mosaik A framework for modular simulation of active components in Smart Grids


In future Smart Grids, large numbers of heterogeneous components – distributed energy resources (DER), intelligent electronic devices (IED) and advanced power grid equipment such as FACTS – will have to interoperate in order to optimize their operation and provide a reliable and sustainable electricity supply. Next to the interaction of energy systems and ICT, interdependencies exist with market systems, consumer behavior and environmental influences. Simulation is an important tool for understanding the complex interactions between the interconnected elements and actors of Smart Grids. Furthermore, the simulation of Smart Grid scenarios allows for efficient and rapid evaluation of novel control strategies and technologies. This way, real-world experimentation can be systematically prepared, drastically reducing the costs and necessary effort for laboratory and field experiments.

Complex, interdisciplinary simulation requires the collaboration of various domain experts, which complicates the choice of a single modeling tool for the whole system. Furthermore, monolithic simulation setups typically display little flexibility and maintainability. An alternative approach is given by the coupling of various simulation tools in the context of a co-simulation. However, direct model coupling can lead to a high manual effort in the interface development, making the process rather error-prone. In addition, the developed approaches are usually problem-specific and can hardly be adapted for new application cases.

The mosaik project therefore aims to develop a framework that allows the semi-automatic creation of a Smart Grid co-simulation based on the reuse of existing, heterogeneous models. Mosaik supports common programming languages and simulation tools as well as relevant standards of the domain like Functional Mock-Up Interface (FMI) and OPC Unified Architecture. For flexible usage of the simulation a formal description of analyzed scenarios exists, allowing for comfortable co-modeling of test setups. Furthermore, mosaik serves as a virtual extension of the OFFIS SESA-Lab, bridging the gap between software and hardware-based testing.
This way, the mosaik co-simulation environment allows inexpensive and flexible testing of novel technologies and concepts for the Smart Grid, paving the way to their actual implementation in the field.
