摘要：
A method based on an equivalent frequency response model for analyzing the wind power pene⁃ tration limit （WPPL） in offshore oilfield power systems is proposed. The average system frequency response （ASFR） equivalent model of offshore oilfield power systems is developed. The parameters of prime mover and governor are determined based on the single- and twin-shaft gas turbine. The probability model of wind power fluctuation is established according to the differential transformation and t location-scale distribution. Then，based on the indicator of allowing cumulative probability of wind power fluctuation and the indicator of maximum frequency variation after the most serious fault，the WPPL analyzing method considering fre⁃ quency deviation constraints and transient frequency stability constraints is proposed. The accuracy and effec⁃ tiveness of the proposed method are verified using the actual offshore oilfield power systems，and the results demonstrate that the response speed of prime mover and governor and the transient frequency stability con⁃ straints have critical impacts on the WPPL in offshore oilfield power systems. © 2023 Electric Power Automation Equipment Press.
