Aligning Use Cases for the Next Project Steps

In March 2026, the FLEXI project held its first series of use case workshops, bringing together use case providers and technical partners to build a shared understanding of the project’s four demonstrators and align them with the technical development of the FLEXI framework.

Objectives of the Workshop Series

These early-stage workshops were designed to:

• build a common understanding of each use case’s scope,
• consolidate the defined use case scenarios,
• align operational needs with technical development, and
• prepare the ground for agreed Key Performance Indicators (KPIs), defined data needs, and a structured pathway towards FLEXI’s Key Exploitable Results (KERs).

Siemens Workshop

The workshop focused on the microgrid business park use case, in which FLEXI will optimise the operation of electric vehicle (EV) chargers and stationary battery resources within a Siemens microgrid test bed. The discussion centred on how an AI-powered energy assistant could collect user and charge point operator constraints and translate them into machine-readable inputs for optimisation.

UBITECH Workshop

The UBITECH workshop addressed the use case of an AI-powered digital assistant for the clean energy transition, focusing on household demand forecasting enhanced by LLM-based interaction. The discussed scenarios included changes in occupancy, comfort preferences and appliance usage, clarifying incomplete input, trust and user feedback, and mapping user input to the digital twin.

CheckWatt Workshop

The session explored flexibility markets such as FCR, FFR, mFRR, DSO congestion services and behind-the-meter optimisation. A key topic was the optimisation of forecasting and dispatch, and the determination of which markets to participate in while respecting technical constraints such as battery state of charge (SOC), charging speed and regulatory requirements.

FEN Research Workshop

The FEN Research workshop focused on the use case of sector-coupled energy optimisation. The investigation is applied to a real case study based on the EWest and HyWest “Power on Demand” and “Power to Hydrogen” living laboratory of FEN Research GmbH developed within the REINFORCE EU-Project at the Green Energy Center Europe in Innsbruck.

The living lab incorporates photovoltaic (PV) systems, batteries, electric vehicles (EVs), heat pumps, smart metering, hydrogen systems and an energy community that connects two laboratories. One of the key challenges identified was the lack of coordinated control across the different subsystems.
