Abstract

The Modular Multilevel Converter (MMC) with full bridge cells is available for a utility interactive inverter in high voltage line. When it is interconnected with power line, it is possible to control the active power flow in order to supply or charge the power in the line. This research applied a Hexagonal MMC to 3-phase AC-AC conversion system. The system is controlled by internal model principle and MMC can operate reliably. Theory of the power flow control of MMC and effectiveness of the proposed control method in the simulation are presented.
