Brief biography

I studied "Energie- und Prozesstechnik" (Energy and Process Engineering, BSc) and "Scientific Computing" (MSc) at the Technische Universität (TU) Berlin. Besides, I partly studied "Regenerative Energiesysteme" (MSc) at the TU Berlin and the Istanbul Teknik Üniversitesi. In 2014, I worked as a Technical Consultant in Renewable Energies and Microfinance at MicroEnergy International GmbH (MEI) in Armenia, India, Nepal, Pakistan and mostly in Bangladesh during the foundation of the MEI spin-off ME Solshare Ltd. where I was inspired for my Master thesis "Modeling and simulation of a droop controlled swarm type low voltage DC microgrid in a DAE framework". In November 2015, I started my doctoral dissertation "Modeling, control and simulation of swarm type DC microgrids", financed by a scholarship of the Berlin International Graduate School in Model and Simulation based Research (BIMoS). Since December 2017, I work in the DFG project "COnsistent COntrol of HYbrid PowEr systems" (Cocohype) in cooperation with the Potsdam Institute for Climate Impact Research PIK within the DFG Priority Programme 1984 "Hybrid and multimodal energy systems: System theoretical methods for the transformation and operation of complex networks".

Research topics/interests

Core topics

  • Swarm electrification in the global south
  • Structural (i.e., network topology) and control aspects in prosumer based DC grids in the global energy transition
  • Hierarchical control theory for hybrid (AC/DC) power systems
  • Methods for analysing hybrid (AC/DC) power systems

Interface topics

  • Sector coupling from a network perspective (electricity, gas, heat, mobility)
  • Water-energy-food nexus and climate resilience

Side topics

  • Open science, open source, open hardware
  • Change of knowledge transfer in the society - interaction of research, politics, economics and people

Open thesis topics

Please approach me if you are motivated and interested in my research topic and none of the following thesis topics exactly fits your interests. Find insights on swarm electrification here [1].

  • Petri nets for swarm grid control (producer/consumer switching) [BA]: Based on two previous theses, a control problem based on an existing Petri net model for solar DC swarm grids should be derived and solved. (Prerequisites: Discrete event systems lecture)
  • Overview on inputs (Stellgrößen) and outputs (Regelgrößen) for power grids (including different time and network scales, past/now/future) [BA]: This thesis is mainly a literature research topic. It can be combined with simulation examples. (Prerequisites: Electrical Engineering, Control Systems)
  • Non-linear power flow analysis for hybrid (AC/DC) power grids [MA]: In this thesis, non-linear power flow in pyPSA [2] should be extended to hybrid power grids. Therefore, the interconnection of AC and DC nodes must be revisited. Find the linear power flow for an AC/DC example here [3]. (Prerequisites: Electrical Engineering/Computer Science background)
  • pyPSA optimization of swarm grids [BA/MA]: In der Arbeit soll die Pythonbibliothek pyPSA [4] zur Leistungsflussberechnung auf Schwarmnetze (=über Gleichstrom (DC) vernetzte Prosumer) anwendbar gemacht werden. Dabei sind insbesondere die Prosumerknoten in pyPSA zu integrieren. Im Anschluss sollen beispielhaft Betriebsszenarien für Schwarmnetze simuliert werden. (Prerequisites: Basic python knowledge and motivation for programming)
  • DPSA.jl development and simulation [MA]: DYNAMICAL power system analysis tool; thesis in cooperation with PIK [5] and elena international [6]
