基于纵横交叉算法的波浪发电装置最大功率跟踪控制
Maximum power point tracking control based on crisscross optimization algorithm for wave power generation
In wave energy maximum power point tracking control, a local optimal problem exists in traditional genetic algorithm and particle swarm optimization algorithm, thus a novel control strategy was proposed based on crisscross optimization algorithm(CSO). Under the judgment of vertical crossover probability, the arithmetic crossover algorithms between the individual dimension variables were implemented with the vertical crossover operator of CSO to ensure that the population would avoid the local optimum state. The random pairing and arithmetic crossover algorithms between individuals were completed, and the entire solution space was divided into several subspaces with the horizontal crossover operator of CSO. The pairing individuals were taken as the diagonal vertices of each subspace to attain perfect local search capability by searching the subspaces interior and its neighborhoods. Any information contributed to achieving global optimality was rapidly distributed among the variables of the population to change the search path by the alternation of the crisscross operators.The simulation results indicate that as wave period changes, the maximum power point tracking control can be achieved and the convergence speed can be improved with the CSO.
