Can grid-connected PV inverters improve utility grid stability?
Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
Two power converters—a boost DC–DC converter and a PV inverter—are used to connect PV arrays with the grid . A boost converter controls the PV power extraction . A Maximum Power Point Tracking (MPPT) method is applied in the boost converter by adjusting the PV voltage Vpv at the PV array's MPP to maximize solar energy generation.
