GENETIC ALGORITHM SOLUTION OF ECONOMIC-DISPATCH WITH VALVE POINT LOADING

A genetics-based algorithm is used to solve an economic dispatch problem for valve point discontinuities. The algorithm utilizes payoff information of candidate solutions to evaluate their optimality. Thus, the constraints of classical LaGrangian techniques on unit curves are circumvented. The formulations of an economic dispatch computer program using genetic algoritluns are presented and the program's performance using two different encoding techniques is compared. The results are verified for a sample problem using a dynamic programming technique.
