Autor: Seok‐Won Jung, Dohyun Kang, Kumarasamy Palanimuthu, Young Hoon Joo, Sang‐Yong Jung

Publikováno v: Wind Energy, Vol 27, Iss 9, Pp 847-872 (2024)

Abstract This study introduces a constrained many‐objective optimization approach for the optimal design of 20 MW direct drive (DD) permanent magnet synchronous generators (PMSGs). Designing a high‐performance, competitive DD‐PMSG requires cons
