description Publicationkeyboard_double_arrow_right Article , Journal 2016Publisher:Institute of Electrical and Electronics Engineers (IEEE) Authors: Hyo Jin Jo; Dong Hoon Lee; In Seok Kim;Smart grids have attracted increasing interest in the field of industrial research. These systems allow electricity consumers to communicate with electrical systems using bidirectional communications. However, these bidirectional channels may introduce privacy threats to consumers. Considerable research has been conducted with the aim of resolving these threats. Unfortunately, a practical smart grid design with adequate efficiency and security functionalities has not yet been produced. In this paper, we propose lightweight privacy preserving metering protocols by designing a distributed authentication method to further increase the speed of the message authentication process. We confirmed the efficiency and security of our method by performing a detailed analysis.

This study exploits a superhydrophobic nanostructured aluminum tube to estimate electrical output for solid-water contact electrification inside a tubular system. The linearly proportional relationship of short-circuit current and open-circuit voltage to the detaching speed of water was determined by using a theoretical energy harvesting model and experimentation. A pioneering stick-type solid-water interacting triboelectric nanogenerator, called a SWING stick, was developed to harvest mechanical energy through solid-water contact electrification generated when the device is shaken by hand. The electrical output generated by various kinds of water from the environment was also measured to demonstrate the concept of the SWING stick as a compact triboelectric nanogenerator. Several SWING sticks were connected to show the feasibility of the device as a portable and compact source of direct power. The developed energy harvesting model and the SWING stick can provide a guideline for the design parameters to attain a desired electrical output; therefore, this study can significantly increase the applicability of a water-driven triboelectric nanogenerator.

Abstract Experiments on high pressure steam condensation inside a nearly horizontal tube were performed for application into Passive Auxiliary Feedwater System (PAFS) of Advanced Power Reactor Plus (APR+). At KAIST, a Single-tube COndensation experiment facility of PAFS (SCOP) was constructed. The one-through type open loop test, where steam circulation is driven by pressure difference between the steam generator and the venting valve, was conducted in order to compensate for insufficiency of the heater power. We found out that the open loop test produced the same condensation heat transfer coefficients as those of the closed loop within 1% difference. Using the open loop, we were able to generate the higher steam flow rate by three times than that done by the heater power. Sensitivity studies were performed to validate the heat transfer performance of the PAFS in regard to the pressure effect, the diameter effect and the angle effect. The operating range of experiments are 1–7 MPa (pressure), 50.4 mm (reference tube) and 33.4 mm (comparing tube) (tube outer diameter) and 2–4° (tube angle). The comparing tube gave 30% higher heat transfer coefficients over the reference tube. In our tests, the slug flow was not observed. Compared with the reference case with the inclined angle of 3°, the case with the inclined angle of 2° showed just a bit lower heat capacity without any transition into slug flow.

The novel reformer is a combined technology as a plasma combustor and a matrix burner. The sequential mechanism of in-line plasma-burner reformer can improve POX reforming in the higher hydrogen-rich gas production. In order to present the performance potential for the novel PBR, the characteristics of conversion and product gases were identified according to the O2/C ratio, total feed gas, CO2: CH4 ratio, and recirculation of reformed gas, and the results are as follows: The reforming characteristics for each variable were identified, and the optimal operating condition of the PMBR was O2/C ratio of 1.0 and total feed gas of 20 L/min. At this time, CH4 conversion was 64%, H2 selectivity was 39%, and H2/CO ratio was 1.13, which were the results applicable to the SOFC fuel cell stack for RPG (Residential Power Generator). Recirculation of reformed gas increased the amount of hydrogen and carbon monoxide, which are combustible gases, especially the amount of hydrogen. As a result, the hydrogen selectivity is improved, and high-quality gas can be produced.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Journal 2012Publisher:Elsevier BV Authors: Joon-Eon Yang;From the PSA point of view, the Fukushima accident of Japan in 2011 reveals some issues to be re-considered and/or improved in the PSA such as the limited scope of the PSA, site risk, etc. KAERI (Korea Atomic Energy Research Institute) has performed researches on the development of an integrated risk assessment framework related to some issues arisen after the Fukushima accident. This framework can cover the internal PSA model and external PSA models (fire, flooding, and seismic PSA models) in the full power and the low power-shutdown modes. This framework also integrates level 1, 2 and 3 PSA to quantify the risk of nuclear facilities more efficiently and consistently. We expect that this framework will be helpful to resolve the issue regarding the limited scope of PSA and to reduce some inconsistencies that might exist between (1) the internal and external PSA, and (2) full power mode PSA and low power-shutdown PSA models. In addition, KAERI is starting researches related to the extreme external events, the risk assessment of spent fuel pool, and the site risk. These emerging issues will be incorporated into the integrated risk assessment framework. In this paper the integrated risk assessment framework and the research activities on the emerging issues are outlined.

Reese;AbstractImproving the long-term stability of perovskite solar cells is critical to the deployment of this technology. Despite the great emphasis laid on stability-related investigations, publications lack consistency in experimental procedures and parameters reported. It is therefore challenging to reproduce and compare results and thereby develop a deep understanding of degradation mechanisms. Here, we report a consensus between researchers in the field on procedures for testing perovskite solar cell stability, which are based on the International Summit on Organic Photovoltaic Stability (ISOS) protocols. We propose additional procedures to account for properties specific to PSCs such as ion redistribution under electric fields, reversible degradation and to distinguish ambient-induced degradation from other stress factors. These protocols are not intended as a replacement of the existing qualification standards, but rather they aim to unify the stability assessment and to understand failure modes. Finally, we identify key procedural information which we suggest reporting in publications to improve reproducibility and enable large data set analysis.

A 100 kW three-phase Grid-Tied MATLAB/Simulink model is used to analyze the system response during unbalance conditions. The simulation results of designed FRT scheme are critically compared with conventionally adopted FRT scheme i.e. crowbar circuitry. However, for inverter control proportional integrator (PI) controller is used. Moreover, the analysis is carried out for faults at point of common-coupling (PCC) as well as 5-km away from PCC. The obtained simulated results of PI controller with well-designed FRT scheme authenticates stable, minimum oscillation, ripples free, robust and fast performance for unbalance fault variables as compared to previous work.

For experiments, injection rates and macroscopic spray characteristics were investigated at various injection parameters by using an injection rate system and a spray visualization system. The combustion and emission characteristics were also obtained from the modified engine for DME fuel and emission measurement equipment. For numerical approaches, the combustion characteristics of DME fueled engine were predicted by a 3D-CFD code, the KIVA code coupled with the CHEMKIN (KIVA-CHEMKN) and spray behavior and evaporation were calculated by considering the thermo-chemical properties of DME. In order to calculate the fuel oxidation and emission formation such as NOx, a detailed chemical kinetic mechanism which was composed of 83 species and 360 reaction paths was considered. To simulate soot emission, two-step phenomenological model was applied. Both experimental and numerical results indicate that injection delay, ignition delay, and combustion duration of DME are shorter than that of diesel because of good evaporation and mixing characteristics. The pressure history predicted by the KIVA code agrees well with the measurements from the test engine. The amount of NOx emission was predicted by the reduced NOx mechanism shows good agreements to the experiments.

Computational fluid dynamics is used to simulate laminar ascending mixed convection flow of a heat-generating fluid in a vertical cylinder with uniformly cooled wall, based on a liquid nuclear fuel concept. A new non-dimensional parameter, the IHG-flux number Ω, is developed to express the balance of axial convection versus radial conduction heat transfer. It was found that heat transfer behaviour depends on this parameter, and it can be used as the transition criterion to categorise the simulated results into three distinct heat transfer regimes. A heat transfer correlation using Ω was also developed for Regime I with small values of Ω, where convection and conduction effects are balanced in a stable flow. In Regime II at intermediate Ω, stronger convection gives rise to flow instability. In Regime III with large Ω, convection dominates and the temperature profile inverts so that the maximum temperature occurs at the wall, while instability remains likely.

description Publicationkeyboard_double_arrow_right Article , Journal 2016Publisher:Institute of Electrical and Electronics Engineers (IEEE) Authors: Hyo Jin Jo; Dong Hoon Lee; In Seok Kim;Smart grids have attracted increasing interest in the field of industrial research. These systems allow electricity consumers to communicate with electrical systems using bidirectional communications. However, these bidirectional channels may introduce privacy threats to consumers. Considerable research has been conducted with the aim of resolving these threats. Unfortunately, a practical smart grid design with adequate efficiency and security functionalities has not yet been produced. In this paper, we propose lightweight privacy preserving metering protocols by designing a distributed authentication method to further increase the speed of the message authentication process. We confirmed the efficiency and security of our method by performing a detailed analysis.

This study exploits a superhydrophobic nanostructured aluminum tube to estimate electrical output for solid-water contact electrification inside a tubular system. The linearly proportional relationship of short-circuit current and open-circuit voltage to the detaching speed of water was determined by using a theoretical energy harvesting model and experimentation. A pioneering stick-type solid-water interacting triboelectric nanogenerator, called a SWING stick, was developed to harvest mechanical energy through solid-water contact electrification generated when the device is shaken by hand. The electrical output generated by various kinds of water from the environment was also measured to demonstrate the concept of the SWING stick as a compact triboelectric nanogenerator. Several SWING sticks were connected to show the feasibility of the device as a portable and compact source of direct power. The developed energy harvesting model and the SWING stick can provide a guideline for the design parameters to attain a desired electrical output; therefore, this study can significantly increase the applicability of a water-driven triboelectric nanogenerator.

Abstract Experiments on high pressure steam condensation inside a nearly horizontal tube were performed for application into Passive Auxiliary Feedwater System (PAFS) of Advanced Power Reactor Plus (APR+). At KAIST, a Single-tube COndensation experiment facility of PAFS (SCOP) was constructed. The one-through type open loop test, where steam circulation is driven by pressure difference between the steam generator and the venting valve, was conducted in order to compensate for insufficiency of the heater power. We found out that the open loop test produced the same condensation heat transfer coefficients as those of the closed loop within 1% difference. Using the open loop, we were able to generate the higher steam flow rate by three times than that done by the heater power. Sensitivity studies were performed to validate the heat transfer performance of the PAFS in regard to the pressure effect, the diameter effect and the angle effect. The operating range of experiments are 1–7 MPa (pressure), 50.4 mm (reference tube) and 33.4 mm (comparing tube) (tube outer diameter) and 2–4° (tube angle). The comparing tube gave 30% higher heat transfer coefficients over the reference tube. In our tests, the slug flow was not observed. Compared with the reference case with the inclined angle of 3°, the case with the inclined angle of 2° showed just a bit lower heat capacity without any transition into slug flow.

The novel reformer is a combined technology as a plasma combustor and a matrix burner. The sequential mechanism of in-line plasma-burner reformer can improve POX reforming in the higher hydrogen-rich gas production. In order to present the performance potential for the novel PBR, the characteristics of conversion and product gases were identified according to the O2/C ratio, total feed gas, CO2: CH4 ratio, and recirculation of reformed gas, and the results are as follows: The reforming characteristics for each variable were identified, and the optimal operating condition of the PMBR was O2/C ratio of 1.0 and total feed gas of 20 L/min. At this time, CH4 conversion was 64%, H2 selectivity was 39%, and H2/CO ratio was 1.13, which were the results applicable to the SOFC fuel cell stack for RPG (Residential Power Generator). Recirculation of reformed gas increased the amount of hydrogen and carbon monoxide, which are combustible gases, especially the amount of hydrogen. As a result, the hydrogen selectivity is improved, and high-quality gas can be produced.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Journal 2012Publisher:Elsevier BV Authors: Joon-Eon Yang;From the PSA point of view, the Fukushima accident of Japan in 2011 reveals some issues to be re-considered and/or improved in the PSA such as the limited scope of the PSA, site risk, etc. KAERI (Korea Atomic Energy Research Institute) has performed researches on the development of an integrated risk assessment framework related to some issues arisen after the Fukushima accident. This framework can cover the internal PSA model and external PSA models (fire, flooding, and seismic PSA models) in the full power and the low power-shutdown modes. This framework also integrates level 1, 2 and 3 PSA to quantify the risk of nuclear facilities more efficiently and consistently. We expect that this framework will be helpful to resolve the issue regarding the limited scope of PSA and to reduce some inconsistencies that might exist between (1) the internal and external PSA, and (2) full power mode PSA and low power-shutdown PSA models. In addition, KAERI is starting researches related to the extreme external events, the risk assessment of spent fuel pool, and the site risk. These emerging issues will be incorporated into the integrated risk assessment framework. In this paper the integrated risk assessment framework and the research activities on the emerging issues are outlined.

Reese;AbstractImproving the long-term stability of perovskite solar cells is critical to the deployment of this technology. Despite the great emphasis laid on stability-related investigations, publications lack consistency in experimental procedures and parameters reported. It is therefore challenging to reproduce and compare results and thereby develop a deep understanding of degradation mechanisms. Here, we report a consensus between researchers in the field on procedures for testing perovskite solar cell stability, which are based on the International Summit on Organic Photovoltaic Stability (ISOS) protocols. We propose additional procedures to account for properties specific to PSCs such as ion redistribution under electric fields, reversible degradation and to distinguish ambient-induced degradation from other stress factors. These protocols are not intended as a replacement of the existing qualification standards, but rather they aim to unify the stability assessment and to understand failure modes. Finally, we identify key procedural information which we suggest reporting in publications to improve reproducibility and enable large data set analysis.

A 100 kW three-phase Grid-Tied MATLAB/Simulink model is used to analyze the system response during unbalance conditions. The simulation results of designed FRT scheme are critically compared with conventionally adopted FRT scheme i.e. crowbar circuitry. However, for inverter control proportional integrator (PI) controller is used. Moreover, the analysis is carried out for faults at point of common-coupling (PCC) as well as 5-km away from PCC. The obtained simulated results of PI controller with well-designed FRT scheme authenticates stable, minimum oscillation, ripples free, robust and fast performance for unbalance fault variables as compared to previous work.

For experiments, injection rates and macroscopic spray characteristics were investigated at various injection parameters by using an injection rate system and a spray visualization system. The combustion and emission characteristics were also obtained from the modified engine for DME fuel and emission measurement equipment. For numerical approaches, the combustion characteristics of DME fueled engine were predicted by a 3D-CFD code, the KIVA code coupled with the CHEMKIN (KIVA-CHEMKN) and spray behavior and evaporation were calculated by considering the thermo-chemical properties of DME. In order to calculate the fuel oxidation and emission formation such as NOx, a detailed chemical kinetic mechanism which was composed of 83 species and 360 reaction paths was considered. To simulate soot emission, two-step phenomenological model was applied. Both experimental and numerical results indicate that injection delay, ignition delay, and combustion duration of DME are shorter than that of diesel because of good evaporation and mixing characteristics. The pressure history predicted by the KIVA code agrees well with the measurements from the test engine. The amount of NOx emission was predicted by the reduced NOx mechanism shows good agreements to the experiments.

Computational fluid dynamics is used to simulate laminar ascending mixed convection flow of a heat-generating fluid in a vertical cylinder with uniformly cooled wall, based on a liquid nuclear fuel concept. A new non-dimensional parameter, the IHG-flux number Ω, is developed to express the balance of axial convection versus radial conduction heat transfer. It was found that heat transfer behaviour depends on this parameter, and it can be used as the transition criterion to categorise the simulated results into three distinct heat transfer regimes. A heat transfer correlation using Ω was also developed for Regime I with small values of Ω, where convection and conduction effects are balanced in a stable flow. In Regime II at intermediate Ω, stronger convection gives rise to flow instability. In Regime III with large Ω, convection dominates and the temperature profile inverts so that the maximum temperature occurs at the wall, while instability remains likely.
