| Research Abstract |
The aim of this research is to establish the core technology of the next-generation environment-friendly battery energy storage system that is characterized by combing the latest Li-ion battery modules with a modular multilevel cascade converter. The three-phase experimental system rated at 200 V, 10 kW, and 20 kWh was designed, constructed, and tested to confirm and justify the operating principles and stable performance of the battery energy storage system. As a result, a total harmonic distortion (THD) value of the line (supply) current complies completely with the Japanese harmonic guidelines. In addition, stable ride-through capability of the so-called “voltage sag” was confirmed by computer simulation under various voltage sag conditions.
