摘　　要：在多重不确定性风险因素共同作用下,风电机群调峰调频效果与预期效果偏差较大,加大了运营难度。为解决这一问题,提出了双馈型风电机群调峰调频混合控制仿真方法。建立双馈型风电机群多重不确定性风险模型、多重不确定性风险下风电机群出力置信度评估、建立双馈型风险机群控制数学模型、调峰调频混合控制策略。通过对控制过程中全局参量与变量的关联分析与优化,实现调峰调频的混合控制效果。测试结果表明,方差权重始终小于等于1。证明本文方法能够有效提升风电机群在不确定性风险下的调峰调频控制精准度与稳定性,具有较好的应用价值。Under the combined effect of multiple uncertain risk factors,the peak shaving and frequency regulation effect of wind turbine groups deviates significantly from the expected effect,increasing the difficulty of operation.To solve this problem,a simulation method for peak shaving and frequency modulation hybrid control of doubly fed wind turbine groups was proposed.Established a multi uncertainty risk model for a doubly fed wind turbine group,evaluated the output confidence of the wind turbine group under multiple uncertainty risks,established a mathematical model for the control of a doubly fed risk turbine group,and implemented a hybrid control strategy for peak shaving and frequency regulation.By analyzing and optimizing the correlation between global parameters and variables in the control process,the hybrid control effect of peak shaving and frequency modulation can be achieved.The test results indicate that the variance weight is always less than or equal to 1.Prove that the method proposed in this article can effectively improve the accuracy and stability of peak shaving and frequency regulation control of wind turbine groups under uncertainty risks,and has good application value.
