Inverter self-frequency reduction and grid connection
Abstract—This paper develops an integrated synchronization control technique for a grid-forming inverter operating within a microgrid that can improve the microgrid's transients during microgrid transition operation. Unlike grid-following inverters, which rely on phase-locked loops (PLLs) for synchronization and require a stable grid connection, GFMIs internally. . To address above mentioned shortcomings, we leverage the intrinsic synchronization and power sharing capabilities of coupled nonlinear Andronov-Hopf oscillators (AHOs) to constitute the decentralized controller of the series-stacked system [22].
