| Abstract: |
| In order to analyze the resonance disturbance transmission mechanism between the inherent complex uncertainties of offshore wind power and the AC submarine cable transmission system, a resonance analysis method and suppression strategy for the AC transmission system of offshore wind power based on Fermatean fuzzy set is proposed. The impedance model of AC transmission system of offshore wind power is established by considering the grid-side converter control system of the offshore wind power and the distribution parameter model of the submarine cable, and the current-carrying capacity and voltage distribution characteristics of the long-distance AC submarine cable are investigated. The dominant factors of offshore wind power oscillation are analyzed from the interactive coupling of complex uncertainties such as inaccurate offshore wind power prediction, incomplete marine environmental information, and uncertainty of offshore transmission equipment parameters with the AC transmission system of offshore wind power. By introducing Fermatean fuzzy theory, combined with the acceptance domain, boundary domain and rejection domain of offshore wind power uncertainty factors, the interval parameter adjustment method considering offshore wind speed fluctuation, failure rate of AC transmission system and the changes in operating characteristic parameters is proposed. Then, the mechanism of offshore wind machine-grid interaction resonance phenomenon under the non-ideal grid conditions is analyzed, and the suppression measures are given. The correctness and effectiveness of the theoretical analysis results and the proposed method are verified by time-domain simulation. |
