Abstract
The increasing demand of non-linear loads and the revolution towards renewable energy sources connected at the utility scale, would potentially increase harmonic distortion in power distribution networks. Therefore, mitigation measures should be considered to deal with high levels of harmonics. Traditionally, a combination of passive filters has been used as an effective solution. However, the efficacy of such solution has not been investigated thoroughly in networks with high share of renewable energy sources, such as PVs. This paper analyzes harmonic distortions caused by distributed generators (PV) and non-linear loads connected to the 480 V distribution feeder. It aims to model and implement a collection of single-tuned passive filters to mitigate the harmonic levels and improve the power factor. The findings have been verified using a distribution feeder on MATLAB Simulink.
