“…Voltage source converter (VSC) based high voltage direct current (HVDC) transmission systems, including multi-terminal HVDC systems, are widely applied to transmit the power [2,3], in which the modular multilevel converter (MMC) topology attracts the most attention of researchers [4]. The MMC topology is also used in DC distribution and power quality control, such as a unified power flow controller (UPFC) and static synchronous compensator (STATCOM) [5,6]. Most research has focused on the operation and control CrossCheck date: 21 December 2018 strategy of MMCs [7][8][9][10][11], while their failure prediction has not received much discussion, although it is an important issue in power systems [12,13].…”

The modular multilevel converter (MMC) is now the most attractive topology for medium and high voltage power conversion applications with several advantages over the traditional voltage source converter (VSC). However, due to a large number of sub-modules (SMs) in the MMC, system reliability is a big challenge in its practical application, where each SM may be considered as a potential point of failure. In this paper, a reliability evaluation based on the Markov model is proposed for the MMC. The failure rates of the power electronic devices and SMs are firstly analyzed. Then, the Markov model and the state transition equation of the system are built in detail. A general reliability evaluation function is established, in which the mean time to failure and reliability evaluation of the MMC with redundant SMs are also discussed. Finally, a practical direct current (DC) distribution example for reliability evaluation is analyzed, and the results verify that the reliability evaluation based on the Markov model could provide a useful reference for project design.

“…Other widespread used controls include proportional integral (PI) control and proportional resonant (PR) control. 26,27 Apart from the steady-state error due to the nature, the controller design is demanding in terms of tuning. Furthermore, because the individuality of the controlled system is not taken into consideration, the compensation result has been unable to meet the accuracy demand.…”

Summary To improve the voltage withstand level and maintain a high effective switching frequency of conventional active power filter, modular multilevel converter (MMC) with a high number of voltage levels is employed in shunt active power filter recent years, but few articles study this topology from the control strategy applicable to various non‐ideal states. This paper proposes a passivity‐based control (PBC) scheme for MMC‐based shunt active power filter (MMC‐SAPF) with independent positive‐ and negative‐sequence components, and the proper control laws have been defined based on the PBC method, which can also be applied to the non‐ideal state. The passivity of MMC‐SAPF and stability analysis are proved, and damping injection idea is used to design corresponding controllers with high dynamic performance. Besides, the overall control scheme is also based on circulation current suppressing controllers, submodule capacitor voltage controllers, and a harmonics detection section that can choose compensation signals flexibly according to the capacity of active power filter and is applicable in non‐ideal states, as well as ideal state, which can improve the comprehensive performance of this system. By comparing PBC with traditional PI control under ideal state and various non‐ideal operating states, the effectiveness and superiority of proposed strategy were validated by simulation and downscaled experiments.
