Fuzzy linear programming based optimal power system rescheduling includingpreventive redispatch

The paper presents an interactive fuzzy satisfying method for solving optim al power system rescheduling by assuming that the decision-maker has imprec ise or fuzzy goals and constraints. An interactive decision-making process is formulated in which decision-maker can learn to recognize good solutions by considering all possibilities of fuzziness, The salient features of the proposed method are: (i) ability of solving multi-objective problem which guaranties that a global noninferior solution will be generated; (ii) possi bility to obtain a reasonable nonfuzzy solution under consideration of the ambiguity of parameters.
