The proposed methodology is based on analysis of the configuration and load of the system under consideration, taking into account the system’s operation modes, while excluding the modes in which the ship is supplied via shore grid. The authors experimentally examined and analysed the electric and hybrid modes using data collected from sea trials results of the passenger-car ferry. Finally, an overall assessment of power quality in the considered power system is presented. %@ 2083-6473 %R 10.12716/1001.19.04.29
