KRČÁL, V. Analytické metody pro provozní výzvy v mřížových sítích nízkého napětí [online]. Brno: Vysoké učení technické v Brně. Fakulta elektrotechniky a komunikačních technologií. 2025.
Vít Krčál began his PhD studies in 2019. He passed the doctoral state examination in 2021 and submitted his dissertation in October 2025. The dissertation focuses on the operation of low-voltage mesh networks, which are primarily used in large urban distribution systems. Due to their specific configuration, characterised by high meshing, they differ significantly from conventional low-voltage systems and thus present numerous challenges that have not been extensively resolved within current scientific and research knowledge. This was also the reason for the relatively large thematic scope of the work, which addresses a few prioritised areas: issues of high short-circuit current levels, indication of cascading faults, indication of damaged fuse or line interruptions, and settings for active power overflow protection to achieve selective tripping of high-voltage faults. The selection of these areas was made based on demands from distribution system operators and also overlaps with the applied research projects that were being addressed. During his studies, Vít Krčál invested significant effort in developing the dissertation's theoretical and practical components, demonstrating independent scientific capability. As part of his studies, he contributed to teaching exercises in Distribution and Industrial Networks and participated in eight applied research projects funded by the Czech Technology Agency (TAČR), resulting in eight outputs co-authored by Vít Krčál. In the academic year 2021/2022, he spent three months at Aalto University in Finland. Vít Krčál is the author or co-author of 15 international conference papers, 6 national conference papers and 3 articles in an impact-factor journal. There are 15 records in the Scopus database and 2 records in the Web of Science database; his h-index is 1. The candidate meets all prerequisites for the Doctor title. I recommend the dissertation for defence.
