DISEGO

The digitization of the electrical distribution network, for example using an Energy Internet of Things (eIoT) platform and the establishment of active grid management based on this platform through smart grid microservices, represents a necessary and feasible step.

The DISEGO project brings together an interdisciplinary consortium of research and industry partners. They are pooling their respective expertise to develop a sustainable technology and put it into practice.

Project duration: 11/2022 to 03/2026

The electrification of the mobility and heating sectors and the sharp increase in EEG feed-in from photovoltaic systems pose a challenge for distribution network operators, as the electrical distribution networks are not designed for the expected load increases.

This is why intelligent grid automation is necessary to continue to ensure a high quality of supply in future scenarios, while minimizing grid expansion through optimal grid expansion strategies.

This requires grid status monitoring at the low and medium voltage levels, as well as the integration of controllable systems so that loads and feed-in can be used to benefit the grid when necessary.

DISEGO combines solutions for research objectives 1 to 3 in an energy IoT (Internet of Things) platform and connects them to existing systems in the real grid.

1. Minimally invasive grid state estimation
   Based on dynamic energy data from the distribution network, a minimally invasive and robust network state estimation is to be provided. Above all, this should be able to indicate equipment overloads of the lines and the transformer as well as voltage band violations.
2. Traceable evaluation of recommendations for action
   Based on the qualitatively labeled grid state estimation, traceable recommendations for action are to be created, which are visualized in a traceable manner for the system operator in the control room with regard to AI decision support. For this purpose, methods for the continuous improvement of system models of distributed energy systems are being developed.
3. Tamper-proof and wireless communication connection
   Approaches for radio-based communication are being developed so that individual modules and energy systems can communicate based on a tamper-proof long-range radio protocol.
