ECONOMIC LOAD DISPATCH USING SIMULATED ANNEALING ALGORITHM

Economic load dispatch is the process of allocating the required load demand between the available generating units such that the cost of operation is minimized. There have been many algorithms proposed for economic dispatch such as genetic algorithm, particle swarm optimization, and differential evolution. Out of which a simulated annealing (SA) was found to be one of the best methods that is discussed in this paper. Simulated Annealing (SA) algorithm for optimization inspired by the process of annealing in thermodynamics to solve economic load dispatch (ELD) problems. The proposed approach is found to provide the optimal results while working with operating constraints in the ELD and valve point loading effects. In this paper the efficiency for the three (3) generators and forty (40) generators is tested by MAT Lab coding. Also it is further extended for fifty (50) generators.
