摘要：
This work presents the design guidelines of a control for direct regulation of the voltage amplitude at the connection point of a single-phase grid-connected PV inverter. The parameters of the control are designed for ensuring local asymptotic stability for a given range of the impedance. Furthermore, the control includes a strategy of active power curtailment in order to avoid the injection of a large amount of reactive power to the grid. Numerical simulations confirm the expected voltage regulation and the control robustness with respect to the grid impedance variations without the requirement of any estimation or measure of the actual impedance.
