Modelling the thermal effect of solar radiation on the ampacity of a low voltage underground cable
(International Journal of Thermal Sciences, 2018-08)
Compared with other underground cables, low voltage cables are most intensely heated by the sun due to the low laying depth. Accordingly, the main purpose of this paper is to show how the heat of solar radiation affects ...
A transient thermal model for flat-plate photovoltaic systems and its experimental validation
(ELEKTRONIKA IR ELEKTROTECHNIKA, 2019-04)
This paper describes a transient thermal model that accurately predicts the temperature of the open-rack mounted photovoltaic (PV) modules under varying atmospheric conditions. The PV module temperature is predicted by ...

Increasing the ampacity of underground power cables by an application of photovoltaic pavements," The 6th International Conference on Renewable Electrical Power Sources
(The 6th International Conference on Renewable Electrical Power Sources "6th ICREPS", 2018-10)
This article shows that a significant increase in the ampacity of an underground cable line can be achieved, if a photovoltaic pavement in combination with a ventilation channel is applied along the entire length of the ...
A review on new methods for increasing the ampacity of underground power cables: Cool and photovoltaic pavements
(The 6th International Conference on Renewable Electrical Power Sources (6th ICREPS), Belgrade, Serbia, 2018-10)
The introduction of cool and photovoltaic pavements in underground power cable engineering
can contribute to reducing global warming and our dependency on fossil fuels. In this case, a cool or
photovoltaic pavement would ...
The effect of solar radiation on the ampacity of an underground cable with XLPE insulation
(The 4th Virtual International Conference on Science, Technology and Management in Energy (eNergetics 2018), 2018-10)
The main purpose of this paper is to quantify the thermal effect of solar radiation on the ampacity of a low voltage underground cable with cross-linked polyethylene (XLPE) insulation. The quantification was performed for ...
Optimal Placement and Sizing of Inverter-Based Distributed Generation Units and Shunt Capacitors in Distorted Distribution Systems Using a Hybrid Phasor Particle Swarm Optimization and Gravitational Search Algorithm
