Systems are being developed for power distribution on future navy ships to effectively incorporate advanced electrical systems requiring DC power. These islanded DC microgrids provide new challenges to the management of power flow throughout the system, and thus require advanced controls to accurately regulate and stabilise the systems during changing operational conditions. Therefore, adaptive droop control is proposed as a power management layer for these maritime DC microgrids. This paper reports on a method that uses adaptation of the controller parameters to account for uncertainty and changes in the system in order to accurately regulate the power sharing among distributed generation sources and to stabilise the bus voltage of the system. The proposed method is applied to a virtual prototype of a medium voltage direct current (MVDC) ship power system and demonstrated through notional operational scenarios to test the effectiveness of the control algorithm utilising controller hardware in the loop (CHIL) experimentation.

正在开发用于未来海军舰艇配电的系统，以有效整合需要直流电源的先进电气系统。这些孤岛直流微电网对整个系统的潮流管理提出了新的挑战，因此需要先进的控制来在不断变化的运行条件下准确调节和稳定系统。因此，提出了自适应下垂控制作为这些海上直流微电网的电源管理层。本文报告了一种方法，该方法使用控制器参数的自适应来解决系统中的不确定性和变化，从而准确地调节分布式电源之间的功率共享并稳定系统的母线电压。
