Summary: In this article, a new enhanced modular multilevel converter (EMMC) is introduced, which addresses the drawbacks of the conventional modular multilevel converters (MMC). The EMMC, based on a new submodule (SM) structure, is fully modular and requires fewer switches and capacitors. It possesses the features of reduced energy-storage requirement and dc fault-tolerant capability.

Summary: This paper proposes a novel reliability analysis method of bidirectional power-converter (BPC) in battery energy storage systems (BATT-ESSs), considering dynamic and fault scenarios in a DC microgrid. The study shows that the fault-current-based failure rate (FCBFR) of the BPC in BATT-ESSs is larger than the dynamic-voltage-based failure rate (DVBFR). Furthermore, the fault and dynamic scenarios also significantly decrease the component-level and system-level reliability of the BPC.

Summary: This paper focuses on modeling Delta-connected STATCOMs with embedded energy storage devices based on the Modular Multilevel Converter (MMC) technology. A flexible modeling approach is proposed, allowing easy interfacing of various converter models with various energy storage device models. Four commonly used types of MMC models are applied to STATCOM modeling: detailed, detailed equivalent, arm equivalent, and average value. Super-capacitors and batteries are used as energy storage devices, and the dynamic performances of the models are compared in transient simulation cases using EMTP.
