Cyber-attacks in modular multilevel converters (2022)
Journal Article
Burgos-Mellado, C., Donoso, F., Dragicevic, T., Cardenas-Dobson, R., Wheeler, P., Clare, J. C., & Watson, A. J. (2022). Cyber-attacks in modular multilevel converters. IEEE Transactions on Power Electronics, https://doi.org/10.1109/TPEL.2022.3147466

Distributed control of modular multilevel converter (MMC) submodules offers several potential benefits such as flexibility and modularity. In this approach, low-level control tasks, such as capacitor voltage balancing, can be distributed amongst cont... Read More about Cyber-attacks in modular multilevel converters.

In IECON 2021 - 47th Annual Conference of the IEEE Industrial Electronics Society (1-6). https://doi.org/10.1109/IECON48115.2021.9589971

High Voltage Direct Current (HVDC) grids are becoming a preferred option for the expansion of the traditional electrical networks as a result of their potential economic, technical and environmental benefits. Developing HVDC grids includes the linkin... Read More about Trapezoidal operation of modular multilevel DC-DC converter for HVDC interconnections.

Distributed Predictive Secondary Control for Imbalance Sharing in AC Microgrids (2021)
Journal Article
Navas-Fonseca, A., Burgos-Mellado, C., Gomez, J. S., Donoso, F., Tarisciotti, L., Saez, D., …Sumner, M. (2022). Distributed Predictive Secondary Control for Imbalance Sharing in AC Microgrids. IEEE Transactions on Smart Grid, 13(1), 20-37. https://doi.org/10.1109/TSG.2021.3108677

This paper proposes a distributed predictive secondary control strategy to share imbalance in three-phase, three-wire isolated AC Microgrids. The control is based on a novel approach where the imbalance sharing among distributed generators is control...

Experimental Validation of a Nested Control System to Balance the Cell Capacitor Voltages in Hybrid MMCs (2021)
Journal Article
Donoso, F., Cardenas, R., Espinoza, M., Clare, J., Mora, A., & Watson, A. (2021). Experimental Validation of a Nested Control System to Balance the Cell Capacitor Voltages in Hybrid MMCs. IEEE Access, 9, 21965-21985. https://doi.org/10.1109/ACCESS.2021.3054340

© 2013 IEEE. In a hybrid modular multilevel converter (MMC), capacitor voltage balance between the Full-Bridge Sub-Modules (FBSMs) and Half-Bridge Sub-Modules (HBSMs) is only possible when the arm currents are bipolar. For a grid-connected MMC, opera... Read More about Experimental Validation of a Nested Control System to Balance the Cell Capacitor Voltages in Hybrid MMCs.

Conference Proceeding
Burgos-Mellado, C., Gutierrez, J., Pineda, C., Donoso, F., Watson, A., Sumner, M., …Mora, A. (2020). Distributed Control Strategy Based on a Consensus Algorithm for the Inter-cell and Inter-cluster Voltage Balancing of a Cascaded H-Bridge Based STATCOM. In 2020 IEEE 21st Workshop on Control and Modeling for Power Electronics, COMPEL 2020 (1-8). https://doi.org/10.1109/COMPEL49091.2020.9265758

© 2020 IEEE. Cascaded H-bridge converters are widely used in the implementation of medium voltage static synchronous compensators (STATCOMs). This is because of the advantages of relatively high-power density and the improved utilisation of low-volta...
