This contribution presents a smart power electronics injection system for grid-connected photovoltaic energy resources. The developed converter can not only inject the maximum active power as a typical inverter does, but also provide the active functions the Smart Grid scenario needs, including reactive power reference tracking for compensating purposes, node voltage regulation for helping the grid...
This study presents a new single-phase topology for the power injection system of a grid-connected photovoltaic generation system that is based on the parallel association of two voltage-source inverters: one is a three-level inverter with clamping diodes (or neutral point clamped) with a low switching frequency strategy (equal to the grid frequency) and the other is a two-level inverter which operates...
