Hybrid AC/DC microgrids have emerged as a promising solution for integrating diverse renewable energy sources, enhancing efficiency, and strengthening resilience in modern power systems. Besides, the lack of inertia caused by droop and phase-locked loop-based current control brings negative effects to the system. We propose a distributed normalized power coordination. . Abstract: This paper describes a hybrid ac/dc micro grid that may be used to decrease the procedures of many dc-ac-dc or ac-dc-ac conversions in a single ac or dc grid. The hybrid grid is made up of both alternating current and direct current networks that are linked together by multi-bidirectional. . This paper presents a distributed control architecture for voltage and frequency stabilization in AC islanded microgrids. In the primary control layer, each generation unit is equipped with a local controller acting on the corresponding voltage-source converter.
