High-performance floating thermoelectric generator for all-day power supply

Thermoelectric generators (TEGs) offer notable benefits in harnessing diverse low-grade waste heat from the environment. However, the uninterrupted capture of these energy resources still remains a huge challenge. Herein, we have developed a temperature-adaptive floating thermoelectric generator (TAFTEG) by integrating a temperature-adaptive absorber/emitter (TAA/E) to synergistically exploit renewable energy from the sun, outer space, and the water bodies by leveraging diurnal spectrally selective absorption and nocturnal radiative cooling. The WxV1-xO2-based TAA/E demonstrates remarkably solar absorption of ∼96 % and a superior switching ability of dynamic thermal radiation modulation from the low emission of ∼45 % to high emission of ∼81 %. Assembled with 8 pairs of Bi2Te3-based TEG legs, the TAFTEG enables a stable temperature difference of 34°C under indoor solar irradiation (1 kW m−2), yielding a peak power output of ∼1.0 mW cm−2, and continuous all-day power supply under both clear and overcast conditions. This strategy paves a new avenue toward the round-the-clock power supply from ambient environments.

A Two-stage coordinated restoration scheme of hybrid AC/DC distribution grid considering cold load pickup and resilience enhancement

The ever-increasingly severe weather events have elevated the quest for resilience in distribution grids. Cold load pickup (CLPU), a common occurrence in buildings with thermostatically controlled loads (TCLs), generates a significant peak power demand when loads restart. With widespread TCLs distribution, the restoration speed and power level could be impacted by the conventional grid restoration scheme due to limited distribution generator (DG) capability and power supply paths. In this context, this paper proposes a two-stage coordinated restoration scheme based on the novel hybrid AC/DC distribution grid, encompassing the grid configuration level, information interaction level, and designed restoration flow. The typical delayed exponential model is used to characterize CLPU properties during extended outages. In the 1st stage, the contained coordinated restoration strategy decides the optimal load restoration sequence with CLPU concerned. Then, the grid loss optimization is carried out in stage 2 to generate the proper power reference for DGs and voltage source converters (VSCs) of hybrid grids. In case studies, four types of heterogeneous buildings with varied CLPU characteristics are deployed in the analyzed grid. It is verified that the proposed scheme could make effective aggregation and dispatching for multiple DGs, achieving an additional 11.3 hours of total load support, a 16.5% increase of DG utilization and an 11.7% enhancement of the resilience index compared to the conventional restoration scheme. Furthermore, this scheme demonstrates adaptability for resilience improvement under varied temperatures and fault locations.

Reducing carbon emissions through sustainable energy integration at off-grid cellular sites: a case study of Nepal

ABSTRACT Information and communication technology is the key enabler for digitalisation and increased productivity in cross-cutting sectors. Telephone towers are the main infrastructure to enable digital connectivity and renewable energy sources are used to supply power to mobile towers at off-grid areas. In this paper, the economic and environmental aspects of sustainable energy supply in off-grid sites have been evaluated. Three stand-alone sites having solar PV, diesel generators, and hybrid power solutions integrated with battery storage are taken for the study. The result shows the solar PV solution is economically feasible with an energy cost of 0.18$/kWh and environmentally adaptable. The diesel generator power supply has a higher energy cost of 0.59$/kWh and abundant CO2 emission of 421.85tCO2 for a life period. The hybrid power solution has better energy cost(0.38$/kWh) and CO2 emission (213.72tCO2) than the diesel generator. Considering reliability, the hybrid power solution has better performance in terms of energy cost and GHG emission. Solar PV solution has a key role in developing green infrastructure. A solar PV system integrated with a diesel generator and battery storage is a must for an uninterrupted power supply. The outcomes of the study encourage telecom operators to go for green cell towers sustainably.

Impact of pipe resistance on performance of supercritical carbon dioxide Brayton cycle system

This study develops a system simulation model based on the megawatt-class supercritical carbon dioxide Brayton cycle unit in Hengshui, China, to examine the effect of pipe section resistance on system performance. The results indicate that increased pressure loss in pipe sections significantly reduces power generation efficiency and power supply efficiency. Specifically, a 100 % increase in pressure loss results in 3.290 % and 4.377 % decreases in power generation efficiency and power supply efficiency, respectively. Moreover, higher pressure loss leads to increased CO2 mass flow rate at design power generation load. When the pressure loss is doubled, it requires a 17.593 % increase in CO2 mass flow rate to achieve the design power. Pressure loss in high-pressure section has minimal impact on system performance, while resistance in low-pressure section significantly affects it. For instance, a 100 % increase in pressure loss from the compressor outlet to the low temperature regenerator inlet causes a 0.37 % decrease in system power supply efficiency, and a similar increase from the high temperature regenerator outlet to the low temperature regenerator inlet leads to a 0.76 % decrease. These findings provide meaningful guidance for component design and piping layout optimization for similar systems.

Design, modeling, and simulation of a PV/diesel/battery hybrid energy system for an off-grid hospital in Ethiopia

In the pursuit of sustainable energy solutions, off-grid hybrid systems have emerged as a promising avenue, catering to the electrification needs of rural areas. These systems encompass a multifaceted approach, addressing concerns of reliability, sustainability, and environmental preservation. Leveraging advanced tools such as HOMER modeling, the design and simulation of hybrid off-grid systems, alongside the evaluation of existing diesel generator (DG) power supply, have become imperative. This paper embarks on a comprehensive exploration with the overarching objective of designing, modeling, and simulating an off-grid power system tailored for the Shinshicho Primary Hospital. Nestled in the heart of Shinshicho Town within the Kembata Tembaro Zone of Ethiopia, this healthcare facility stands as a focal point for community well-being. The proposed hybrid system integrates solar PV, diesel generators, and battery storage, offering a robust and resilient energy solution. Throughout the optimization process, a primary load demand of 276 kgwatt-hours per day and a peak load of 40 kW were pivotal considerations. The financial cost of this hybrid system results in an initial capital requirement of $160,500, complemented by operational and maintenance costs amounting to $14,824. Over the projected 20-year lifespan, the total net present cost (NPC) is estimated at $216,155. With these economic parameters in mind, the cost-effectiveness of the selected hybrid system is underscored by a cost of energy (CEO) of 0.187 dollars per kilowatt-hour. This metric not only highlights the economic viability of the proposed solution but also positions it as a sustainable and financially prudent choice for meeting the energy needs of Shinshicho Primary Hospital.

OPTIMAL SIZING OF SOLAR-WIND HYBRID MICROGRID USING IMPROVED GREY WOLF OPTIMIZATION ALGORITHM A CASE STUDY OF KADUNA - NIGERIA

This paper presents an improved grey wolf optimization algorithm (IGWOA) for optimal sizing of an isolated photovoltaic (PV), wind turbine (WT), and battery energy storage (BES) hybrid microgrid. To demonstrate the effectiveness of the proposed approach, atmospheric data sets comprising of wind, solar, and temperature of Kaduna International Airport were collected from Nigerian Meteorological Agency while the load demand data was collected from Kaduna International Airport Electricity Distribution Center. The microgrid optimal sizing was formulated as a constrained single objective optimization problem. Constraints including, loss of power supply probability (LPSP), power balance, generation limits and battery state of charge (SOC) were imposed. Three simulation scenarios were considered. Firstly, the target allowable maximum LPSP was fixed at 25% and the algorithm was able to determine the optimal sizing of the hybrid microgrid components and minimize the initial cost from 169,880.00 USD to 112,356.40 USD per annum resulting in 34% savings in cost. Secondly, the effect of the target allowable maximum LPSP variation was investigated, and it was found that the total installed capacity of the system decreases with increase in LPSP thereby decreasing the total cost. Additionally, a novel electricity price index (EPI) was introduced in order to quantify the degree of optimality of the solution. The EPI was found to increase exponentially with increase in LPSP, resulting in an EPI of < 0.05USD/kWh at 20% LPSP. Lastly, to validate the proposed approach, a comparative analysis between the IGWOA and other algorithms was carried out, and the proposed IGWOA proved applicable.

Fault recovery strategy for urban distribution networks using soft open points

AbstractIn recent years, the frequent occurrence of natural disasters has seriously threatened the security and stability of distribution networks. Amidst these natural disasters, researchers have increasingly focused on ensuring fault recovery in distribution networks. Soft open points (SOPs) are new types of power electronic devices that can effectively recover faults in distribution networks. When a fault occurs, SOPs can quickly block and isolate fault short‐circuit current, provide power access to non‐fault areas, and optimise the power flow of distribution networks. Based on the critical role of distributed generation (DG) power supply in fault recovery, this study proposes a method that leverages the synergistic capabilities of SOPs and DG to recover faults in distribution networks. By employing a binary particle swarm optimisation algorithm, this method effectively improves load recovery, reduces the number of switching operations, and minimises network loss. The proposed method was simulated and verified using the IEEE 33‐node and 99‐node systems.

ОЦЕНКА ЭФФЕКТИВНОСТИ ПОДАВЛЕНИЯ АММИАКА В ВОЗДУШНЫХ СРЕДАХ ПРОИЗВОДСТВЕННЫХ ПОМЕЩЕНИЙ С ИСПОЛЬЗОВАНИЕМ БАРЬЕРНОГО РАЗРЯДА

One of the main problems in the industrial production of livestock and poultry products is the neutralization of toxic gases in the air removed from livestock premises. Ozonation is used for this. Ozone is produced in dielectric barrier discharge installations. The disadvantages of the method include the dependence of the electrical characteristics of the dielectric barrier discharge on the parameters of the medium and the generation of nitrogen oxides. (Research purpose) The research purpose is determining the effectiveness of ammonia suppression by ozone generated in dielectric barrier discharge installations at various parameters of the generator operating mode. (Materials and methods) Established the effectiveness of ammonia suppression by ozone at various parameters of the ozone generator operation mode. A 25 percent aqueous solution of ammonia with controlled purging over the surface of the solution was used as an ammonia source. The dependences of the mass concentration of ozone (O3), nitrogen oxides (NOx) and hydrogen sulfide (H2S) at the generator output on the operating mode parameters were studied. It was shown that the range of changes in the concentration of gases varied within the following limits: ozone - from 180 to 4, ammonia - from 80 to 2, hydrogen sulfide - from 4 to 0, nitrogen oxides - from 0 to 130 milligrams per cubic meter. (Results and discussion) It was found that the concentration of ammonia decreased from 50 to 10 milligrams per cubic meter; the time to reach the specified values of the concentration of ammonia in the stream was 20-50 seconds; when ozone is generated in all operating modes, nitrogen oxides are formed in the weight ratio O3/NOx from 1.42/1 to 1/1. The dependences of the generation of ozone and nitrogen oxides on the input voltage of the generator power supply unit were determined. It was noted that the optimal pumping rate of plasma-forming gas (atmospheric air) ranged from 0.8 to 1.5 m/ s; the mass ratio of nitrogen oxides to ozone varies from 0.69 to 0.98, which is unacceptable for premises with permanent residence of animals and maintenance personnel. (Conclusions) It was stated that the results obtained in assessing the rational operating modes of ozonators allow us to formulate technical requirements for the development of a specialized ozone generator adapted for use in agricultural production.

Защита электрогенераторов объектов распределенной генерации от аварийных режимов

Distributed generation is a good solution for areas remote from centralized power supply sources as it helps increase the reliability of consumer operation. Distributed generation power supply systems use renewable sources of electricity, diesel generators and gasoline generators in the form of mobile power stations, which in most cases are not equipped with modern means of protection. This study presents an analysis of existing means of protecting electric generators from abnormal and emergency operating conditions, including voltage asymmetry, which is one of the factors reducing the service life of generators and is typical for rural electrical networks. During the analysis, the authors determined the main types of generator protection against emergency operation modes: protection of stator windings, protection against underfrequency and overfrequency, protection against undervoltage and overvoltage, protection against voltage (current) asymmetry. It is noted that the main cause of voltage asymmetry leading to mechanical vibration and rapid overheating of the rotor is single-phase loads in the system, which are unevenly distributed over three phases. The problem of voltage asymmetry is mainly solved by redistributing loads in transmission lines and/or installing compensating devices. However, in rural power supply systems, unbalanced load distribution is rarely corrected. The voltage asymmetry can be compensated through the use of hybrid active power filters of series compensation and improved control methods of these filters. Voltage converters that are effective in equalizing voltage asymmetry in PV systems can effectively protect small capacity diesel power generators provided that the use of additional equipment is economically viable.

The core and key of LIB is the development and application of new lithium storage materials and electrolyte materials. This paper summarizes the research and application status of the main key materials of LIB. By analyzing the development status and existing problems of mainstream energy efficiency improvement technologies, it can be seen that the energy efficiency of LIB still has great room for improvement in the aspects of key materials and manufacturing technologies. At present, the research status of new anode materials and solid electrolytes is very active, and these technologies are expected to improve the energy efficiency, safety and reliability of lithium batteries. In the future, with more research and innovation, we can expect to see these technologies make even greater breakthroughs in the battery field, driving the development of electric mobility and renewable energy storage.

Control of isolated hydrogen generation power supply for the DC power grid

The utilization of water electrolysis hydrogen in DC power grids can effectively improve the absorption and utilization of renewable energy, and hydrogen production power supply is a key equipment. This article designs an isolated DC hydrogen production power supply, which adopts a bidirectional active H-bridge topology and power modular design. In the process of hydrogen production, the use of constant current and constant voltage control, the development of control strategies for the hydrogen production process but the input current ripple of the electrolytic cell is heavy, so the driving pulse interleaving phase shift between power modules is adopted. The hydrogen production power supply can achieve a hydrogen production process with a small current ripple, and the feasibility and effectiveness of the hydrogen preparation power supply control strategy have been verified through simulation and experiments.

Comparative Study of Passivity, Model Predictive, and Passivity-Based Model Predictive Controllers in Uninterruptible Power Supply Applications

Voltage source converters are widely used in distributed generation (DG) and uninterruptible power supply (UPS) applications. This paper aims to find the controller that performs best when model changes occur in the system, showing insensitivity to parameter variations. A comparison of the finite control set model predictive controller (FCS-MPC), interconnection and damping assignment passivity-based controller (IDA-PBC), and passivity-based model predictive control (PB-MPC) reveals that the PB-MPC provides high resistance to these unexpected LC filter changes in the converter. The second aim of the paper is to reduce the total harmonic distortion (THD) of the output voltage of the three-phase voltage source inverter (VSI). A high total harmonic distortion (THD) value exists in the voltage waveform of the three-phase voltage source inverter (VSI), feeding a non-linear load. A MATLAB simulation was performed using three control techniques for a three-phase VSI feeding: linear load, unbalanced load, and non-linear load. The PB-MPC performs better than the FCS-MPC and IDA-PBC in terms of having a low THD value in the output voltage of the converter under all types of applied loads, improving the THD by up to 30%, and having low variation in THD with mismatched filter parameters, as shown in the bar charts in the results section. Overall, the PB-MPC controller improves the robustness under parameter mismatch and reduces the computational burden. PB-MPC reduces the THD value because it integrates power shaping and the injection of damping resistances into the VSI.

Load model and parameter measurement method of DBD for power supply design

Plasma is widely used in sterilization and disinfection, environmental treatment, and material surface modification. At present, the DBD load equivalent circuit model used in the design of dielectric barrier discharge (DBD) low-temperature plasma generator power supply mainly includes the nonlinear clamping model and linear resistance capacitance model, which have advantages and disadvantages in the research and application of DBD load. This paper focuses on the modeling and parameter acquisition method of the RC parallel DBD load linear model, adds measurement capacitance to the discharge load loop, and obtains RC parallel equivalent model parameters by Q-V and I-V Lissajous-Figure analysis. After the experimental data is processed, the simulation circuit model is built by MATLAB/SIMULINK, and the experimental results are compared with the simulation calculation results. They verify the feasibility of the DBD load parameter measurement scheme and comprehensively demonstrate that the DBD load linear resistance capacitance model has important guiding significance in the design of the DBD power supply.

Hybrid Power Generation Supply Chain Financing and Purchasing Strategies with Option Hedging against Disruption

Environmental pollution has stimulated cleaner and sustainable energy (CSE) resource consumption which fuels low-carbon electric-power growth. This consumption is particularly affected by two factors. One of them is the power grid’s capital size in the electricity supply chain (ESC) and the other is the carbon emission reduction level elasticity of electricity consumption. Further, the financial strategy directly exerts quantifiable influence on one of the factors of capital size, while the procurement strategy plays a role in another factor. However, the impact of strategic behavior on all participants in the ESC remains unexplored. Thus, we construct a game model for the ESC consisting of two heterogeneous power plants and a strategic power grid with financial constraints, in order to analyze the purchasing and financing strategies for low-carbon electric-power consumption and examine the profit scenario from the credit and option hedging. We find that for the power grid, high self-owned funds level or affluent credit line encourages procurement. And when considering the power grid funds are uniformly distributed on or are constant, this funds property variation surely imposes influence on the wind electricity purchases. We find price elasticity of demand shows monotonic on the purchase when the power grid funds are constant but not necessarily when funds are uniformly distributed. The two power plants pursue the most favorable scenario for profit-maximizing by means of credit interest rate. Whether the power plants increase the financial credit interest is contingent upon option portfolios, the grid’s fund property, and wind yield conditions. We also find whether the relations between the two power plants are competitive or complementary depending on the wind yield rate. Numerical study shows that when the power grid funds are uniformly distributed, executing the double option seems to be the most profitable choice for the power grid and the traditional energy power plant, whereas with the uniform distribution of the grid’s funds, executing the call option but abandoning put is the most profitable to the traditional energy power plant. Moreover, under the grid’s fund of uniform distribution, it can both motivate power user consumption for clean energy generation and expand the power grid’s capital size.

Designing globalized robust supply chain network for sustainable biomass-based power generation problem

The utilization of renewable energy sources to produce electricity is capable of relieving the pressure of limited natural resources and achieving the sustainability of future energy. This paper addresses a multi-period multi-feedstock multi-technology biomass-based power generation supply chain planning problem with parameter uncertainty, balancing economic, environmental, and social objectives simultaneously. However, the main challenges in optimizing this problem are correlated with multiple conflicting objectives and uncertain parameters. This study proposes a novel globalized robust goal programming model with goal constraints to balance three conflicting objectives using priority levels and characterize the uncertainty of unit emissions and social scores by inner–outer uncertainty sets. After transforming globalized robust environmental and social goal constraints into their equivalent forms, the tractable counterpart of the proposed model is obtained, which is mixed-integer linear programming (MILP). Finally, the effectiveness of the proposed model is demonstrated through a case study about the design of a sustainable biomass-based power generation supply chain (SBPSC) network in Hubei Province, China. Computational results reveal that by adjusting several parameters, environmental and social aspired goals consistently can achieve, whereas the economic objective is vulnerable to being influenced. Comparative studies with nominal goal programming model and robust goal programming model indicate that the proposed model is uncertainty-immunized and less conservative. Under investigated circumstances, the realized economic profit by the proposed model is approximately 42.5% higher than that of the robust goal programming model on average.

Capacity assessment and scheduling of battery storage systems for performance and reliability improvement of solar energy enhanced distribution systems

The intuition of the utilities in the power distribution system is to provide premium quality electricity to the consumers uninterruptedly and environment friendly. The inclusion of renewable energy sources (RES) in association with conventional power generation has undoubtedly made the distribution system clean and green to meet the dynamic load demand but invited significant instability and complexity to the system. The traditional power supply and stochastic photo voltaic (PV) generation can be managed in an organized way to meet the wide variability in power demand by using battery storage systems (BSSs). This paper presents a novel strategy to optimally determine the size and charging discharging scheduling of BSSs in a distribution system (DS) to enhance its performance and reliability. The DS technical performance and reliability improvement are collectively investigated using the weight-aggregated particle swarm optimization (WAPSO) technique. The proposed strategy has been implemented in 28-bus and 69-bus radial DS over the various seasons. The DS minimum voltage profile and reliability improvement have been performed by minimizing the SADPL, SADD, SAENS through optimal BSSs size and optimized charging discharging scheduling. Through the proposed strategy the percentage reductions in SADPL, SADD, SAENS in the 28-bus DS are found to be 0.18 %, 13 %, and 16 % respectively which expresses the efficacy of the present work. The comparative analysis of the outcomes, optimal power injection by BSSs with optimized scheduling, and sensitivity analysis has been performed.

Optimization of hydrogen fuel cell economy for next generation power supply

We are all very concerned about the diminishing sources of conventional energy sources. The rate at which fossil fuels are consumed exceeds the rate at which they are produced naturally. The result will be a global fuel shortage, which will cause numerous issues in various industries. The second factor is the pollution that these sources add to our environment, which gets worse as more of them are used, which lowers the standard of living on this planet. There is ongoing research into alternative fuel sources to address the global energy crisis and supply us with clean energy.Like electricity, hydrogen is an energy carrier capable of carrying enormous amounts of energy, potential replacement for fossil fuels in the transportation sector is hydrogen, which is favorable from an environmental standpoint. Using hydrogen in conjunction with fuel cells will be especially beneficial. In low-temperature operation, fuel cells operate more efficiently than typical battery/internal combustion engine combos and don't emit nitrogen oxides. Currently Steam-Methane Reforming [SMR] is the widely used hydrogen production technology. Which yields Carbon Monoxide and Carbon Dioxide as the by-products along with hydrogen. Even with Carbon Capture and Storage [CCS] such methods of hydrogen production cause the Greenhouse gas emissions, simultaneously increasing the cost of production.Many challenging scientific and technological issues will need to be solved in order to make a move into a hydrogen economy from the existing fossil fuel, including hydrogen storage and production, which will take decades to complete. As a result, hydrogen is still the fuel of the future rather than the present. Hydrogen is not a substitute for fuel; rather, it is a form of energy that must be converted into hydrogen starting with chemicals rich in hydrogen.
