Electrical Impact of Photovoltaic Plant in Distributed Network
Open accessAbstract
This paper presents the problem of power penetration of photovoltaic (PV) systems in urban networks. After a qualitative problem description, two different environments for PV systems have been analyzed: rural and urban networks. Concerning the rural network, a single line has been simulated in order to evaluate the relation between the number of PV systems installed along the line and the maximum PV power installable. In the second part of this paper, possible problems due to power penetration have been examined concerning a clustered PV system that will be installed in the city of Torino (Italy) within the ambit of the EU project called POLYCITY.

Midday voltage rise, component overloading and voltage unbalance have been reported as major areas of concern as more PV systems are connected in distribution networks.
“In the literature [20][21][22], midday voltage rise, component overloading and voltage unbalance have been reported as the major areas of concern as more PV systems are connected in distribution networks.”
From Voltage Regulation in Rooftop PV-Rich Distribution Networks: A Review and Detailed Case Study (2026) · cites this paper as [20]
The Problem Description describes voltage rising when PV generation exceeds demand, for example at noon on a summer day. The Results also compare generated current with cable capacity, but do not report component overloading; the passages do not identify voltage unbalance as a concern. Thus the source supports the midday voltage-rise concern, not the full list. (LLM, conf=0.88)

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.
