摘要

背靠背模块化多电平换流器（MMC）在柔性直流输电系统中的工程应用日益广泛,其控制策略优化可抑制系统振荡、提升稳定性。首先搭建永磁直驱风电系统经背靠背MMC-HVDC并网仿真模型,监测直流电压与公共连接点交流电流质量,分析PI参数对并网稳定性的影响;随后针对关键PI控制器,提出准比例谐振（QPR）与非线性自抗扰控制（NLADRC）结合的结构,采用多目标改进鹭鹰优化算法（MOISBOA）优化参数;最后通过建立系统阻抗模型,验证了所提控制器的有效性。

Abstract

Back-to-back modular multilevel converter （MMC） has been applied widely to flexible DC transmission system, and its control strategy optimization can suppress system oscillation and improve stability. Firstly, the back-to-back MMC-HVDC grid-connected simulation model of permanent magnet direct-drive wind power system is built to monitor the quality of DC voltage and AC current at the common connection point, and the influence of PI parameters on grid-connected stability is analyzed. Then, for the key PI controller, a structure combining quasi-proportional resonance （QPR） and nonlinear active disturbance rejection control （NLADRC） is proposed, and the multi-objective improved egret optimization algorithm （MOISBOA） is used to optimize the parameters. Finally, the effectiveness of the proposed controller is verified by establishing the system impedance model.
