Abstract:In order to solve siting and sizing of distributed generation, the firefly algorithm based on adaptive genetics mechanism is presented. Firstly, regarding each node voltage, accessible maximum power, and line currents as constraints, the distribution network’s minimum loss as objective function, designing the optimization model of distribution network; Secondly, the improved firefly algorithm is presented, adding to improved crossover and mutation operations of genetic algorithm and improved Gauss perturbation, improves the global optimization ability and the convergence speed. Finally, experiments are conducted on IEEE33 node by means of MATLAB . Compared with the adaptive genetic algorithm, the results show that the improved algorithm is effective and superior. |
