Hydrogen fuel is a flexible and clean secondary energy source or carrier enabling renewable energy transition. In existing markets, hydrogen is generated from coal, fossil fuels, and natural gas, resulting in brown or grey hydrogen. However, renewable energy sources can improve the color index of hydrogen. This research article presents the optimal and economical operation of a green hydrogen production plant with an electrolyzer, solar photovoltaic (PV), grid connection, renewable Energy Certificates (rECs), and Virtual Battery Ledger (VBL). rECs concept tracks the renewable energy generation from the PV plant. VBL keeps an accounting of rECs creation, expiration, and trading. rECs are expired when used by an electrolyzer or transacted on the block-chain enabled trading platform (e.g., Singapore Power rECs Marketplace). The study demonstrates the possibility of generating green hydrogen with an efficient virtual accounting method and energy management strategy. © 2023 IEEE.

Threat assessment of targets is a critical aspect of situational awareness, and forms the foundation of intelligent command decision-making. By integrating threat factors through grey relational analysis based on target type, speed, position, and other information, this paper studies the quantitative modeling of target capabilities based on multiplex network modeling method. The proposed approach enables to evaluate the threat level of targets based on the degree of capability decay. As thus, the optimal target set can be selected. The effectiveness of the method is verified through simulation examples. © 2024 Asian control Association.

Shipboard transfer alignment is a procedure for determining the initial navigation information of the ship-mounted guided weapon system’s SINS by receiving the surface ship INS information. In order to improve the navigation accuracy of the ship-launched guided missile system, it is necessary to enhance the precision and accuracy of the shipboard transfer alignment. Generally, the shipboard transfer alignment uses both velocity matching and attitude matching to increase observability. Estimating the misalignment error between SINS and MINS using an extended Kalman filter is necessary to obtain the initial attitude of SINS in shipboard transfer alignment to which attitude matching is applied. Because it takes several minutes for the estimated misalignment error to converge, it is essential to reduce the alignment time, especially in the case of weapon systems. This paper presents the possibility of utilizing the shipboard stored transfer alignment for navigation-grade INS mounted on the inclined launching system. There have been no reports of previous studies on the shipboard stored transfer alignment. In a similar research case, a rapid initial alignment method using the pre-performed alignment results was proposed to reduce the alignment time of tactical-grade INS, which was mounted on the launch platform with MINS. To verify the possibility of the shipboard stored transfer alignment, the existing shipboard transfer alignment was repeatedly performed using an inclined guided missile system deployed in the military. The results show that the repeatability and accuracy of the misalignment error satisfy the initial attitude error requirement. Therefore, based on the test results, it is verified that the shipboard stored transfer alignment for the inclined launching guided missile equipped with a navigation-grade INS is possible. © ICrOS 2022.

An MPPT control strategy based on the combination of adaptive nonlinear mutation particle swarm optimization algorithm is proposed. The algorithm uses the tanh function to control the inertia weight, balances the ability of particles to optimize globally and locally, uses the ISrU function to control the learning factor, balances the weight relationship between individual learning and social learning, and improves the convergence speed of the algorithm. The nonlinear Cauchy mutation operation is proposed to expand the scope of optimization;Finally, the perturbation and observation method is used to track locally near the maximum power point to reduce power oscillation. The simulation validates that the photovoltaic MPPT control strategy based on the improved particle swarm algorithm can effectively get the maximum power point under shading conditions and improve the output efficiency of the PV array. © 2024 IEEE.

MAGPNet: Multi-domain Attention-Guided Pyramid Network for Infrared Small Object detection

To overcome the obstacles of poor feature extraction and little prior information on the appearance of infrared dim small targets, we propose a multi-domain attention-guided pyramid network (MAGPNet). Specifically, we design three modules to ensure that salient features of small targets can be acquired and retained in the multi-scale feature maps. To improve the adaptability of the network for targets of different sizes, we design a kernel aggregation attention block with a receptive field attention branch and weight the feature maps under different perceptual fields with attention mechanism. Based on the research on human vision system, we further propose an adaptive local contrast measure module to enhance the local features of infrared small targets. With this parameterized component, we can implement the information aggregation of multi-scale contrast saliency maps. Finally, to fully utilize the information within spatial and channel domains in feature maps of different scales, we propose the mixed spatial-channel attention-guided fusion module to achieve high-quality fusion effects while ensuring that the small target features can be preserved at deep layers. Experiments on public datasets demonstrate that our MAGPNet can achieve a better performance over other state-of-the-art methods in terms of the intersection of union, Precision, recall, and F-measure. In addition, we conduct detailed ablation studies to verify the effectiveness of each component in our network. © 2024, Shanghai Jiao Tong University.

Full dC of offshore wind farms is the future development trend of large-scale offshore wind farms, however, the probability of dC line faults is high, and the use of dC circuit breakers can realise the fault ride-through of offshore full dC wind farms, improve the safe operation of the system during faults, and is one of the mainstream solutions to realise dC fault isolation. In this paper, a capacitive dC circuit breaker suitable for offshore full dC grid is proposed, which can effectively suppress the fault current by introducing a current limiting device. The topology and working principle of this circuit breaker are analysed, and the circuit breaker fault handling process is theoretically analysed. Finally, for the single-end equivalent system using capacitor-type dC circuit breaker, a simulation model is established in Matlab/Simulink software for verification, and the simulation results show that the proposed circuit breaker has a better current limiting effect and has the ability to isolate faults quickly. © 2024 IEEE.

Indoor positioning technologies for IoT sensing are attracting attention. We are currently exploring standard indoor positioning methods using IEEE 802.11 / Wi-Fi. In this paper, we utilize the IEEE802.11-2016 FTM (Fine Timing Measurement) protocol, which enables to calculate distances between devices and access points (APs). The ranging accuracy of FTM, however, varies depending on multipath propagation of wireless signals and device-specific factors. Therefore, we implemented FTM on two models, Google Pixel4 and Zenfone9, and conducted experiment studies in the gymnasium and corridor of our school to evaluate position detection accuracy. In the gymnasium, the average error was 1.42 m for Zenfone9, while 1.07 m for Pixel4. In the corridor, the average error was 0.66m for Zenfone9, whereas 2.47 m for Pixel4. © 2024 IEEE.
