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 ...
