Abstract :
The Modular Multilevel Converter (MMC) with full bridge cells is available for utility interactive inverter in high voltage line. When it is interconnected with power line, it is possible to control the active power flow so as to supply or charge the power in the power line. This research applied the MMC to grid connection system of distributed generator. Theory of the power flow control of the MMC related to control capacitor voltage on arm cells is proposed. And effectiveness of the control method is presented by simulation.
