Integrated Energy Systems Laboratory

360 picture of the lab


In the face of climate change and resource scarcity, energy supply systems are on the verge of a major transformation which mainly includes: the introduction of new components and their integration into the existing infrastructures, new network configurations and reliable topologies, optimal design and novel operation and control schemes, and new incentives and business models. This revolution is affecting the current paradigm and demanding energy systems integration into Multi-Carrier Energy Hubs/Islands, while increasing the need for accommodating new platforms and devices. Advanced Power Electronics (PE) systems and interfaces, Energy Storage Systems (ESS) as well as Power-to-X (P2X) units are among those key players that help not only to enhance energy reliability and flexibility, but also to support higher penetration of Renewable Energy Sources (RES). This transformation is also accommodating active participation of end-users as responsive prosumers at different scales, which in turn help to reduce energy costs to all consumers and mitigate carbon footprints.

The INTEGRATED ENERGY SYSTEMS laboratory (IES-Lab) covers these promising and dynamic areas of research and development, and allow modeling and testing of different solutions and contributions in design, control and operation of IES through in-silico (e.g., different simulation platforms) and in-vitro (e.g., energy networks emulators and Real-Time Hardware-In-the-Loop) studies.



The IES-Lab facility currently operates around the advanced 12-core real time simulator that is fully compatible with the Matlab/SimPowerSystems and can be used for a broad range of applications. In particular, the simulator is able to:

  • Simulate in real time complex energy networks on paralleled CPU cores
  • FPGA-Based Power Converter Simulation Demonstration
  • Interface with power amplifiers for testing the influence of physical equipment (either power hardware or controller prototypes) on simulated infrastructure
  • Design rapid control prototypes

Hardware infrastructure includes voltage source converters (VSC) that can be run as single units or parallel connected, three-level neutral point diode clamped (NPC) converters, converter controllers, real time simulator and a Host PC. Converters are controlled through dSpace MicroLabBox, suitable for quick control algorithm testing and monitoring. Therefore, new control algorithms can be designed in MATLAB/Simulink and experimentally verified on this set-up.

Power hardware in the loop (PHIL) interface can be also stablished through interfacing the RT simulator OP 5600 and dSpace controller.
