协调功率控制及环流抑制的模块化多电平换流器互联阻尼配置无源控制方法研究
Research on Interconnection and Damping Assignment Passivity-based Control Method for Modular Multilevel Converters to Coordinate Power Control and Circulating Current Suppression
摘要
Abstract
At present,the power transmission and circulating current suppression are separately modelled and controlled by using most of the control technologies for modular multilevel converters ( MMCs ),which can hardly ensure the global stability of the system.In this paper,an interconnection and damping assignment passivity-based control ( IDA-PBC )method with global stability and strong robustness is applied to the design of MMC controller.The mathematical model of MMC and the port-controlled Hamiltonian model are established in two-phase stationary coordinates.Moreover,the expressions and range of control parameters for the IDA-PBC controller are deduced.Different from the other control methods for MMCs,the IDA-PBC controller can control the power transmission and suppress the circulating current at the same time,and it can also obtain the range of control parameters.Therefore,it can comprehensively analyze the stability of the control system.Finally,the feasibility and effectiveness of the proposed control strategy are verified by simulation results.关键词
