Summary The modular multilevel converters (MMCs) are frequently preferred for medium and high power energy conversion systems thanks to their modular structure and high quality output waveform. The remarkable studies related to the MMC have been carried out in recent years, which are mainly focused on its topology, control, or application. In this paper, MMC circuit topologies consisting of traditional submodule cells and new proposed configurations are introduced, and their control process, modulation techniques, and application areas are discussed in order to provide the readers the current state of the art of MMC technology. A wide part of this article is devoted to demonstrate the recent contributions arising in MMC studies. In this context, this paper not only outlines the circuit topology, control objectives, and applications of the MMC but also presents a comprehensive review, principally in terms of the latest developments of it. Ultimately, detailed proposals and new possible topics are provided to drive future expectations of MMC technology.

“…Despite the high frequency of the final waveform, the switching frequency of each module can be low, resulting in reduced switching losses, since the number of switching devices is large and each of them does not have to operate frequently. In general, MMC systems present easy scalability, leading to high power ratings, and high modularity, allowing more flexible and economical solutions for the transmission systems [2,4,9,10,38,43,44].…”

Voltage Source Converter (VSC) High Voltage Direct Current (HVDC) connection has become a new trend for long distance offshore wind power transmission. It has been confirmed by a lot of research that the maximum distance of a High Voltage Alternative Current (HVAC) sub-marine cable transmission system is limited due to surplus charging current of the cables. The VSC HVDC transmission system has the ability to overcome the limitation and offers other advantages over the HVAC transmission system. This paper is to review the VSC HVDC transmission technology and its application for offshore wind power integration. Firstly, the main components, configuration and topology of the VSC HVDC transmission system are described.Secondly, the converter control system and control strategies are presented. Following that, the capabilities of the VSC HVDC technology are described. Finally, the focus is given on the control methods of the VSC HVDC transmission system for fulfilling grid code requirements concerning Low Voltage Ride-Through (LVRT) and frequency regulation.

“…There also exists a common DC-link in the MMC topology which is unavailable in CHB topology [6]. Based on this consideration, MMCs can be utilized as AC/DC interlinking converters in medium-and high-voltage renewable energy generation systems, e.g., offshore wind farm generation systems [7] and microgrids [8], as shown in Figure 1.…”

A modular multilevel converter with an integrated battery energy storage system (MMC-BESS) has been proposed for high-voltage applications for large-scale renewable energy resources. As capacitor voltage balance is key to the normal operation of the system, the conventional control strategy for the MMC can be significantly simplified by controlling the individual capacitor voltage through a battery side converter in the MMC-BESS. However, the control strategy of the MMC-BESS under rectifier mode operation has not yet been addressed, where the conventional control strategy cannot be directly employed due to the additional power flow of batteries. For this defect, the rectifier mode operation of the MMC-BESS based on a battery side capacitor voltage control was analyzed in this paper, proposing a control strategy for this application scenario according to the equivalent circuit of MMC-BESS, avoiding passive impact on the state-of-charge (SOC) equalization of batteries. Furthermore, the implementation of a battery side converter control is proposed by simplifying the capacitor voltage filter scheme within phase arm, which enhances its performance and facilitates the realization of control strategy. Finally, simulation and experimental results validate the feasibility and effectiveness of the proposed control strategy.is proposed by combining the MMC and BESS together [9]. The extra power conversion system (PCS) of BESS can be saved by this combination. In this paper, this topology is abbreviated as the MMC-BESS. The integration was implemented by inserting battery cells into each submodule (SM) of MMC directly or through a DC/DC interface [10,11]. Due to this distributed integration mode of BESS, the state-of-charge (SOC) equalization of each battery was facilitated, improving the effective utilization rate of BESS compared with the centralized scheme at the DC-link of MMC [12].
