Introduction

The increasing global demand for sustainable energy solutions, coupled with the need for enhanced grid resilience, has driven significant advancements in microgrid technologies [1,2]. Microgrids represent localized energy networks that can operate independently or in conjunction with the main grid, providing a reliable, efficient, and environmentally friendly power supply [3]. At the heart of these systems was the ability to transition between grid-connected and islanded modes, ensuring that power was continuously available, especially during grid disturbances or emergencies [4,5]. This transition, known as islanding, was a key feature of microgrids, and its integration with renewable energy resources, such as solar and wind power, was essential for fostering a sustainable energy future [6,7]. Through islanding, microgrids can operate autonomously, ensuring that critical infrastructure and services maintain power even in the event of a widespread outage [8]. Microgrids equipped with islanding capabilities offer a unique solution to the challenges of energy resilience and sustainability [9]. The integration of renewable energy sources within these systems was crucial for reducing dependency on conventional fossil fuels and lowering carbon emissions [10,11]. As renewable energy generation can be intermittent and variable, the incorporation of energy storage systems and advanced control algorithms becomes vital to ensuring continuous power availability and grid stability [12,13]. These systems manage the supply and demand of electricity, optimize the use of locally generated power, and maintain system balance despite fluctuations in renewable energy production [14-19]. In this context, microgrids not only contribute to reducing greenhouse gas emissions but also offer a pathway to a more reliable and resilient energy infrastructure [20,21].
