Control of power electronic converters for distributed generation units

The traditional power systems are changing globally, a large number of dispersed generation (DG) units are being integrated into power systems at distribution level. Power electronic, the technology of efficiently processing electric power, plays an essential part in the integration of the dispersed generation units for good efficiency and high performance of the power systems. This paper describes the frequency and voltage control of the power systems with the power electronic interfaced generation units. A control scheme is proposed. Simulation study has been performed and the results show the good performance of the control scheme.
