The integration of renewable energy sources into the goal of sustainable energy significantly alters power systems, necessitating the development of innovative approaches to ensure grid stability. The emergence of grid-forming technology is a disruptive approach that deviates from conventional grid-following methods, facilitating autonomous operation. The decoupling of power generation from frequency and voltage enables the utilization of decentralized resources such as solar energy, hence improving grid stability in the face of variations caused by renewable sources. This paper examines current developments in various aspects, including principles, control techniques, microgrid resilience, flexibility in both grid-connected and islanded modes and the problems associated with these breakthroughs. It highlights the significant capacity of grid-forming converters to drive transformational changes in the development of resilience. It is strongly recommended that stakeholders from academic, business, and policy sectors use this technology to facilitate the smooth integration of renewable energy sources and ensure the power grid’s resilience.
