Temperature dependent dynamic loadability control for transmission lines

open access: yes2011 International Conference on Advanced Power System Automation and Protection, 2011
Introducing Dynamic Thermal Line Rating (DTLR) algorithms into existing power systems protection and control allows for better utilization of already existing overhead transmission lines. DTLR application creates a possibility of increasing currents flowing through line conductors (over their normal values) and following on from this also increasing ...

Long-Term Voltage Stability Assessment of an Integrated Transmission Distribution System

open access: yes, 2017
Long-term voltage stability assessment (VSA) of independent transmission (T-VSA) and distribution (D-VSA)systems have been studied since long to estimate load margins. However, their impacts on each other have been neglected due to simplified assumptions

Loadability increase in radial transmission lines through reactive power injection

open access: yes2017 6th International Conference on Clean Electrical Power (ICCEP), 2017
This paper investigates the loadability increase that can be obtained in radial transmission lines by means of a synchronous condenser connected at the receiving end of the line. In this configuration, the reactive power reserve at the receiving node can be used (at least in the best part) to control the reactive power flow in the radial line. This way,

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

A Framework for Qualitative Analysis of Voltage Stability Indices (VSIs)

open access: yesIEEE Access
Voltage stability assessment (VSA) is invariably an essential step in the satisfactory operation of power system. For this, several Voltage Stability Indices (VSIs) based on 1) Existence of solution for voltage equations, 2) Maximum power transfer (MPT ...
