| Abstract |
Highlights: This research develops a frequency control method, robust against parameter uncertainties, for islanded microgrids. The control method can also withstand the impact of cyberattacks and ensure reliable and secure operation. What are the main findings? The denial-of-service threat is modeled by the Bernoulli stochastic variable. A new sufficient condition is developed to design the controller in terms of linear matrix inequalities. What is the implication of the main findings? A microgrid frequency norm-bounded model representing parameter uncertainty and cyberattack is developed. Various testing scenarios demonstrate the suggested controller’s efficacy. To meet the requirements of a smart city in supporting a sustainable high-quality lifestyle for people, there is a need for many smart technologies and smart grids. A smart grid integrates electrical and digital technologies, information, and communication. Microgrids (MGs) are the main components of smart grids. The proposed control scheme introduces a robust control mechanism against model uncertainties and is secure against communication cyberattacks. A novel design criterion is formulated as linear matrix inequalities (LMIs) to provide the required state feedback with integral control. In contrast to the conventional H∞ control approach, the suggested tracker offers enhanced disturbance attenuation and a faster response. Different testing scenarios demonstrate the successful performance of the suggested controller. © 2025 by the authors. |
