On the integrated PV hosting capacity of MV and LV distribution networks
Open accessAbstract
The increasing adoption of residential-scale PV units raises concerns about the potential interactions with MV networks as large volumes of generation connected to one voltage level can limit the hosting capacity of the other. This work investigates such interactions from an integrated MV-LV perspective by analyzing the impacts that different PV penetrations in LV networks have on the hosting capacity of a real UK MV network. Realistic time-series load and PV profiles for a summer day are considered. It was found that the major limitation on the hosting capacity of MV-connected PV units is due to voltage issues of LV customers. In addition, results show that the largest MV-LV aggregated hosting capacity can be achieved by having most of the generation connected to LV rather than MV, highlighting the benefits of small-scale PV. These findings demonstrate the need to adopt more advanced, integrated MV-LV models in future distribution network studies.

The redundancy is typically higher in the medium voltage/high voltage grid in Switzerland, and there are more reserves (higher hosting capacity) compared to the low voltage grid.
“The redundancy is typically higher in the medium voltage/high voltage grid in Switzerland, and there are more reserves (higher hosting capacity) compared to the low voltage grid [83].”

In “MV-LV Integrated Hosting Capacity” (page unavailable), the paper reports that its UK case study accommodated almost nine times more PV generation when installations were predominantly connected to LV rather than MV—the opposite of the claimed hosting-capacity comparison. It studies a network in England, not Switzerland, and does not assess grid redundancy. (LLM, conf=0.87)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
