As more distributed renewable energy sources are installed in the utility grid, the static synchronous compensators are applied to manage the power factor and the grid voltage in the medium-voltage level of the power system. The cascaded multilevel converter with single-star topology is well applied to this application. The dc-capacitor voltage balancing control is a fundamental issue, and it can...
The modular multilevel cascaded converter with single-star bridge-cell (MMCC-SSBC) is very suitable for next generation high-scale renewable energy resource system for the low switching loss, low output current distortion, and high reliability. The voltage balancing control is an important issue for MMCC-SSBC to maintain system operation which can be accomplished by negative sequence current and/or...
The static synchronous compensator (STATCOM) are installed at the medium-voltage level of power system for grid voltage regulation and power factor improvement. The star-connected cascaded multilevel converter is widely for high voltage and high rated power STATCOM application. The voltage balancing control is a fundamental issue for cascaded converter, which can be implemented by negative sequence...
