    From loss allocation to loss cost allocation: a comparative study of different loss cost allocation methods

    , Article International Transactions on Electrical Energy Systems ; Volume 23, Issue 4 , 2013 , Pages 586-600 ; 20507038 (ISSN) Ghofrani Jahromi, Z ; Ehsan, M ; Fotuhi Firuzabad, M ; Parvania, M ; Sharif University of Technology
    As a high proportion of the total generated electricity energy and the power system costs is due to the power losses in lines, allocating the loss and associated cost to the system loads and generating units is a substantial issue in deregulated power systems. The procedure to accomplish this cost allocation is designated as 'loss cost allocation' (LCA). So far, a number of LCA methods have been proposed for transmission networks. A few papers have compared different loss allocation methods, which are the methods which calculate the loss (and not necessarily the loss cost) allocated to the loads and generating units. However, this paper presents a comparative study of LCA methods. In this... 

    Value-Based Reserve Cost Allocation to Participants of Power Market Based on Secure Load Condition

    , M.Sc. Thesis Sharif University of Technology Nazari, Mohammad Hassan (Author) ; Hosseini, Hamid (Supervisor)
    There are a lot of methods for the settlement of the reserve power market which can ultimately lead to a pattern of consumption and generation for each of the participants of the power market. After this step, however, justified and logical methods should be utilized for paying the reserving costs to the participants as in a long-term it can optimize the economic conditions of the market which can result in getting more realistic bidding from the participants. The current methods used for paying the reserving costs are mostly locational marginal prices and pay-as bid approach. By the same token, for receiving the reserving costs from the customers, some consider the desired reliability level... 

    Cost allocation under competition: a new rail access charging policy

    We consider a setting in which a rail infrastructure provider divides the track costs proportionally between the above-rail operators based on their usage. We study a proposed access charge regime aimed at incentivizing the operators to use longer train configurations. The regime sets a target length and gives a discount on an operator’s charge if it deploys a configuration of at least the target. That is, the operators may be able to reduce their access charges by deploying a longer train configuration. We analyze the policy, and conditions under which both operators have an incentive to deploy long train configurations. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature and EURO... 

    Customer choice of reliability in spinning reserve procurement and cost allocation

    , Article 2008 IEEE Electrical Power and Energy Conference - Energy Innovation, Vancouver, BC, 6 October 2008 through 7 October 2008 ; January , 2008 ; 9781424428953 (ISBN) Ahmadi Khatir, A ; Fotuhi Firuzabad, M ; Sharif University of Technology
    Reliability is one of the main factors influencing customer loyalty in a competitive power industry. The system operator must ensure that there is sufficient spinning reserve to maintain system security. Contractually such commodity requires a willing buyer and a willing seller. A novel pool-based market clearing algorithm for spinning reserve procurement and the cost allocation associated with provision of spinning reserve among DisCos is developed in this paper. Rational buyer model is used for energy and reserve market model. In the proposed algorithm, generating units bid simultaneously to energy and spinning reserve markets and these markets are sequentially cleared. In such a market,... 

    Dynamic Security Assessment in Restructured Power Systems

    , Ph.D. Dissertation Sharif University of Technology Kheradmandi, Morteza (Author) ; Ehsan, Mahdi (Supervisor)
    This thesis addresses the problem of dynamic security assessment in power sys-tems with an emphasis on its application in restructured power systems and issues arising in its applications. The new electric utility environment has an immedi-ate consequence of emphasis on reliability and secure operation of power systems. This requires faster and more precise methods to assess the dynamic aspect of se-curity. On the other hand, this issue is becoming challenging when the determined dispatch might not be accommodated due to violation of the limits.This thesis addresses the problem of dynamic security assessment in power sys-tems with an emphasis on its application in restructured power systems... 

    Customer choice of reliability in spinning reserve procurement and cost allocation using well-being analysis

    , Article Electric Power Systems Research ; Volume 79, Issue 10 , 2009 , Pages 1431-1440 ; 03787796 (ISSN) Ahmadi Khatir, A ; Fotuhi Firuzabad, M ; Goel, L ; Sharif University of Technology
    A novel pool-based market-clearing algorithm for spinning reserve (SR) procurement and the cost allocation associated with provision of spinning reserve among customers (DisCos) is developed in this paper. Rational buyer market model is used to clear energy and spinning reserve markets in the proposed algorithm. This market model gives DisCos the opportunity to declare their own energy requirement together with their desired reliability levels to the ISO and also they can participate in the SR market as a interruptible load. The DisCos' desired reliability levels are selected from a hybrid deterministic/probabilistic framework designated as the system well-being model. Using the demand of... 

    Simultaneous congestion management and cost allocation in a short-run market model

    , Article Iranian Journal of Science and Technology, Transaction B: Engineering ; Volume 31, Issue 6 , December , 2007 , Pages 617-628 ; 10286284 (ISSN) Fatahi Meyabadi, A ; Barati, H ; Ehsan, M ; Sharif University of Technology
    This paper proposes a simultaneous approach to manage congestion, evaluate congestion cost, and to allocate this cost among consumers in a short-run market model. The proposed method consists of an iterative algorithm to search and apply a sequence of the best feasible bilateral power exchange among the generators that would optimally reduce and completely remove the congestion. The best exchanges are selected using sensitivity analysis and the AC load flow is used to apply the selected exchange on the system. Congestion cost is calculated using the change in generation cost and divided among the overloaded lines regarding the change in power flow of these lines, after applying the selected... 

    Pricing of transmission services: An efficient analysis based on fixed and variable imposed costs

    , Article 2012 11th International Conference on Environment and Electrical Engineering, EEEIC 2012 - Conference Proceedings, 18 May 2012 through 25 May 2012, Venice ; 2012 , Pages 407-412 ; 9781457718281 (ISBN) Arabali, A ; Hosseini, S. H ; Moeini-Aghtaie, M ; Sharif University of Technology

    Open access to transmission networks as well as designing an efficient cost allocation method are the key points that provide free competition for participants in power market. Restructuring in power systems has created new challenges which emphasize the development and fairness of economical criteria such as pricing of different services in market environment. Besides, the charge of network usage is a controversial subject, itself. To address this problem, many methods for transmission line cost allocation have been proposed. Amongst them, MW-Mile methods are based on the extent of use concept. Inability to take various fixed together with variable imposed costs into account can be...
