“…The control interfaces for hardware in the loop arrangement using FPGA-based solutions with appropriate communication protocols have been demonstrated. Data points were strategically placed throughout the system for subsequent data analysis [66]. It has been noted that most of the literature on maritime microgrid models has made use of commercially available software such as PSCAD and MATLAB.…”

This paper discusses contemporary problems concerning ship microgrids. It focuses on the role of power electronics and power quality issues, both conventional, such as voltage and frequency variations, and new issues, such as waveform distortions ensuing from the wide proliferation of power electronics in ship microgrids. The paper also contains a discussion on the provisions of the Unified Requirements of International Association of Classification Societies and other leading power quality standards in the industry, with an emphasis on Total Harmonic Distortion (THD) definition. An overview of power converters for high power applications in ships and their impact on ship networks is also given. Next, original results of various power quality phenomena recorded in ship microgrids are presented and commented on, followed by a review and recommendations for maritime microgrid modeling and signal processing methods for power quality assessment in the discussed systems. Finally, preliminary proposals for power quality control are presented.

“…In several power systems' applications (e.g., microgrids [1][2] and vehicular [3][4][5][6]), the DC technology is demonstrating its capability as an enabler for pursuing the sustainable energy goals [7]. While the extensive use of controlled power converters in modern DC systems ensures real-time power and voltage control, it also causes specific issues [8].…”

Advanced DC microgrids design requires considering interdependent aspects. In these flexible grids with large penetration of high-bandwidth controlled converters, both system stability and short circuit limitation are crucial aspects to be attained. The design of filtering stages directly affects both: on one side the stability is beneficially influenced by a large filter capacitor, while on the other the short circuit current increases with oversized capacitors. Thus, voltage stability and filter's short circuit contribution are discordant goals, which need to be carefully balanced by the designer. To solve this issue, a design procedure for sizing the LC filtering stage and the main bus voltage in a cascade-connected DC power system is proposed. The aim is to ensure meeting both voltage/current ripple requirements, as well as accomplishing system stability and limiting the energy supplied into a fault. Final tests on a Hardware-In-the-Loop system and electro-magnetic transients' simulations are used to verify the effectiveness of the filter's designing procedure.
