    Application of Markov decision process in generating units maintenance scheduling

    , Article 2006 9th International Conference on Probabilistic Methods Applied to Power Systems, PMAPS, Stockholm, 11 June 2006 through 15 June 2006 ; 2006 ; 9171783520 (ISBN); 9789171783523 (ISBN) Rajabi Ghahnavie, A ; Fotuhi Firuzabad, M ; Sharif University of Technology
    An important issue in power system planning is maintenance scheduling of generating units. In a traditional power system, the problem of maintenance scheduling is of high importance and has various technical and economical constraints. Different methods have been used to solve the problem. On the other hand, changes in legal environment of electricity industry poses new bound and requirements on the maintenance scheduling problem. This paper presents a new approach on maintenance scheduling of generating units in a generating company (GENCO). The proposed approach uses Markov Decision Process (MDP) to minimize total costs of unserved energy and reserve. The impacts on maintenance scheduling... 

    A heuristic trade off model for integration of distributed generations in deregulated power systems considering technical, economical and environmental issues

    , Article 2008 IEEE 2nd International Power and Energy Conference, PECon 2008, Johor Baharu, 1 December 2008 through 3 December 2008 ; 2008 , Pages 1275-1279 ; 9781424424054 (ISBN) Hekmati, A ; Nasiri, R ; Bagheri, M ; Tehrani, A. A ; Sharif University of Technology
    With the introduction of restructuring concepts to traditional power systems, a great deal of attention is given to the utilization of distributed generation. Since the integration of DG units has been known as an alternative for main grid as a resource for energy supply, the determination of optimal sizing and sitting is an important issue in the planning procedure of DG. This work presents a comprehensive multi-objective model for integration of distributed generations into a distribution network, regarding various technical, economical and environmental issues such as reduction of carbon dioxide emissions and investment & running costs while the bus voltages shall be kept within...
