By integrating a high share of distributed generation units, microgrids can accelerate the shift to a more sustainable power grid.This transition is however not free from challenges.The variability and uncertainty of the renewable energy sources as well as the absence of large-scale dispatchable storage systems pose challenges for the integration and operation of this new type of power grid.Model-based engineering can provide valuable tools to develop design and control strategies that do not jeopardize the stability and reliability of the power supply.This paper presents elements of a Modelica-based workflow for the design and operation of microgrids.The framework allows for a multi-fidelity modeling approach and is therefore suitable for solving a large variety of engineering problems, from early component design to the verification of component and control design using detailed models.This paper illustrates the flexibility of the framework with respect to the user interface, the models and the analyses.
