摘要
随着风电渗透率的提高,系统的随机性进一步增强,而传统仅有常规机组提供调频备用的方式将导致系统备用的严重不足,因此本文重点研究了风电机组参与系统一次调频的自适应控制方式。首先,本文研究了风电机组预留一次调频备用的减载运行方式;其次,在传统风电机组一次调频控制方式的基础上,研究了风电机组参与一次调频的自适应控制方式,其虚拟惯性参数和下垂控制参数可随风电机组实际运行状态和系统频率变化进行自适应调节。研究表明,本文采取的自适应控制方式将使得系统的稳定性和安全性得到进一步提升。
With the increase of wind power permeability,the randomness of the system is further enhanced,while the traditional way of providing primary frequency regulation(PFR)reserve only for conventional units will lead to serious shortage of system reserve.Therefore,the adaptive control mode of wind turbine participating in PFR of the system is studied in this paper.Firstly,the de⁃loaded operation mode of reserving PFR reserve for wind turbines is studied.Secondly,the adaptive control mode of wind turbines participating in PFR is studied on the basis of traditional PFR control mode of wind turbines.Its virtual inertia parameters and droop control parameters can be adaptively adjusted with the actual operating state of the wind turbine and the system frequency.It is shown by the study that the adaptive control method adopted in this paper will further enhance the stability and security of the system.
