Diseño de un filtro activo para la mitigación de perturbaciones armónicas inyectadas por electrolineras en una red de distribución usando el método de referencia síncrono

Abstract

The present study analyzes the level of harmonic distortion in an IEEE distribution network of 30 nodes, caused by the operation of electric vehicle charging stations. The increasing integration of these stations into distribution networks has raised concerns regarding the impact of harmonics on energy quality and system performance. To address this problem, detailed simulations and measurements of the harmonics present in the network have been carried out, identifying the most affected nodes and evaluating the general impact on the stability and efficiency of the system. In order to mitigate these adverse effects, an active filter has been designed and implemented in accordance with IEEE 519- 2014 regulations. This active filter has been optimized to minimize total harmonic distortion (THD) in the distribution network, significantly improving the quality of the energy supplied. The results of the implementation demonstrate an effective reduction of harmonics, complying with the limits established by the regulations and showing the feasibility of the use of active filters in distribution networks with high penetration of charging stations.
