Abstract: Aiming at the frequency stability problem of the offshore oilfield power systems (OOPSs) caused by the integration of offshore wind power, this paper proposes a solution based on the distributed wind-storage integrated system (DWSIS). Firstly, based on a real OOPS, the model of DWSIS is constructed as well as the grid it integrated into. Then, the principle and analysis method are proposed of DWSIS to improve the frequency stability of the grid. Finally, the effectiveness of the DWSIS is verified via electromagnetic transient simulation. The DWSIS proposed can be expected to improve the frequency stability of the OOPSs with high penetration of wind power and promote the low-carbon development of offshore platform production.
