  • To test a Flexibility Service Mechanism (FSM) in a realistic environment, a geographically distributed power-hardware-in-the-loop (GD-PHIL) co-simulation is executed in the course of the HONOR project.

    The demonstrator consists of three modules:

    1. a simulated medium voltage grid running on an OPAL-RT real-time simulator at TUD in Dortmund (Germany)
    2. a physical low voltage grid with controllable load and generation assets in DTU’s SYSLAB in Riso (Denmark)
    3. a state-of-the-art control center environment at PSI in Dortmund (Germany)

    The physical and the simulated grids are virtually electrically coupled at a predefined grid node using a PHIL interface algorithm and set points can be sent to flexible assets in the physical low voltage grid from the control center monitoring both grids. Communication between the three modules is realized via WebSocket and the open-source tool VILLASnode.

    The setup enables the estimation of the available flexibility from the physical grid in the form of active and reactive power flow provisions at the grid coupling point within the limited grid restrictions. The target of the demonstrator is to monitor both grids in PSIcontrol and test an FSM developed by PSI which can mitigate congestion in the medium voltage grid through the control of flexible assets in the (simulated) medium and (physical) low voltage grid while considering grid restrictions.


    Experiments were finalized in February 2023 and results will be published soon.
