Abstract—AC Microgrids, in presence of highly non-linear loads, require a tighter regulation of line voltage to maintain power quality. This article proposes an outer virtual impedance loop to shape the output voltage in such microgrids. In order to achieve this, a virtual impedance extracting and. . Continuously expanding deployments of distributed power generation systems are transforming conventional centralized power grids into mixed distributed electrical networks. The higher penetration and longer distance from the renewable energy source to the main power grid result in lower grid. . With the rapid development of electrical power systems in recent years, microgrids (MGs) have become increasingly prevalent.
