Anomaly Detection of Distribution Network Based on Adversarial Dual Autoencoder
Authors: Chen Yu , Luo Wang , Hao Yunhe , Jiang Houming 
Published: December 2022

Abstract
Anomaly detection on attributed graphs aims to identify individuals or groups whose patterns deviate significantly from most samples, which is very important for internet security, power system, and other applications. Especially in the power system, the energy flow pattern of the distribution network is very similar to the graph topological constraints. Taking each equipment and bus as nodes and the relevant electrical measurement data as attributes, the distribution network fault location problem is mapped to the anomaly detection task on the attributed graph. The traditional GNN-based anomaly detection algorithm for distribution networks has some problems, such as over-smoothing and inefficient embedding learning. To solve the problem of anomaly detection in the distribution network, an anomaly detection algorithm based on adversarial dual autoencoder (DGAE_GAN) is proposed, which is composed of a structural encoder and attribute encoder based on residual connection GAT. Through joint learning, the attributed graph is mapped to the low-dimensional space, and the decoders reconstruct the attributed graph. Then, a discriminator is invited to learn the sample similarity, and the game strategy can effectively alleviate the over-smoothing problem. Finally, the anomaly node detection task is realized by calculating the reconstruction errors from both the structure and attribute levels. We conducted multiple experiments on three real-world datasets, and the IEEE standard example shows that our proposed model is superior to the existing methods.

Abstract
The Digital sub-band system is an indispensable technology for the development of modern society, which has a wide range of applications. This work is particularly concerned with developing applications for modulation techniques used in mobile communication. Based on MATLAB, this paper compared the modulation and demodulation of 2ASK, 2FSK, 2PSK, and QPSK horizontally and analysed the practical and theoretical error rates. With the constellation maps of 16QAM, 32QAM, 64QAM, and 256QAM, the relationship between the error rate and the signal-to-noise ratio was studied. In binary modulation systems, 2PSK has the best noise resistance and requires 6dB less SNR than 2ASK when employing the same demodulation approach. In addition, this paper outlined the technologies and modulation standards employed in the development of 1G-4G. To make the comparison clearer, the advantage, disadvantages, and modulation comparisons among 1G-5G are displayed. The analysis and research of digital sub-band modulation technology is the basis for developing new technology in the future.

Published: December 2022

Abstract
With the development of smart grids, highly automated power systems increasingly rely on communication networks, and research on the reliability, safety, and economy of heterogeneous communication networks is particularly important. Traditional network planning methods do not take into account network load problems, resulting in serious network congestion and long delays. Aiming at the above problems, this paper proposes a heterogeneous communication network planning method for a smart grid based on an improved ant colony algorithm. This method improves the original ant colony algorithm by updating the pheromone concentration of the network node in real time and realizes the planning of heterogeneous communication networks in the smart grid. Simulation results show that the proposed method has the advantages of avoiding local network congestion, reducing the average delay, and improving network stability.

Authors: Gong Qing , Zhao Lu , Fan Li 
Published: December 2022

Abstract
Distributed energy storage can provide node support for energy consumption, but there are still some shortcomings in the formulation of technical standards and overall development planning. Due to the current cost of electric energy storage, it is difficult to give full play to the advantages of energy storage application under the current electricity price mechanism and favorable policy conditions. From the perspective of external support and technical methods for electric energy storage, this paper studies the typical application mode and comprehensive quantitative evaluation of distributed energy storage in the distribution network and takes the actual operation scheme as a verification case.

Published: December 2022

Abstract
With the continuous change in urban power demand, many problems in the urban power system are exposed, and distribution network planning is one of the more prominent ones. In the operation of the distribution network, the access of distributed generation will have a certain degree of impact on power quality, relay protection, current protection of the distribution network, and energy consumption loss. Therefore, in order to improve the evaluation accuracy of the distribution network security evaluation model, obtain a more realistic situation evaluation value, and expand the overall evaluation scope, this paper constructs the distribution network operation security evaluation model under distributed generation access. Firstly, the subjective weight of evaluation is determined, and the evaluation index system of the power grid operation security situation is designed under the background of power access. Secondly, the multi-source extension fuzzy evaluation matrix is constructed, and the model is established by comprehensive weighting processing. Finally, the test experiment is carried out. The test results show that compared with the traditional power grid operation security evaluation model, the power grid situation evaluation value obtained by the distribution network operation security evaluation model constructed in this paper is relatively high. This shows that the model has a good evaluation effect on the operation security of the distribution network, with high evaluation authenticity and small error, and has a high practical application value.

Published: December 2022

Abstract
The state of health of lithium-ion batteries is an extremely important indicator for the safe operation of electrical equipment. In order to solve the problem that the capacity of Li-ion batteries is difficult to measure online, this paper proposes an online method based on the XGBoost algorithm to estimate the state of health (SOH). First, health characteristics are extracted from the discharge voltage profile to characterise the capacity of the Li-ion battery. XGBoost is then used to predict SOH based on capacity drop. results show that the proposed method is able to estimate SOH with a root mean square error of less than 1.2% respectively. Furthermore, the proposed method was used for model training and prediction in less than 1 second.

Published: December 2022

Abstract
Chromium contamination is one of the most common heavy metal pollutants. Degradation of highly toxic Cr(VI) by microbial remediation technology can open up a new way for environmentally friendly and efficient chromium pollution control. The adsorption and reduction kinetics of Cr(VI) by Enterobacter cloacae SKD were studied by the adsorption and reduction experiments of Cr(VI) by Enterobacter cloacae SKD. The mechanism of adsorption and reduction of Cr(VI) by Enterobacter cloacae SKD was revealed, and the characteristics of adsorption and reduction were determined. The results showed that the R2 value of the Langmuir model of chromium adsorption by Enterobacter cloacae SKD was 0.989, which was higher than the R2 value of the Freundlich model of 0.656, and the adsorption isotherm model was more consistent with the Langmuir model. Enterobacter cloacae SKD conformed to the second-order adsorption kinetic model, which indicated that the adsorption of Cr(VI) by Enterobacter cloacae was mainly chemical adsorption. The reduction kinetics of Cr(VI) is more in line with the second-order kinetic model. Through the study of the heavy metal chromium adsorption reduction mechanism, the theoretical basis was provided for the practical application of the late heavy metal chromium pollution organism restoration.

Authors: Wang Yan 
Published: December 2022

Abstract
This research paper mainly studied the microstructure and hardness of the weld bead and welding heat affected zone of ultrafine grain steel after CO2 gas-shielded welding. After normalizing and quenching heat treatment, the changes in microstructure and hardness of welded joints were studied. These experimental results showed that the microstructure of the weld bead of the welded joint was dendritic. The microstructure of weld bead was a mixed structure of proeutectoid ferrite, side plate ferrite, bainite, and pearlite. The microstructure of the overheated zone of HAZ under the as-welded condition was ferrite and pearlite with coarse grains, and the normalized zone was pearlite and ferrite with smaller grains than that of base metal. The microstructure of the normalized + quenched welded joint was a mixture of low carbon martensite, pearlite and ferrite, and the ferrite content was less. The hardness change of these welded joints was that the welded joint hardness after normalizing + quenching was significantly higher than that of welded joints before heat treatment.

Influence of CaO and Fe2O on the surface tension and structure of SiO2-Al2O3-CaO-Fe2O3-MgO synthetic slags
Authors: Guo Junli , Lu Deping , Hu Qiang , zou Jin 
Published: December 2022

Abstract
The surface tension of coal slags influences the adhesion between the slag and furnace walls in slagging gasifiers, which further influences the efficiency, maintenance cost and reliability of the gasifier. The influence of CaO and Fe2O3 on the surface tension and structure of synthetic slags were investigated. The results indicate that the surface tension linearly increases with the increase of CaO content in the synthetic slag. When Fe2O3 exceeds 3.8 mole%, the surface tension of synthetic slag increases slowly with the increase of Fe2O3, which is related to Fe2O3 acting as an intermediate oxide. The degree of polymerization and the electrostatic potential of ions are related to a variation in surface tension, and the number of unsatisfied bonds increases because the Si-O-Si network structure was depolymerized. Here, NBO/T cannot reflect the degree of depolymerization of slag due to the variation in intermediate Fe2O3 contents.

Published: December 2022

Abstract
The rapid development of portable smart devices and electric vehicles is placing greater demands on the energy density and safety of rechargeable secondary batteries. Lithium-ion batteries using the Solid State Electrolyte (SSE) are considered to be the most promising direction to achieve these goals. Among the latest electrolyte developments, chloride solid electrolytes have attracted much attention due to their physicochemical properties such as high ionic conductivity, ease of deformation and oxidative stability. In this paper, a one-dimensional model of a solid-state Li3HoCl6 battery is proposed based on COSMOL Multiphysics multi-physics field simulation software, and the charge-discharge curves and lithium-ion concentration variation curves at different discharge rates are obtained. The results show that the battery has a stable potential and relatively high-capacity density at low C rates (1.8C~14.4C). Therefore, it has application values at low currents and space for improvement at high currents.

Published: December 2022

Abstract
During the operation of nuclear power plants, it is necessary to monitor and evaluate the aging of cable materials. In this paper, we evaluate the irradiated use status of two types of cable insulation materials used in nuclear power plants-cross-linked polyethylene (XLPE) and ethylene propylene diene methylene (EPDM). Firstly, two kinds of cable materials are subjected to accelerated radiation aging with different cumulative doses, and the macro-mechanical properties and microstructure changes of the cable materials after different doses are studied. Analyze and test its hardness value, tensile strength, elongation retention at the break, scanning electron microscope, and oxidation induction temperature. The results show that after γ-ray irradiation, the cable hardness and the retention rate of elongation at break show a downward trend. Under the highest cumulative dose of 500kGy, the retention rate of elongation at break is greater than 50% of the failure index. The tensile strength decreases slightly, the microscopic morphology of the tensile section has holes, and the oxidation induction temperature decreases.

Abstract
The austenitic stainless steel 15-15Ti is one of the main candidate materials for the fuel cladding of the Lead-cooled Fast Reactor (LFR) due to its outstanding irradiation resistance and mechanical properties at high temperatures. The study of the corrosion behavior of 15-15Ti in LBE can help further investigate the service performance in a reactor. In this study, the static LBE corrosion of 15−15Ti was carried out for 1000 h at the temperature of 550°C and the oxygen concentration of 5×10−7 wt%. The samples were analyzed by Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectroscopy (EDS), and X-ray Diffraction (XRD). The results showed that 15-15Ti was oxidized and formed a duplex oxide film. The inner oxide film is continuous and the main component is FeCr2O4. The outer oxide film is composed of Fe3O4. The Fe3O4 oxides are loose and they could fall off from the surface.
Symbolic regression assisted design of perovskite-type OER electrocatalysts for oxygen evolution reaction (OER) in alkaline electrolyte
Authors: Li Wentao , Yang Fan , Zhang Junliang 
Published: December 2022

Abstract
Perovskite oxides are promising electrocatalysts for oxygen evolution reaction (OER) in alkaline electrolytes. With high activity and low cost, they are being pursued by researchers worldwide. However, due to the compositional and structural diversity of perovskite-type oxides, the conventional method based on experimental trials on thousands of elemental combinations is inefficient and time-consuming, which hampers the development of this type of electrocatalyst. Here we employed a symbolic regression (SR) method under a machine learning framework to build mathematical formulae that best fit datasets based on 105 experimentally studied perovskite-type electrocatalysts and identified a simple parameter as the OER activity descriptor. Results show that B-site cations with a large number of d electrons and a small radius, such as Ni4+, Co4+, and Fe4+, are beneficial to high OER activity in perovskite oxides, which provide a guide for materials design.

As a new type of solar energy utilization, solar photothermal water evaporation system has the characteristics of high photothermal conversion efficiency and green environmental protection, which can be widely used in the field of seawater desalination and sewage treatment. The bagasse carbonized by high-temperature pyrolysis was used as the photo-absorption material, and the polyurethane sponge-based aerogel photo-thermal conversion material was prepared with the double-network composite aerogel constructed by chitosan and polyurethane sponge as the substrate. It has good evaporation stability and is suitable for portable evaporation equipment. Moreover, when the carbonization temperature of carbonized bagasse was 500 °C and the addition amount was 1%, the evaporation performance of aerogel was the best. In the wavelength range of 200~2500 nm, its absorption rate can reach 98.2%, and its evaporation rate can reach 2.04 kg m−2h−1 at 1 kW m−2. In addition, the aerosol has good stability in general seawater and alkaline sewage, and is an effective method for solving seawater and sewage.

Abstract
Inhibitor is one of the important additive components in electrodeposited copper. As a common inhibitor, the concentration of PEG8000 has an important effect on electrodeposited copper. In this article, different concentrations of polyethylene glycol-based organic additives were added to the acidic electrolyte, and their effects on the electrochemical behavior of copper electrodeposition were investigated by galvanostatic test, cathodic polarization curve test, and cyclic voltammetry test. In addition, the surface morphology and crystallographic orientation of the obtained copper layers were analyzed by SEM and XRD.

Abstract
In the field of spacecraft space environment engineering, the impact of atomic oxygen on the performance of spacecraft is very critical. According to the relevant literature, temperature is an important factor affecting atomic oxygen. This paper is about atomic oxygen erosion influence on ITO/Kapton/Al based on different temperatures. The temperatures selected were 25 °C, 75 °C, 100 °C, 125 °C, and 150 °C respectively to research the possible influences of different temperatures on atomic oxygen simulation experiment effects. The ground simulation equipment releases a fluence of 9.0×1019 atoms/cm2 under a 10−2Pa vacuum. The mass of samples was measured by high-precision micro-electron balance before and after the experiment and the reaction ratio was calculated. Emissivity and solar absorbance were measured by the TEMP 2000A portable emissivity testing apparatus and LRSR 300 portable spectrum solar absorbance testing apparatus respectively. According to the experiment, it is shown that the ITO protects the base material well, and the mass loss and the reaction ratio of samples show inactive. Results also show that the effects on mass loss are little, but effects on the physical property changes are great by the temperature variation.
