The concept of cellular energy systems of the German Association for Electrical, Electronic & Information Technologies (VDE) proposes sector coupled energy networks for energy transition based on cellular structures. Its decentralized control approach radically differs from that of existing networks. Deeply integrated information and communications technologies (ICT) open opportunities for increased resilience and optimizations. The exploration of this concept requires a comprehensive simulation tool. In this paper, we investigate simulation techniques for cellular energy systems and present a concept based on co-simulation. We combine simulation tools developed for different domains. A classical tool for studying physical aspects of energy systems (Modelica, TransiEnt library) is fused with a state-of-the-art communication networks simulator (OMNeT++) via the standardized functional mock-up interface (FMI). New components, such as cell managers, aggregators, and markets, are integrated via remote procedure calls. A special feature of our concept is that the communication simulator coordinates the co-simulation as a master and integrates other components via a proxy concept. Model consistency across different domains is achieved by a common description of the energy system. Evaluation proves the feasibility of the concept and shows simulation speeds about 20 times faster than real time for a cell with 111 households.

The intermittent energy supply from distributed resources and the coupling of different energy and application sectors play an important role for future energy systems. Novel operational concepts require the use of widespread and reliable Information and Communication Technology (ICT). This paper presents the approach of a research project that focuses on the development of an innovative operational concept for a Smart Integrated Energy System (SIES), which consists of a physical architecture, ICT and energy management strategies. The cellular approach provides the architecture of the physical system in combination with Transactive Control (TC) as the system’s energy management framework. Independent dynamic models for each component, the physical and digital system, operational management and market are suggested and combined in a newly introduced co-simulation platform to create a holistic model of the integrated energy system. To verify the effectiveness of the operational concept, energy system scenarios are derived and evaluation criteria are suggested which can be employed to evaluate the future system operations., I3 programme of the TUHH and the Hamburg Ministry for Science, Research, Equality and Districts (BWFGB), Hamburg, Behörde für Wissenschaft, Forschung, Gleichstellung und Bezirke

Doctor of Missiology (DMiss), This dissertation explores the use of a conflict model to interpret Acts as seen in Luke’s consistent use of a “nothing can hinder it” motif. Part 1 deals with barriers preventing the advance of the gospel and identifies five corporate and four personal barriers that need to be overcome. Part 2 deals with numerous breakthrough categories, the first encompassing what might be called the Trinitarian nature of breakthroughs by highlighting God’s sovereignty through things He does, Jesus fulfills and the Spirit empowers. The second set of breakthrough categories is set within the mystery of human responsibility. This section lists five aspects of communicating the Word and another five demonstrating the Works that are done to demonstrate and validate the reality of the Word. After each barrier and breakthrough numerous personal and collective behaviors are listed that flesh out breakthrough dynamics, even though these applications only serve to illustrate the dynamics and are not intended to be repeatable patterns for all time. Luke’s readers are left to contextualize the Jesus culture in new situations. Parts 1 and 2 are summed up by an at-a-glance table in Appendix A that lists barriers and breakthroughs as they are narrated by Luke in Acts. On this foundation the work turns to the present age and analyzes five Vineyard churches to see if Luke’s breakthrough dynamics apply. The data will show that there are enough similarities to conclude that those churches that attempt to build cultures that emulate the breakthrough dynamics in Acts make forward progress through suffering. Having shown that Luke was intentional about using a conflict model as a principle lens through which to interpret Luke-Acts, this then legitimizes further study into what might be called “conflict criticism.” Assuming that the bigger story of the cosmic war between light and dark is always sub textual, interpreters should make the exploration of this conflict a part of their hermeneutical toolkit

Exploiting information transmission latency between stock exchanges in Frankfurt and London, and speed-inducing technological upgrades, we show that when cross-market latency arbitrage opportunities are linked to the arrival of information, high-frequency traders' (HFTs’) activities impair liquidity and enhance price discovery by facilitating the incorporation of public information into prices. Conversely, when cross-market latency arbitrage opportunities are driven by liquidity shocks, HFTs improve liquidity and reduce trading costs, thus incentivizing information acquisition and trading with private information. These findings underscore the complex nature of the association between trading speed and market quality and reconcile mixed evidence in the extant literature.
