Brandenburg University of Technology, Cottbus-Senftenberg

BTU Cottbus-Senftenberg (BTU) is a young research-oriented technical university that combines university and technical college elements as a result of its background. Founded in 2013, BTU counts six faculties and about 8,000 students, making it the second largest university of Brandenburg.

1) Centre for Energy Technology, Chair of Energy Distribution and High Voltage Engineering (EVH)

BTU sees itself as a university that focuses on both fundamental and application-oriented research in four different fields, including energy efficiency and sustainability. The Chair of Energy Distribution and High Voltage Engineering is one of the cornerstone chairs of the Institute of Electrical and Thermal Energy Systems.

Short description of the project contribution

SMART Capital Region 2.0 – Optimised forecast and load control procedure in the smart grid

In the smart grid of the BTU’s central campus, the effects of a growing share of renewable producers, storage facilities and (controllable) loads in the electricity, heat, gas and electromobility sectors on the residual load and a load profile for ‘administration and other office uses’ are studied by 2019. To this end, the smart grid previously created at the BTU campus is used at a maximum load of 2.5 MW and developed further. In addition to the development of operating and optimisation strategies, a corresponding demonstrator will also be created at the BTU’s central campus within the scope of the WindNODE showcase. To enable the transfer of these results to other regions, a visualisation platform is being developed to show the geographical distribution of renewable generation and residual loads in north-eastern Germany over time.

2) Chair of Power Plant Technology (LS KWT)

At the Chair of Power Plant Technology, about 30 academic and technical employees are currently dealing with various subjects of the energy transformation in teaching and research. As its research and teaching is oriented towards the use of renewable energy, the focus of research activities lies on the development of:

  • Energy storage concepts in the context of conventional / flexible power plants and the use of surplus energy from photovoltaic installations and wind turbines.
  • Hybrid power plants for the decentralised flexible use as storage for renewable energy
  • Storage systems and their components using electrolysers as well as large-scale batteries in the hydrogen and storage research centre

Short description of the project contribution

BigBatt-innovative energy hub in the Lusatia area and development of a municipal energy management system (KEMS)

The research activities concern the scientific support of the BigBatt-innovative energy hub in the Lusatia area, the municipal energy management system in Cottbus and the corresponding visitor sites. Basically, the project is centred around measures that can be technically implemented within four years and are expected to have economic success in the future. To this end, flexibility has to be purposefully developed at all steps of the value chain.

Within the workstream for the Bigbatt-innovative energy hub in the Lusatia area, the main objective is the smart integration of the large-scale battery storage technology into the interconnected grid as well as in the deduction of concrete business models. That is why a specific deployment scenario is developed and implemented in the combined power plant together with the partners. A simulation model is further developed for use of the large-scale battery on the market for operating reserve and other optional uses. Furthermore, new recommended actions for large-scale batteries in new environments are developed.

In the KEMS workstream at Cottbus, the main objective is to analyse, develop and create a concept for viable and practicable energy clusters for the HKWG / Cottbus city model location. A technology and decision matrix is created to transfer the results, as a reference for municipal companies / utilities and as a basis for concrete investment decisions.
