The term “digital twin” was already introduced by Michael Grieves in 2002 (see Grieves, 2016), and after about 20 years the concept has found its way into the energy sector on a broader base. The first applications of digital twins were for product lifecycle management within the aerospace industry at NASA. After this initial implementation of digi...
In the energy transition context, the use of steady-state time series is a promising approach to account for temporal interdependencies and flexibilities in modern distribution power system analysis, planning, and operation processes. This paper proposes a distributed backward–forward sweep power flow algorithm executed in a discrete-event, agent-b...
The ongoing transformation of the entire power system with a simultaneous convergence of different, previously separated energy sectors poses new challenges, especially for the energy transport infrastructure at the distribution level. Due to its important role for society as a whole, careful planning and stable, secure operation of this infrastruc...
The importance of battery electric vehicles (BEVs) for private mobility will increase significally within the coming years. This development will affect many areas of social life–from the mobility sector over spatial and urban planning to power systems. In particular, the associated demand for electric charging points, their connection to the distr...
In recent years, the distribution grid planning process has faced the big challenge to integrate renewable energy sources in its planning methodology while preserving a secure and stable provision of electricity. With the currently observable efforts to electrify human mobility all around the world, another new challenge arises for the planning and...
Academic studies and long-term planning demand for highly sophisticated simulation of distribution system’s usage considering operational actions and repercussions of market driven measures when applied on a large scale. This paper presents enhancements to the SIMONA tool enabling a large-scale distribution system simulation of a lifelike 50,000 no...
With the proliferation of electric vehicles, the electrical distribution grids are more prone to overloads. In this paper, we study an intelligent pricing and power control mechanism based on contextual bandits to provide incentives for distributing charging load and preventing network failure. The presented work combines the microscopic mobility s...

Die am ie3 entwickelte agentenbasierte Netzsimulation SIMONA wird kontinuierlich um neue Module und Funktionen erweitert und daneben auch in zwei Forschungsprojekten weiterentwickelt. Der vorliegende Beitrag stellt ausgewählte, größere Änderungen kurz dar und beschreibt darüber hinaus aktuelle Entwicklungen und Anwendungsfälle von SIMONA in den jew...
Volatile Einspeisung aus erneuerbaren Energien und der Ausbau der Elektromobilität stellen auf allen Ebenen wachsende Anforderungen an unsere Energienetze. Intelligente dezentrale Systeme und Anwendungen sollen diesen Herausforderungen begegnen und schaffen Raum für neue Anwendungen und Geschäftsmodelle.

Distribution systems operator (DSO's) are facing significant challenges in network planning due to the integration of distributed energy resources (DER), smart grid technologies, E-mobility, regulation and volatile market conditions. In the previous work, it was shown (a) how DSO's are able to optimise planning of network assets in the presence of...
DSO’s are facing significant challenges in network planning due to the integration of DER, Smart Grid technologies, E-Mobility, regulation and volatile market conditions. In previous work it was shown (A) how DSO’s are able to optimize planning of network assets in the presence of high uncertainty [1] and (B) how to describe the interdependencies b...
Due to politically defined goals to raise the share of renewable energy, the landscape of electricity production has changed in recent years. Normally, a decision to invest in new generation capacity by generation companies is often based on profit maximization criteria. Criteria considering the costs resulting from the required expansion or constr...
