Enhancing Islanded Microgrid Resilience: Super-Twisting Algorithm with Hopf-based Inverter Synchronization

This paper presents super-twisting sliding mode control (ST-SMC) integrated with a Hopf oscillator for islanded microgrids. The ST-SMC is realized to reduce the effect of uncertainties due to parameter variation in coordination with the Hopf oscillator for synchronization among inverters. This approach provides robustness to the system and contributes overall system performance and enhances stability. The mathematical analysis and simulated results of this control technique are presented.
