Control de armónicos de corriente mediante la implementación de un filtro activo unificado usando control proporcional integral en el sistema de distribución con generación fotovoltaica.

Abstract

In the present research work, a harmonic current compensation method called Unified Active Power Filter is proposed, which has as its source an array of solar panels together with a boost converter that is abbreviated UAPF-PV, which is designed to be work in low voltage distribution networks, to reduce the harmonic component of current. This method uses two types of active filters, one of them is the series filter which uses transformers, this filter has the compensating the harmonics that are present in the voltage waveform. Other type is the parallel power filter, which takes as reference the voltages and currents measured in the load, thus compensating for current harmonics. The analysis was in an IEEE 13-bar system in which a non-linear load is integrated in the 7th bar of the mentioned system. The components of voltage, current and the total harmonic component present in bus 7 of the system and in the load were analyzed. The results obtained were the decrease in current and voltage harmonics in bus 7 of the system, where it went from having 13.5% to 6% in the THDi these values are within the IEEE 1159 standards and resolution No. ARCERNNR -017/2020.
