In this paper, the basic concepts of dynamic thermal ratings of overhead transmission conductors are discussed. The sensitivity of these ratings with ambient conditions is evaluated. Innovative concepts in the measurement of overhead sag are given and correlated with dynamic rating of overhead transmission conductors. Dynamic transmission line thermal ratings take on increased importance in the...

With an increased focus on renewable power generation, dynamic thermal ratings of various equipment are being investigated to connect the new intermittent generation grid without needing replace existing infrastructure. Previous research is mainly focused a rating for overhead lines. End-of-line also restricted by limit. This paper combines model lines with transformer model, investigate impact...

The increased integrations of intermittent renewable energy sources into power systems cause more grid congestions and therefore system operators need advanced control to relieve this pressure. dynamic thermal rating (DTR) is able increase the constraint subsequently maximum loading existing lines. This achieved through real-time considerations weather data it usually much higher than tradition...

The aim of this paper is to present a novel phasor measurement unit (PMU) data-based cable temperature monitoring method with an intended application towards facilitating dynamic line rating. First part the presents estimate and track 3-phase segment. benefit that no additional sensors are required be placed along cable. based on algorithm which gives accurate resistance estimates for segments ...

Nowadays, optimal integration and utilization of renewable energy sources (RES) are of the most challenging issues in power systems. The wind and solar generation units' maximum production may or may not occur at peak consumption times resulting in non-optimal utilization of these resources. As a solution to this problem, energy storage systems (ESS) are embedded in networks. However, the power...

In this article, the dynamic thermal rating assessment method of oil-immersed power transformer with multiple operating conditions is proposed, considering constraints hot spot temperature (HST), top oil temperature, losses life and maximum allowable current on-load tap changer (OLTC) or bushing, which can determine load curves under different give most sensitive to limit capacity. To improve a...
