Given the increasing penetration of wind power generation, the power system faces great challenges in frequency regulation due to reduction in system inertia. This paper proposes an adaptive power compensation based frequency regulation (FR) strategy of the wind turbine system (WTS). In a frequency transient event, the proposed strategy exploits power excitation method to estimate the disturbance level, which enables the WTS to timely and accurately participate in FR. After the system frequency and the rate of change of frequency meet their requirements, the droop control is adopted to smooth the WTS out of the FR mode and further improve the frequency quality. By analyzing the operation mode and determining the switching logic, detailed implementation of the proposed strategy is developed. Its excellent frequency response performance is verified via results of hardware-in-the-loop experiment and MATLAB/Simulink-based simulation.

基于自适应功率补偿的风电机组调频策略


随着风力发电的普及，电力系统因系统惯性的降低而面临着调频的巨大挑战。本文提出了一种基于自适应功率补偿的风力涡轮机系统（WTS）频率调节（FR）策略。在频率瞬变事件中，该策略利用功率激励方法来估计扰动水平，使得WTS能够及时、准确地参与FR。当系统频率和频率变化率满足要求后，采用下垂控制使WTS平滑脱离FR模式，进一步提高频率质量。通过分析操作模式并确定切换逻辑，制定了所提出策略的详细实现。通过硬件在环实验和基于MATLAB/Simulink的仿真结果验证了其优异的频率响应性能。
