A framework for modular simulation of active components in Smart Grids

Motivation

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. Simulation is an important tool for understanding the complex interactions between the interconnected elements of Smart Grids and the evaluation of efficient coordination and control strategies.  In  addition  to real-world  experimentation and theoretical analysis, simulation offers the opportunity to study  the  behavior  of  future  power  systems  under  varying conditions and in numerous scenarios.

Current simulation approaches in the Smart Grid domain, however, are either implemented using a single, monolithic tool or based on a proprietary, manually implemented integration of different simulation tools/models. While the former only offer limited support for the integration (and thus reuse) of existing, well-known and validated models, the latter approach is tailored for specific scenarios and an adaption to different scenarios and new models is cumbersome and error prone.

The mosaik project therefore aims to develop a framework that allows the automatic creation of a Smart Grid simulation based on the reuse of existing, heterogeneous models. Mosaik therefore relies on a formal description of the models’ semantics and the scenario that is to be simulated. The mosaik simulation engine then evaluates these formal descriptions and composes the overall Smart Grid simulation. The scope of mosaik is the composition of models of physical devices such as consumers and producers of any kind as well as the components of the power grid. Mosaik therefore aims to offer energy standard compliant interfaces, e.g. based on IEC 61968/61970, IEC 61850 as well as OPC Unified Architecture, so that ICT components can easily be integrated and tested. This way, mosaik offers a fast and inexpensive possibility for testing and evaluating ICT based Smart Grid coordination mechanisms and making them ready for deployment in a real world environment.
