
stress the grid, while technologies like Smart Charging and Vehicle-to-Grid
(V2G) offer promising mitigation solutions.


Paper produced in the scope of
V2Grid project: "Framework to estimate the charging
flexibility of EV fleets"
This paper
presents a data-driven framework to estimate the charging flexibility of
electric vehicle (EV) fleets by clustering real-world charging behaviors into
distinct user profiles based on multiple variables, including power usage,
session duration, and idle time. The analysis reveals that EV users with long
idle times, particularly in residential and fleet configurations, offer the
greatest potential for demand-side management and smart charging strategies,
enabling improved grid performance and renewable energy integration.

Paper produced in the scope of
Next Generation Storage project: "Assessing the Impact of Grid
Constraints on Aggregated Flexibility for Energy Market Participation"
This paper
presents a scenario-based co-simulation that quantifies how low-voltage grid
constraints reshape the flexibility an energy community can realistically bid
into electricity markets. It couples a causal-inference elasticity model
producing prosumer flexibility envelopes with two sequential PSSE power-flow
runs that estimates feeder losses to a community battery enforcing thermal and
voltage limits. Results show that technical constraints shave 5 - 15 % of
theoretical flexibility on calm hours and up to 50 % during evening peaks,
occasionally even enlarging flex when reverse-power voltage rise is mitigated.
The workflow offers DSOs and aggregators a repeatable way to size market bids
that are both economically attractive and grid-feasible.

R&D Nester was also represented in
the Plenary Session 7 that took place on the 3rd day of the event,
with the title: "Transmission and Distribution Grids: Key Enablers for the
Energy Transition".
Nuno Souza e Silva,
Managing Director of R&D Nester, participated in this panel
together with other speakers from REN, Siemens and IST.
