This study deals with the problem of voltage security in microgrids. In general, is an issue for power systems, where lack reactive a concern. For microgrids complexity imposed, since frequency and level deviations may take place by operation droop‐controlled inverters. incorporates load margin calculation into microgrid structure. this purpose, special flow program developed order to consider effects Simulation results are obtained help islanded distribution system only generators coupled inverters, so proposed methodology be tested discussed.
