Metaheuristic‐Based Load Frequency Control of Multi‐Source Renewable Systems With SMES and AC‐DC Parallel Tie‐Lines

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study proposes a hybrid evolutionary exploration algorithm (HEEA) that integrates genetic algorithm and grey wolf optimiser to co‐tune PID controller gains and SMES parameters in a two‐area AC‐DC interconnected renewable system. The proposed method achieves faster convergence, lower ITAE and improved stability compared to existing metaheuristics ...

PHEVs Park as Virtual UPFC

TELKOMNIKA Indonesian Journal of Electrical Engineering, 2012
Unified power flow controllers (UPFCs) are FACTS devices which can fulfil multiple power-flow control objectives, such as the need for reactive shunt compensation, phase shifting and series compensation. However, as they are quite expensive, they are not widely used.

Addressing Distance Relay Mal‐Operation in Low‐Inertia Grids: A PLL‐Informed Power Swing Assessment

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
A key advantage of the proposed approach is its independence from PLL control settings, relying solely on locally measured electrical quantities, which ensures robust, fast, and practical implementation in existing commercial distance relays. ABSTRACT The increasing penetration of inverter‐based resources (IBRs) has substantially reduced system inertia

Overvoltage Suppression Strategy for HPFC Based on Bandwidth Adaptive LADRC and Improved Reactive Power Control

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
Overvoltage occurs in Hybrid Power Flow Controllers (HPFC) under specific fault conditions. This paper proposes a linear Active Disturbance Rejection (LADRC) strategy integrating reactive power adaptive regulation and bandwidth parameter adaptive adjustment to suppress whole‐process overvoltage in HPFC.
