Research on MPPT Based on Gray Wolf Algorithm improved by Levy Flight [PDF]

Journal of Physics: Conference Series, 2021
Abstract In the late iteration of the gray wolf algorithm, the convergence results will have low accuracy becased of the elite retention.When implementing MPPT control, the maximum power point of the photovoltaic array cannot be accurately tracked, and it is easy to fall into the local optimum.
