Active Power and Current Control for a Modular Multilevel Converter (mmc) Based System
نویسنده
چکیده
Abstract Modular Multilevel Converter (MMC) has found very wide application in renewable energy sources, DC power transmission, high voltage applications and micro grid. However the technical challenge of MMC is to maintain constant current, constant power and constant voltage at the output depending on the requirement. In this paper a control loop is developed for maintaining constant power at the MMC. The power controller is realized by using PI controller. The PWM technique used for generation of gating pulses is Phase Disposition PWM (PD-PWM) technique, The simulation of current and the active power controller is carried out by MATLAB/SIMULINK and the results are presented.

A Direct Power Feeding System for AC Railway Networks Using Modular Multilevel Converter
Abstract Traditional railway power supply systems impose substantial power quality problems (PQ) on the utility network, such as unbalance, harmonics and a large amount of reactive power. This paper proposes a topology based on three-phase to single-phase modular multilevel converters (MMC) to obviate these problems. The MMC based traction substations (TSS) are connected directly to the utili...
