Adaptive Nonlinear PID Controller for Boosted Load Frequency Management of Grids With Renewables and Energy Storage Units

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
Adaptive nonlinear PID controller as a promising control scheme is introduced. Two nonlinear gains based on the configurable hyperbolic functions are used. SFS algorithm is employed to calibrate controller gains optimally. Performance gained is tested on various power grids enriched by RESs and ESUs.
