Abstract

Renewable energy is being spotlighted as the electric power generating source for the next generation. Due to an increase inrenewable energy systems in the grid system, their impact on the grid has become non-negligible. Thus, many countries in the world,including Europe, present their own grid codes for grid power conversion devices. In order to experiment with these grid codes, gridfault test equipment is required. This paper proposes both equipment and a control method, which are constructed with a 7-levelcascaded H-bridge converter, that are capable of generating various grid faults. In addition, the Pulse Width Modulation (PWM)method for multilevel converters is compared and analyzed. The proposed structure, the control method, and the PWM method areverified through simulation and experimental results.
