[IEEE 2018 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia) - Singapore (2018.5.22-2018.5.25)] 2018 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia) - Spatial Data-Based Techno-economic Evaluation of Solar Hydrogen Production in the Middle East and North Africa (MENA) Region
摘要： The Middle East and North Africa (MENA) region is endowed with solar energy that can be harvested and stored as hydrogen, which has gained increasing focus as a secondary energy medium. This paper introduces modeling and feasibility analysis of cost-optimized hydrogen production, storage, shipment, and methanation in the MENA region. The analysis is based on the economic modeling of hydrogen production through the combination of photovoltaic solar power and electrolysis systems, utilizing NASA surface Meteorology and Solar Energy database (2010)[1]. A system of 100MW grid-connected photovoltaic PV power plant (grid-PV) in combination with hydrogen producing electrolyzer are simulated using spatial data for the MENA region. Then, the simulation assesses cost of methane production by Sabatier synthesis of carbon dioxide. The unit cost of hydrogen from a system, which consists of 100MW PV solar plant and electrolyzer, ranged 4-8 US$/kg. Methanation was found to be expensive vis-à-vis regionally traded natural gas. Location is a major determinant to hydrogen cost due to the difference in irradiation and logistics. In conclusion, this paper can serve as an atlas for mapping the cost of solar power and hydrogen production in the MENA region, and facilitates further research in the future.

Comparison and Identification of Suitable Multi-Response Optimization Technique for Laser Welding Process Parameters
摘要： In the present research work, comparison of four different multi-response optimization techniques viz., multi-response signal-to-noise ratio (MRSN), weighted signal-to-noise ratio (WSN), grey relational grade analysis (GRA) and the technique for order preference by similarity to ideal solution method (TOPSIS) have been applied in a case study of laser welding process for joining automotive gears of 16MnCr5 Alloy Steel. It has been observed that (MRSN) method gives the closest results and can be considered as the best suitable method for this case. The authors conclude that this approach could be applicable for any manufacturing application.

Optimization Of Process Mean Setting For CO2Laser Welding Process For Alloy Steel Automotive Gears With Application Of Taguchi Loss Function And Fraction Defective Method
摘要： In the present research work, authors suggest a fundamental approach for estimation of optimum process mean setting through the trade-off between cost of manufacturing (power cost) and internal quality loss to the manufacturer for CO2 laser welding process which is successfully applied for joining automotive gears of 16MnCr5 alloy steel and the process mean has been optimized subsequently. Two different approaches viz., the application of Taguchi quadratic loss function and fraction defective method have been used and compared for assessment of internal quality loss to the manufacturer. It is concluded that this approach can be applicable for any manufacturing situation.
