基于GA的光伏MPPT变加速扰动法的研究
Research on MPPT of photovoltaic system by variable acceleration disturbance method based on Genetic Algorithm
The benefits of PV have limited its large-scale development. In order to improve the efficiency of photovoltaic power generation, an PV MPPT accelerating perturbation method based on genetic algorithm is proposed .The difference between the variable step and the accelerating perturbation method is compared, and the acceleration process of the variable perturbation method is verified by the mathematical formula. To further improve the tracking accuracy and reduce the tracking time of the system, the genetic algorithm is used to establish the initial search range. Finally, the simulation model is built in Matlab/ Simulink software platform, and the correctness of the method is verified by simulation.
