“…In some cases, advanced algorithms are used to achieve reconfiguration objectives. Common reconfiguration objectives in the literature include the system loss minimization [115], delivery power maximum [116], preserving the stability margin [117], and load service quality maximum [118]. In addition, there are some approaches to ensure power continuity during the interruption, such as providing battery supplied power to critical loads, and implementing ride-through on downstream inverter-fed motors.…”

This paper presents a review of coordinated control strategies, stability analysis, and fault management for DC shipboard microgrids (DC-SMGs). As an emerging application, the DC-SMG lacks a comprehensive summary of the control schemes. Considering the specific load profile in ships, this paper discusses the coordinated control strategies of diesel generators and energy storage system (ESS). Depending on the maritime conditions, different operation modes are switched by the energy management system (EMS). Due to the presence of highbandwidth controlled constant power load (CPL) converters, negative impedance instability is induced. Meanwhile, the pulsed loads in DC-SMG may affect the voltage stability significantly. Small-signal and large-signal stability analysis can be used to evaluate the effect of these two types of loads. In the aspect of shipboard protection system, this paper presents the specific requirements of DC-SMG based on the standards. Lacking of 'ground' in ships, solutions in designing the grounding system for DC-SMG is described. Besides, the short-circuit fault management consisting of fault detection, fault isolation, and reconfiguration in DC-SMGs are summarized. Finally, existing commercial DC ships are presented and compared to demonstrate the developing trends.

Fault management study in smart grid systems (SGSs) is important to ensure the stability of the system. Also, it is important to know the major types of power failures for the effective operation of the SGS. This paper reviews diverse types of faults that might appear in the SGS and gives a survey about the impact of renewable energy resources (RERs) on the behavior of the system. Moreover, this paper offers different fault detection and localization techniques that can be used for SGSs. Furthermore, a potential fault management case study is proposed in this paper. The SGS model in this paper is investigated using both of the Matlab/Simulink and the Real Time Digital Simulation (RTDS) to compute the fault management study. Simulation results show the fast response to a power failure in the system which improves the stability of the SGS.
