Intelligent Impedance‐Based SSR Mitigation in Photovoltaic Systems via Genetic Algorithm Optimization

open access: yesIET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel impedance‐based approach for mitigating sub‐synchronous resonance (SSR) in grid‐connected photovoltaic systems. A supplementary virtual impedance controller, optimized using a genetic algorithm, is designed to adaptively damp SSR under varying operating conditions, with performance validated through eigenvalue, impedance ...

Optimal Placement and Sizing of Series and Shunt Compensation for Improving Power Systems Operation

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
Power systems are complex, and power demand has constantly increased over time. Moreover, power transmission systems have a limited capacity, causing the increase in demand to be difficult to accommodate. Additional system requirements include maintaining voltages within specific values and limiting voltage drop in the lines to ensure voltage stability,

Distributed Static Series Compensators (DSSCs) in Modern Power Systems: A Systematic Literature Review

open access: yesInternational Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
Distributed static series compensators (DSSCs) are modular power‐electronic devices that dynamically regulate transmission‐line reactance by injecting a controlled quadrature voltage. This paper presents the first comprehensive systematic literature review focused exclusively on DSSCs, covering studies published from 2004 to 2024.
