Aside from environmental concerns and the exhaustibility of fossil energy sources, becoming more economical and lowering the cost of installing solar systems is driving the development of photovoltaic systems for energy delivery in many nations across the world. The formation of harmonics in the network and the effect of PV units on it are examined in this article. In this context, an active filter in the PV unit is employed to eliminate network harmonics. According to the non-linear behavior of PV units, the electronic power converter is managed in this technique to limit network harmonics induced by the non-linear demand. The proposed technique runs on the enhanced IEEE 33-bus system. The simulation results confirm that using the strategy provided in this article improves the power quality of this system.
