Impact Of Wind Power On Stability Of Offshore Platform Power Systems

Wind turbine generator systems can be including in conventional isolated power systems such as offshore oil platform power systems to significantly lower operating costs due to increased fuel savings. It is quite evident that limitations in the wind energy and its intermittent behavior degrade system stability. Wind power penetration can significantly reduce the system fuel costs but can also have considerable impact on the system stability. In this paper, the stability assessment of an isolated offshore oil platform power system with wind power based PSCAD/EMTDC is presented. The simulation results show that the wind power expansion in the isolated offshore oil platform power system with three synchronous generators driven by gas turbines can keep the system voltage and frequency stability at a desired level. Grid connection experiments between the offshore oil platform power system and wind turbine generators supported by CNOOC will prove the impact of connection of wind power on the voltage and frequency stability can be accepted lately.
