Peng, H.; Gao, R.; Song, X., and Shen, Q., 2018. An automatic decentralized control method for low voltage power for ship's shore power. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 851–855. Coconut Creek (Florida), ISSN 0749-0208. Current electrical control methods of ship's shore power can not disperse the electrical distribution and have the problems of poor transport stability, low electrical utilization and long time of electrical transmission. Based on the condition of ship's shore power with low voltage, an automatic decentralized control method is proposed. By determining the maximum and minimum of the required electrical value, it can disperse the electrical accurately, reduce the time of electrical transmission, and improve the electrical utilization. Each closed loop system in the ship's shore power is controlled, to make the index to stabilization, and improve the stability of electrical dispersion. The experimental results show that the method has high dispersive stability, high electrical utilization and short electrical transmission time.
