Multi‐objective optimisation of hydroelectric PMSG considering water‐level variation

“…Hydropower generation is recognised as natural resources that is suitable for regional distributed power without environmental pollution, and fits the natural local conditions [1, 2]. Generally, the use of induction generators is the mainstream of hydro‐applications [3–6], however, the amount of inductive reactive power for magnetisation is huge and is often compensated with capacitor banks in parallel [3, 4].…”

“…Generally, the use of induction generators is the mainstream of hydro‐applications [3–6], however, the amount of inductive reactive power for magnetisation is huge and is often compensated with capacitor banks in parallel [3, 4]. An alternative design with PM generators has been discussed recently [2], it showed that a smaller machine with increased efficiency is possible and there is no capacitive compensation is needed in the case.…”

“…However, in the literatures, typically, have some inherent technical difficulties used in hydro applications, it is hard to balance the performances of stability, efficiency, and cost. The permanent magnet synchronous generator (PMSG) is an effective way to solve the above problems, and there are many scholars have focused on this solution [2, 10, 11].…”
