“…Control structure plays a prominent role in reliable operation of the SPS, while there are a great number of vital imposing PPLs. Some of the loads are intermittent, operating on time scales down to milliseconds or less, and can range in power from small kW to vast MW which may reach 90% of the installed power capacity in a short period [12]. By employing a complex Clarke transformation, eight (2 3 ) switching configurations, in αβ frame, are achieved.…”

This paper proposes a new modified model predictive control to compensate for voltage and frequency deviations with higher bandwidth for an AC shipboard microgrid. The shipboard power system (SPS) and islanded microgrids (MGs) have a reasonable analogy regarding supplying loads with local generations. However, a great number of vital imposing pulse loads and highly dynamic large propulsion loads in the SPS make the frequency and voltage regulation a complicated issue. Conventional linear control methods suffer from high sensitivity to parameter variations and slow transient response, which make big oscillations in the frequency and voltage of the SPS. This paper addresses the problem by proposing a novel finite control set model predictive control to compensate for primary frequency and voltage deviations with higher bandwidth and order of magnitude faster than state of the art. Furthermore, a single input interval type-2 fuzzy logic controller (SI-IT2-FLC) is applied in secondary level to damp the steady-state deviations with higher bandwidth. Finally, hardware-in-the-loop (HiL) experimental results prove the applicability of the proposed control structure.

A thorough overview of technical cross-fertilization between terrestrial microgrids and ship power systems is presented in [27]. Some of the main differences between a shipboard micrigrid and larger terrestrial (commercial) grids are summarized in the following [20], [27]:…”

Abstract-The evolution of the use of electricity in marine vessels is presented and discussed in this article in an historical perspective. The historical account starts with its first commercial use in the form of light bulbs on the SS Columbia in 1880 for illumination, going forward through use in hybrid propulsion systems with steam turbines and diesel engines and then transitioning to the present with the first fully electric marine vessel based entirely on the use of batteries in 2015. Electricity use is discussed not only in the light of its many benefits but also of the challenges introduced after the emergence of the marine vessel electrical power system. The impact of new conversion technologies like power electronics, battery energy storage, and the DC power system on overall energy efficiency, power quality, and emission level is discussed thoroughly. The article guides the reader through this development, the present and future challenges by calling attention to the future research needs and the need to revisit standards that relate to power quality, safety, integrity, and stability of the marine vessel power system, which are strongly impacted by the way electricity is used in the marine vessel.

High power motor loads are widely used in shipboard microgrids (SMGs) consuming about 70% of generated electrical power. Voltage dips, which are usually caused by the starting current of high power motors, are one of the main causes of onboard sensitive electrical equipment dropout. This phenomenon must be considered in design of SMGs to comply with maritime standards. In this paper, an evaluation method is proposed to estimate the expected severity of voltage dips and also generator current transient surges due to the onboard motor start-ups under real seagoing conditions. This is based on the Riemannsummation-principle evaluation method. The quasibalanced and unbalanced AC bus voltage cases were carefully selected to present the actual impact of the voltage dips in real SMG. The evaluations are validated by measurements gathered from the ballast pump motor start-up in the SMG. The proposed method can provide ship engineers with necessary information about the actual magnitude/depth of voltage dips. Accordingly, the allowable capacities of high power motors can be estimated, which is beneficial to determine proper motor starter designs and improve the power quality in real SMGs.
