About This Special Issue
The capacity is a difficult point for unified power flow controller (UPFC) in practical engineering. In order to get higher capacity, modular multilevel converter (MMC) is introduced to UPFC to take the place of traditional three-phase full bridge. The novel power converter topology MMC has been intensively researched and developed during the last years, triggered by features like high modularity, low expense of filters, simple scalability and redundancy. This converter is composed by identical power cells connected in series, each one build up with standard components, enabling the connection to high voltage poles. Although the MMC-UPFC and derived topologies offer several advantages they also introduce a more complex design of the power circuit and control goals, which have been the main reason for the recent and ongoing research.

Aims and Scope:

1. Power topologies of MMC-UPFC
2. Modeling and analysis of MMC-UPFC
3. Modulation and control of MMC-UPFC
4. Circulating current analysis and issues
5. Capacitor voltage balancing methods
6. Design considerations for power and control stages
7. Fault tolerant operation
8. Applications in industry and energy systems
