The power grid in Germany is facing major challenges. On the one hand, increasingly more decentralised electricity generators are feeding power into the low- and medium-voltage grids. On the other hand, the transport of energy over long distances is unavoidable in order to transport, for example, energy generated offshore to the load centres. Within this context, the joint KonVeTrO project is investigating how the energy supply system must be expanded in order to meet these challenges.

A special feature here is that while many optimisation approaches only deal with optimising an individual grid level or control zone, the KonVeTrO researchers are working on a planning method that considers the transmission, distribution and overlay grids at the same time. This is known in this context as vertically integrated, multilevel grid planning. It is intended to enable the improved division between the distribution, transmission and overlay grids. To achieve this, the researchers are transferring scientific methods and instruments from transportation logistics to the supply of electrical energy and are developing them further. By taking this approach, the team led by lead scientists Professor Rehtanz and Professor Alex Vastag would like to demonstrate the potential for integrating transport logistic planning concepts in the traditional planning of electrical power grids.

Basic information

How is our power grid structured? What sort of networks are there? What do security and quality of supply mean?


What do direct and alternating current mean? How do they differ and what are the advantages and disadvantages?


Virtual power plants, active distribution grids, smart meters and adaptive protection systems – here you can find information about the most important aspects of smart grids.


The energy generated in a grid must always be equal to the energy consumed. The ancillary services are tasked with ensuring this.
