Abstract This paper investigates an Euler-Lagrange model based passive control for modular multilevel converters based HVDC(MMC-HVDC) system. The topology and operation principle of MMC are introduced first, and for the purpose of balancing the sub-module(SM) capacitor voltages, an improved capacitor voltage values based raking method is proposed which depends on two different maintaining factors that can significantly reduce the averaging switching frequency. Then based on the Euler-Lagrange(EL) mathematical model in synchronous d-q coordinates and its passivity, the passive control with expected state balance points, states and state errors is proposed by damp injection. The proposed control algorithm can realize the decoupled control of real and reactive power, and maintain very good static and dynamic performances. Finally 21-level MMC-HVDC model in electromagnetic transient(EMT) simulation program PSCAD/EMTDC shows the effectiveness and correctness of all the proposed control methods.

Key words： Modular multilevel converter(MMC) sub modules capacitance voltage balancing Euler-Lagrange(EL) mathematical model passive control
