In order to satisfy the increasing demand for electricity and to meet this demand with renewable energies, the present electrical grid has to adapt. The EU has already initiated measures to standardize and support a European Smart Grid development to facilitate communication amongst experts of different domains. Hence, this requires a mutual harmonization of terminologies as well as tools to strengthen its bearing. This paper compares the DISCERN toolbox and the SGAM toolbox. Both address the issue of a standardized modeling solutions in the domain of Smart Grids. For both toolboxes the availability, requirements, and ease of use are examined and validated based on practical use case examples. Finally, the applicability for smart grid model driven development is discussed, open development issues indicated and suggestions for further improvements provided.
