This paper uses the master stability function methodology to analyze the stability of synchrony in microgrids of arbitrary size and containing arbitrary control systems. . Such schemes fall into two broad categories: so-called “grid-following” controllers that seek to match output ac power with grid frequency, and “grid-forming” systems that seek to boost grid stability. The latter frequently work by providing synthetic inertia, enabling dc renewable sources to. . efinitions, Analysis, and Modeling [1], which defines concepts and identifies relevant issues related to stability in microgrids. However, the design, control, and stability analysis of. . Their topology is becoming increasingly decentralized due to distributed, embedded generation, and the emergence of microgrids. Grid dynamics are being impacted by decreasing inertia, as conventional generators with massive spinning cores are replaced by dc renewable sources.
