“…Besides, ESS states, such as state of charge (SoC), can be regulated at this control level. In the tertiary level control, an EMS considering system constraints is designed to achieve specific optimization objectives [31], [32]. The generated optimized commands, including the generator and ESS ON/OFF states, their power setpoints, and voltage references for both generator and ESS sides' controllers, are sent to the lower control levels.…”

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.

“…In [286] is proposed a hybrid energy storage system based on a battery and a superconducting magnetic energy storage element in order to improve the stability of dc power systems of fully electric ships, being used a two quadrant buck-boost dc-dc converter for the battery and an asymmetrical h-bridge dc-dc converter for the superconducting magnetic energy storage element. In [287] is presented a conventional structure of an on-board ship power system (Figure 34), having been studied the power flow in the electric power system with energy storage and energy management systems, comprising ac, dc and hybrid ac-dc power grid architectures.…”

Concerns about greenhouse gas emissions are a key topic addressed by modern societies worldwide. As a contribution to mitigate such effects caused by the transportation sector, the full adoption of electric mobility is increasingly being seen as the main alternative to conventional internal combustion engine (ICE) vehicles, which is supported by positive industry indicators, despite some identified hurdles. For such objective, power electronics technologies play an essential role and can be contextualized in different purposes to support the full adoption of electric mobility, including on-board and off-board battery charging systems, inductive wireless charging systems, unified traction and charging systems, new topologies with innovative operation modes for supporting the electrical power grid, and innovative solutions for electrified railways. Embracing all of these aspects, this paper presents a review on power electronics technologies for electric mobility where some of the main technologies and power electronics topologies are presented and explained. In order to address a broad scope of technologies, this paper covers road vehicles, lightweight vehicles and railway vehicles, among other electric vehicles.

“…In addition to the exploration and research of new energy sources, the improvement of the energy supply form is also of equal significance (Zhao et al, 2022a). The role of the regional integrated energy system, as a promising solution of bearing energy for human society in the future, is rapidly developing in the field of efficient energy utilization, energy conservation, renewable energy consumption, and emission reduction (Balsamo et al, 2020). Followed by the foundation of the RIES concept, countries worldwide have responded positively and vigorously by carrying out extensive research on the RIES (Zhang et al, 2022).…”

For a regional integrated energy system (RIES) composed of an energy supply network and distributed energy station, the uncertainty of distributed photovoltaic (PV) output and the fluctuation of various loads pose significant challenges to the stability of system operation and the accuracy of optimal scheduling. In order to enhance the operational reliability of regional integrated energy systems and reduce the impact of photovoltaic and load uncertainties on distributed energy stations, this study proposes robust optimization method of regional integrated energy systems that takes into account the uncertainty of the distributed energy station. First, the regional integrated energy system is divided into an upper electric-gas energy supply network and a lower distributed energy station. The upper model mainly realizes energy transmission, while the lower model is a two-stage robust optimization model of distributed energy stations in the form of min–max–min, which mainly realizes flexible energy supply of different types of energy. Then, the lower two-stage robust optimization model is simplified and solved using a column and constraint generation (CCG) algorithm. After that, an alternating direction method of multipliers (ADMM) is used to solve the upper and lower models of the regional integrated energy system, and the solution scale is reduced while ensuring the correlation between the energy transmission network and the distributed energy stations. Finally, a test example is provided to illustrate the effectiveness and usefulness of the proposed method. It follows from simulation results that the robust optimization method can effectively reduce the instability of the system operation caused by uncertainty factors and improve the system’s anti-interference ability, and in addition, systems with high penetration levels of photovoltaic output will benefit more from robust optimization.
