摘要
随着全球能源转型的推进，风电作为清洁能源的重要组成部分，在电力系统中的占比持续上升。然而，风电场并网给传统电力系统的稳定性带来了新的挑战。本文旨在研究风电场并网对电力系统稳定性的影响及控制策略，以确保大规模风电接入后电网的安全稳定运行。通过建立含风电场的电力系统仿真模型，采用时域仿真与特征值分析相结合的方法，深入探讨了风电场并网对功角稳定、电压稳定和频率稳定的影响机制。研究表明，风电场的随机性和间歇性特性显著影响着系统的动态响应，特别是在低惯量条件下，容易引发次同步振荡等问题。针对上述问题，提出了一种基于自适应鲁棒控制的风电场并网控制策略，该策略能够有效抑制系统振荡，提高暂态稳定性。创新点在于将自适应控制理论应用于风电场并网控制中，实现了对不确定性的实时补偿，增强了系统的抗干扰能力。此外，通过多场景仿真验证了所提控制策略的有效性和鲁棒性，为实际工程应用提供了理论依据和技术支持，对促进风电友好型电力系统的构建具有重要意义。

Abstract
With the advancement of global energy transition, wind power, as a crucial component of clean energy, has been increasingly integrated into power systems. However, the grid connection of wind farms poses new challenges to the stability of traditional power systems. This study investigates the impact of wind farm integration on power system stability and proposes control strategies to ensure safe and stable grid operation with large-scale wind power integration. By establishing a power system simulation model that incorporates wind farms, this research employs a combination of time-domain simulation and eigenvalue analysis to thoroughly examine the influence mechanisms of wind farm integration on power angle stability, voltage stability, and frequency stability. The findings indicate that the stochastic and intermittent characteristics of wind farms significantly affect the dynamic response of the system, particularly under low-inertia conditions, which can easily lead to subsynchronous oscillations. To address these issues, an adaptive robust control strategy for wind farm integration is proposed. This strategy effectively suppresses system oscillations and enhances transient stability. The innovation lies in applying adaptive control theory to wind farm integration control, achieving real-time compensation for uncertainties and strengthening the system's disturbance rejection capability. Furthermore, the effectiveness and robustness of the proposed control strategy are validated through multi-scenario simulations, providing theoretical basis and technical support for practical engineering applications and contributing significantly to the construction of wind-friendly power systems.
