Germany decided to reorganize its energy supply system in a sustainable way by initiating the energy transition (Energiewende). One of its main targets is to be one of the most environmentally friendly and energy-conserving economies worldwide with competitive energy prices at the same time. This requires the support of all-embarrassing analytical systems, which take into account the technical, market and regulatory framework at once. Existing energy system analysis models often neglect or simplify the modeling of the electrical grid, which motivated the preliminary multidisciplinary work of the chairs of the FAU Erlangen-Nürnberg in the recent years.
A holistic system-oriented modeling approach for the electrical power supply system in Germany was initially developed with a focus on Bavaria. The model of the German electrical power supply system includes the transmission grid, conventional power plants and feed-in from renewables concerning the current market mechanisms in Germany. With the developed model it is possible to derive statements about grid and storage expansion or the development of CO2 emissions for the federal state Bavaria. The overall model includes sub-models for optimization (determination of cost-optimal expansion scenarios), for simulation (stochastic simulation of different scenarios with high temporal resolution and technical detail) and grid analysis (quasi-stationary AC load flow calculations) for checking the required grid planning criteria and stable system operation.
Within the research project KOSiNeK funded by the Federal Ministry for Economic Affairs and Energy (BMWi) we now extend the existing holistic system-oriented modeling approach for the German electric energy system to derive statements about the future development of the system within the European context. This includes both the evaluation of net expansion scenarios and the simulation and analysis of regulatory frameworks. In order to cope with the increasing complexity of the problem, new approaches from the fields of mathematics, computer sciences and net analysis are necessary, which includes aggregation and decomposition techniques, hierarchical multipoint model approaches as well as probabilistic methods to determine the probability of occurrence of certain conditions.
This leads to models of high complexity. To take this into account, the approaches from mathematics, computer science and grid analysis will also be coupled iteratively. This enables displaying technical and economic aspects with regard to the control of power plants in a very detailed manner as well as considering grid-regulations in order to guarantee a safe electrical power supply. In addition, it is possible to examine energy markets in an European context including their regulatory framework. The flexible and component-based model construction allows the influence of new market mechanisms such as dividing Germany into price zones or changing market conditions or funding mechanisms with a detailed, agent-based market model. For the integrated power grid analysis, the continental European transmission grid is integrated by network equivalents. A novel probabilistic approach will also be developed to evaluate the grid expansion scenarios.
The project KOSiNeK (project number 03ET4035) is funded by the 6th energy research program of the German Federal Ministry for Economic Affairs and Energy (BMWi).

Connected Mobility @ ZOLLHOF
Im Rahmen der Lehrveranstaltung Vernetzte Mobilität und autonomes Fahren haben die Studenten am 24.01.2019 an einem Workshop am Zollhof in Nürnberg teilgenommen. Nach einer regulären Vorlesung in den Räumlichkeiten mit Gründeratmosphäre konnten die Studenten in vier Gruppen eigene Ideen im Bereich der vernetzten Mobilität ausarbeiten. Dabei waren nicht nur technische Möglichkeiten relevant, sondern auch unternehmerische und interdisziplinäre Aspekte. In drei Themenbereichen (sicherheitskritische Anwendungen, Infotainment und routenbasierte Dienste) haben die Teilnehmer mit sehr viel Motivation interessante Ideen entwickeln können und lernten das Vorgehen nach dem Lean Canvas kennen. Ein aktuelles Startup aus dem Mobilitätsbereich (Thema: kostengünstige Parksensoren) hat die eigene Geschichte erzählt und aufgezeigt wie man aus dem studentischen Umfeld erfolgreich eine Idee zum Produkt entwickeln kann. Alle Teilnehmer hatten sehr viel Spass und haben angeregt für zukünftige Teilnehmer der Lehrveranstaltung das Format zu wiederholen.

Simulation-based evaluation of Quality of Service for 5G network mobility
The networking of vehicles with other road users or the infrastructure (Vehicle-to-Everything (V2X)) is one of the key technologies for autonomous driving and smart cities. The next generation of mobile communications (5G), which is going to be launched in 2020, takes into account use cases and criteria for V2X communication from the very beginning and is a key technology for autonomous driving. Foreseen autonomous driving functions need to be able to execute safety-critical applications and infotainment applications simultaneously. In the context of competition for network resources, a 5G network needs to consider these specific Quality of Service requirements and prefer safety applications at any time. The virtualization of mobile radio components (especially the core network) via network slicing is supposed to play a decisive role for the fulfillment of these QoS parameters in 5G. For the evaluation of various driving functions in the 5G context, BMW is cooperating with the Chair of Computer Networks and Communication Systems of the Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) to set up a 5G V2X simulation environment during the upcoming year. The aim is to evaluate the performance as well as the limits of a 5G network with respect to V2X use cases in different realistic traffic scenarios and to investigate them in detail.

Successful coorperation with thyssenkrupp
The Tech-Center Control Technology of the thyssenkrupp AG assigned Computer Science 7 to analyze the optimal dispatch of a cement plant by a combined optimization and simulation model. Mainly cost reduction potentials should be determined by optimizing the cement production considering the integration of storage within the whole production process. Furthermore, a redox-flow batterie and a wind powerplant were added to the cement plant in order to determine possible cost savings by reducing the grid power supply on the one hand and beeing able to offer frequency restoration reserve power on the other hand. The results showed that a significant decrease of electricity supply cost per produced ton cement is possible under certain conditions. For more detailed information please take a look at the paper presented at the Energieinformatik 2016 conference and the article in the technology magazine techforum published by thyssenkrupp AG.
