Generator maintenance scheduling considering air pollution based on the fuzzy theory

A new technique using a search method which is based on fuzzy multicriteria function is proposed for generator maintenance scheduling, considering the air pollution. Not only minimization of probabilistic production cost and maximization of system reliability level but also air pollution are considered for fuzzy multicriteria function. To obtain an optimal solution for generator maintenance scheduling under fuzzy environment, fuzzy multicriteria relaxation method (fuzzy search method) is used. The practicality and effectiveness of the proposed approach are demonstrated by simulation studies for a real size power system model.
