摘要

为提高光伏储能系统的响应速度和抗干扰能力,以储能侧双向DC-DC变换器为研究对象,提出一种基于自适应规则的协调自抗扰稳压控制策略。首先,建立双闭环线性自抗扰控制（LADRC）结构,通过变化控制器参数初始值协调内外环间的影响程度。其次,以规则设计作为参数优化机制对外环控制器参数进行在线自适应调整,进一步提升系统的快速性和准确性。仿真分析及实验结果表明,在保证系统稳定性及不改变调参复杂性的前提条件下,采用自适应协调自抗扰控制策略在信号跟踪性能、抗扰性能、抗噪性能上均优于传统控制策略。

Abstract

To improve the dynamic performance and anti-interference ability of photovoltaic energy storage systems, a coordinated self disturbance rejection and voltage stabilization control strategy based on adaptive rules is proposed, taking the bidirectional DC-DC converter on the energy storage side as the research object. Firstly, establish a dual closed-loop ADRC structure to coordinate the degree of influence between the inner and outer loops by changing the initial values of the controller parameters. Secondly, rule design is used as a parameter optimization mechanism to adaptively adjust the parameters of the external loop controller online, further improving the system's speed and accuracy. Simulation analysis and experimental results indicate that the adaptive coordinated Active disturbance rejection control strategy is superior to the traditional control strategy in signal tracking performance, disturbance rejection performance and noise rejection performance under the premise of ensuring system stability and not changing the complexity of parameter adjustment.
