随着电网规模的不断扩大、结构的不断变化、可再生能源的不断整合以及互联电力系统的日益复杂，负荷频率控制问题变得越来越重要。本文对基于LFC的自抗扰控制器（ADRC）进行了评估。这种控制算法提供了一种新的设计概念和固有的鲁棒控制器构建块，它只需要很少的系统信息。它主动估计和补偿未知动态和干扰的影响。该控制策略首先应用于一个孤立的电源区域，然后应用于三个互联的控制区域。仿真结果表明，所采用的控制器能够最大限度地减少负荷变化和风力穿透所引起的干扰的影响，从而保持鲁棒性能和电网稳定性。
The load frequency control (LFC) problem is becoming more significant today in accordance with increasing grid size, changing structure, integration of renewable energy sources, and complexity of interconnected power systems. In this paper the assessment of Active Disturbance Rejection Controller (ADRC) based LFC is presented. This control algorithm offers a new design concept and inherently robust controller building block that requires very little information about the system. It actively estimates and compensates for the effects of the unknown dynamics and disturbances. The control strategy was applied to a single isolated power area and then to three interconnected control areas. The simulation results showed that the used controller was able to maintain a robust performance and grid stability by minimizing the effect of disturbances caused by load variation and wind power penetration.
