technical and economic potential of concentrating solar thermal power generation in india
Renewable & Sustainable Energy Reviews, 2017Co-Authors: Ishan Purohit, Pallav PurohitAbstract:This study aims to assess the technical and economic potential of concentrating solar power (CSP) generation in India. The potential of CSP systems is estimated on the basis of a detailed solar radiation and land resource assessment in 591 districts across the country. The land suitability, favorable solar resource conditions and wind power density over the vicinity have been considered key parameters for potential estimation. On the basis of a district-wise solar and land resource assessment, the technical potential of CSP systems is estimated over 1500 GW at an annual direct normal irradiance (DNI) over 1800 kWh/m2 and wind power density (WPD) ≥150 W/m2 after taking into accounts the viability of different CSP technologies and land suitability criteria. The economic potential of CSP is estimated at 571 GW at an annual DNI over 2000 kWh/m2 and WPD≥150 W/m2 in India. The technical evaluation of CSP technologies over the potential locations have been carried through System Advisor Model (SAM) Software using the Typical Meteorological Year data of Meteonorm 7.0 weather database. In near future, it is anticipated that locations with DNI values ≥1600–1800 kWh/m2 could also become economically feasible with the development of new technologies, advancement of materials, efficient and cost-effective thermal energy storage, economy of scale, Manufacturing Capability along with the enhanced policy measures, etc. In the long-term, it is possible to exploit over 2700 GW solar power through CSP in India with an annual DNI ≥1600 kWh/m2 and WPD≥150 W/m2. The findings of this study can be used for identification of niche areas for CSP projects in India.

evaluating the potential of concentrating solar power generation in northwestern india
Energy Policy, 2013Co-Authors: Ishan Purohit, Pallav Purohit, Shashaank ShekharAbstract:Abstract To accelerate the decarburization in the Indian power sector, concentrating solar power (CSP) needs to play an important role. CSP technologies have found significant space in the Jawaharlal Nehru National Solar Mission (JNNSM) of the Indian government in which 20,000 MW grid connected solar power projects have been targeted by 2022 with 50% capacity for CSP. In this study a preliminary attempt has been made to assess the potential of CSP generation in the Northwestern (NW) regions of India; which seems a high potential area as it has the highest annual solar radiation in India, favorable meteorological conditions for CSP and large amount of waste land. The potential of CSP systems in NW India is estimated on the basis of a detailed solar radiation and land resource assessment. The energy yield exercise has been carried out for the representative locations using System Advisor Model for four commercially available CSP technologies namely Parabolic Trough Collector (PTC), Central receiver system (CRS), Linear Fresnel Reflector (LFR) and Parabolic Dish System (PDS). The financial viability of CSP systems at different locations in NW India is also analyzed in this study. On the basis of a detailed solar radiation and land resource assessment, the maximum theoretical potential of CSP in NW India is estimated over 2000 GW taking into accounts the viability of different CSP technologies and land suitability criteria. The technical potential is estimated over 1700 GW at an annual direct normal incidence (DNI) over 1800 kW h/m 2 and finally, the economic potential is estimated over 700 GW at an annual DNI over 2000 kW h/m 2 in NW India. It is expected that in near future locations with lower DNI values could also become financially feasible with the development of new technologies, advancement of materials, economy of scale, Manufacturing Capability along with the enhanced policy measures etc. With an annual DNI over 1600 kW h/m 2 it is possible to exploit over 2000 GW CSP in the NW India.

techno economic evaluation of concentrating solar power generation in india
Energy Policy, 2010Co-Authors: Ishan Purohit, Pallav PurohitAbstract:Abstract The Jawaharlal Nehru National Solar Mission (JNNSM) of the recently announced National Action Plan on Climate Change (NAPCC) by the Government of India aims to promote the development and use of solar energy for power generation and other uses with the ultimate objective of making solar competitive with fossil-based energy options. The plan includes specific goals to (a) create an enabling policy framework for the deployment of 20,000 MW of solar power by 2022; (b) create favourable conditions for solar Manufacturing Capability, particularly solar thermal for indigenous production and market leadership; (c) promote programmes for off grid applications, reaching 1000 MW by 2017 and 2000 MW by 2022, (d) achieve 15 million m 2 solar thermal collector area by 2017 and 20 million by 2022, and (e) deploy 20 million solar lighting systems for rural areas by 2022. The installed capacity of grid interactive solar power projects were 6 MW until October 2009 that is far below from their respective potential. In this study, a preliminary attempt towards the technical and economic assessment of concentrating solar power (CSP) technologies in India has been made. To analyze the techno-economic feasibility of CSP technologies in Indian conditions two projects namely PS-10 (based on power tower technology) and ANDASOL-1 (based on parabolic trough collector technology) have been taken as reference cases for this study. These two systems have been simulated at several Indian locations. The preliminary results indicate that the use of CSP technologies in India make financial sense for the north-western part of the country (particularly in Rajasthan and Gujarat states). Moreover, internalization of secondary benefits of carbon trading under clean development mechanism of the Kyoto Protocol further improves the financial feasibility of CSP systems at other locations considered in this study. It may be noted that the locations blessed with annual direct solar radiation more than 1800 kWh/m 2 are best recommended for installation of CSP systems. The results obtained can be used as preliminary indicators for identifying niche areas for immediate/short-term utilization of solar energy for concentrating solar power generation in India.

key practices Manufacturing Capability and attainment of Manufacturing goals the perspective of project engineer to order Manufacturing
International Journal of Project Management, 2013Co-Authors: Li Ren YangAbstract:Abstract Project Manufacturing or engineer-to-order (ETO) Manufacturing is an operation designed to provide unique but similar products. For ETO Manufacturing, every product is the ultimate result of a project. In addition, unique orders may be managed like a project. The primary purpose of this study was to validate a model for assessing the relationships among Manufacturing practice, Manufacturing Capability, and attainment of Manufacturing goals from the perspective of project Manufacturing. The analyses suggest that implementation of Manufacturing practices in terms of production planning, quality management, human resource management, and capacity management may improve Manufacturing Capability. The results also imply that Manufacturing Capability may enhance attainment of project Manufacturing goals. Furthermore, the findings indicate that stability of supplier's Manufacturing acts as a moderator between Manufacturing practice and Manufacturing Capability. Finally, the positive association between Manufacturing Capability and attainment of project Manufacturing goals depends on process maturity, complexity, time availability, and team size.

Manufacturing Capability to improve project engineer to order Manufacturing performance
Advanced Materials Research, 2012Co-Authors: Li Ren YangAbstract:Project Manufacturing or engineer-to-order (ETO) Manufacturing is an operation designed to provide unique but similar products. It not only takes advantage of common Manufacturing requirements and efficiency, but also allow for customization into unique combinations. Unique orders may be managed like a Manufacturing project. However, many manufacturers do not adequately enhance Manufacturing Capability leading to a poor project Manufacturing performance. Thus, the primary purpose of this study was to assess the relationships between Manufacturing Capability and Manufacturing project performance. The results suggest that Manufacturing Capability can improve Manufacturing project performance. Furthermore, the positive association between Manufacturing Capability and Manufacturing project performance depends on process maturity, complexity, time availability, and team size.

knowledge stickiness in the buyer supplier knowledge transfer process the moderating effects of learning Capability and social embeddedness
Expert Systems With Applications, 2012Co-Authors: Chiaying LiAbstract:Increased outsourcing yields less vertically-integrated firms, suppliers have to rely on different buyers and interdisciplinary teams for acquired and utilized knowledge to improve performance. However, knowledge transfer from buyers to suppliers is not always successful. Studies pertaining to the knowledge stickiness between firms in the knowledge transfer process, such as between buyers and suppliers, have been minimal. Furthermore, while knowledge transfer processes are essentially context-specific in terms of who participates and how they participate in the process, it is very important to put knowledge transfer into context. The results provide support for a curvilinear inverted-U shape relationship between knowledge stickiness and Manufacturing Capability. In addition, the influence of knowledge stickiness on Manufacturing Capability would be enhanced by the moderating variables of social embeddedness and learning Capability. The finding further suggests that supplier Manufacturing capabilities impact supplier commitment and supplier performance.

neural network based manufacturability evaluation of free form machining
International Journal of Machine Tools & Manufacture, 2005Co-Authors: Marjan Korosec, Joze Balic, Janez KopacAbstract:Abstract Most CAD/CAM and computer-aided process planning systems manipulate all geometrical features on the part equally. In the area of free form machining, lack of efficient methodology for assessing the degree of Manufacturing pretentiousness of free form features is still noticeable. Developing this methodology inside CAD/CAM systems brings the following benefits to the tool shop praxis: it minimizes the number of set-ups and tool changes and at the same time ensures the right sequence of machining strategies in order to achieve the best possible surface quality in the machining area. Based on this assessment, the CAD/CAM process will also be greatly simplified. When there are an increased number of non-prismatic and non-cylindrical features, this problem is even more exaggerated, and its solution cannot be found in the framework of analytical mathematics. This paper reports a neuro-fuzzy model that uses the concept of “feature manufacturability” to identify and recognize the degree of “pretentiousness—difficulty of machining”. The model is created by means of the construction of parametric fuzzy membership functions, based on neural networks learning process. This makes possible simultaneous evaluation of features complexity in a CAD model and Manufacturing Capability in an environment description model.
