“…In terms of port construction, the electrification of marine transportation represented by shore power technology, electric propulsion ships (Sun et al, 2022), and electric-driven port machinery and the zero-carbon fuel technology represented by hydrogen energy/ammonia energy (Wang et al, 2021b) have promoted the deep integration of ports and multi-type energy networks, and a special "marine energy-integrated transportation system" has been initially formed. At the same time, the popularity of multi-modal transport and rapid development of the cold chain transport have brought diversified comprehensive energy demand to the port.…”

Introduction: The structure of green and low-carbon ports is complex, and an integrated port energy system with complex characteristics such as multi-energy flow coupling and information physical fusion has been formed.Methods: Digital twin technology provides a new solution for the perception, analysis, and optimization of integrated port energy system. The paper explores the digital twin of integrated port energy system. Based on the development trend and function of integrated port energy system, the digital twin of integrated port energy system architecture is proposed to explore its potential application services. Specifically, considering the functions and structural characteristics of the port, the digital space of integrated port energy system is established, which describes the pan electrification, multi energy flow fusion, the “physics-information-value” coupling, and the characteristics of system operation under uncertain scenarios of integrated port energy system from the physical and data dimensions. The hybrid driving method based on data and mechanism is used to explore digital twin of integrated port energy system and find potential better applications.Results and discussion: Finally, combined with the current development needs of integrated port energy system, this paper analyzes the key problems and technologies that need to be broken through in the specific implementation of digital twin of integrated port energy system, with a view to providing some thoughts and references for the low-carbon development of ports and the future application of digital twin technology under the goal of “double carbon”.

“…D UE to stochastic nature of renewable energy generation(REG) and charging behavior, DC interconnection is advantageous for a REG-integrated power system or EV charging infrastructure as its looser grid code [1]. Part of rectifiers can be saved and merely voltage magnitude is considered in a DC network, indicating higher operation reliability and resilience [2]- [5]. Reduced conversion loss also highlights the necessity of DC system deployment [6].…”

This paper proposes a novel attack identification mechanism for internet-of-things-based (IoT-based) convertercomposed DC grids, where each agent collects its own and neighbours' measurement data for output regulation to meet a preceding power-sharing consensus. Independent from modelfree or average-model-based attack detection theories, this mechanism is mainly inspired by converter stitching behavior analysis. Correspondingly, when facing latent signal substitution or agent instigation attacks, through comparing estimated signals with received ones for signal source authentication, both self-sensors and neighbours will be inspected. Eventually, not only can such attacks be detected, but also will respective attack sources be identified. A simulation case of 4-agent 800V IoT-based DC grid on Simulink and a hardware case of 3-agent 90V IoT-based DC grid on dSpace testing platform were investigated. Experimental results revealed that the estimation ratio error kept lower than 3.9% and all attacks were successfully identified, verifying the effectiveness of the proposed mechanism.

“…A variety of control strategies to regulate the power flow onboard ships in the presence of PPLs has been reported in the past 20 years and in this section we discuss [2] through [13] as relevant examples. Power quality problems arising from high-power pulsed loads are investigated in [2] where the energy stored in the generator and power converter are utilized to reduce voltage sags using a system-level model implemented in Simulink without experimental validation.…”

This paper addresses the new pulsed power load requirements for shipboard power systems introduced in the 2018 revision of the military standard 1399 section 300, part 1. With the number of pulsed loads increasing onboard modern ships, the AC distribution bus is susceptible to voltage and frequency abnormalities due to the limited inertia of the synchronous generators powering the ship. In this paper the strict limits imposed by the military standard 1399 are met with a system-level solution and a novel sizing method for the energy storage system. A targeted control system ensures that the power delivered by the AC bus has smooth transients, within the limits set by the military standard, thus reducing the stress on the shipboard power distribution system and the generators. A novel energy storage system (ESS) sizing algorithm is proposed to identify the minimum number of supercapacitors for a given set of control parameters. The proposed control system is simulated and experimentally validated on a laboratory testbed built with SiC power converters managed by FPGA control boards.
