摘要

针对采用下垂控制的孤岛微电网因功率不平衡导致系统存在频率偏差或失稳的问题

基于Kuramoto模型设计孤岛微电网分布式二次频率控制策略。基于Kuramoto模型对孤岛微电网频率动态行为进行系统性建模

从系统层面进行频率控制设计。以频率无偏差为优化控制目标

采用PI一致性算法设计分布式二次频率控制器

各分布式电源仅需本地和相邻单元的信息

实现按照自身容量合理进行负荷有功功率分配。所提控制策略对通信网络中的延迟具有较强鲁棒性

此外采用Lyapunov直接法证明引入所提控制策略的微电网系统是渐近稳定的。通过Matlab/Simulink仿真验证多工况下所提控制策略的有效性

可减少系统频率偏差。

Abstract

To address frequency deviation or instability in islanded microgrids with droop control caused by power imbalances

a distributed secondary frequency control strategy based on the Kuramoto model was proposed. The Kuramoto model was employed to systematically model the dynamic behavior of frequency within the islanded microgrid and to design frequency control at the system level. The PI consensus algorithm was used to design the distributed secondary frequency controller

optimizing frequency deviation. Each distributed generation unit relied solely on local and adjacent unit information to achieve a rational distribution of active power loads according to its capacity. The strategy demonstrated robustness against communication network delays

and its asymptotic stability was proven using the Lyapunov direct method. Simulation under various operating conditions on the Matlab/Simulink platform verified the effectiveness of the proposed strategy in reducing system frequency deviation.
