Comparison of ship power systems from an optimal economic operation point of viewComparison of ship power systems from an optimal economic operation point of view Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-11-182015enFor many years, the predominant concept on board ships was to have separate propulsion and generator engines. However, more recently, the adoption of hybrid installations with shaft generators, is becoming increasingly common. In this paper, a case study is presented where measurements from actual equipment are used to compare the propulsion and power plants of a typical ship to a hybrid one. Also, a new algorithm for electrical load distribution is introduced and examined in this case.http://creativecommons.org/licenses/by/4.0/256 - 260Electric Ship Technologies Symposium IEEE Michalopoulos, P Prousalidis, J.M Tsekouras, G.J Kanellos Fotios Κανελλος Φωτιος Institute of Electrical and Electronics Engineers Lagrange optimization load distribution
