The safe integration of UAS into urban airspaces is one of the key challenges when establishing a UTM. A significant challenge to overcome is the detection and resolution of potential collisions. Such conflicts can occur for a variety of reasons and in different stages of the flight process, which makes them very complex to handle. A conflict manag...

The traffic volume of unmanned aircraft systems (UAS) is expected to grow significantly over the coming decade. The European U-space regulation draft defines in abstract terms how UAS traffic will be managed in future. Naturally, the draft omits compliance and implementation details, which are left to working groups at EASA and various standardizat...

As collaborative embedded systems operate autonomously in highly dynamic contexts, they must be able to handle uncertainties that can occur during operation. On the one hand, they must be able to handle uncertainties due to the imprecision of sensors and the behavior of data-driven components for perceiving and interpreting the context to enable de...

The energy transition necessitates a variety of control solutions to integrate renewables-based energy generation and unlock demand-side flexibility. To contribute to solving this challenge, the authors built a toolchain for developing smart grid control solutions. This toolchain consists of methodological, conceptual and technological components....

Collaborative embedded systems (CES) typically operate in highly dynamic contexts that cannot be completely predicted during design time. These systems are subject to a wide range of uncertainties occurring at runtime, which can be distinguished in aleatory or epistemic. While aleatory uncertainty refers to stochasticity that is present in natural...

In future cyber-physical systems, such as smart factories and energy grids, ontologies can serve as the enabler for semantically precise communication as well as for knowledge representation and reasoning. Multi-agent systems have shown to be a suitable software development paradigm for cyber-physical systems and may well profit from harnessing ont...

In this contribution, the experiences and results from the tests under real field conditions are described, which are concerned with grid automation systems in the research project Agent.HyGrid. Furthermore, the deployment of the grid automation system in a real-world distribution grid is discussed.

Fast changing markets require new manufacturing strategies to meet customers’ desires. Therefore, concepts of flexible and adaptable manufacturing systems are considered. This paper provides an overview of different approaches dealing with flexibility. A new concept based of the software product line engineering presents opportunities for easier re...

Collaborative embedded systems (CES) heavily rely on information models to understand the contextual situations they are exposed to. These information models serve different purposes. First, during development time it is necessary to model the context for eliciting and documenting the requirements that a CES is supposed to achieve. Second, informat...

This poster presents the basic concept of our third party control algorithm.

Active network management (ANM) is a promising approach to cope with the proliferation of distributed generation from renewables. The distribution system operator (DSO) can utilize its own assets in this regard, e.g. by installing remotely controllable on load tap changer transformers. Additionally, the DSO can incorporate distributed energy resour...

In recent years, several developments in the energy sector have been imposing major challenges on our energy supply infrastructure. Due to the liberalization of the energy markets that started in the 1990s, longstanding monopolies are being broken up and new actors enter the stage. An increasing awareness regarding the environmental impacts of foss...

Zusammenfassung Im Rahmen des vom BMWi geförderten Projekts Agent.HyGrid werden vereinheitlichte Energie-Agenten als Steuerungslösung für hybride Energiesysteme und -netze entwickelt und auf ihre Anwendbarkeit hin untersucht.

Im Forschungsprojekt Agent.HyGrid wird eine verteilte Automatisierungslösung für den Einsatz in hybriden Energiesystemen implementiert. Hiermit wird dem steigenden Anteil regenerativer Erzeugung sowie der Dezentralisierung der Energieversorgung Rechnung getragen, die die Praktikabilität zentral ausgelegter Architekturen mindert. Eines der Kerneleme...

The increasing share of electricity generation from renewables as well as the growing importance of distributed energy resources pose substantial challenges to the utili- ty industry that cannot be effectively tackled with central control schemes. The research project Agent.HyGrid is concerned with the implementation of a distribu- ted control solu...
