The energy research centre NEXT ENERGY is an independent, non-profit research institute whose purpose is to play an active role in shaping the technological changes that are paving the way towards more climate-friendly, economically viable and reliable energy provision. As an independent affiliate institute of the University of Oldenburg, NEXT ENERGY employs around 120 members of staff.

In the System Modelling and Analysis R&D Group in our division Energy System Analysis, we develop and investigate models in order to be able to systematically describe and solve the resulting challenges facing our electricity supply system.

We are now offering research activities which are qualified for the preparation of a

Master Thesis:
“Comparison and validation of methods to reduce spatial resolution of power grid topologies”

Power flow simulations are constantly becoming more complex due to their high temporal and spatial resolution and representation details. However, limited computation capacities impede simulations of such large power systems. In this context, approaches to reduce the complexity of grid topologies while ensuring a good quality of the results are becoming important. Different methods to reduce the spatial resolution of power grids exist. The task of this master thesis is to implement and compare such approaches. A first part will be dedicated to the derivation of a comprehensive overview and comparison of different network complexity reduction techniques. A second part consists in defining representative parameters to evaluate the different techniques. The result should be a validated assessment of the implications for power flow simulations.

You should have completed, or be about to complete, your master course studies with all the pre-requisites for carrying out your project. Knowledge in the use of the programming languages Python and SQL is required; knowledge of electricity networks and their tools is desirable, but not essential. A good command of English is necessary.

As an extramural research institute, NEXT ENERGY does not award any academic degrees. The relevant regulations of your university with regard to externally completed projects must therefore be borne in mind. We will be happy to support you in discussions with your university. The advertised project shall begin in July or August 2017. If you are looking for an exciting, varied and practically-oriented task in an innovative subject area, please send your application, quoting the reference number ESA-2017-02, as a PDF-file by e-mail before 30th June 2017 to:
