Blog 6 - TransCampus academy-industry workshop in Dresden

Grazia, 27 November 2023

The project 'Modelling Distribution Systems for Transmission system harmonic studies' is supported by the TransCampus framework, a collaboration between Technische Universität Dresden and King's College London. 

The second workshop of this project took place in Dresden on November 8 and 9, 2023. The title of the workshop was: 'Challenges of harmonic studies in modern transmission systems'. The workshop was attended by approximately 50 participants, with 1/3 from academia and 2/3 from industry. (The first workshop took place in London on 30 May 2023). 

The workshop was organised in five sessions: a welcome session, two sessions with invited speakers, and two sessions with project updates. 

Professor Jan Meyer welcomes the guests at the workshop

The workshop was opened by Professor Meyer who welcome the guest and introduced the project and the context, followed by Dr Maike Haber who provided an overview of the TransCampus framework. Dr Ana Maria Blanco then provided further details on the workshop schedule, as well as technical visits and social events. 

Modern power systems include a growing number of power-electronics based devices, such as renewable energy sources. These devices are typically installed at the distribution system level (medium to low voltage). Nevertheless, they impact harmonic studies at the transmission system. Therefore, accurate computer models of these devices are required to fully evaluate their impact on the transmission system. The development, validation and implementation of such models is an urgent topic, and the workshop aimed at addressing some of these important questions. 

The invited talks presented various international research, standardisation and industrial activities with the aim to provide the state-of-the-art on distribution system models, and model validation. These project showed the importance to take uncertainty into account, in particular due to varying operating conditions, and parameter uncertainty. 

The project updates covered modelling aspects, measurements and equipment design using sample model networks for the UK and for Germany. These updated showed potential approaches that may help with future studies, but also identified further research needs. 

The closing discussion aimed at further exploring some of the main trends identified during the workshop, specifically: how to model uncertainty, the contribution of measurements, definition of emission limits, and the frequency range of interest for distribution system models and harmonic studies. 

The two-days workshop was also rich in other activities, including a visit to the TUD IEEH (Institute of Electrical Power Systems and High voltage engineering), a guided tour of Dresden city center,  and a social dinner. 

At the end of the workshop, many guests remained to further discuss and network. Overall, the workshop was a success and it allowed identifying future areas of research and collaboration for these important topics.
