Resumen

© 2016 IEEE. Grid-connected inverters are an essential component of modern photovoltaic systems. They allow the users to obtain a faster recovery of the investment given their capability of injecting the excess of generated energy to the grid. Proper operation of the inverters requires a current loop with the capability to deal with eventually distorted grid voltages and with LCL coupling filters. This makes the control much more sensitive to errors or delays in the values of the control variable. In this paper a real-time digitally implemented technique is proposed to obtain a reconstructed version of grid voltage which can be used as a feedforward signal in the current loop of a grid-connected inverter.
