Abstract


Of thermal power plant units economic dispatch optimization algorithm for unit commitment optimization of versatility , the combination of M units is abstracted into a each of a number from the array of the M and M number and equal to a given value of math problems . On this basis , proposed and implemented a new versatility to adapt to any change in the unit number of the unit combinatorial optimization exhaustive algorithm , analysis of the algorithm complexity . Backtracking exhaustive search of combinatorial optimization . By experiment to verify the correctness and completeness of the algorithm , and really search all possible solutions , when applied to the economic dispatch of the unit to be able to find the optimal solution . Backtracking method has the disadvantage is a long calculation time and only applicable to a few units . Application shuffled frog leaping algorithm to solve the unit commitment optimization problem explore . Proposed and implemented an equally versatile , able to adapt to any change in the unit number of the unit combinatorial optimization shuffled frog leaping algorithm analysis algorithm complexity . The algorithm has good global search and local update strategy . A comparative analysis of the experimental results of the two algorithms . With shuffled frog leaping algorithm to solve combinatorial optimization problems in the unit stability is poor , it can not guarantee that the get optimal solution shortcomings . When the number of units of the unit is less shuffled frog leaping algorithm computing time than backtracking . However, when the number of units of the unit more shuffled frog leaping algorithm the calculation time is significantly shorter than backtracking .
