“…Some of the proposed control strategies have been implemented in dqo rotating reference frame such as Tu et al (2011) and Bergna et al (2012). Nonetheless, it seems to be getting clear that there are significant disadvantages in applying dqo-based control schemes for the control of the MMC differential currents since they do not facilitate complete phase-independent control of the converter state variables, hence the MMC potential will not be fully exploited (Bergna et al, 2013). To overcome this drawback it is necessary to formulate the control problem in the abc frame-in which the MMC is controlled independently per phase-resulting in a tracking problem instead of a regulation one.…”

“…In view of its complicated topology and operating regimes, controlling the MMC is no simple task. In particular, to exploit the full potential of the MMC it seems to be necessary to develop control strategies for the system operating in the rotating (abc) frame (Bergna et al, 2013), this is contrast with the classical strategies developed in fixed dq0 ( ) frames (Tu, Xu, & Xu, 2011;Bergna et al, 2012). This situation leads to a tracking problem instead of the typical regulation one.…”

“…The modular multilevel converter (MMC), first proposed by Marquardt [6], has been considered as the converter of choice for HVDC systems [7] and is already commercially used in HVDC projects [8][9][10]. In comparison with other topologies, MMC offers high modularity and scalability, transformerless operation, reduction of switching power losses and lower output filtering requirements [5,11].…”

A Comparison of Modulation Techniques for Modular Multilevel Converters

et al. 2016

This work presents a comparison of three different modulation techniques applied to modular multilevel converters (MMCs). The three modulation strategies studied in this paper are the phase-shifted sinusoidal pulse width modulation (PS-SPWM), the space-vector modulation (SVM) and the nearest level modulation (NLM). This paper focuses on analysing the particularities and implementation of each modulation technique. The modulation technique largely defines the generated harmonic content, making this is a key point that must be studied in depth. The paper briefly describes the three modulation techniques and analyses the harmonics generated by each one of the methods. In addition, the paper presents and compares the digital implementation of the three modulation methods in a Field Programmable Gate Array (FPGA). The proposed approaches are validated using a real processing platform and experimentally evaluated in a real high-power six-level MMC.

“…The idea of modular multilevel converters (MMC) was first introduced in 2003 [1]. As a new member in MMCC family, MMC is also suitable for high voltage dc current (HVDC) transmission system [2] [3]. In other applications such as photovoltaic or wind turbine generator [4] [5] and motor drive [6], extensive research work has been done on various aspects such as circulating current, modulation method, capacitor voltage balancing, grid voltage distortion, etc.…”

A novel capacitor voltage control strategy for three-phase distribution static synchronous compensators (DSTATCOM) based on modular multilevel converters (MMC) is proposed in this paper. Firstly, modeling of circular interaction among the electrical quantities for MMC-STATCOM is established. And the improved capacitor voltage control structure consists of three loops, a) total active power control loop for the entire apparatus, b) the arm capacitor voltage balancing control loop for each phase and c) individual capacitor voltage balancing control loop in each arm. The output of total active power control is added to the current tracking control as active current reference. The arm capacitor voltage balancing control is critical for the stable operation of the MMC-DSTATCOM, especially in capacitive var compensation mode. A set of cosine functions instead of the output currents is proposed for the individual capacitor voltage balancing control in this paper. Since output current measurement is avoided in the individual capacitor voltage balancing control, the number of current sensors and data communication resources are reduced, especially for practical applications based on MMC with a large number of modules. The effectiveness of the above capacitor voltage three-loop control architecture is verified completely by detailed analysis and experimental results from a MMC-DSTATCOM laboratory prototype with multi-DSP controller system.
