Abstract
An energy storage MMC topology is proposed to avoid the microcirculation of battery. The topology consists of six bridge arms in three stages and can be connected to DC system and AC system. Each bridge arm is composed of one bridge arm inductance and N energy storage sub-modules with the same structure in series. The energy storage sub-modules include a half-bridge power module, a battery energy storage module and a group of anti-parallel thyristors. The group of anti-parallel thyristors is connected in series over the DC cable between the battery energy storage module and a capacitor of the half-bridge power module. The switching control is performed on the battery in the energy storage MMC according to the systematic operating mode.
