  • Estimation of MILP dispatch parameters for different power plants
    Kategorie: Master Thesis
    Bearbeiter: Mario Beykirch
    Betreuer: Tim Janke
    In order to improve the quality of energy system simulation and optimization it is of crucial to work with realistic models for the individual production units. Using the entsoe data and the literature, this thesis' goal is to estimate the private dispatch parameters of thermic powerplants for an assumed dispatch model. Following a baysian approach, a posterior distribution for each parameter should be estimated.
  • How can a flexible office complex interact with future energy markets?
    Kategorie: Master Thesis
    Bearbeiter: Bastian Brindley
    Betreuer: Tim Janke
    Campus energy management systems jointly operate the multi-modal energy consumption and generation of a building complex, improving its overall cost position and its environmental impact. There is growing interest in such systems as increasing decentral, mostly renewable generation and more and more actively controllable loads such as e-car charging stations imply drastically improved opportunities. Additionally, future energy systems with a high faction of volatile renewable energy rely on the intelligent and flexible behavior of prosumers. The Master’s thesis will examine how such a system can interact with energy markets today and in the future. The Honda Campus in Offenbach will serve as an exemplary use case.
  • Modelling and Implementation of PV sources as VSI
    Kategorie: Bachelor Thesis
    Bearbeiter: Florian Schopp
    Betreuer: Johannes Börner
    Aim of the project is to implement the model a PV energy source as an VSI. Volatge source inverters are often used as the model to implement distributed energy reesources in micro grids. As a pre-study for larger and more general work a PV source willl be modelled and its feed into an electrical network studied.
  • Probabilistic electricity price forecasting and forecast evaluation
    Kategorie: Master Thesis
    Bearbeiter: Jens Haberzettl
    Betreuer: Tim Janke
    Wholesale spot market prices play the key role for the effective and efficient generation from renewable energy sources (RES), the thermal generation, and the flexible share of the demand. The rising share of generation from RES increases the volatility and uncertainty of future market prices and operators of generation units and flexibilities face an increasingly complex stochastic optimization problem with the price as a main source of uncertainty. Consequently, the paradigm in electricity price forecasting (EPF) shifted from point to probabilistic forecasting techniques in recent years. This thesis aims to critically review the current literature on probabilistic forecasting models and their evaluation metrics from a theoretical point of view. Furthermore, it should practically implement and test benchmark models for the probabilistic forecasting of the German day-ahead spot market prices as well as test new methods, e.g. from the machine learning literature.
  • Software defined Networking und virtual Controller Functions
    Kategorie: Master Thesis
    Bearbeiter: Anisch Bawer
    Betreuer: Johannes Börner
    The thesis aims to establish Virtual Controller Functions in a Software Defined Network.
    Characteristic for SDN is their seperation of the network data and controller plane. During the thesis a virtual SDN will be established and algorithm for a continous communication routing will be tested.
    Virtual Controller Functions will extend the idea of Virtual Network Functions from communication systems to caber physical systems. VNC fulfill tasks in a network in a distributed manner inside a virtual machine and are placed according to the network's needs. VCF will also function inside distributed virtual machines but also take into account control theoretic preferences and needs of the underlying physcal system.
