“…The research on stability caused by pulsed loads is limited in existing literature and is highly needed. Most of existing works focus on providing solutions in mitigating the impact of pulsed loads by providing a high power ramp [16], [17], [18]. This paper will present current studies on instability issues caused by pulsed loads.…”

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.

“…10,11 That means it can inject both active and reactive power instantaneously into the grid to achieve a highquality power flow in the system. 13,14 Though, several energy storing devices have been in the limelight in recent years. Today, only two types of direct electrical energy storage system are available in the market: SMES and Super-Capacitor Energy Storage (SCES) system.…”

The electrical grid with pulsed power loads (PPLs) is of the significant interest in aerospace and marine applications. In this work, a Superconducting Magnetic Energy Storage (SMES)-based Power Conditioning System (PCS) is proposed to compensate the pulsating load, and mitigates the adverse consequences of the load. A uniform source current and power with minimum variations is maintained irrespective of the PPL. A detrimental high rating stress on the system due to the load is substantially reduced by the proposed system. Particularly, this paper presents a nonlinear control approach based on Dynamic Evolution Control (DEC) for tight error regulation of the controlling parameters (three-phase compensating currents and DC-link voltage). The control scheme is implemented in both the inverter and DC-DC converter of the PCS for an efficient energy exchange between the SMES coil and the grid. Moreover, a comparative performance of the control scheme is examined under two different modes of operation, that is, Shunt Active Power Filter (SAPF) and SMES-based PCS mode. The proposed system is validated in MATLAB/Simulink and real-timed SPACE1104 environment.dynamic evolution control technique, power quality, pulsed power load, shunt active power filter, superconducting magnetic energy storage, system stability List of Symbols and Abbreviations: X, System rating (in kVA); T, Time period for each cycle; n, Number of cycles; ω, Angular frequency; V dc , DC-link voltage across Cdc; L c , Interfacing inductance; L smes , Equivalent inductance of SMES coil; I smes , SMES coil current; m, Design parameter of DEC (rate of evolution); ξ, A positive co-efficient (range: 0 to 1); α, Duty cycle of DC-DC converter; I sd , Fundamental d-axis component of nominal load current (i.e., during NL condition only); v a , v b , v c , Measured three-phase voltages at the PCC; i sa , i sb , i sc , Measured three-phase source currents; i La , i Lb , i Lc , Sensed three-phase load currents; i ca , i cb , i cc , Sensed three-phase compensating currents; v Ld , v Lq , Transformed d -q components of v a , v b , v c ; i cd , i cq , Transformed d -q components of i ca , i cb , i cc ; i Ld , i Lq , Transformed d-q components of i La , i Lb , i Lc ; d nd , d nq , Switching state functions in d -q frame; d na , d nb , d nc , Switching state functions in a -b -c frame;
