Floating energy islands on scaleable and adaptable modular foundations have been seen as a transformative technology for offshore installation of renewable assets, integrating wind, wave, solar, and current dependent resources. To ensure smooth and fault-resistant operation across dynamically varying marine environments, applications of microgrid design and grid-forming inverter technologies have come increasingly under spotlight. In this work, the role of microgrids and grid-forming inverters to facilitate independent control, system stability, and energy interoperability is examined. Emphasis is placed on structural and functional integration of power systems in floating platforms with challenges regarding harsh environmental loads, modular expansion, and inter-platform coordination of energy. Grid-forming inverters are explored for their ability to provide virtual inertia, black-start, and seamless transition between grid-connected and islanded modes. Moreover, integration of energy storage and system-level robustness are analyzed from techno-economic viability and reliability perspectives. It is demonstrated that the synergy of modular design concepts, intelligent control, and distributed energy resources can facilitate the development of regulation-compliant, self-sustaining, and structurally robust offshore energy infrastructures. In this study, a microgrid consisting of five nodes and four branches has been modeled, in which consumers and producers are randomly distributed throughout the network. The model incorporates micro-inverter integration to enhance system flexibility and performance. The topology is defined by n +1 nodes and n branches. In scenarios where the ratio of energy generated by the distributed sources to the energy consumed exceeds unity, surplus power is transferred to the main grid.
