The aim of the contribution is to present a new method for the control of the active and non-active instantaneous power for the grid-connected voltage source converter. The GPPC (Generalized Predictive Power Control) is examined in the paper. A design procedure, simulation results, and experimental validation of the GPPC are presented. This GPPC application belongs among predictive control strategies for multi-input multi-output systems with some time varying coefficients. The responses following changes in the power references as well as after disturbances in the grid voltage are presented and evaluated. The simple implementation, long prediction horizon, and also resistance to parameter changes and to unbalanced grid conditions belong among advantages of the method. The determination of the GPPC parameters is not dependent on the AC/DC converter circuitry and on the PWM applied. The developed GPPC used in the converter connected to the grid can be considered as an original contribution to the problem of controlling the dc/ac converter performance.
