This paper presents the development of sequence impedance models for modular multilevel converters (MMC). The intended applications of the models include stability and resonance analysis of high-voltage dc transmission, static synchronous compensation, and other systems that use MMC. The basis of the modeling method is harmonic linearization that has been applied to other types of converters, but...
The advantages of the Modular Multilevel Converter (MMC) as a Voltage Source Converter (VSC) is well known. These includes scalability, increased reliability, lower Total Harmonic Distortion (THD) in output variables, fault tolerance and so forth. The MMC has found its most application in High Voltage DC (HVDC) systems again because of the stated advantages. In the analysis of such systems, because...
This paper presents impedance modeling of modular multilevel converters (MMC) for stability and resonance analysis of HVDC transmission, renewable energy, STATCOM and other systems that increasingly rely on MMC as the hardware building block. The basis of the modeling method is harmonic linearization, which has been applied to other types of converters and converter systems, but a new formulation...
