This paper introduces a hybrid control method designed to address two significant challenges in microgrid (MG) applications: active resonance damping (ARD) and unbalanced voltage compensation (UVC). Furthermore, the proposed hybrid method combines effective ARD with UVC at MG. . Abstract—The increasing penetration of inverter-based re-sources (IBRs) calls for an advanced active and reactive power (PQ) control strategy in microgrids. The low PCC voltage has a larger impact for Strategy I because its power control loop is a current control loop, and the current references depend on the PCC voltage. Strategy II has a. . Nowadays, the microgrid (MG) concept is regarded as an efficient approach to incorporating renewable generation resources into distribution networks. However, managing power flows to distribute load power among distribution generators (DGs) remains a critical focus, particularly during peak demand. . used in a microgrid? Encouraged by the aforementioned analysis,a novel intelligent P-Q control method is proposed for three-phase grid-connected inverters in a microgridby using an adaptive population-based extremal verter in microgrid? Since we are using the topologies of directly connected. . 12] are developed for microgrid.
