Özet

The focus of this work revolves around the active-reactive power sharing problem in islanded microgrids, an area where research in Inverter-Based Resources (IBRs) is currently thriving. To mitigate the active-reactive power sharing issue and enhance system stability and resilience, virtual impedance and voltage-frequency restoration are employed. However, the tuning of parameters that arise during specific state transitions, such as load addition and shedding, is accomplished through particle swarm optimization (PSO). Simulation and comparative results demonstrate the improvements introduced by the application of PSO-based frequency and voltage restoration in this paper.
