Battery-supported charging infrastructure for energy distribution grids

Status Ongoing
Problem description: The transition of the transport sector requires a substantial increase of charging infrastructures in the grid. As of today, the grid is already challenged by recurring and unpredicted demand peaks, influencing the grid quality. By adding a battery at the edge of the grid, we introduce flexibility, demand shaping, and novel methods for grid operations. The thesis will create a model addressing the use cases of car chargers, either in centralised location or in a rural settings. The main output is a model allowing for the assessment of input parameters such as grid capacity, charge demand profile, battery size and charge quality.
Methods and Tools: The tools and methods in this thesis are based on
  • A set of scenario, describing the challenges
  • A list of requirements being extracted from the scenarios
  • A description and evaluation of technologies and tools being candidates for solutions
  • A functional architecture/description of the envisaged system
  • An model addressing the core concepts
  • the applicability of the model for a specific use case
  • An evaluation of the solution, including a critical review of the decisions taken earlier
  • Conclusions
  • References
Time schedule The envisaged time schedule (for a short thesis/30 ECTS) is:
T0 0 starting month, T0+m denotes the month where the contribution to a certain chapter shall be finalized
T0+1 months: create an initial page describing the scenario, including the list of technologies which you think are necessary for the thesis
T0+2: Establish the table of content (TOC) of the envisaged thesis. Each section shall contain 3-10 keywords describing the content of that section - Provide a draft of section 2 (scenario) and 3 (technologies)
T0+3: Establish a draft on what to implement/architecture
T0+4: Set-up an implementation, testing and evaluation plan
T0+4: Evaluate your solution based on a set of parameters, keep in mind there is no such thing as a free lunch
T0+5: Deliver the thesis
Pre-Knowledge This thesis includes a reasonable amount of system analysis.

Red line

Your thesis should have a "red line", which is visible throughout the whole thesis. This means you should mention in the beginning of each chapter how the chapter contributes to the "goals of the thesis".

Use of scientific methods

A thesis follows a standard method:

  • describe the problem (problemstilling)
  • extract the challenges. These challenges should be measurable, e.g. method is too slow to be useful to voice handover.
  • Analyse technology with respect to challenges. Don't write & repeat "everything" from a certain technology, concentrate on those parts (e.g. protocols) which are of importance for your problem


  • Wikipedia is good to use to get an overview on what is happening. But there is not scientific verification of Wikipedia, thus you should use wikipedia only in the introduction of a chapter (if you use text from wikipedia). Use scientific literature for your thesis.
  • Scientific library is "at your hand", you can get there directly from UiO: [[How to get access to IEEE, Springer and other scientific literature -> Unik/UiOLibrary]]
  • I suggest that references to web pages, e.g. OASIS, W3C standards, are given in a footnote. Only if you find white papers or other .pdf documents on a web page then you refer to them in the reference section.

Evaluation of own work

Perform an evaluation of your own work. Revisit the challenges and discuss in how you fulfilled them. Provide alternative solution and discuss what should be done (or what could have been done).
