Total harmonic distortion mitigation and voltage control using distribution static synchronous compensator and hybrid active power filter

The incorporation of renewable energy sources (RESs) into power systems is now widely recognized as a crucial element of modern civilization. A significant obstacle in this situation is the reduction of voltage distortion and total harmonic distortion (THD), which can disrupt the smooth transfer of power and weaken the performance of electrical systems. When a power generation system integrates RESs, it results in the generation of both THD and voltage instability. Various types of active power filters (APFs), passive filters (PFs), compensators such as the synchronous condenser, static var compensator (SVC), static synchronous compensator (STATCOM), distribution static synchronous compensator (D-STATCOM), and hybrid active power filter (HAPF) have been developed in order to solve these problems. Along with those methods, various other techniques have been deployed to regulate voltage and minimize THD. However, this study involves a comparison of data between D-STATCOM and HAPF, with an emphasis on measurements of voltage waves, the 3rd and 5th harmonics, and THD. Three distinct capacitor banks, with capacities of 40-kilovolt ampere reactive (KVAR), 60 KVAR, and 80 KVAR, have been selected as references. All the relevant data for each of these referenced capacitor banks has been collected using MATLAB/Simulink software. HAPF outperforms D-STATCOM in every aspect of data analysis in this study. Although a simulation was conducted to determine if there would be any variations for different loads, no alterations were observed. This study aims to facilitate the selection of an appropriate device for industrialization, as failure to do so can have detrimental effects on the system.
