This work presents the control design guidelines of a passivity-based control of the active and the reactive power in single-phase PV inverters. The control ensures global asymptotic convergence of the tracking error to zero and the PV inverter shows robust current tracking with fast dynamics. The control is particularized in the cases of strong and weak grid operation. In the last case, the knowledge of the grid impedance and the injected active power allows to calculate the value of the required reactive power in order to set the amplitude of the voltage at the connection point to the ideal grid amplitude. The control is validated by means of numerical simulations when the power references are changed and when the PV irradiance varies.
