ENSURE II - “Neue EnergieNetzStrUktuRen für die Energiewende”                                                                   

With the energy transition, the electrical power system's requirements are changing. For this reason, experts from science, industry, and civil society organizations are developing a systemic approach for future power supply systems. In order to achieve the Paris climate agreement, Germany wants to use mainly renewable energies until 2050. The shift toward a sustainable energy system leads to some complex challenges:

  • volatile feed-in,
  • new energy-transportation tasks,
  • sector coupling,
  • shut down of large power plants that ensure today’s system stability.

ENSURE is working on a future power supply system that is suitable for the new challenges. In addition, the path from today's to the future system is outlined.

Our contribution

The shift in power generation results in less controllable units in the transmission system and more controllable units in the distribution system. Therefore system operation must be adapted to the new conditions concerning ancillary services and system stability. In order to counteract the lack of control options in the transmission grid, one potential approach is to control DERs in clusters to provide ancillary services for the transmission grid or a higher voltage level in general.

For this reason, a distribution network control system, which enables the control of the power flow between two voltage levels, is developed. Through the control system, ancillary services can be provided from the distribution grid to the (sub-)transmission grid. For example, in the transmission system's emergency state, the power flow between the transmission and distribution grid could be adjusted to prevent a system-wide blackout. The control system uses Distributed Energy Resources (DERs) as actuators. This type of control system is defined as Cross-Voltage-Level Power Flow Control (CPFC).

Beyond pure simulative testing, the control concept will be investigated in the Smart Grid Technology Lab through power hardware-in-the-loop simulations.
