ABSTRACT: In this paper, we have studied the different output characteristics having photovoltaic modules with partial shading of the modules, in this way we have adopted an approach that achieves an effective track of maximum power point. This approach is based on the optimization of particle swarming (PSO), and in order to improve tracking performance, the linear reduction of weighting is necessary. To test the efficiency of this method, the results of the simulation are implemented, they also show the performance of the MPPT method which is based on modified PSO by comparing it with that of the known PSO methods.
