Investigation of Voltage Stability Indices to Identify Weakest Bus (TBC)
This paper proposes a new index to determine the static voltage stability of the load buses in a power network for certain operating conditions and hence identifies load buses which are close to voltage collapse. The proposed index is formulated from the quadratic equation derived from a twobus network and is computed using the apparent power and the line impedance. The proposed index shows how...
متن کاملA Review on On-line Voltage Stability Monitoring Indices and Methods Based on Local Phasor Measurements
On-line voltage stability monitoring based on the local phasor measurements is a very active branch of voltage stability assessment presently. It can be divided into local bus measurements based methods and local branch measurements based methods. The latter can be classified into three versions. They are voltage stability indices based on the feasible solution region of quadratic equation of r...
متن کاملComparative Study of Line Voltage Stability Indices for Voltage Collapse Forecasting in Power Transmission System
At present, the evaluation of voltage stability assessment experiences sizeable anxiety in the safe operation of power systems. This is due to the complications of a strain power system. With the snowballing of power demand by the consumers and also the restricted amount of power sources, therefore, the system has to perform at its maximum proficiency. Consequently, the noteworthy to discover t...
متن کاملOptimal Placement of Unified Power Flow Controllers to Improve Dynamic Voltage Stability Using Power System Variable Based Voltage Stability Indices
This study examines a new approach to selecting the locations of unified power flow controllers (UPFCs) in power system networks based on a dynamic analysis of voltage stability. Power system voltage stability indices (VSIs) including the line stability index (LQP), the voltage collapse proximity indicator (VCPI), and the line stability index (Lmn) are employed to identify the most suitable loc...
متن کاملAn Overview on Voltage Stability Indices as Indicators of Voltage Stability for Networks with Distributed Generations Penetration
The increase in Distributed Generation (DG) penetration in distribution network can be used as a means of addressing the increasing load demand without the upgrade of transmission lines. However, this increasing demand despite the supplementary supply from DG sources can cause the system to operate at its maximum capacity or at point of voltage collapse. It therefore, becomes necessary to deter...
