Model complexity may have a significant impact on transient stability results of mixed AC/DC systems. The dynamics of various mixed AC/DC models with a focus on different generator orders and multi-level modular converter (MMC) VSC-HVDC model types is investigated within this paper. MMC VSC-HVDC converter models are based on average value model (AVM) and simplified AVM, while 2 nd , 3 rd and 6 th order generator models are formulated within the research. The paper also considers the impact of inner current control bandwidth. Based on the simulation result, substantial change over the transient stability result is seen with respect to different types of modelling complexity used within the research.

“…The published literature mainly relates to their applications to high-voltage DC (HVDC) transmission [16][17][18], MV electric drives [19][20][21], and STATCOMs [22,23]. MMCs used in BESSs for interfacing low-or medium-voltage batteries to mediumor high-voltage grids were reported in [24][25][26][27].…”

Energy storage systems with multilevel converters play an important role in modern electric power systems with large-scale renewable energy integration. This paper proposes a reverse-blocking modular multilevel converter for a battery energy storage system (RB-MMC-BESS). Besides integrating distributed low-voltage batteries to medium or high voltage grids, with the inherited advantages of traditional MMCs, the RB-MMC-BESS also provides improved DC fault handling capability. This paper analyzes such a new converter configuration and its operating principles. Control algorithms are developed for AC side power control and the balancing of battery state of charge. The blocking mechanism to manage a DC pole-topole fault analyzed in depth. Comprehensive simulation results validate both the feasibility of the RB-MMC-BESS topology and the effectiveness of the control and fault handling strategies.

“…A number of recent publications have adopted the same modeling approach for the MMC as for the two or three-level VSC, though with small modifications. However, these models are either based on strong assumptions regarding the way the MMC control is implemented [3], [4] or they introduce supplementary functions and resort to parameter identification techniques to reproduce its dynamic behavior [5]. Moreover, this type of modeling may not be fully satisfactory since it tends to neglect the significant structural differences between both topologies.…”

Abstract-This paper focuses on simplified models of the Modular Multilevel Converter suitable for large-scale dynamic studies, in particular simulations under the phasor approximation. Compared to the existing literature, this paper does not a priori adopt the modeling approach followed for the original twolevel or three-level Voltage Source Converter. On the contrary, a model is derived following a physical analysis that preserves its average internal dynamic behavior. An equivalent control structure is proposed and various alternatives are highlighted. The proposed model with its controllers has been implemented in a phasor simulation software and its response has been validated against a detailed Electromagnetic Transient model. Finally, an illustrative example is presented with the application of the proposed model on a large grid consisting of AC areas interconnected with a multi-terminal DC grid.
