The aim of this research is to investigate load flow of direct current distribution system on trimaran ferry ship. Radial Shipboard Network Structure with Direct Current Distribution Systems has been proposed in this research. Load flow simulation has been done by calculating electrical load calculation based on ship operation. Then, the one-line diagram of direct current distribution system is developed on electric power software. Simulation results show that direct current distribution system has been successfully implemented on hybrid powered trimaran Ship. In sailing conditions, the overall real power requirement is 20,201 MW and the reactive power is 7,757 Mvar. While the power distributed is 20,493 MW of real power and 7.816 Mvar of reactive power. In manoeuvring conditions, the actual power requirements are 21,251 MW and the reactive power is 8,16 Mvar and for power distributed is 21,573 MW of real power and 8,224 Mvar of reactive power. In loading and unloading conditions, the actual power requirements in this operating condition are 0.616 MW and the reactive power is 0.292 Mvar and for power distributed is 0,635 MW of real power and 0,296 Mvar of reactive power. In the condition of entering the port, the required power is 12.906 MW for real power and 4.969 MW for reactive power and for power distributed is 13,027 MW of real power and 4,994 Mvar of reactive power. The result showed that the concept direct current distribution system has been successfully developed in this research to combine diesel generators with marine renewable energy to make sure that the distributed power stay adequate all through operation.
