Simulated Annealing Based Optimization for Solving Large Scale Economic Load Dispatch Problems

This paper presents a Simulated Annealing (SA) approach 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 proposed method works very fast, this aspect of algorithm is striking when applied for a large ELD system. Simulation has been performed over two different cases. Case study-I consist 38 generating units and Case study-II consist 110 generating units, both cases having convex fuel cost characteristics. The proposed method results have been compared with other relative existing approaches and finally SA proves luminous feasibility, robustness and fast convergence for optimization of ELD problems.
