摘　　要：伴随着更高的风速和更广阔的发展空间,深远海海上风电展现出了巨大的发展潜力。为解决风速和风功率波动影响下深远海海上风电接入海上平台电力系统时面临的可靠性和优化问题,首先研究海上不同高度层风速的相关性,建立不同高度层风速和10 m高度层风速的关系;随后提出一种风储优化调度方法,考虑系统可靠性、储能限制等约束条件,采用模型预测控制算法对调度模型进行求解;最后应用Roy Billinton可靠性测试系统(Roy Billinton test system,RBTS)验证风电接入对系统可靠性的影响和所提风储调度模型的有效性。研究结果表明,轮毂高度的风速修正对系统可靠性评估具有重要性意义,合理利用储能并调度其储能的出力可以显著提升其可靠性,为深远海海上风电可靠性评估研究提供有益补充。With higher wind speeds and broader development space,deep-sea offshore wind power demonstrates significant potential for growth.To address the reliability and optimization challenges associated with integrating deep-sea offshore wind power into marine platform power systems under the impact of wind speed and wind power fluctuations,initially,the correlation between wind speeds at different heights above sea level is investigated,establishing a relationship between wind speeds at various heights and those at 10 meters.Subsequently,an optimized wind power storage dispatching method is proposed.By considering the system reliability,energy storage limit,and other constraints,the model predictive control algorithm is used to solve the dispatching.Finally,the Roy Billinton test system(RBTS)system is utilized to verify the impact of wind power integration on system reliability and the effectiveness of the proposed wind power storage dispatching model.The results indicate that the wind speed correction at hub height is crucial for system reliability evaluation.The rational utilization and dispatching of energy storage can significantly enhance reliability,providing a valuable supplement to the reliability evaluation of deep-sea offshore wind power.
