Cheetah Optimizer based PIDA Controller Design for Cyber-physical Power System under Cyberattacks and Uncertainty

This paper presents a cheetah optimizer (CO) based PIDA controller scheme for frequency regulation of cyber-physical microgrid. CO is recently proposed nature inspired optimization algorithm. CO benefits in the terms of global optimization and few design parameters. The frequency control is important concerned regarding balance between generation of power and power demand in power system with high integration of the renewable-energy resources (RESs). Currently, power system is more dominated on the communication networks. So, the cyber-attacks have been raised in the current power system. The proposed control design is mitigated the effects of parametric uncertainty, cyber-attack, time-delays and random load-demand. Analysis based on simulation studied reveals the benefits of proposed LFC design under various practical cases.
