Cyber-physical energy systems modeling, test specification, and co-simulation based testing
The gradual deployment of intelligent and coordinated devices in the electrical power system needs careful investigation of the interactions between the various domains involved. Especially due to the coupling between ICT and power systems a holistic approach for testing and validating is required. Taking existing (quasi-) standardised smart grid system and test specification methods as a starting point, we are developing a holistic testing and validation approach that allows a very flexible way of assessing the system level aspects by various types of experiments (including virtual, real, and mixed lab settings). This paper describes the formal holistic test case specification method and applies it to a particular co-simulation experimental setup. The various building blocks of such a simulation (i.e., FMI, mosaik, domain-specific simulation federates) are covered in more detail. The presented method addresses most modeling and specification challenges in cyber-physical energy systems and is extensible for future additions such as uncertainty quantification
An Integrated Research Infrastructure for Validating Cyber-Physical Energy Systems
Renewables are key enablers in the plight to reduce greenhouse gas emissions
and cope with anthropogenic global warming. The intermittent nature and limited
storage capabilities of renewables culminate in new challenges that power
system operators have to deal with in order to regulate power quality and
ensure security of supply. At the same time, the increased availability of
advanced automation and communication technologies provides new opportunities
for the derivation of intelligent solutions to tackle the challenges. Previous
work has shown various new methods of operating highly interconnected power
grids, and their corresponding components, in a more effective way. As a
consequence of these developments, the traditional power system is being
transformed into a cyber-physical energy system, a smart grid. Previous and
ongoing research have tended to mainly focus on how specific aspects of smart
grids can be validated, but until there exists no integrated approach for the
analysis and evaluation of complex cyber-physical systems configurations. This
paper introduces integrated research infrastructure that provides methods and
tools for validating smart grid systems in a holistic, cyber-physical manner.
The corresponding concepts are currently being developed further in the

Smart grid co-simulation with MOSAIK and HLA: A comparison study
Evaluating new technological developments for energy systems is becoming more and more complex. The overall application environment is a continuously growing and interconnected cyber-physical system so that analytical assessment is practically impossible to realize. Consequently, new solutions must be evaluated in simulation studies. Due to the interdisciplinarity of the simulation scenarios, various heterogeneous tools must be connected. This approach is known as co-simulation. During the last years, different approaches have been developed or adapted for applications in energy systems. In this paper, two co-simulation approaches are compared that follow generic, versatile concepts. The tool mosaik, which has been explicitly developed for the purpose of co-simulation in complex energy systems, is compared to the High Level Architecture (HLA), which possesses a domain-independent scope but is often employed in the energy domain. The comparison is twofold, considering the toolsâ conceptual architectures as well as results from the simulation of representative test cases. It suggests that mosaik may be the better choice for entry-level, prototypical co-simulation while HLA is more suited for complex and extensive studies.Green Open Access added to TU Delft Institutional Repository âYou share, we take care!â â Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Intelligent Electrical Power Grid
