Final report of PRODICON is published
FEN is excited to announce that the final report of PRODICON, Power system protection in presence of high shares of distributed converter-interfaced resources, research project funded by SFOE GRIDS Program, is now published!
The overarching purpose of the project is to devise a qualitative and quantitative framework to analyze the potential impacts of converter-interfaced resources on the protection layouts of distribution grids (MV & LV), especially when majority of large-scale conventional generation at high voltage (HV) and extra-high voltage (EHV) is de-activated during very high shares of distributed generation in MV and LV
grids. The specific objectives of this project are as follows:
- to identify the sufficiently accurate modelling type and platform (e.g., RMS) for converter-interfaced sources (e.g., solar PVs) in protection studies, especially in comparison with the calculations of industry standard, IEC60909-2016,
- to study the impacts of reduction in short-circuit current contributions from EHV and HV grids to faults in MV and LV grids,
- to assess the fault levels (i.e., short-circuit current, SCC, levels) in a given grid for various operating states (e.g., very high share of distributed generation),
- to formulate the impacts of different fault levels in selected scenarios, and
- to elaborate on potential mitigation measures.
