ENCHANCEMENT OF POWER QUALITY USING ACTIVE POWER CONTROL

Abstract

The concepts of line frequency transformer and voltage regulation are closely connected to the operation of a bidirectional microgrid. One of the primary challenges associated with hybrid microgrids is the issue of spatial occupation, which poses a significant concern. Additionally, another noteworthy challenge is the problem of increased resource consumption. The present study aims to address the challenges identified in the research by proposing a novel approach known as the Bidirectional Recursive Decision Tree (BRDT). The design of the Bidirectional Resonant Dual Transformer (BRDT) follows a straightforward loop configuration, which exhibits a duty ratio of 50%. This duty ratio is considered superior to the phase shift method. The BRDT (Bridge Resonant Dual Topology) incorporates many topologies, including CLLC (Capacitor-Inductor-Inductor-Capacitor), CLL (Capacitor-Inductor-Inductor) and LLC (High Frequency Transformer) configurations. When a high frequency transformer is utilized, there are certain consequences that arise due to leakage inductance and magnetizing inductance. The experimental verification of the BRDT prototype and hybrid AC/DC microgrid is conducted using MATLAB simulation. It is essential to examine the outcomes of both transient and steady state phenomena.
