Dynamic Stability Analysis of Synchronverter-Dominated Microgrid Based on Bifurcation Theory Dynamic Stability Analysis of Synchronverter-Dominated Microgrid Based on Bifurcation Theory   Abstract— In the traditional power grid, inverter-interfaced distributed energy resources (DERs) are widely used in microgrids such as conventional synchronous generators (SGs) in the traditional power grid. They are expected to decrease the rotational inertia and spinning reserve capacity that are specific to SGs, while synchronverters can compensate for the loss. Thus, an increasing number of interfaced inverters may act as synchronverters…

Design of Modified Droop Controller for Frequency Support in Microgrid using Fleet of Electric Vehicles Design of Modified Droop Controller for Frequency Support in Microgrid using Fleet of Electric Vehicles Abstract— Droop control has been extensively used by academia and industry for managing frequency fluctuations at microgrid (MG).
