Special Issue Information
Dear Colleagues,
With the large-scale integration of renewable energy sources, the power system is gradually becoming dominated by power electronic converters. However, as the proportion of power electronic sources increases, the operating characteristics of the power system undergo fundamental changes. Firstly, the voltage and frequency support capability of the grid-following control technology is weak, leading to the deterioration of power system stability. Grid-forming control technology is regarded as the most promising solution to this issue. In addition, the fault characteristics of converters are different from traditional synchronous generators, resulting in a decrease in the adaptability or even failure of traditional relay protection technology. Thus, there is an urgent requirement to investigate the novel control and protection technologies of converter-based power systems to guarantee the safe and stable operation of power systems.
This Special Issue invites academics, researchers, and professionals to contribute original research papers and reviews that explore key control and protection technologies for converter-based power systems under symmetric and asymmetric conditions. Topics of interest for this Special Issue include, but are not limited to, the following:
- Control technology of grid-forming/grid-following converters;
- Fault ride-through technology of grid-forming/grid-following converters adapted to symmetric and asymmetric faults;
- Small-signal stability analysis of grid-forming/grid-following converters;
- Transient stability analysis and enhancement of grid-forming/grid-following converters;
- Interaction coupling mechanism analysis of multi-converter;
- Fault characteristic analysis of grid-forming/grid-following converters;
- Adaptability analysis of existing protection and performance improvement;
- New protection principles adapted to converter-based power systems;
- Fault diagnosis and location technologies;
- Control and protection coordination techniques;
- Protection technology for DC power grid;
- Application of AI in power system protection;
- Converter-based voltage and frequency control in distribution/microgrid system;
- Hybrid knowledge data-driven optimization and control for new power systems.
