Abstract
The complex nature of cyber-physical energy systems (CPES) makes systematic testing of new technologies for these setups challenging. Co-simulation has been identified as an efficient and flexible test approach that allows consideration of interdisciplinary dynamic interactions. However, basic coupling of simulation models alone fails to account for many of the challenges of simulation-based multi-domain testing such as expert collaboration in test planning. This paper illustrates an extended CPES test environment based on the co-simulation framework mosaik. The environment contains capabilities for simulation planning, uncertainty quantification and the development of multi-agent systems. An application case involving virtual power plant control is used to demonstrate the platform’s features. Future extensibility of the highly modular test environment is outlined.
Highlights
A cyber-physical energy system (CPES) is an example of so-called systems of systems.Its dynamical behavior emerges from the interactions of various complex components and systems that themselves may display nonlinear dynamics
For setting up a co-simulation as in the application case described in Section 2.6, the typical first step is the definition of the objective
The results show that the technical VPP (TVPP) is able to optimize the schedules of its units such that the requirements calculated in the power system analysis are met
Summary
A cyber-physical energy system (CPES) is an example of so-called systems of systems.Its dynamical behavior emerges from the interactions of various complex components and systems that themselves may display nonlinear dynamics. A cyber-physical energy system (CPES) is an example of so-called systems of systems. CPES unite formerly separate domains from the physical energy systems, e.g., electric power grids, distributed energy resources (DER), or heat and gas networks, with the digital world of information and communication infrastructure (ICT), data privacy and cyber-security. Human behavior plays an important role, be it from an economic point of view with energy markets or through the social aspects of consumption behavior. Such human-driven systems are sometimes called transactive energy systems or H-CPES, but in the context of this paper, social and economic dynamics are included in the understanding of CPES. CPES should be considered in regard to their response to meteorological events or techno-environmental feedback
