Power system voltage collapse prediction using a new line stability index (NLSI-1): A case study of the 330-kV nigerian national grid [PDF]
, 2019 The cumulative number of historical and recent power system outages substantiates the fact that further studies are necessary for an improved solution to the issue of voltage instability on the grid and the subsequent system collapse. Voltage collapse is

An Improved Algorithm for Optimal Load Shedding in Power Systems
Energies, 2018 A blackout is usually the result of load increasing beyond the transmission capacity of the power system. A collapsing system enters a contingency state before the blackout.

Computational intelligence based power tracing for non discriminatory losses charge allocation and voltage stability improvement / Zulkiffli Abdul Hamid [PDF]
, 2013 This thesis proposes a new power tracing technique using computational intelligence approach for non discriminatory losses charge allocation and voltage stability improvement. Contrary to conventional techniques which mainly rely on matrix operation, the

Optimal SVC allocation via symbiotic organisms search for voltage security improvement [PDF]
, 2019 It is desirable that a power system operation is in a normal operating condition. However, the increase of load demand in a power system has forced the system to operate near to its stability limit whereby an increase in load poses a threat to the power ...

Advanced control scheme and dynamic phasor modelling of grid‐tied droop‐controlled inverters
IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.Abstract This paper develops an advanced scheme, modelling, and analysis of power flow control intended for grid‐connected droop‐controlled VSIs within a single‐phase microgrid (MG). The proposed control scheme includes a power calculation method based on an enhanced second‐order generalized integrator frequency‐locked loop (ESOGI‐FLL). Contrary to the

IET Generation, Transmission &Distribution, Volume 8, Issue 5, Page 924-934, May 2014., 2014 Voltage stability improvement is a challenging issue in planning and security assessment of power systems. As modern systems are being operated under heavily stressed conditions with reduced stability margins, incorporation of voltage stability criteria in the operation of power systems began receiving great attention.

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.This paper suggests the optimal placement of different flexible alternating current transmission system (FACTS) devices using various metaheuristic methods associated with effective cost management in the distribution network. The outcomes show that the proposed WOA technique generates more upshot than any other evolutionary algorithms in cost ...
