To quantify the impact on reliability of supply of self-healing functionality (flexible grid topology) and flexibility resources and the interplay between these two means to manage the reliability of supply.
Work performed
A common case on security of electricity supply was defined with inputs from all CINELDI WPs and partners.
Reliability of supply in the CINELDI MV reference system was analysed using the open-source RelDist.jl code, calculating expected energy not supply, expected interruption costs, etc.
Significant results
Self-healing functionality is shown to significantly improve reliability of supply.
It is important to consider that backup feeders do not provide infinite grid reserve capacity.
The availability of reserves in flexible grid topology influence the benefits of flexibility resources to manage reliability of supply, and vice versa.
Impact for distribution system innovation
The case study has demonstrated the potential of new measures to manage reliability of supply. It also identified new research questions and knowledge gaps.
