电网不同运行方式下MMC无源双积分滑模控制策略研究
Research on passive-based control-dual integral sliding-mode control of MMC under different operating modes of power grid
摘要
Abstract
To improve the system control performance and meet the dynamic response of the system by the inner current loop control of the modular multilevel converter(MMC),we propose a passive dual integral sliding mode control(PBC-DISMC)method.Based on the Euler-Lagrange model of MMC,this method applies the passive theory to the inner current control and combines the advantages of dual integral sliding mode control.It uses the hyperbolic tangent function as the saturation function to meet the requirements of smooth switching of sliding mode control and establishes a value function based on the dual integral sliding mode surface and combines the nearest level modulation to perform sliding mode prediction on the MMC sub-module capacitor to obtain the optimal switching control.Matlab/Simulink is employed for simulation verification.Our results show that PBC-DISMC has good anti-interference ability and delivers steady-state performance under different operating modes of the power grid.关键词
