  • Utility-scale implementable potential of wind and solar energies for Afghanistan using GIS multi-criteria decision analysis
    Renewable and Sustainable Energy Reviews, 2017
    Co-Authors: Mohammad Abed Anwarzai, Ken Nagasaka
    Abstract:

    Abstract The purpose of this research is to examine the available resources, quantify and introduce Multi-Criteria Decision Analysis (MCDA) and Geographical Information System (GIS) techniques for the wind and solar energies development. We analyzed the NREL data and selected the suitable sites selection criteria according to the resources, topography, environmental, and economic viewpoints. The GIS tools were used to apply the MCDA system for determining the implementable areas. Based on areas, we estimated the wind and solar power potential considering the technologies and site conditions. As a result, the total calculated potential of Annual Generation would be; 342,521 GWh wind energy, 140,982 GWh from solar PV, and about 6,000 GWh from CSP (Concentrating Solar Power) technologies that are 160 times of the existing power supply.

  • Potential evaluation and long-run installation scheduling of offshore wind power of entire Japan
    2012
    Co-Authors: Asifujiang Abudureyimu, Yoshiki Hayashi, Ken Nagasaka
    Abstract:

    The off-shore wind energy has been drawing interest recently. This research is focusing on the potential analysis of off-shore wind energy surrounding entire Japan coast using GIS technology. Base on the economy and environment assessment, this research is evaluating the current situation and forecasting on future of wind energy technology in Japan. In order to reduce the green-house gas emission, renewable energy (such as wind energy, solar energy, fuel cell…) will gradually substitute can be installed the primary energy resource (such as coal, oil, scale gas‥). Based on GIS technique, wind power turbines in the surrounding area of Japanese coast-line. In the study, 2000kW rated wind turbines are considered for further installation. As the result of this study, we have determined that 108,067 in 330 places number of off-shore with Annual Generation of 180.0TWhare expected. This is equal to 20% of Annual total generated power of Japan in 2011. In this study, after determination of potential evaluation of offshore wind power for the entire Japan, we have applied a well-know Dynamic Programming (DP) method to propose a plan of installation of the above determined number of offshore wind power units from year 2012 to 2030 respectively. As far as we know, there is no such scheduling for introducing offshore wind power in Japan.

  • parabolic trough solar power plant simulation model preprint
    2003
    Co-Authors: H Price
    Abstract:

    As interest for clean renewable electric power technologies grows, a number of parabolic trough power plants of various configurations are being considered for deployment around the globe. It is essential that plant designs be optimized for each specific application. The optimum design must consider the capital cost, operations and maintenance cost, Annual Generation, financial requirements, and time-of-use value of the power generated. Developers require the tools for evaluating tradeoffs between these various project elements. This paper provides an overview of a computer model that is being used by scientists and developers to evaluate the tradeoff between cost, performance, and economic parameters for parabolic trough solar power plant technologies. An example is included that shows how this model has been used for a thermal storage design optimization.

  • offshore wind power simulation by using wrf in the central coast of chile
    Renewable Energy, 2016
    Co-Authors: Cristian Mattar, Dager Borvaran
    Abstract:

    Abstract This paper presents the first estimate of offshore wind power potential for the central coast of Chile. For this purpose, wind speed data from in-situ stations and ERA-Interim reanalysis were used to simulate wind fields at regional level by means of the Weather Research and Forecasting (WRF) model. Wind field simulations were performed at different heights (20, 30, 40 and 140 m.a.s.l.) and a spatial resolution of 3 × 3 km for the period from February 1, 2006 to January 31, 2007, which comprised the entire series of in-situ data available. The results show an RMSE and r2 of 2.2 m s−1 and 0.55 respectively for the three heights simulated as compared to in-situ data. Based on the simulated wind data, the wind power for the study area was estimated at ∼1000 W m−2 at a height of 140 m.a.s.l. For a typical wind turbine of 8 MW generator, the estimated capacity factor exceeds 40%, with an average Annual Generation of ∼30 GWh. Offshore wind power in Chile is an emerging renewable energy source that is as yet still under-developed, these estimates help to fill in some of the gaps in our knowledge about Chile's true renewable energy potential.

  • Statewide plan for utilization of scrap tires in Kansas
    1995
    Co-Authors: R G Nelson, M Hossain
    Abstract:

    This study was conducted to determine the current and future supply of scrap tire rubber and the feasibility of using scrap tires in Kansas for various purposes. The goal was to determine if a sufficient quantity of recycled rubber existed and what the cost would be to meet the ISTEA (Intermodal Surface Transportation Efficiency Act) requirements for 1995 and thereafter. The four tasks included in the study were: surveying scrap tire utilization plans in other states; creating an inventory of scrap tires in Kansas; estimating scrap tire Generation in the future; and determining cost effectiveness of various uses of scrap tires. Currently there are 4.5 to 5.5 million scrap tires in Kansas and the Annual Generation of scrap tires is estimated to be 2 to 3 million, The ISTEA mandate would require an estimated 367,000 scrap tires be recycled Annually. KDOT has used more rubber in 1993 and 1994 than will be required by 1997 when the 20% required by ISTEA is in effect. The most energetically and economically feasible method of disposal of scrap tires is as a fuel substitute for coal or natural gas in a co-fired application or in a dedicated scrap tire-to energy facility. One of the cement producers in Kansas currently uses between 250,000 and 600,000 scrap tires Annually for fuel.
