Complexity, Volume 2022, Issue 1, 2022., 2022 Sub‐Saharan emerging countries experience electrical shortages resulting in power rationing, which ends up hampering economic activities. This paper proposes an approach for very short‐term blackout forecast in grid‐tied PV systems operating in low reliability weak electric grids of emerging countries. A pilot project was implemented in Arusha‐Tanzania;

Key performance‐cost tradeoffs in smart electric vehicle charging with distributed generation
IET Smart Grid, Volume 4, Issue 6, Page 561-581, December 2021., 2021 Abstract Growing penetration of Electric Vehicles (EV) and Distributed Generation (DG) is driving sharper peaks in demand and supply, which, if poorly managed, manifest as over‐ or undervoltage and disrupt grid service quality. Smart charging schemes reschedule EV charging load according to factors such as grid stability, price signals, etc. It remains

A two‐stage service restoration method for electric power distribution systems
IET Smart Grid, Volume 4, Issue 5, Page 500-521, October 2021., 2021 Abstract Improving the reliability of power distribution systems is critically important for both utilities and customers. This calls for an efficient service restoration module within a distribution management system to support the implementation of self‐healing smart grid networks.

Adaptive wide-area closed-loop undervoltage load shedding using synchronized measurements [PDF]
IEEE PES General Meeting, 2010 This paper proposes an emergency load shedding scheme aimed at stopping a developing voltage instability before system disruption. The proposed scheme has a wide-area view of the system, adapts itself to the emergency situation to be handled, and works in closed-loop.

Design of an undervoltage load shedding scheme for the Hydro-Quebec system [PDF]
2003 IEEE Power Engineering Society General Meeting (IEEE Cat. No.03CH37491), 2004 This paper deals with the control logic of an undervoltage, closed-loop load shedding scheme aimed at protecting the Hydro-Quebec system against long-term voltage instability. This scheme relies on a set of "if-then" rules whose parameters are determined through combinatorial optimisation, relying on the system dynamic response over a set of scenarios.

Local vs. wide-area undervoltage load shedding in the presence of induction motor loads [PDF]
2009 IEEE Bucharest PowerTech, 2009 In the presence of induction motor loads, long-term voltage instability may end up in a sharp voltage decrease, which makes the tuning of undervoltage load shedding more delicate. This paper first investigates the ability of a purely distributed load shedding scheme, previously proposed by the authors, to cope with these situations.

Impact of Cyberphysical Attacks on Load Tap Changers and Distribution System Voltage Stability
IET Smart Grid, Volume 9, Issue 1, January/December 2026.In this paper, we analysed the impact of a cyberphysical attack manipulating the operation of the LTC. In addition, we analysed the effect of load drop and PV while LTC is being manipulated. The cyber vulnerabilities leading to the attack were explored. ABSTRACT Load tap changers (LTCs) play a critical role in voltage regulation, and their manipulation

Soft Open Points for Optimising Flexibility Exploitation in Power Distribution Networks
The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.The paper considers soft open point (SOP) as a valuable solution for enabling flexibility exploitation provided by distributed energy resources (DERs). A linear‐programming operational planning framework is presented to quantify the value of coordinating SOPs with DERs for flexibility‐oriented operation of distribution networks.
