电网电压不平衡下MMC-SST反馈线性化滑模控制策略
Feedback Linearization Sliding-Mode Control Strategy for MMC-SST Under Unbalanced Power Grid Voltage
摘要
Abstract
When the modular multilevel converter(MMC)is put into the solid state transformer(SST)system,the proportional integral derivative(PID)control method is usually selected.However,this strategy has the disadvantages of complex parameters selection and poor dynamic performance.In order to improve the dynamic performance of the system and simplify parameter selec-tion,a feedback linearized sliding-mode control strategy for MMC-SST system is proposed.Firstly,the overall simulation model of MMC-SST is established.Then,a MMC-SST control model using feedback linearization sliding-mode control is established.Finally,the proposed control method is compared with the conventional PID control strategy through simulation using MATLAB/Simulink platform,verifying that the proposed feedback linearization sliding-mode control strategy has the advantages of easy parameter selection and excellent dynamic performance.关键词
