Nikolai I VoropaiN.I. Voropai was a renowned expert in the field of energy systems research. He was an author, and co-author of more than 700 published research contributions. He identified and investigated the fundamental features of complex extended electric power ystems. This allowed explaining multiple phenomena and processes, such as system accidents, based on clear physical representations and developing theoretical foundations for the analysis and synthesis of structurally heterogeneous power interconnections. These achievements laid off the methodological backbone of research efforts by a school of thought that still leads its field to this day. He successfully supervised over 20 PhD students.
