    Reliability-based selection of wind turbines for large-scale wind farms

    , Article World Academy of Science, Engineering and Technology ; Volume 37 , 2009 , Pages 734-740 ; 2010376X (ISSN) Fotuhi Firuzabad, M ; Salehi Dobakhshari, A ; Sharif University of Technology
    This paper presents a reliability-based approach to select appropriate wind turbine types for a wind farm considering site-specific wind speed patterns. An actual wind farm in the northern region of Iran with the wind speed registration of one year is studied in this paper. An analytic approach based on total probability theorem is utilized in this paper to model the probabilistic behavior of both turbines' availability and wind speed. Well-known probabilistic reliability indices such as loss of load expectation (LOLE), expected energy not supplied (EENS) and incremental peak load carrying capability (IPLCC) for wind power integration in the Roy Billinton Test System (RBTS) are examined. The... 

    Effect of interline power flow controller (IPFC) on interconnected power systems adequacy

    , Article 2008 IEEE 2nd International Power and Energy Conference, PECon 2008, Johor Baharu, 1 December 2008 through 3 December 2008 ; 2008 , Pages 1358-1363 ; 9781424424054 (ISBN) Aminifar, F ; Fotuhi Firuzabad, M ; Nasiri, R ; Khodaei, A ; Sharif University of Technology
    This paper probes the impact of utilizing an IPFC on the reliability indices of interconnected power systems. First, a concise presentation of IPFC and its structure are provided and the reliability model of two unequally-rated parallel transmission lines equipped with IPFC is then extracted. The assumed IPFC is composed from two parallel converting bridges associated with each line. Afterwards, based-on equivalent assisting unit approach, different commonly-used adequacy indices including the loss of load expectation (LOLE), loss of energy expectation (LOEE) and system minutes (SM) are calculated. A set of numerical analyses are conducted to illustrate the sensitivity of these indices with...
