A simulation model for reliability-based appraisal of an energy policy: The case of Lebanon
No full textThe Lebanese Electric Power System (LEPS) has been suffering from technical and financial deficiencies for decades and mirrors the problems encountered in many developing countries suffering from inadequate or no power systems planning resulting in incomplete and ill-operating infrastructure, and suffering from effects of political instability, huge debts, unavailability of financing desired projects and inefficiency in operation. The upgrade and development of the system necessitate the adoption of a comprehensive energy policy that introduces solutions to a diversity of problems addressing the technical, financial, administrative and governance aspects of the system. In this paper, an energy policy for Lebanon is proposed and evaluated based on integration between energy modeling and financial modeling. The paper utilizes the Load Modification Technique (LMT) as a probabilistic tool to assess the impact of policy implementation on energy production, overall cost, technical-commercial losses and reliability. Scenarios reflecting implementation of policy projects are assessed and their impacts are compared with business-as-usual scenarios which assume no new investment is to take place in the sector. Conclusions are drawn on the usefulness of the proposed evaluation methodology and the effectiveness of the adopted energy policy for Lebanon and other developing countries suffering from similar power system problems. © 2012 Elsevier Ltd.Abi Said C., 2005, ELECT ENERGY ENERGY; Al-Shaalan A.M., 2011, J KING SAUD U ENG SC, V23, P27; Avetisyan M, 2006, ENERG ECON, V28, P455, DOI 10.1016-j.eneco.2005.12.001; Badelt G, 2000, ENERG POLICY, V28, P39, DOI 10.1016-S0301-4215(99)00085-3; BILLINTON R, 1978, IEEE T POWER AP SYST, V97, P2076, DOI 10.1109-TPAS.1978.354711; Billinton R, 1996, RELIABILITY EVALUATI; D'Sa A, 2005, ENERG POLICY, V33, P1271, DOI 10.1016-j.enpol.2003.12.003; Electricite du France, 2009, GEN TRANS MAST PLAN; El-Fadel M, 2003, RENEW ENERG, V28, P1257, DOI 10.1016-S0960-1481(02)00229-X; El-Fadel R.H., 2009, ENERG POLICY, V38, P751; Ghajar R., 2011, P 8 INT C EUR EN MAR; Hamdan H.A., 2010, THESIS LEB AM U BYBL; IEEE Reliability Test System, 1979, IEEE T POWER APPARAT, V98, P2047; Karaki SH, 2002, INT J ELEC POWER, V24, P611, DOI 10.1016-S0142-0615(01)00075-8; Ministry of Energy and Water, 2003, IPP EN PROJ EN POL S; Ministry of Energy and Water, 2010, POL PAP EL SECT; Ministry of Energy and Water, 2009, FORM MED LONG TERM F; Ministry of Energy and Water, 2005, IPP EN PROJ EN POL S; Ministry of Energy and Water, 2004, IPP EN PROJ BLUEP ES; World Bank, 2008, 41421LB WORLD BANK33
The Journey That Saved Curious George: The True Wartime Escape of Margret and H.A. Rey
No full textMany years ago, two Jewish artists from Germany met in Brazil, started a business, fell in love, and got married. The Brazilians could not pronounce their German names, so the couple shortened them to H.A. and Margret Rey. While honeymooning in Europe, the Reys decided to stay in Paris so H.A. could pursue a career as a children\u27s book author and illustrator. During this time, H.A. started developing stories about a curious little monkey, influenced by the many monkeys he saw in Brazil. But Hitler\u27s forces delayed H.A.\u27s plans for the little monkey until he and Margret could safely escape Europe
Out and All About: Fables for Old and Young
No full textThe title-page is missing in this book, and the only reference on the web is to a reprint of a book before 1923. At least this reference gives us an author. “Routledge” appears on the spine. I read only the first fable, “The Spider and the Ants,” which lasted some 20 pages and seemed to me to lose some of its focus along the way. The book is generously illustrated with partial-page black-and-white illustrations of various sizes along the way. As the beginning T of C shows, there are here some 31 fables on 256 pages before 18 pages of advertisements. Pretty cover and spine, including gold and black on red cloth.H.A. Pag

BCIT integrated grid laboratory planning framework
No full textThis paper presents a planning framework for an educational training facility designed to incorporate exposure to equipment and scenarios seen in modern power systems, such as islanded microgrids, distributed renewable generation, and new information and communications technologies. The overall architecture is geared towards addressing skills and training gaps in undergraduate “power systems” education. The design principles make this laboratory safe, robust, scalable, modular, and expandable and can therefore also be considered for transport to remote sites for training or demonstration purposes. The framework is based on development and implementation of such a facility at the British Columbia Institute of Technology (BCIT) in the Vancouver area of Canada. It is the goal of the author to allow other institutes to reduce overall implementation time and to share and collaborate on educational materials and pedagogical results. The paper concludes with the presentation of a cost function which ranks, according to the author and BCIT's planning experience, the relative costs and benefits for such a facility in comparison with other possible approaches
