The control method comprises: calculating an actual capacitor voltage and a reference capacitor voltage of the sub-module; dividing the plurality of sub-modules into a plurality of modules, wherein reference capacitor voltages of the sub-modules in the same module are the same, and reference capacitor voltages of the sub-modules among different modules are different; obtaining a first voltage sequence and a second voltage sequence; and determining the sub-modules to be switched on or switched off according to charging and discharging states of the sub-modules, the first voltage sequence and the second voltage sequence, until an actual level of the bridge arm is consistent with a desired level, wherein the desired level changes taking an insert value selected from a combination of one or more elements in a collection {INTERk} as a step."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control method and control system for modular multilevel converter and power transmission system","description":"Disclosed are a control method and control system for a modular multilevel converter and a power transmission system.
