Management of a Dual-Bus AC+DC Microgrid Based on a Wind Turbine with Double Stator Induction Generator

The topology and management of a sustainable dual-bus, AC DC, microgrid designed to operate connected weak grid is presented. AC+DC hybrid microgrids are robust cost-competitive solution for poorly areas, as can be found in rural or island electrification. versatile proposed this work developed around wind turbine based on particular induction generator with double stator winding squirrel cage rotor (DWIG). This singular especially suitable combined coupled application. One its windings the DC bus via controlled AC/DC converter. other directly bus, only during periods abundant resource. DWIG complemented photovoltaic panels energy storage system, comprising flow batteries assisted by supercapacitors, which converge Bus. exchanges power through an interlinking inverter. article describes details operation Supervisory Control gives rise five operating modes microgrid. Its performance under different generation conditions load regimes thoroughly assessed simulation.
