The increasing penetration level of wind generation in power systems has resulted in the degradation of the system frequency response and stability issues, where the decrease of the system equivalent inertia is one of the main causes of these problems. In this context, this work proposes an operational and control approach to provide emulated inertial response to wind turbine generators based on fully rated converter that operate at the maximum power point. The inertial response of the wind turbine generator is extended by a control strategy that combines an adaptive MPPT control with an adaptive inertia control based on virtual synchronous generator. The proposed approach mitigates the antagonistic interaction between the traditional MPPT control and inertia control. The impact of the MPPT control and inertia control on the dynamics of the wind turbine and system frequency is comprehensively addressed. The results have shown that the proposed strategy is effective in extending the inertial response of the wind turbine generator and mitigating the amplitude of the second frequency dip and electromechanical oscillations caused by the conventional MPPT control. The adaptive inertia control also prevents the violation of the minimum speed limit of the wind turbine

风力发电在电力系统中的渗透水平不断提高，导致系统频率响应和稳定性问题的恶化，其中系统等效惯量的降低是导致这些问题的主要原因之一。在这种情况下，这项工作提出了一种操作和控制方法，为基于在最大功率点运行的全额定转换器的风力涡轮发电机提供模拟惯性响应。风力涡轮发电机的惯性响应通过将自适应 MPPT 控制与基于虚拟同步发电机的自适应惯性控制相结合的控制策略进行扩展。所提出的方法减轻了传统 MPPT 控制和惯性控制之间的对抗性相互作用。全面解决了 MPPT 控制和惯性控制对风力涡轮机动力学和系统频率的影响。结果表明，所提出的策略在扩展风力涡轮发电机的惯性响应和减轻由传统 MPPT 控制引起的二次频率骤降和机电振荡的幅度方面是有效的。自适应惯性控制还可以防止违反风力发电机的最低速度限制
