The Internet of Things (IoT) allows physical devices to be connected over wireless networks, and while device-to-device (D2D) communication has become a promising technology for IoT, traditional solutions for D2D resource allocation are often computationally complex and time-consuming. In order to improve the computational efficiency and improve the generalization performance of the algorithm, a large-scale power control unsupervised learning framework algorithm based on Message Passing Graph Neural Network (MPGNN) was proposed, which aims to maximize the weighting and rate of all D2D links. To achieve the above goals, we first model the topology of the wireless network as a graph model, define the channel matrix as the graph structure, and then model the objective function of the system as a loss function and train the model parameters in the MPGNN with the help of the unsupervised learning model. After offline training, each D2D link can obtain the optimal power control strategy in a distributed manner according to the channel state information (CSI). Simulation shows that compared with the classic algorithm based on optimization theory, Weighted Minimum Mean Square Error (WMMSE), the computational efficiency of the proposed algorithm is increased by more than 50 times when the number of users is 100 pairs. In addition, compared with the traditional neural network algorithm, deep neural network (DNN), the proposed algorithm improves the generalization ability of the system under the same parameter settings. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

The goal of carbon emission peak and carbon neutrality requires China to vigorously develop renewable energy. However, renewable energy has obvious randomness and volatility. Therefore, it is necessary to configure energy storage systems for renewable energy stations to ensure the safe and stable operation of power systems. Given the problem of energy storage system configuration in renewable energy stations, it is necessary to consider the system load characteristics and design appropriate principles to formulate planned output curves for renewable energy stations, so that the joint output curve of renewable energy and energy storage system can match the system load curve as much as possible, which will reduce the system peak shaving pressure and promote the utilization of renewable energy. This paper first considers the impact of renewable energy stations with the different installed scales on the power system and designs the standardized supply curves differentially, and defines the supply curve deviation index to characterize the difference between the renewable energy-energy storage system joint output curve and the standardized supply curve. Then, to minimize energy storage system investment costs and supply deviation costs, an optimization model for energy storage system configuration in renewable energy stations is established, and output deviation control constraints are set to ensure that the operation of energy storage systems conforms to actual conditions. Finally, case studies analyze the energy storage system configuration results and the typical scenario operation results of a single renewable energy station and a renewable energy power generation base, which verify the rationality and effectiveness of the method proposed in this paper.(c) 2023 Published by Elsevier Ltd.

Bangladesh is a highly populated nation in the globe where 76% people live in the remote regions and 24% in metropolitan areas. Peoples living in distant places are encountering problems having no access to energy. In addition, electricity sector of Bangladesh relies on the fossil fuel like natural gas, coal, oil that are limited in supply. Huge potentiality of renewable resources like solar, biogas/biomass, wind, hydro might be an excellent solution for minimizing electricity crises. In this study, hybrid renewable energy like solar, wind and biogas resources are assessed in terms of availability and energy recovery potential. A field study has been done to gather the information regarding population, load demand, biogas and solar resources of the chosen rural regions of Chapai-nawabgonj district. Then a solar PV-wind-biogas based 100 kW hybrid power generating system is constructed utilizing HOMER (Hybrid Optimization Model for Electric Renewable). In comparison to all other combinations, the modeling results demonstrate that the combined Solar-PV-Wind-Diesel system has the lowest COE (cost of electricity) and NPC (net present cost). In Bangladesh's Chapai-Nawabgonj district, electricity produced by the planned hybrid power generating system may be used in some of the area's most distant locations. This technology lowers energy costs per kWh and CO2 emissions, which contributes to the creation of a sustainable environment. © 2023 IEEE.

Design of a robust and practicable SSI damping controller using H-infinity technique for series compensated DFIG-based wind farms

This paper designs a robust and practicable subsynchronous interaction (SSI) damping controller using H-infinity technique for the safe operation of series capacitor compensated wind farms (WFs) with doubly-fed induction generator (DFIG) wind turbines (WTs). Mixed sensitivity control design together with pole placement are formulated into a set of linear matrix inequalities (LMIs) to obtain the controller parameters. The LMI technique allows to include both desirable frequency and time domain specifications. The proposed damping controller is integrated into the WT controller (WTC) and receives the DFIG converter currents as inputs. The implementation of the proposed controller does not require any communication links between the WTs and WF secondary control layer. The controller output signals are applied to the inner control loops of DFIG converters and are dynamically limited for the desired fault-ride-through (FRT) performance. The effectiveness of the damping controller is verified through detailed electromagnetic transient (EMT) simulations. In these simulations, the complete medium-voltage (MV) collector grid is modeled with all details, and it is assumed that the wind speed at the location of each turbine follows a Gaussian distribution. The collected results confirm the accuracy of the modeling of the entire WF as an aggregated WT with the average wind speed. (c) 2023 The Authors. Published by Elsevier Ltd.

Brain-Computer Interface (BCI) is a device that translates intentionally modulated brain signals into control commands. Based on motor imagery (MI) and steady-state visual evoked potentials (SSVEP) recorded from human subjects, motor commands could be decoded and translated to achieve the desired movements. However, achieving high levels of accuracy and stability in online BCI remains a challenge that needs to be addressed. This study utilized a limited number of channels (C3, C4, O1, and O2) to extract EEG frequency domain features through continuous wavelet transform. Furthermore, the classifiers of Bayes, KNN, and SVM were employed to decode motion commands. Moreover, a majority voting strategy was adopted to improve the online accuracy of the proposed classification model. The research results indicated that incorporating the majority voting algorithm into the online BCI control process could improve the average accuracy of mobile vehicle direction control from 68.33% to 87.08%. © Beijing HIWING Scientific and Technological Information Institute 2024.

Terrain classification is a necessary and difficult task for all off-road robots. Most existing methods use images or proprioceptive sensors for recognition. However, while taking proprioceptive sensors as input requires more actual contact (which also means risks), images are susceptible to ambient light change. We also found that a combination of multiple optical channels in Lidars is quite useful for the identification of terrain types. In this paper, we designed a Lidar-camera fusion system fully utilizing information from Lidars and fusing depth to images to classify different types of terrain. The proposed network was tested on the dataset which includes asphalt, brick, cement, cobblestone, grass, and gravel. The accuracy achieves 99.471%, which shows its efficiency.

Currently, the development of spark ignition engine technology leads to energy-efficient and low-emission vehicle policies, which is indicated by programs, such as the Low Cost Green Car (LCGC) program, Electric Vehicle (EV), Hybrid Vehicle (HV), and vehicles with alternative fuels. The direction of these policies is due to the declining availability of fossil energy and the issue of global climate change. Furthermore, various efforts have been taken to resolve this problem. To realize energy-efficient vehicles, the development of spark ignition engine currently leads to the achievement of AFR stoichiometry (14.67). This allows the vehicle to operate with optimal power and good fuel economy. However, further improvement can be made by carefully analyzing the power requirements and fuel control. Therefore, this study offers a new method to improve fuel economy based on driver behavior aspects, which was applied by integrating steering operations (the driver’s behavior while operating the steering) and fuel control. The steering operation was designed with 3 clusters, namely the low, medium, and high. Similarly, vehicle speed was designed with 3 clusters, namely low, medium, and high., The fuel mode was designed based on the input steering operation, vehicle speed, and fuzzy logic. The simulation results were in the form of fuel modes, such as economizer and stoichiometry. The economizer regulates the AFR fuel in the lean mixture (15.4), while the stoichiometry adjusts the AFR at the ideal mixture (14.67), respectively. Therefore, the fuel economy was realized when the steering operation and vehicle speed were both in the low cluster. Based on the simulation, it was concluded that the technology application designed, has a very high potential of being applied in real vehicles to assist in realizing energy-efficient vehicles. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
