a nash approach to planning merchant transmission for Renewable Resource integration
Research Papers in Economics, 2013Co-Authors: Qun Zhou, Ron F. Chu, Leigh Tesfatsion, Chen-ching Liu, Wei SunAbstract:Major transmission projects are needed to integrate and to deliver Renewable energy (RE) Resources. Cost recovery is a serious impediment to transmission investment. A negotiation methodology is developed in this study to guide transmission investment for RE integration. Built on Nash bargaining theory, the methodology models a negotiation between an RE generation company and a transmission company for the cost sharing and recovery of a new transmission line permitting delivery of RE to the grid. Findings from a six-bus test case suggest that RE subsidies can be effectively used to achieve system optimality when RE prices are fixed through bilateral contracts but have limited ability to achieve system optimality when RE prices are determined through locational marginal pricing. This limitation needs to be recognized in the design of RE subsidies.

Hence, the approach could potentially be used as a guideline for RE investors. The study also discusses the possibility of using RE subsidies to steer the negotiated solution towards a system-optimal transmission plan that maximizes total net benefits for all market participants. The findings suggest that RE subsidies can be effectively used to achieve system optimality when RE prices are fixed through bilateral contracts but have limited ability to achieve system optimality when RE prices are determined through locational marginal pricing.

chemical modification of natural rubber in the latex stage by grafting cardanol a waste from the cashew industry and a Renewable Resource
Industrial & Engineering Chemistry Research, 2013Co-Authors: S C Mohapatra, G B NandoAbstract:Cardanol, an agricultural byproduct of the cashew industry, is a cheap and abundantly available Renewable Resource. The multifunctional activity of cardanol in the rubber and polymer industries has been well-established in recent years. The present study highlights the chemical grafting of cardanol onto natural rubber in the latex stage. The cardanol grafted natural rubber is characterized by FTIR and NMR spectroscopies. The grafting parameters have been optimized for maximum yield in terms of percent grafting and grafting efficiency by the Taguchi method. Four control factors, i.e., initiator concentration, cardanol concentration, reaction temperature, and reaction time, are chosen at three different levels. The optimum parameter combination is found to be the initiator concentration 2 phr, cardanol concentration 10 phr, reaction temperature 65 °C, and reaction time 6 h. The analysis of variance method is used to evaluate the percentage contributions of the different control factors on the percent grafti...

synthesis and characterization of polymers from cashewnut shell liquid cnsl a Renewable Resource ii synthesis of polyurethanes
European Polymer Journal, 1999Co-Authors: Haripada Bhunia, Amit Basak, G B Nando, T K Chaki, Subasini Lenka, Padma L NayakAbstract:Abstract A novel copolyester was synthesized by solution polycondensation of terephthaloyl chloride with 4-[(4-hydroxy-2-pentadecenylphenyl)diazenyl] phenol (HPPDP) and 1,4-butane diol. The monomer (HPPDP) has been synthesized from 3-pentadecenyl phenol, a Renewable Resource and a by-product of the cashew industry characterized earlier [1] . The copolyester was characterized through elemental analysis, 1 H -NMR, IR, and UV spectroscopy. Dilute solution viscosity of its solution was also determined by viscometry. The intrinsic viscosity [η] was 0.98 dl/gm. The melting temperatures of the copolyester were 63 and 127°C as observed from Differential Scanning Calorimetric (DSC) studies. Thermogravimetric analysis show that degradation commences at 290°C in nitrogen atmosphere. Wide-angle X-ray diffraction study of the copolyester indicates absence of any crystallinity, whereas DSC studies indicate the presence of two melting peaks. Thus, it is presumed that the copolyester has short range crystallinity.

synthesis of polyurethane from cashew nut shell liquid cnsl a Renewable Resource
Journal of Polymer Science Part A, 1998Co-Authors: Haripada Bhunia, Amit Basak, Subasini Lenka, R N Jana, G B NandoAbstract:A novel thermoplastic polyurethane was prepared from cardanol, a Renewable Resource and a waste of the cashew industry. Cardanol was recovered from cashew nut shell liquid (CNSL) by double vacuum distillation. It was characterized by CHN analysis and IR, 1H-NMR, and 13C-NMR spectroscopy techniques. Cardanol is a meta-substituted long chain phenol. The long aliphatic chain unit substituent was found to be a monoene. The monomer, 4-[(4-hydroxy-2-pentadecenylphenyl)diazenyl]phenol was prepared from cardanol. It was a dihydroxy compound as characterized by CHN analyzer, UV, and 1H-NMR spectroscopy. The polyurethane was synthesized from this dihydroxy compound by the treatment with 4,4′-diphenylmethane diisocyanate (MDI) in dimethylformamide (DMF) solvent at 80–90°C under nitrogen atmosphere. The polymer was characterized by 1H-NMR, FTIR, and UV spectroscopy. The elemental analysis was done for determining the percentage content of C, H, and N, and the intrinsic viscosity [η] of polymer showed 1.85 dL/gm. Thermogravimetric investigations (TGA) of the cardanol, the dihydroxy compound, and the polyurethane were performed to study their decomposition. The semicrystalline nature of the PU was confirmed by differential scanning calorimetry (DSC) and dynamic mechanical thermal analyzer (DMTA). The wide-angle X-ray diffraction (WAXS) study of PU shew a broad amorphous halo indicative of absence of crystallinity in the polymer, which has been explained as due to strong hydrogen bonding in the hard phase. PU may possibly be useful as a telecommunication and as a nonlinear optical material. © 1998 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 36: 391–400, 1998

the survival of the conformist social pressure and Renewable Resource management
Journal of Theoretical Biology, 2012Co-Authors: Alessandro Tavoni, Maja Schluter, Simon A LevinAbstract:This paper examines the role of other-regarding behavior as a mechanism for the establishment and maintenance of cooperation in Resource use under variable social and environmental conditions. By coupling Resource stock dynamics with social dynamics concerning compliance to a social norm prescribing non-excessive Resource extraction in a common pool Resource, we show that when reputational considerations matter and a sufficient level of social stigma affects the violators of a norm, sustainable outcomes are achieved. We find large parameter regions where norm-observing and norm-violating types coexist, and analyze to what extent such coexistence depends on the environment.

the survival of the conformist social pressure and Renewable Resource management
Nota di Lavoro - Fondazione Eni Enrico Mattei (FEEM), 2010Co-Authors: Alessandro Tavoni, Maja Schluter, Simon A LevinAbstract:This paper examines the role of pro-social behavior as a mechanism for the establishment and maintenance of cooperation in Resource use under variable social and environmental conditions. By coupling Resource stock dynamics with social dynamics concerning compliance to a social norm prescribing non-excessive Resource extraction in a common pool Resource (CPR), we show that when reputational considerations matter and a sufficient level of social stigma affects the violators of a norm, sustainable outcomes are achieved. We find large parameter regions where norm-observing and norm-violating types coexist, and analyze to what extent such coexistence depends on the environment.
