InterSTORE partners recently showcased the project at IEEE PowerTech 2025 in Kiel, Germany. Elyas Rakhshani (HESS TEC) delivered a dedicated presentation covering:

System models: Architecture and parameterization of InterSTORE’s hybrid storage solution (fast-response + energy-dense) designed for stacked grid services.

PSCAD simulations: High-fidelity studies of grid-forming control under realistic operating scenarios, including low-inertia conditions and network disturbances.

Project results: Clear evidence that hybridisation enhances service delivery — fast frequency response, voltage support, and ride-through—while maintaining stability through grid-forming controls.

The InterSTORE project aims to advance hybrid energy storage and grid-forming control to deliver reliable, scalable services in renewable-rich power systems. IEEE PowerTech’s audience — researchers, technology vendors, operators, and policy makers — was perfectly aligned with the project’s mission. It provided an ideal platform to validate our work and benchmark results against the state of the art.

The InterSTORE focus areas matched several core themes of the conference:

  1. Real-time and high-fidelity simulation as the bridge from lab to field.
  2. Grid-forming converter systems for stability in inverter-dominated grids.
  3. Hybrid storage concepts that combine transient performance with energy shifting.

Key discussions at the conference centered on three main areas relevant to InterSTORE’s work. Control robustness drew strong interest, with participants engaging in detailed exchanges on the controller tuning methods and fault-handling strategies, and suggesting the development of comparative benchmarks across multiple grid-forming schemes. In hybrid sizing and economics, questions focused on identifying the optimal ratio between fast-response and energy-dense capacity to achieve both technical performance and cost-effectiveness. Regarding validation pathways, attendees encouraged expanding beyond PSCAD-based studies toward hardware-in-the-loop and real-time testing to reduce deployment risks and establish standardized test cases for wider industry adoption.

The event significantly increased InterSTORE’s visibility among academics and industry stakeholders, including experts in simulation and power electronics. Discussions reinforced the leadership in implementing and assessing services with grid-forming hybrid systems.

Special thanks to IEEE PES for organising the event and to all contributors from Kiel University (CAU), RWTH Aachen, KIT, and industry (including OPAL-RT and Siemens) whose insights enriched the project’s work.
