Resumen:
A Grid-Voltage sensorless control strategy for LCL Grid-connected voltage source inverters is proposed. Positive and negative grid sequences used for synchronization are estimated using an observer. The control of the system is implemented with a strategy that allows the use of the proportional plus resonant regulator (PR) optimum design, regardless of the filter resonance frequency. The effectiveness of the proposal is demonstrated by simulation in a realistic scenario.
