  • Evaluation of residential power supply by photovoltaics and electric vehicles

    Takuya Higashitani, Takashi Ikegami, Akane Uemichi, Atsushi Akisawa

    Renewable Energy   178   745 - 756  2021.11

     View Summary

    Electric vehicles (EVs) and vehicle-to-home (V2H) technologies are expected to be used as domestic electricity storage systems, thereby promoting the self-consumption of photovoltaic (PV) power. The purpose of this study was to evaluate the profitability of V2H installation, the optimal facility configuration and the energy performance of V2H, while considering a diversity of household types and storage facility options. We optimized the facilities and operation strategy of a residential energy system under many scenarios with different electricity demand profiles, automobile usage patterns and available areas for PV installation. The results showed that a V2H system should generally be installed instead of a stationary battery (SB), but combining a V2H system with a SB is more economical for households with long EV absence times. Additionally, V2H is profitable for households with short EV absence times, large available areas for PV installation and high electricity demand. Furthermore, V2H exhibits superior energy independence and energy-saving effects for households whose annual PV generation exceeds the yearly household electricity demand.

  • Multiple-input multiple-output control of diesel combustion using a control-oriented model

    Yudai Yamasaki, Ryosuke Ikemura, Motoki Takahashi, Shigehiko Kaneko, Akane Uemichi

    International Journal of Engine Research   20 ( 10 ) 1005 - 1016  2019.12  [Refereed]

     View Summary

    In this study, a multiple-input multiple-output feedforward controller for use with multiple-point fuel injection systems is applied to a diesel engine using an original control-oriented model. The target-tracking performance of this multiple-input multiple-output feedforward controller was then tested in terms of how well the controller adjusts the fuel delivery ratios to the pilot injection, pre-injection, main fuel injection, and the main fuel injection timing, and controls the in-cylinder peak pressure and its timing. Control experiments are conducted at different engine outputs and speeds while changing the targets of the in-cylinder peak pressure and its timing. The controller is able to track the varying targets within an acceptable error included in the original model. The calculation time, which is almost double that of a single-input single-output controller, is sufficiently fast to derive the applicable inputs.

  • Combustion oscillation characteristics of hydrogen-rich fuel

    Akane Uemichi, Ippei Kanetsuki, Shigehiko Kaneko

    Lecture Notes in Mechanical Engineering     371 - 376  2019  [Refereed]

     View Summary

    In this study, combustion oscillation characteristics of hydrogen-rich fuel were investigated. The experimental results fueled by mixture of natural gas and hydrogen show that hydrogen-rich combustion influences on the oscillating fre-quencies. In the case of only natural gas, the single oscillating frequency around 350 Hz is obtained, and in the hydrogen-containing fuel case, the double oscillating frequencies around 200 and 400 Hz are measured. However, the latter oscillating frequencies could not be derived from the one-dimensional acoustic analysis. Therefore, to figure out these frequencies, the acoustic impedance was measured experimentally and the oscillating frequencies were re-calculated using the measured acoustic impedance as the acoustic boundary conditions. As a result, the 200, 350, and 400 Hz frequencies could be expressed using the acoustic impedances.

  • Multi-objective optimization to determine installation capacity of distributed power generation equipment considering energy-resilience against disasters

    Akane Uemichi, Masaaki Yagi, Ryo Oikawa, Yudai Yamasaki, Shigehiko Kaneko

    Energy Procedia   158 ( - ) 6538 - 6543  2019  [Refereed]

     View Summary

    In 2017, the Mistry of Health, Labor, and Welfare in Japan added a requirement for domestic disaster base hospitals to install electric power generation equipment with a generation capacity at least 60% of usual demand for securing business continuity. In this study, we developed a multi-objective optimization tool for assisting the determination of the capacity of distributed generation equipment and contract plans considering energy-resiliency after a disaster. The selected objective functions are a total cost representing economy and environment, and an expected value of power shortage ratio after the catastrophe representing energy-resiliency. As a result, our developed tool could obtain the Pareto-optimal solutions for various size hospitals on the parameter plane of the two objective functions. As well as total costs, for all optimal solutions, the expected value of power shortage ratio under disaster situation resulted in less than 40% suggesting that the national requirement standard is satisfied. Then, the cluster analysis was carried out to grasp the tendency of optimal solutions. From the analysis of average value for each cluster, it is shown that the optimal introductory capacities of gas engine generators and storage batteries couple through the outage probabilities of gas supply. Furthermore, the optimal capacity of photovoltaic is much larger than the one assumed to install on the estimated rooftop area of the hospital building, which suggests that hospital can take an option to introduce more photovoltaics to an adjacent area if possible.

  • Formation of ultra-lean comet-like flame in swirling hydrogen–air flow

    Akane Uemichi, Kento Kouzaki, Kazunori Warabi, Kohei Shimamura, Makihito Nishioka

    Combustion and Flame   196   314 - 324  2018.10  [Refereed]

     View Summary

    In this study, a hydrogen–air premixed flame in a partially tapered swirl burner in which a stable counterflow of unburned and burned gases is expected to be formed, was investigated. The experimental results indicate the formation of almost steady flames at equivalence ratios of as lean as 0.084, and the resulting ultra-lean flames in the swirling flow had a comet shape. Furthermore, the flame was numerically reproduced, and the mechanisms behind the phenomenon were identified by checking the balance among the chemical enthalpy through diffusion, heat flux by conduction, and transport of these parameters by convection. It was determined that the region around the tip of the flame head was almost dominated only by diffusion and heat conduction similar to a flame ball, but its formation mechanism was found to be essentially different from that of a flame ball because the comet-like flame can be numerically reproduced even without a radiative heat loss, in contrast to a flame ball.

    Dynamics and Design Conference : D & D   2014   "208 - 1"-"208-12"  2014.08

     View Summary

    In this study, characteristics of combustion oscillation generated in gas turbine combustor are numerically and experimentally investigated. Numerical analyses are performed with two different methods: Combined EBU method and Comparison PDF Transport method. These numerical results provide important parameters such as delay time. Stability criterion for combustion oscillation is evaluated by the combination of numerical analysis technique and the evaluation formula proposed by Z. M. Ibrahim. Experimental conditions are selected to investigate the condition of combustion oscillation excitation mechanism by changing experimental parameter such as composition of the fuel, equivalence ratios and swirl numbers. As a result, with increasing the rate of hydrogen in fuel or the swirl numbers, combustion oscillation is likely to occur and combustion oscillation occur under the conditions of specific equivalence ratios in the experiment. Finally, experimental results are compared with numerical analyses. A trend of natural frequency to the change of equivalence ratio and the range of equivalence ratios which combustion oscillation occurs by the numerical analysis is in good agreement with those by the experiment.

     View Summary

    <p>To reduce carbon dioxide emissions, ZEB (Net Zero Energy Building), which aims to promote energy saving in buildings, has attracted attention. Particularly, solar cooling systems that use solar radiation as renewable energy for ZEB are an effective heat source. However solar cooling systems have not become widespread. Therefore, it is necessary to clarify the methodology to design and operate equipments in ZEB with solar cooling systems. In this study, a two-step design process of equipments including solar cooling system was proposed. First, optimizations of configuration of the equipments including an adsorption chiller using solar heat as a heat source is performed using a mathematical model. Then, TRNSYS simulations are performed using the optimization results to derive the operation of the equipments against air conditioning load. Applying the proposed method to a hospital of 5,000 m2 , the optimal configuration of the equipments was obtained minimizing the annual cost. Then, the results of the equipment operation analysis showed that the primary energy consumption could reduce by 43% for the building with a solar cooling system than that without a solar cooling system.</p>

  • A prediction model of mechanical loss in a turbocharger considering oil temperature distribution of bearing

     View Summary

    <p>Recently, the downsizing turbo is widespreading to satisfy the emission regulations of automobiles. It is necessary to develop the model to predict the mechanical loss in a turbocharger in the model-based development. In our previous research, a mathematical model with the mechanical loss caused by the bearings used in a turbocharger was developed. In the previous model, the friction loss is estimated by lubricant temperature, lubricant flow, thrust force and rotation of the turbocharger. The lubricant temperature applied in the previous model was the average temperature of the inlet and the outlet. However, the inner lubricant temperature is higher than the outer lubricant temperature in the journal bearing, then it is inappropriate to apply the average temperature. This research aimed to improve the accuracy of the previous model adding the prediction model of the lubricant temperature distribution in the journal bearing. We estimated the lubricant temperature distribution in the journal bearing by calculating the Reynolds equation and energy equation iteratively. The result revealed that the lubricant temperature distribution in the axis direction, and the predicted value came closer to the measured value than the previous model in case the supply lubricant temperature is low.</p>

  • Effects of changes in temperature distribution in a tube simulating a combustor on the acoustic impedance

     View Summary

    <p>The previous studies to examine the influence of the fuel composition on combustion oscillation suggested that changes in combustion characteristics due to changes in fuel compositions, that is, hydrogen-containing ratio with city gas, influenced the acoustic boundary conditions on the upstream end of the combustor. To examine this suggestion, an experimental apparatus of a Rijke tube was manufactured, which is simulating a combustor of a gas turbine. Using this Rijke tube, the acoustic impedance was calculated by the two sensor method using experimentally-measured sound pressures. The result confirmed that the peak of absolute value of the acoustic impedance as the acoustic boundary condition shifted to higher frequency region due to high temperature distributions in the tube. However, in the previous study, the assumed temperature distributions were too simple. Therefore, in this study, we focused on the influence of a realistic temperature distribution along center-axis in the tube. To measure the temperature distribution in the tube, a new Rijke tube with 13 thermocouples were manufactured and the axis temperature distributions were obtained by the linearlyinterpolated measured temperatures. As a result, the calculated acoustic impedance almost corresponded to the previous method but the additional peak of the absolute value was found.</p>

     View Summary

    <p>It is necessary to know the parameters of the heat exchangers such as condenser, evaporator and adsorbent beds implemented in an adsorption chiller in order to evaluate its performance by numerical simulations. The parameters are UA-value and thermal capacity. However, these values are not available generally for actual appliances. The objective of this study is to estimate the parameters based on the numerical simulations. The outlet temperature of the plant is compared with the simulated one, which defference is fed back to adjust the estimated parameter with iterations. The study investigated the performance of the estimation procedure and found that the estimated parameters converged to the true values. The results show that the 4 parameters of condenser and evaporator can be estimated simultaneously.</p>

     View Summary

    © ECOS 2020.All right reserved. Since electric vehicles (EV) have large capacities, EVs are expected to be home battery devices if they work with Vehicle-to-Home (V2H) to store photovoltaic (PV) surplus power. To design energy systems for residential areas including EV, V2H, and PV, it is essential to know the features of houses which can expect the benefit of V2H. The objective of this paper is to analyze the potential of installing V2H at each house level considering the variation of power demand and the EV absence schedule. First, mathematical models of the energy system were formulated to optimize equipment configurations or capacities, and their operation. Then, the sensitivity analysis on the price of V2H device was conducted to estimate the competitive price of V2H. Moreover, the effects of the maximum capacity of PV were also considered in the analysis. The results showed that households with higher power demand or the larger capacity of PV had a higher potential of installing V2H. Furthermore, the EV absence time had a greater impact on the installation of V2H when the power demand was lower, or the capacity of PV was larger.
