Review on the application and research progress of photovoltaics-ship power system

Facing with the problems of energy-saving emission reduction and marine pollution, the shipping industry have invested a great interest in developing “Green Ship” by utilizing the solar energy technologies. Solar ship, which integrates the solar photovoltaic (PV) system into its own ship power system, is becoming one kind of most promising and fastest developing green ship. In this paper, the development trend of solar ship is stated. For the solar PV system that integrated in ship power system, two different kinds of operation mode are analyzed, including off-grid and grid connected mode. In order to optimize energy managements of photovoltaic-ship power system (PSPS), the operation control strategy of multiple inverter equipment under grid-connected mode are studied. Moreover, the points of focus, methodology and original conclusion are detailed to explain the recent theoretical research progress.
