Over the last few decades, the industrial sector's electrical energy demand has grown exponentially, altering the supply-and-demand balance. The trend toward Industry 4.0 compliant production facilities necessitates a greater demand for high-reliability power. Because severe production losses caused by power outages cannot be tolerated, an increasing number of large vital industrial processes integrate centralized high-quality, online UPS technology onto their network to establish a grid-to-load link and continuously condition dirty electricity from the national grid. These facilities distribute electrical power using either an MV or LV system. Based on the integration design, investigating ways to quantify energy efficiency savings of MV versus LV UPS system is required. This paper proposes strategic and technical interventions for these systems and assesses their electrical losses and budgetary ramifications. The paper also aims to contribute to the implementation of an energy efficiency plan and help facilities close power efficiency gaps. From the results obtained, the MV UPS system offers a significant reduction in energy consumption. Compared to the LV UPS system, annual energy losses are reduced by 46% at a load factor of 65%. A significant energy improvement is expected at higher load factors and in larger facilities where longer distribution cables are used. Compared to the LV UPS system, MV UPS saves R221 509 per meter of cable length increase and R31 457 per percentage increase in load factor.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 2","pages":"673-686"},"PeriodicalIF":3.5,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.2021","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, there is a common phenomenon where the propagation of hydraulic fracture heights is limited in the hydraulic fracturing process of strongly heterogeneous shale reservoirs. To clarify the reasons for the limited height propagation of hydraulic fractures in strongly heterogeneous shale reservoirs, numerical simulation methods were used to study the propagation patterns of hydraulic fractures in shale reservoirs under different levels of anisotropy, flow rate, viscosity, and stress differences. The results show that as the anisotropy value increases and the heterogeneity becomes stronger, it becomes more difficult for hydraulic fractures to expand along the fracture height direction, and the fracture width at the fracture opening becomes larger. For strongly heterogeneous shale reservoir, the hydraulic fracture height can be increased within a certain range by increasing the flow rate, viscosity, and stress difference. When the upper limit value is exceeded, the hydraulic fracture height of the strong heterogeneous shale reservoir gradually becomes stable, and the increasing trend is no longer obvious. The strong or weak heterogeneity caused by the inherent anisotropic characteristics of shale reservoirs affects the development and transformation effectiveness of shale reservoirs. The research in this article will provide some reference material and guidance for the efficient development of shale reservoirs.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 1","pages":"309-322"},"PeriodicalIF":3.5,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.1998","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143118088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the model of grid-connected VSPS-wind-solar HPS is established. Secondly, based on a calculating example, the transient characteristics of grid-connected VSPS-wind-solar HPS are analyzed by using numerical simulation. Then, the effects of grid parameters and capacity ratios on transient characteristics of the grid-connected VSPS-wind-solar HPS are revealed. Finally, the regulation of governor and frequency converter for the grid-connected VSPS-wind-solar HPS is illuminated. The results indicate that the influence of wind speed disturbance and light intensity disturbance on the whole grid-connected VSPS-wind-solar HPS can be effectively reduced by using the pitch angle controller and VSPS unit, and the overshoot of power grid frequency does not exceed 0.1%, and the adjustment time does not exceed 4.36 s. Compared to the isolated VSPS power station, the regulation quality of the transient characteristics of grid-connected VSPS power station is worse. The coupling effect between the wind power station and power grid is weak. The increase of the capacity ratios of VSPS power station and wind power station has both advantages and disadvantages for the transient process of rotational speed of pump-turbine. The increase of the capacity ratio of solar power station is disadvantageous for the transient process of rotational speed of pump-turbine. The regulation effect of the control link PI-1 plays a dominant role in the frequency converter. The effect of the parameters for the control links of frequency converter on the regulation quality of grid-connected VSPS-wind-solar HPS is weaker than that of governor.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 1","pages":"416-433"},"PeriodicalIF":3.5,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.2013","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in practice, they face practical limitations due to suboptimal electron transport, inadequate hole-suppression, photocatalytic instability, and susceptibility to other environmental factors. Many transition metal oxides such as ZnO and TiO2 have important excitonic properties that make them good electron transport layer (ETL) materials in PSCs. However, many of the PS limitations arise from inherent issues with these oxides. The high interest in TiO2 is due to its low toxicity, chemical stability, and the potential to enhance its excitonic performance through doping with many materials. The main limitations of TiO2 are its poor visible-light response by virtue of its wide bandgap of ~3.2 eV, and its high electron-hole (e-h) recombination rates, which are directly responsible for its low current densities. Transition metal oxide enhancements occur using either internal doping or surface sensitization. Of the added materials, graphene has exceptional electrical conductivity, high electron mobility, large surface area, and excellent mechanical properties, making it a near-ideal candidate to improve the performance of TiO2. This review examines the important advances in graphene-TiO2 (g-TiO2) composites for ETL application. By forming a composite with TiO2, graphene can significantly enhance electron transport, reduce recombination losses, and improve the overall stability of PSCs. We present the detailed rationale for and analysis of g-TiO2 for improved electron transport efficiency, enhanced stability, and boosted overall PSC performance with the objective of providing an authoritative resource for the field.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 1","pages":"4-26"},"PeriodicalIF":3.5,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.1878","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143115966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurate prediction and evaluation of heavy oil output during SAGD production is a key step of construction optimization design and economic evaluation. The traditional prediction model of heavy oil production does not fully consider many geomechanical factors, such as rock deformation and permeability dynamic evolution. In this paper, a new mathematical model of crude oil production-geomechanical coupling was established for three stages of the SAGD life cycle (steam chamber breakthrough stage, rising stage, and lateral dilation stage). The influence of the dynamic evolution of rock porosity and permeability on production was fully considered through the sensitivity coefficient of rock strain and permeability stress. It is found that the gap between the new model and the traditional model is larger when the strain and stress sensitivity of the reservoir body is larger. The value calculated by the conventional model is small when the reservoir dilates and large when the reservoir compresses. For Karamay heavy oil in Xinjiang, China, the steam breakout time predicted by the new model is 0.72, 1.50, 1.37, and 1.44 times the conventional model when the volumetric strain is 6%. The heavy oil production of Karamay, Xinjiang, China, Athabasca, and Cold Lake SAGD production areas in Canada was predicted. In the lateral dilation stage of the steam chamber, the predicted values of the model considering geomechanical factors were 1.44, 1.28, and 1.15 times the traditional model, respectively. This model can help field engineers obtain more accurate production of heavy oil and evaluate the significance of reservoir geomechanics in SAGD production.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 1","pages":"344-354"},"PeriodicalIF":3.5,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.2005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143115902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The SSPM primarily comprises a twin-screw expander (TSE), twin-screw compressor(TSC), electric motor, and generator. Initially, models were developed for a 300-MW subcritical intermediate reheat condensing steam turbine unit, an SSPM, and a desuperheater and pressure reducer(DPR). Subsequently, these models are incorporated into the Ebsilon Professional software to simulate the operational characteristics of the SSPM. The performance parameters of the two options are then compared and analyzed. Simulation results reveal that the operational characteristics of the SSPM closely correlate with the mass flow rate of the TSE. As the TSE mass flow rate varies from 47 to 91 t/h, the efficiency of the TSE declines from 66.3% to 65.3%, while the power performed by the SSPM increases from −2457.978 to 1558.469 kW. Under identical operating conditions, the SSPM scheme exhibits a 6.2%–12.4% improvement in efficiency compared to the DPR scheme. Building upon the aforementioned analysis, the SSPM demonstrates effective cascade utilization of heat steam energy and exhibits favorable regulation characteristics under variable operating conditions. Contrasted with traditional DPR, the SSPM notably mitigates constraints on steam extraction by boilers and enhances the maximum generation efficiency of a single unit.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 2","pages":"626-642"},"PeriodicalIF":3.5,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.2019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
