摘 要
随着可再生能源的广泛接入和电力负荷的日益复杂化，传统电力系统负荷频率控制方法面临诸多挑战，难以适应现代电网的动态特性和不确定性需求。为此，本文提出了一种基于模糊控制的电力系统负荷频率控制策略，旨在提升系统的鲁棒性和控制性能。研究通过构建模糊逻辑控制器，结合系统实时运行数据与专家经验规则，有效应对负荷波动和参数不确定性问题。同时，引入自适应调整机制优化模糊隶属度函数，进一步增强了控制策略的适应能力。仿真结果表明，该方法在多种工况下均能显著改善频率偏差和功率不平衡现象，相较于经典PID控制和其他智能控制方法，展现出更优的动态响应特性和稳态精度。此外，所提策略无需精确数学模型即可实现高效控制，降低了对系统建模的依赖性，具有较强的工程应用价值。本文的研究为复杂电力系统中的频率控制提供了新思路，为实现高渗透率可再生能源环境下的稳定运行奠定了理论基础。

Abstract
With the extensive integration of renewable energy and the increasing complexity of electrical loads, traditional load frequency control methods for power systems face numerous challenges and struggle to accommodate the dynamic characteristics and uncertainty requirements of modern grids. To address these issues, this paper proposes a load frequency control strategy for power systems based on fuzzy control, aiming to enhance the robustness and control performance of the system. By constructing a fuzzy logic controller that integrates real-time operational data with expert experience rules, the proposed method effectively handles load fluctuations and parameter uncertainties. Additionally, an adaptive adjustment mechanism is introduced to optimize the fuzzy membership functions, further strengthening the adaptability of the control strategy. Simulation results demonstrate that this approach significantly improves frequency deviations and power imbalances under various operating conditions, exhibiting superior dynamic response characteristics and steady-state accuracy compared to classical PID control and other intelligent control methods. Moreover, the proposed strategy achieves efficient control without requiring an accurate mathematical model, reducing dependence on system modeling and showcasing strong engineering application potential. This study provides new insights into frequency control in complex power systems and lays a theoretical foundation for stable operation in high-penetration renewable energy environments.
