Hybrid MMC (Hy-MMC) has broad application prospects because of the negative level
output ability in its bridge arm. A Hy-MMC topology with high-modulation ratio is designed in …

The bus voltage level on each bus in the distribution system (DS) is greatly influenced by the
presence of reactive power (Q). Under voltage conditions can occur if the system lacks a Q …

There have been multiple attempts to improve the submodule (SM) structure, the
fundamental block in Modular Multilevel Converter (MMC). The focus has been mainly on …

In the era of growing awareness and concern for environmental changes, power-electronic
engineers are leading the transition away from fossil fuels to renewable energy sources. In …

The battery packs experience alternate current in the modular multilevel converter battery
energy storage system (MMC-BESS), which can cause additional charge throughput and …

Within modern power systems, conventional synchronous generation (powered by fossil
