Cheetah Optimizer based PID Controller Design for Islanded AC Microgrid under FDI Cyber-attack

In this paper a cheetah optimizer (CO) based PID controller design scheme for frequency regulation of an islanded AC microgrid is presented. The frequency control is important concerned regarding balance between power generation 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, cyberattacks have been raised in the current power system networks. CO is recently proposed nature inspired optimization algorithm. CO benefits in the terms of global optimization and few design parameters. The proposed control-design is mitigated the effects of parametric-uncertainty, cyber-attack and random load demand. The analysis based on simulation studied reveals the benefits of proposed LFC design under various practical conditions.
