Economic dispatch (ED) is considered to be one of the
\r\nkey functions in electric power system operation. This paper presents
\r\na new hybrid approach based genetic algorithm (GA) to economic
\r\ndispatch problems. GA is most commonly used optimizing algorithm
\r\npredicated on principal of natural evolution. Utilization of chaotic
\r\nqueue with GA generates several neighborhoods of near optimal
\r\nsolutions to keep solution variation. It could avoid the search process
\r\nfrom becoming pre-mature. For the objective of chaotic queue
\r\ngeneration, utilization of tent equation as opposed to logistic equation
\r\nresults in improvement of iterative speed. The results of the proposed
\r\napproach were compared in terms of fuel cost, with existing
\r\ndifferential evolution and other methods in literature.<\/p>\r\n","references":"[1] D. Liu, Y.
