Application of Line Reactors and Harmonic Filters in Electric Power Systems are Integrated Renewable Energy in Mesh Topology

Now electric power providers are starting to reduce the use of fossil fuels and add renewable energy to the power system. Generally, the integration of renewable energy into the electric power system uses a mesh topology. The goal is to reduce air pollution and save fossil fuels, so that fossil fuels can be used for other needs. Most renewable energy utilizes the electronic power device to optimize the renewable energy output power. Power electronic devices that include nonlinear loads can increase harmonic distortion if there are too many of them in the electric power system. The purpose of this paper is to reduce harmonic distortion in the electric power system by using a line reactor and harmonic filter. Several simulation conditions were created to show evidence of a decrease in harmonic distortion after using a line reactor and harmonic filter. The first condition, harmonics on the object of the electric power system without harmonic filters and line reactors. The second condition, the reduction of harmonic distortion on the same object using harmonic filters. The third condition, the reduction of harmonic distortion using a combination of harmonic filters with a line reactor. The first condition result in THD-V value of 10.67% and THD-I value of 4.01%. The second condition gives value of THD-V6.91% and THD-I 3.16%. The third condition is able to give result of THD-V 3.17% and THD-I value of 1.64%. The third condition gives the most favorable results compared to the previous conditions.
