This paper presents an efficient simulated annealing (SA) algorithm for solving economic load dispatch (ELD) problems in electrical power system. The objectives of ELD problems in electric power generation is to programmed the devoted generating unit outputs so as to meet the mandatory load demand at lowest amount operating cost while satisfying all units and system equality and inequality constraints. Global optimization approaches is inspired by annealing process of thermodynamics. The SA algorithm presented here is applied to two case studies, which analyze power systems having three, and six generating units. The results determined by SA algorithm are compared to those found by conventional quadratic programming (QP) and genetic algorithm (GA).
