    Technology planning system for the Iranian petroleum industry: lessons learned from sanctions

    , Article Technological Forecasting and Social Change ; Volume 122 , 2017 , Pages 170-178 ; 00401625 (ISSN) Hoshdar, F ; Ghazinoory, S ; Arasti, M ; Fassihi, S. F ; Sharif University of Technology
    Iran's petroleum industry is facing challenges including maturity of hydrocarbon fields, growing population of the nation that demands additional revenues from petroleum exports, and international economic sanctions that have limited access to technology sources. Restrictions from international technology providers have led managers of the industry enterprises to try to develop their needed technologies inside the country. The Ministry of Petroleum has supervised this and as a result, a technology planning systems has been developed and implemented since 2009. In this paper, an overview of the Iranian petroleum industry is provided from a technology planning perspective. The focus has been... 

    Optimal reactive power planning in harmonic distored power system using genetic algorithm

    , Article IEEE TENCON 2004 - 2004 IEEE Region 10 Conference: Analog and Digital Techniques in Electrical Engineering, Chiang Mai, 21 November 2004 through 24 November 2004 ; Volume C , 2004 , Pages C347-C350 Niknam, T ; Ranjbar, A .M ; Arabian, H ; Mirjafari, M ; Sharif University of Technology
    A continuous growth in nonlinear loads may cause an increment in harmonic distortion and some other important problems in power systems so considering power quality effects in optimal reactive power planning has become more crucial than before. In this paper, optimal reactive power planning based on voltage profile deviation and voltage THD decrement is studied. The planning problem is studied using reactive power injection in each bus bar and genetic algorithm is also used for solving optimization problem. Obtained results for 5-bus and 30-bus IEEE standard networks are also presented. ©2004IEEE
