Virtual Power Plant with Renewable Energy Sources and Energy Storage Systems for Sustainable Power Grid-Formation, Control Techniques and Demand Response

As the climate crisis worsens, power grids are gradually transforming into a more sustainable state through renewable energy sources (RESs), energy storage systems (ESSs), and smart loads. Virtual power plants (VPP) are an emerging concept that can flexibly integrate distributed energy resources (DERs), managing manage the power output of each DER unit, as well as the power consumption of loads, to balance electricity supply and demand in real time. VPPs can participate in energy markets, enable self-scheduling of RESs, facilitate energy trading and sharing, and provide demand-side frequency control ancillary services (D-FCAS) to enhance the stability of the system frequency. As a result, studies considering VPPs have become the focus of recent energy research, with the purpose of reducing the uncertainty resulting from RESs distributed in the power grid and improving technology related to energy management system (EMS). However, comprehensive reviews of VPPs considering their formation, control techniques, and D-FCAS are still lacking in the literature. Therefore, this paper aims to provide a thorough overview of state-of-the-art VPP technologies for building sustainable power grids in the future. The review mainly considers the development of VPPs, the information transmission and control methods among DERs and loads in VPPs, as well as the relevant technologies for providing D-FCAS from VPPs. This review paper describes the significant economic, social, and environmental benefits of VPPs, as well as the technological advancements, challenges, and possible future research directions in VPP research.

Research on Information Transmission Technology Through the Water–Air Interface Combining a Sonar and a Radar

In order to realize the information transmission across the water-air interface, the radar has been used to detect the tiny surface perturbations caused by the underwater low-frequency sound source. Due to the differences of medium properties at the water-air interface, it is difficult for underwater targets to communicate with airborne platforms directly. In order to solve this problem, we propose the finite element method to establish the minute vibration model on the water surface caused by the underwater low-frequency sound source, and analyze the influence of sound source parameters on the tiny surface perturbations at the surface of water. Then we design the frame structure and synchronization signal of the single-carrier communication system, and propose a robust information transmission method across the water-air interface. Finally, we experimentally verify the information transmission method combining a low-frequency sonar and a millimeter-wave radar in an anechoic water tank. The experimental results show that the method we proposed can realize the information transmission across the water-air interface up to 500 bps.

L’évaluation du crédit marchand à Montréal dans la seconde moitié du dix-neuvième siècle

This article examines one of the most prominent and powerful credit rating agencies in North America, the Mercantile Agency and its Montréal-based counterpart, Dun, Wiman & Co. The paper considers the context surrounding the first North American credit rating agencies, their managers’ profiles, the specific characteristics of the Montréal offices and, finally, the two primary methods of information transmission offered by the agency: the reference book and the credit report. I argue that issuing the reference book resulted in increasing access to credit for companies with high capitalization rates from creditors who possessed a subscription. Meanwhile, credit reports allow for greater flexibility in interpretation than a credit score. They thus offer additional leeway to debtor merchants who have little capitalization precisely because the creditor can interpret in various ways the content of the written evaluation. Foremost, the article provides an introduction to credit rating agencies as well as a general overview of the Montréal branch of the Mercantile Agency. Finally, the purpose of this research is to contribute to historiography by presenting an institution of credit regulation that has yet to receive much attention from the field of Canadian history.

Experiments on direct chaotic differentially coherent data transmission in a wired communication channel

Methods of differentially coherent information transmission using noise signals are of interest because of the impossibility of implementing the known methods of correlation reception for such signals. With a potentially higher noise immunity compared to the methods of information transmission based on chaotic synchronization, however, they have a feature that does not allow transceivers to be implemented in practice. The transmitter and receiver of the scheme, based on already known methods of differentially coherent transmission, require a time delay comparable to the duration of the transmitted bits. With an analog implementation of the scheme this leads to a physical length of the delay line of tens of meters or more. Previously, the authors proposed and studied a differentially coherent transmission scheme in which there are no long delays. In this scheme, the duration of delays in the transmitter and receiver is determined not by the duration of the bit, but by the decay time of the autocorrelation function of the chaotic signal. Purpose of this work is to experimentally demonstrate the possibility of physical implementation of a direct-chaotic differentially coherent information transmission scheme in a wired communication channel. Methods. For this, a layout of the communication scheme, transmitting a binary data stream in the frequency range from 200 to 500 MHz, was designed and assembled. The layout is an ultrawideband differentially coherent transmitter and receiver connected via a wired channel. Results of the experiment are in full agreement with the previously obtained results of the analytical evaluations, as well as with the data of computer simulation. Conclusion. In the course of the research, a transceiver layout of a differentially coherent ultra-wideband direct chaotic communication scheme was developed, designed and manufactured. For the first time, experiments on the transmission of digital information were carried out on it, and thereby the practical feasibility and operability of the proposed direct chaotic differentially coherent transmission scheme were proved.

Исследование эффективности помехозащищенности радиоканала авиационной радиосвязи

When performing aviation flights the high-quality and reliable communication with the control room becomes important for ensuring the crew safety. The purpose of the study is to investigate the quality of aviation radio communication in different methods of information transmission for developing the technical solutions of radio communication perfection. The equipment used today is designed for instant selection of preset channels and data exchange at fixed operating frequencies of ground control points with aircraft radio equipment in the meter and decimeter ranges. The most important requirement for the aviation radio communication systems is to ensure a high level 
 of noise immunity including protection against active interference. There is considered the process of frequency changing, or frequency hops, as the most successful at the first stage of the study in order to find the least interference-prone operating frequency. The use of pseudorandom frequency changing of radio communication between the ground control points and aircraft radio equipment is studied as one of the ways of leveling interference effects. To increase the stability of the radio line, it is necessary to use digital methods of information transmission. The use of digital methods of encoding information leads to low-level errors in the processes of discretization, modulation, amplification, demodulation and filtering. Due to this, nonlinear quantization allows for a higher level of signal-to-noise ratio. With a constant power level of the transmitter it is possible to carry out stable communication even at higher values 
 of the signal-to-interference ratio, which generally leads to the increasing radio transmission range. Using highly robust coding methods, the probability of error can also be reduced. There are studied different parameters reflecting the quality of information transmission over the radio channel: speech intelligibility, probability of erroneous reception of symbols. Thus, the digital methods of information transmission have higher noise immunity compared to the analog ones, even without special protection measures. Using special measures (noise-proof coding, pseudorandom frequency changing) can significantly increase the jamming protection of the radio communication system.

Thermal Perception for Information Transmission: Theoretical Analysis, Device Design, and Experimental Verification.

Information transmission is a fundamental issue for human-computer interaction (HCI). Traditional interaction methods through visual, voice, and force haptics are very mature. However, the thermal perception (TP) for HCI is not studied in depth. This work proposes the TP-based information transmission framework. Firstly, we investigated the human hand-object contact heat transfer model and the temperature perception resolution of the hand and verified the feasibility of spatiotemporal temperature stimulation for information transmission by simulations. Then, a thermal device was designed, which utilized a 7×5 Peltier array, a water cooler, temperature sensors, and a control module to realize various static and dynamic spatiotemporal temperature patterns stimulation. Finally, we implemented a device prototype and recruited 20 subjects for experimental studies. The results show that the device can display various temperature patterns and provide thermal stimulations with high precision and speed. Furthermore, the subjects can accurately recognize different temperature values, icons, codes, and waveforms with their palm and fingers after a few times of training, which validates the TP-based information transmission method. Therefore, people can apply this method to interact with machines for information feedback, virtual reality, augmented reality, etc.

Flexible Pressure Sensor Decorated with MXene and Reduced Graphene Oxide Composites for Motion Detection, Information Transmission, and Pressure Sensing Performance.

Although fiber-based flexible piezoresistive pressure sensors have received extensive attention because of their simple fabrication and easy integration, the common practice of using a single material as the sensing layer often leads to unsatisfactory sensitivity and a limited sensing range. Herein, we exploit the combination of reduced graphene oxide (rGO) and two-dimensional transition-metal carbides and nitrides (MXene), use a polyester filament (PET) as the fiber matrix, and fabricate an MX/rGO PET-based flexible pressure sensor using the "dipping-drying" method. A systematic study is conducted concerning the effect of the dip-coating sequence and material combination on the sensor's resistance and sensitivity, which reveals that MX/rGO PET has the smallest resistance and the highest sensitivity (1.24 kPa-1). A series of tests are conducted to evaluate the pressure sensing characteristics of the MX/rGO PET-based pressure sensor, confirming its good linearity, fast response speed, low detection limit, and stable performance. In addition, the sensor has been successfully used to monitor various human joint activities and physiological signals such as breathing, demonstrating great application potential in the field of personal health care. To further enhance the practical utility, an APP has been designed to analyze and display the collected signals, and the constructed sensor network also provides an ingenious method for information encryption and transmission via pressure sensing. In all, the MX/rGO PET-based pressure sensor proposed in this work is expected to provide a competitive scheme for wearable flexible electronic devices in information transmission and human-computer interaction in the future.

An Optimized Digital Image Processing Algorithm for Digital Oil Painting

Human civilization’s accomplishments have grown with the passage of time and the advancement of society. With the fast growth of computer networks and information technology, the conventional method of information transmission based on words cannot fulfill the demands of people in the current era. As a result, in this age of extensive information and image processing techniques, images as a means of information sharing are becoming increasingly popular. As we know, digital image processing knowledge has a far-reaching impact in the field of artistic creation, among which the creation of oil painting is facing severe challenges. Aiming at the problem that the effect of digital oil painting is not ideal, this paper aims to study digital oil painting by using digital image processing technology. This paper first uses the image edge recognition based on the improved Canny algorithm to detect the edge of the oil painting image, then uses the nonlinear image enhancement algorithm to enhance the effect of the oil painting image, then uses the improved genetic algorithm to segment the image, and finally enlarges the oil painting image to calibrate the color of the oil painting image. Experiments reveal that the proposed approach outperforms existing algorithms in terms of edge detection data integrity, high-quality coefficient index of image enhancement, picture segmentation running time, and the ability to successfully increase the visual effect of oil painting.

In Situ Loading of Polypyrrole onto Aramid Nanofiber and Carbon Nanotube Aerogel Fibers as Physiology and Motion Sensors.

Nanocomposite conductive fiber has been newly developed as a lightweight material with high flexibility and strong weavability, which can meet the requirements of flexible wearable devices. Herein, lightweight porous aramid nanofibers (ANF) and carbon nanotube (CNT) aerogel fibers coated with polypyrrole (PPy) layers are prepared by a wet spinning method for motion detection and information transmission. The ANF/CNT/PPy aerogel fiber with low density (56.3 mg/cm3), conductivity (6.43 S/m), and tensile strength (2.88 MPa) were used as motion sensors with high sensitivity (0.12) and long life (1000 cycles). At the same time, the differential conductivity of aerogel fibers is utilized to reduce the information transmission time (up to 46%). High- and low-temperature-resistant (-196 to 100 °C) aerogel fibers are also available as a quick heater and ionic solution detector. In summary, the prepared ANF/CNT/PPy aerogel fiber can be used as a multifunctional sensor for human-health detection and motion monitoring.
