Abstract: A method and system of controlling a power converter operatively coupled with an electric grid, includes: operating the power converter in a direct power control mode with a dynamic switching table, the dynamic switching table including a group of converter space vectors and switching rules associated with the grid voltage and the dc-link voltage of the power converter; detecting abnormalities in the grid voltage and/or the converter dc-link voltage due to a grid fault event relative to their nominal operating conditions; determining a group of crossover angles for a group of converter vectors including the nearest three vectors to a grid voltage vector location inside a hexagonal space vector diagram; dynamically selecting a proper vector based on algorithmic feedforward of the group of crossover angles to dynamically construct the dynamic switching table; and controlling an output power of the power converter.
