Optimized control strategy of green buildings with PV generation and energy storage integration

Due to the pressure of the worldwide governments on environmental protection, the power supply mode of conventional buildings is meeting a continuous change. In order to reduce carbon dioxide emission, the green building, whose energy supply system has ph otovoltaic (PV) generation and energy storage (ES) integration, has received much attention. Different from the conventional building energy system, the coordination of the PV and ES may significantly influence the economy and operation stability of the gr een building operation, especially when the green building operates under an electric market. In this paper, an optimized control strategy for green buildings with PV and ES integration is proposed considering the electricity prices. The objective of the p roposed optimized control strategy is to minimize the electric cost while maintaining the operation stability of the green building. Firstly, the battery charging strategy and the optimal system operation strategy are analyzed under the normal conditions o f power generation and consumption. Then, according to the probability distribution of the power generation curves and power consumption curves, some typical scenes are divided for the modeling of the optimal economic model. Thirdly, the optimal economic m odel is reorganized by involving the active load, such as interruptible load and non interruptible load. Finally, the proposed optimized control strategy is solved from the optimal economic model in order to realize the regulation of energy storage and PV. The effectiveness of the proposed strategy is verified by the case studies.

Effect of Different Power Supply Modes on Inclusion in 304L Stainless Steel Electroslag Ingot

The use of low frequency or DC (i.e., direct current) operation in the electroslag remelting process may lead to the electrolysis of some oxides in the slag pool, which will adversely affect the cleanliness of the electroslag ingot. In order to confirm this view, the effect of different power supply modes on the oxygen content and inclusions in electroslag ingot has been studied by adopting the self-designed electroslag remelting furnace as experimental equipment. The pulse heating inert gas fusion-infra-red absorption method is used for analyzing oxygen content. The analysis of non-metallic inclusion is conducted using an automatic SEM (i.e., scanning electron microscope) made by the American ASPEX Company, where the inclusion type and the inclusion size are determined. Results show that the oxygen content in the electroslag ingot increase significantly compared with that in the consumable metal electrode, whether under the frequency of 50 Hz, low-frequency, or DC. When DCSP (i.e., the consumable electrode is connected to the cathode of the DC power supply), DCRP (i.e., the consumable electrode is connected to the anode of the DC power supply), 2 Hz, 10 Hz, and 50 Hz power supply modes are adopted, the oxygen content in electroslag ingot is 155.3 ppm, 100.4 ppm, 75.8 ppm, 66.3 ppm, and 43.2 ppm respectively. With the increase in oxygen content, the number of inclusions in electroslag ingots increases significantly, and the increased inclusions are mainly Al2O3 inclusions. Regardless of the power supply mode, the largest diameter of inclusion is less than 20 μm. The electrolysis of Al2O3 is the direct reason for the increase in oxygen in the electroslag ingot when CaF2-Al2O3 slag is used. With the decrease in frequency, the electrolysis trend increases, and the oxygen content and the number of inclusions also increase. However, most of the inclusions are regenerated with the decrease in metal pool temperature and solidification, so the size is fine.

Cascade-Responsive 2-DG Nanocapsules Encapsulate aV-siCPT1C Conjugates to Inhibit Glioblastoma through Multiple Inhibition of Energy Metabolism.

Aerobic glycolysis is the primary energy supply mode for glioblastoma (GBM) cells to maintain growth and proliferation. However, due to the metabolic reprogramming of tumor cells, GBM can still produce energy through fatty acid oxidation (FAO) and amino acid metabolism after blocking this metabolic pathway. In addition, GBM can provide a steady stream of nutrients through high-density neovascularization, which puts the block energy metabolism therapy for glioma in the situation of "internal and external problems". Herein, based on the abundant reactive oxygen species (ROS) and glutathione (GSH) in the tumor microenvironment and cytoplasm, we successfully designed and developed a cascade-responsive 2-DG nanocapsule delivery system. This nanocapsule contains a conjugate of anti-VEGFR2 monoclonal antibody (aV) and CPT1C siRNA (siCPT1C) linked by a disulfide cross-linker (aV-siCPT1C). The surface of this nanocapsule (2-DG/aV-siCPT1C NC) is loaded with the glycolysis inhibitor 2-DG, and it utilizes GLUT1, which is highly expressed on the blood-brain barrier (BBB) and GBM cells, to effectively penetrate the BBB and target GBM. The nanocapsule realizes multidrug codelivery, jointly blocks glycolysis and FAO of GBM, and reduces angiogenesis. Meanwhile, it also solves the problems of low delivery efficiency of mAb in the central nervous system (CNS) and easy degradation of siRNA. In general, this drug joint delivery strategy could open up a new avenue for the treatment of GBM.

Hybridised production of technetium-99m and technetium-101 with fluorine-18 on a low-energy biomedical cyclotron

New modes of production and supply of short-lived radioisotopes using accelerators are becoming attractive alternatives to the use of nuclear reactors. In this study, the use of a compact accelerator neutron source (CANS) was implemented to explore the production of 99mTc and 101Tc. Irradiations were performed with neutrons generated from a 16.5 MeV cyclotron utilising the 18O(p, n)18F reaction during routine 18F-fluorodeoxyglucose (FDG) production in a commercial radiopharmacy. Natural molybdenum targets in metal form were employed for the production of several Tc isotopes interest via (n, γ) reactions on 98Mo and 100Mo. The production of 99mTc and 101Tc under these conditions is considered and discussed.

Research on Highway Self-Consistent Energy System Planning with Uncertain Wind and Photovoltaic Power Output

Highways are a critical consumer of energy. The integration of the highway and the energy system (ES) is a proven method towards carbon neutrality. The increasing energy demands of highway transportation infrastructure and the development of distributed energy and energy storage technologies drive the coupling between the highway system (HS) and the energy supply network, which is becoming tighter than ever before. Many scholars have explored the mode and path of integrated transportation and energy development. However, the energy and transportation systems’ coupling relationship and the collaborative planning scheme have not been thoroughly studied. Facing the increasing interconnection between transportation and energy networks, as well as addressing the demand for clean energy in highway transportation effectively, this paper proposes a highway self-consistent energy system (HSCES) planning model integrating uncertain wind and photovoltaic (PV) power output, so as to analyze the energy supply mode of the HS and determine the multi-energy capacity configuration of the self-consistent energy system (SCES). Firstly, the mathematical model related to each micro-generator of the SCES and the load aggregation scenario of the HS is established. Secondly, considering the uncertainty of renewable energy, this paper focuses on wind and PV power generation, and abatement technology, under uncertain conditions to ensure the best solution for reliability. Thirdly, taking the economy, reliability and the renewable energy utilization rate of the system into account, the system planning model is established under the condition of ensuring the system correlation constraints. Finally, the proposed method is validated using a section of the highway transportation system in western China. The results show that the hybrid energy storage planning scheme can cause the system’s renewable energy utilization rate to reach 99.61%, and the system’s power supply reliability to reach 99.74%. Therefore, it is necessary to carry out coordinated planning while considering the characteristics of the HS and the ES, which can minimize the planning cost of a HSCES, reduce the waste of wind and solar energy, and ensure the reliability of the power supply for the HS.

Research on New Air Supply Mode of Fan-coil Unit Based on CFD

Fan coil unit air supply is one of the main air supply modes of air conditioning. The fan coil unit system generally adopts the air distribution form of upward supply and upward return on the same side. In this work, a static pressure box is added at the outlet of the fan coil, and a deflector with separate control direction is set at the outlet of the static pressure box. In summer, the combination of up-side air supply and up-attached down-flow air supply is adopted to adjust the deflector to control the distribution of cold air and keep the overall indoor temperature distribution consistent. In winter, the air supply outlet is transferred to the lower part of the fan coil, and the hot air is directly sent to the personnel activity area at the lower part of the room by the adhesive effect of the jet, effectively solving the indoor air stratification phenomenon in winter.

Constant current-exponential attenuation mode: A non-traditional power supply mode for electrocatalytic oxidation

Low average current efficiency (ACE) and high energy consumption (EC) have seriously hindered the industrial development of electrocatalytic oxidation (ECO) technology. Timely adjustment of the current output according to the attenuation law of the organic pollutants concentration during the reaction process can help to solve the low electrical energy utilization problem at source. In this study, a non-traditional power supply mode with “constant current-exponential attenuation” (Mode CC-EA) was proposed and applied to intermittent ECO systems. The current is first output in a constant state and then attenuated exponentially according to the decreasing law of pollutants concentration, enabling efficient use of electrons at all stages of the reaction, resulting in increased degradation rates and ACE, and reduced EC. Acidic red G (ARG) was used as the target pollutant and the degradation effects of the traditional constant current mode (Mode CC), the direct exponential attenuation mode (Mode EA) and the Mode CC-EA were compared with different evaluation parameters. The results showed that the optimized Mode EA (n4) and Mode CC-EA (70-n11) degraded ARG with an ACE of 5.28 and 6.09%, respectively, which were 1.26 and 1.45 times higher than Mode CC (4.2%). At the same time, the EC were 0.36 and 0.27 kWh gCOD−1, respectively, which were 12.2 and 34.2% lower than Mode CC (0.41 kWh gCOD−1). The parameters of Mode CC-EA were further optimized and used for the degradation of three typical dye wastewaters, crystal violet (CV), methylene blue (MB) and methyl orange (MO), to investigate their general applicability. The results showed that the optimized Mode CC-EA achieved higher decolorization rates, chemical oxygen demand (COD) and total organic carbon (TOC) removal rates for the four wastewaters, including ARG, than Mode CC within 120 min for the same total input charge. The ACE of Mode CC-EA was on average 1.3 times higher than that of Mode CC, while the EC was on average 25.3% lower. Mode CC-EA achieves efficient use of electrical energy while ensuring the catalytic effect, which is of great application for the efficient treatment of dye wastewater and significance for the industrial development of ECO technology.

Economic dispatch of CAES in an integrated energy system with cooling, heating, and electricity supplies

AbstractFlexible combined cooling, heating, and power (CCHP) systems are effective in integrating wind sources. As an attractive, clean, and large‐scale energy storage technique, the advanced adiabatic compressed air energy storage (AA‐CAES) can store and generate both electricity and heating, and also provide cooling during expansion under certain conditions. Although AA‐CAES has immense potential in multi‐energy supply systems, CCHP dispatch with AA‐CAES and wind power generation (WPG) is yet to be systematically studied. In this study, the economic dispatch of an AA‐CAES system equipped with WPG is addressed. The AA‐CAES system is comprehensively modelled by considering its thermal characteristics, air‐temperature changes due to heating exchange, air storage constraint, and other factors, particularly the heat supply to the air for expansion, which is a key factor that influences the cooling supply. Subsequently, the cooling, heating, and power of the AA‐CAES system are dispatched to minimise the operating cost under different supply modes. In conclusion, the proposed method is demonstrated using an integrated energy system in an industrial park, and the operation cost of the AA‐CAES system is minimised. The numerical results demonstrate that the participation of AA‐CAES in CCHP dispatch can curtail WPG and reduce operation costs. The economics of the different supply modes of AA‐CAES are also discussed.

An EMI susceptibility study of different integrated operational transconductance amplifiers

Abstract This paper presents a comparative EMI susceptibility study of different integrated operational transconductance amplifier (OTA) topologies. We analyzed conventional well-known amplifier topologies based on the Miller OTA and folded cascode concepts with lower power consumption. The output dc voltage shifts induced by power supply and input common mode high frequency disturbances are presented. On top of the EMI susceptibility comparison, we discuss PSRR and CMRR within large and small excitation signal with a new simulation setup. Even more, the back-gate connections of differential MOS pair in OTA input stage are investigated for EMI susceptibility impact as well.

Research on the construction of new energy microgrids for wind power generation based on green and low carbon

At present, the supply mode of fossil fuel as energy in China has caused more and more damage to the environment. In order to meet the demand for sustainable development, research on the construction of new energy microgrids for wind power generation based on green and low-carbon is proposed. Firstly, the equivalent model of the wind power generation system is established, and then the wind power generation new energy microgrid with a wind turbine as the core is built based on the specific value calculated by the model. Finally, the conventional new energy microgrid construction scheme is selected as the comparative object, and the comparative experiment is carried out to prove the practicability of the method. The comparative experimental results show that the microgrid constructed by the proposed green and low-carbon wind power generation new energy microgrid construction method is superior to the traditional construction scheme in operating power, can meet the green and low-carbon energy development needs, and can provide a reference value for similar research schemes.

PERSISTENCE WHILE ON LABELED MAINTENANCE DOSE AMONG BIO-EXPERIENCED PATIENTS WITH CROHN'S DISEASE INITIATED ON USTEKINUMAB COMPARED TO ADALIMUMAB

Abstract BACKGROUND In Crohn’s disease (CD), dose escalation on biologic therapy may be required to maintain effectiveness, while adverse events or non-response, among other factors, may lead to lack of persistence. Understanding persistence while on labeled maintenance dose is particularly important in bio-experienced patients with CD, as they may have reduced response to subsequent lines of therapy. This analysis compared persistence while on labeled maintenance dose among bio-experienced patients on ustekinumab versus adalimumab in the United States (US). METHODS Adults with CD initiated on ustekinumab or adalimumab (index date) between 09/23/2016 (ustekinumab approval for CD in the US) and 08/01/2019 were selected from IBM® MarketScan® Commercial Database. Patients were bio-experienced (≥1 claim for another CD-indicated biologic in the 12 months baseline period pre-index date). Patients with other auto-immune diseases at baseline were excluded. Cohorts were balanced on baseline characteristics using inverse probability of treatment weights. Persistence to the index agent while on labeled maintenance dose was defined as (1) no gaps between days of therapy supply >120 days for ustekinumab (2 x 8-week on-label maintenance dose interval) or >60 days for adalimumab (2 x days of supply mode) and (2) no dose change relative to the US label maintenance dose. It was assessed from index date until the earliest of discontinuation (event), dose change during maintenance phase (censoring), or last day of supply (censoring). Weighted Kaplan-Meier and Cox proportional hazards models adjusted for baseline classes of biologics were used to assess the outcome at 12 months post-index. RESULTS 903 bio-experienced patients with CD were included in the ustekinumab cohort (mean age 40.9 years old; 57.1% female) and 525 in the adalimumab cohort (mean age 41.3; 56.3% female). During the baseline period, 71.1% and 72.6% used corticosteroids, 41.2% and 40.8% used immunomodulators, and 11.1% and 12.6% had a prior CD-related surgery, in the ustekinumab and adalimumab cohorts, respectively. At 12 months post-index, the probability of persisting on the index biologic while on labeled maintenance dose was higher in the ustekinumab cohort versus adalimumab cohort (78.8% vs. 67.8%; Fig. 1). Patients in the ustekinumab versus adalimumab cohort had a 71% higher rate of persistence while on labeled maintenance dose (hazard ratio [HR] 1.71; 95% confidence interval: 1.31-2.23; P-value: <0.001*). CONCLUSIONS Bio-experienced patients with CD initiated on ustekinumab were significantly more persistent while on labeled maintenance dose compared to patients initiated on adalimumab. These results confirm results on persistence to biologics in bio-experienced patients with CD from a prior study.

Structural Design of a Special Machine Tool for Internal Cylindrical Ultrasonic-Assisted Electrochemical Grinding.

During the process of internal cylindrical ultrasonic-assisted electrochemical grinding (ICUAECG), both the workpiece and the conductive grinding wheel are rotating, the machining space is closed and narrow, the electrolyte is difficult to spray into the machining area, and the insulation between the workpiece and the machine bed is challenging. According to the machining characteristics of ICUAECG, the structure of a special machine tool was designed to mitigate these problems. In particular, the rotation, electrolyte supply, electric connection, and insulation modes of the workpiece clamping parts were studied, yielding a novel workpiece clamping- and rotating-device design. This structure can fully use the internal space of the hollow spindle of the machine tool, effectively reduce the external moving parts, and achieve the appropriate liquid injection angle of the electrolyte. The ultrasonic vibration system and its installation mechanism, the dressing device of the conductive grinding wheel, and the electric grinding spindle-mounting and -fixing device were analyzed in detail. Then, a special machine tool for ICUAECG was designed, the operability and feasibility of which were verified by experiments involving conductive grinding wheel dressing and ICUAECG.

Евапотранспірація та врожайність соняшнику і нуту за краплинного зрошення

Goal. Set the parameters of irrigation regimes, evapotranspiration (ETc) and crop and chickpea yields depending on the designs of drip irrigation systems and water supply regime. Methods. Shortterm field experiments, analytical and statistical methods of experimental data processing. The results. It has been proven that the method of laying irrigation pipelines of drip irrigation systems significantly affects the parameters of evapotranspiration, the water regime, and the yield of sunflower and chickpea in the conditions of the Dry Steppe. Thus, sunflower evapotranspiration parameters were at the level of 2,94–3,05 thousand m3/ha in non-irrigated conditions, 4,36–4,62 thousand m3/ha with underground placement of irrigation pipelines (at a depth of 0,3 m) and 4,73–5,24 thousand m3/ha for the above-ground placement of irrigation pipelines. The same parameters for growing chickpeas were: 3,15 thousand m3/ha in non-irrigated conditions, 5,47–5,76 thousand m3/ha under subsoil drip irrigation and 6,23–6,99 thousand m3/ha — for the above-ground placement of irrigation pipelines. The amount of evapotranspiration when implementing the pulse water supply regime was 4,85 thousand m3/ha and 5,69 thousand m3/ha for sunflower and chickpea, respectively. Conclusions. The introduction of subsurface drip irrigation is more appropriate for the cultivation of sunflower and chickpea, which is explained by their drought resistance. The variant with subsurface laying of irrigation pipelines of drip irrigation provided almost identical yield parameters with lower plant water consumption coefficients. Thus, the minimum water consumption coefficients (1077,8 m3/t — sunflower, 1329,7 m3/t — chickpea) were obtained under the condition of implementation of the pulse water supply mode. The same version of the experiment provided the highest level of crop yield — 4,50 t/ha for growing sunflowers and 4,28 t/ha for chickpeas.

A new means of energy supply driven by terahertz photons recovers related neural activity

Continuous and efficient energy capture represents a long-sought dream of mankind. The brain is a major energy-consuming organ; an adult brain accounts for about 2% of the body weight but consumes about 20% of the body's energy. However, it is still unclear how the brain achieves efficient use of energy. Here, using nerve cells as test subjects, we found that THz photons with a specific frequency can effectively restore the reduced frequency of action potentials caused by inadequate ATP supply, which has been demonstrated as a novel mode of energy supply, present photons emission at a particular frequency from the breaking of the ATP phosphate bond. This energy supply mechanism may play a key biophysical basis for explaining how the body efficiently obtains energy, because the quantized chemical reactions could have a high energy efficiency and ultrahigh selectivity compared with the traditional thermochemistry and photochemistry.

How can artificial neural networks approximate the brain?

The article reviews the history development of artificial neural networks (ANNs), then compares the differences between ANNs and brain networks in their constituent unit, network architecture, and dynamic principle. The authors offer five points of suggestion for ANNs development and ten questions to be investigated further for the interdisciplinary field of brain simulation. Even though brain is a super-complex system with 1011 neurons, its intelligence does depend rather on the neuronal type and their energy supply mode than the number of neurons. It might be possible for ANN development to follow a new direction that is a combination of multiple modules with different architecture principle and multiple computation, rather than very large scale of neural networks with much more uniformed units and hidden layers.

Study on transport phenomena and performance of proton exchange membrane fuel cell with radial flow fields

The radial flow field structure, which has the advantages of low pressure drop, good water removal and good mass transfer, is an emerging structure for proton exchange membrane fuel cell (PEMFC) flow fields. However, optimization work on the design the structure is scarce for a complex structure that is difficult to manufacture. A comprehensive three-dimensional, non-isothermal and single-phase mathematical model is developed to describe the flow and heat, mass and charge transfer processes in a PEMFC. The transport phenomena and cell performance of radial flow fields with different gradient channels and parallel flow fields are studied and compared using the commercial computational fluid dynamics (CFD) software Fluent®. The distribution of oxygen concentration, pressure drop and temperature with different radial lengths is obtained. The effects of gradient channels, gas supply modes and radial lengths on cell performance are investigated. The results show that radial flow fields could offer more uniform oxygen distributions and lower pressure drops compared with parallel flow fields. Larger gradient channel sizes contribute to larger transfer volumes and higher gas molar concentrations in the catalyst layers and lower pressures in channels. The counter-flow supply mode is superior to the co-flow supply mode because it can enable a higher oxygen velocity and hence a higher current density.

Multi-participant operation optimization for charging systems with orderly charging and cooperative game strategies considering carbon capture and uncertainties

In order to further enhance the utilization rate of renewable energy and achieve the goal of carbon emission reduction, this paper establishes a stable and clean energy supply mode of charging system and constructs a three-stage optimization and benefit distribution model. Firstly, the charging system structure is built with employing photovoltaic generator and carbon capture thermal power generator. Secondly, the charging load uncertainty is modeled by using Markov Chain where the differences of speeds of vehicles are considered. Thirdly, a deterministic charging optimization model is constructed in the first stage, with the objectives of economy, environment, energy utilization and load fluctuation; and then, in the second stage, the uncertainty of photovoltaic power generation is considered to formulate two types of information gap decision theory-based models. Finally, a double factor-involved benefit allocation model for the proposed charging system is constructed in the third stage, based on the Shapley method. The case study shows that: (1) the forecast error of charging load is smaller by considering quantity transfer and speed differences; (2) carbon capture and storage system reduces CO2 emission by 85.08 % and system's cost by 2.60 %; (3) Tripartite cooperation maximizes the system's benefits, and IGDT provides multiple strategies for dealing with PV uncertainty; (5) benefit allocation considering economy and environment is more rational and highlights the contribution of carbon capture system.

PECULIARITIES OF PARAMETERS OF AEROBIC AND ANAEROBIC PRODUCTIVITY DEPENDING ON THE COMPONENTS OF BODY WEIGHT IN YOUNG MALES FROM THE MOUNTAINOUS DISTRICTS OF ZAKARPATTIA.

The aim: To establish differences in the aerobic and anaerobic capacity in young males with different components of body weight who live in the mountainous districts of Zakarpattia region. Materials and methods: 124 young men aged 17-21 were examined to determine the aerobic and anaerobic capabilities of the body, taking into account the components of body weight. Results: The level of aerobic productivity, which reflects physical health, depends on the component composition of the body. The highest level of aerobic capacity in terms of the VО2 max rel. is found in young males who have normal body weight with a high and a very high relative content of skeletal muscle, a low relative content of fat, and a normal level of visceral fat. As a consequence, their physical health exceeds "safe health level", namely 42 ml∙min-1∙kg-1, and corresponds to "average" according to Ya.P. Piarnat's criteria. Conclusions: A high relative fat content negatively affects the functional capabilities of the body of young males in both aerobic and anaerobic modes of energy supply. With the growth in the relative content of skeletal muscles, the increase of the aerobic capacity of the body, as well as the growth of the capacity of alactic and lactic energy supply processes is observed. None of the examined males had "good" or "excellent" parameters of aerobic processes.

DEVELOPING OF A PORTABLE MICROWAVE CONVECTIVE DRYING PLANT FOR GRAIN STORED IN BULK

The data of the analysis of the application of electrophysical influences are presented and the choice of using a microwave field for the intensification of heat and mass transfer is justified; the results of a numerical experiment on the propagation of a microwave field and dissipated power in a dense grain layer at different material humidity when microwave energy is supplied through slit radiators combined with the duct of a ventilation installation. The development of combined grain drying modes in a dense stationary layer requires taking into account the maximum levels of permissible heating and the pattern of propagation of thermal fields during exposure. (Research purpose) The research purpose is developing the design of a portable ultra-high-frequency convective installation for drying grain stored in bulk. (Materials and methods) Presented a model of a portable installation for combined ultrahigh-frequency convective processing. A model of a waveguide-emitter was given for numerical simulation. (Results and discussion) A numerical experiment was conducted to determine the propagation of the microwave field in a layer of wheat of different humidity. (Conclusions) It was revealed that the results of modeling the distribution of the microwave field intensity in the grain mass can be used to develop modes of combined grain drying, taking into account the peculiarities of the propagation of thermal fields, power dissipation and the operation of field sources. It has been shown that as an intensifying factor of heat and mass transfer processes for a stationary grain layer, it is advisable to use a microwave field in a pulsed mode of operation combined with active ventilation. It was established that in order to influence the grain layer, it is necessary to use a microwave field with a frequency of 915 Megahertz, however, the absence of commercially available microwave field sources with a power of 200-1000 watts with air cooling limits this possibility. It was determined that the use of sources operating at a frequency of 2.45 Gigahertz as a microwave field is possible taking into account the development of pulsed modes of microwave field supply. It was stated that the use of an air duct with slit radiators allows for the supply of microwave energy to the required level in the height of the treated layer.
