Strategy for Controlling Total Current Harmonics Distortion by means Photovoltaic Generation with an Unified Active Power Filter (UAPF)

In this paper, an Unified Active Power Filter (UAPF) is proposed for controlling the current Total Harmonic Distortion (THD) in low voltage distribution networks. The UAPF implements photovoltaic (PV) generation as its source, together with a boost converter. The IEEE 13-bar system is the test-bench, and a non-linear load is in the 7th bus-bar. Thus, discusing the results of the voltage, current and THD in the system. The results were decreasing current (THDi) and voltage (THDv) harmonics, the THDi and THDv reduce to 6 percentage, and 3 percentage, respectively. The results are within the allowed limits in IEEE 1159 standards and ARCERNNR -017/2020 resolution.
