Optimization of the power flow of photovoltaic generators in electrical networks by MPPT algorithm and parallel active filters

This article presents a method for the reduction of harmonics generated by photovoltaic generators in electrical networks. Very often, photovoltaic generators produce harmonics due to the nature of the direct current they generate. In order to eliminate these harmonics, parallel active filters are u...
