A method for controlling power flow of an electric power generation system (10) includes generating or dissipating electric power to maintain a predetermined grid voltage and frequency. The electric power is transmitted to a grid (20); and the current and voltage of the electric power thus transmitted are sensed. The frequency of the grid (20) and the power transmitted to the grid (20) is determined based on the sensed current or voltage. A grid-side converter (42) is then controlled to regulate the voltage and frequency of an electric grid (20) via a compensating circuit (52) when the sensed voltage is outside a predetermined voltage range or the determined frequency is outside a predetermined frequency range. |
