Distribution grids are more and more penetrated by decentralized, flexible units. For this reason, aspects of active system operation become increasingly relevant there. The management of many active units on the lower voltage network levels is a challenge that requires improved data communication and multi-energy-system operation management. In this work, we propose a common data layer for different generic technology models that can be used in a standardized manner to depict energy consumption, generation, and conversion. The technology models allow to compute system operation points or dispatch schedules for different stakeholders related to distribution grids e.g., system operators.
