    A comprehensive scheme for reliability-centered maintenance in power distribution systems - Part II: numerical analysis

    , Article IEEE Transactions on Power Delivery ; Volume 28, Issue 2 , 2013 , Pages 771-778 ; 08858977 (ISSN) Dehghanian, P ; Fotuhi Firuzabad, M ; Aminifar, F ; Billinton, R ; Sharif University of Technology
    Abstract
    The aim of this two-part paper is to present a comprehensive reliability-centerd maintenance framework tailored to power distribution systems. The first paper discusses the fundamental concepts, presents the developed algorithm, and introduces the required mathematical formulations. This second paper is focused on the application of the proposed methodology on a real distribution system. Considerable effort is devoted to examine the proposed method in a step-by-step manner to clarify the implementation procedure. The required data for the procedure are taken from available references and follow reasonable technical assumptions. Practical aspects are incorporated, and the results obtained are... 

    A comprehensive scheme for reliability centered maintenance in power distribution systems - Part I: methodology

    , Article IEEE Transactions on Power Delivery ; Volume 28, Issue 2 , 2013 , Pages 761-770 ; 08858977 (ISSN) Dehghanian, P ; Fotuhi Firuzabad, M ; Aminifar, F ; Billinton, R ; Sharif University of Technology
    Abstract
    Although reliability-centered maintenance (RCM) has proven its noticeable merits in many industries, has not been yet furnished with efficient analytical methods in the power engineering context. The first of this two-paper set presents a practical framework by which the RCM procedure can be implemented in power distribution systems. The proposed algorithm consists of three main stages. The prerequisites of the analysis are outlined in the first stage. In the second stage, an approach is developed to identify the network's critical components, from the reliability point of view. Having practically modeled the components' failure rates, an efficient cost/benefit evaluation approach is then... 

    Identification of critical components in power systems: A game theory application

    , Article 52nd Annual Meeting on IEEE Industry Application Society, 2 October 2016 through 6 October 2016 ; 2016 ; 9781467386715 (ISBN) Pourahmadi, F ; Fotuhi Firuzabad, M ; Dehghanian, P ; Sharif University of Technology

    Abstract
    As the electricity market undergoes continuous evolutions, along with the outdated nature of the grid, system operators would have to be able to more effectively manage the operation costs since waves of maintenance costs and equipment investments would be anticipated in the years to come. Strategic implementation of cost-effective reliability centered maintenance (RCM) approaches seems to be a key solution. This paper proposes an efficient method to assess the component criticality for the system overall reliability and further maintenance focuses. A solution concept of game theory, called Shapely Value, that is able to fairly identify the contribution of each single equipment to the system... 

    Application of game theory in reliability-centered maintenance of electric power systems

    , Article IEEE Transactions on Industry Applications ; Volume 53, Issue 2 , 2017 , Pages 936-946 ; 00939994 (ISSN) Pourahmadi, F ; Fotuhi Firuzabad, M ; Dehghanian, P ; Sharif University of Technology
    Abstract
    As the electricity market undergoes continuous evolutions, along with the widely-recognized outdated nature of the grid, system operators would have to be able to more effectively manage the system operation expenses since waves of maintenance costs and equipment investments would be anticipated in a few years to come. Strategic implementation of cost-effective reliability-centered maintenance (RCM) approaches seems to be a key solution. This paper proposes an efficient method to assess the component criticality for system overall reliability and further maintenance focuses. A solution concept of game theory, called shapely value, is proposed that is able to fairly identify the contribution... 

    A new multiattribute decision making support tool for identifying critical components in power transmission systems

    , Article IEEE Systems Journal ; Volume 12, Issue 1 , 2018 , Pages 316-327 ; 19328184 (ISSN) Gharakheili, M. A ; Fotuhi Firuzabad, M ; Dehghanian, P ; Sharif University of Technology

    Abstract
    The present context of the electric industry, characterized by competitive markets, privatization, and regulatory of technical requirements forces the power utilities to optimize their asset management practices and develop the requisite decision plans techno-economically. Practically approaching, this paper devises a new support tool based on a multiattribute decision making (MADM) framework in combination with analytical hierarchical process (AHP) to determine the most critical components of power transmission systems. Measure of system-wide reliability performance, outage cost, marginal clearing prices demonstrative of market fairness, and network losses are among the attributes... 

    Critical component identification in reliability centered asset management of power distribution systems via fuzzy AHP

    , Article IEEE Systems Journal ; Vol. 6, issue. 4 , 2012 , p. 593-602 ; ISSN: 19328184 Dehghanian, P ; Fotuhi-Firuzabad, M ; Bagheri-Shouraki, S ; Razi Kazemi, A. A ; Sharif University of Technology
    Abstract
    Confronted with the power system restructuring trend reforming the past-regulated power systems, the need for a narrower insight on the costly maintenance strategies seems imperative. It falls within the realm of reliability centered maintenance to enhance the cost effectiveness of power distribution maintenance policies. From a practical point of view, this paper devises a novel approach on the basis of the analytical hierarchical process (AHP) accompanied by fuzzy sets theory to determine the most critical component types of distribution power systems to be prioritized in maintenance scheduling. In the presence of many qualitative and quantitative attributes, fuzzy sets can effectively...
