Abstract: Microgrids (MGs) are building blocks of smart power systems formed by integrating local power generation resources, energy storage systems (ESSs), and power-consuming units. While MGs offer many benefits, including increased resilience and flexibility, there remains a need for improved control and protection techniques that
