Advanced control scheme and dynamic phasor modelling of grid‐tied droop‐controlled inverters

open access: yesIET 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

Preventive control approach for voltage stability improvement using voltage stability constrained optimal power flow based on static line voltage stability indices

open access: yesIET 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.

Analysis of reactive power loadability and management of flexible alternating current transmission system devices in a distribution grid using whale optimization algorithm

open access: yesIET 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 ...

Prediction of Voltage Collapse in Electrical Power System Networks using a New Voltage Stability Index [PDF]

open access: yes, 2017
The numerous power system blackouts in the past decade and in recent times attest to the fact that more work still needs to be done to tackle the problem of voltage instability and the resultant voltage collapse.

Prediction of voltage stability index in buses without measurement in distribution systems

open access: yesIET Generation, Transmission &Distribution, Volume 18, Issue 14, Page 2435-2451, July 2024.
In this article, a new practical method called VFWMB is introduced for predicting voltage stability in the distribution system (DS). To implement this method, a practical algorithm is required to locate the measurements labelled seeking observation zone with the weight least square (SOZWLS).

An Improved Algorithm for Optimal Load Shedding in Power Systems

open access: yesEnergies, 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.

Voltage collapse prediction and control of a power system using hybridized classical probability theory and voltage stability indices

open access: yesDiscover Electronics
The incessant voltage collapse incidences on the Nigeria National grid is a serious concern. The primary dependability issue of voltage collapse makes it difficult to operate a reliable and secure power system network.
