POWER QUALITY ANALYIS FOR POWER LED DRIVES

Abstract

DC micro grids have grown increasingly popular in the energy grid in recent years, as distributed generation has increased. Distributed generation refers to small or large-scale renewable energy that is linked to the main power system. Renewable energy sources like solar and wind power help the local grid, but their output is inherently intermittent and unpredictable, interfering with regular grid operation. Some of these issues can be mitigated by using energy storage in conjunction with renewable energy. Renewable energy is often linked to the grid using power electronic converters. 
 The goal of this research is to simulate and evaluate transmitted emissions in the time and frequency planes using IEEE 1459 to investigate the impacts of DC / DC converters on DC lines, particularly for renewable energy generation. While there are standards and norms for frequencies up to 2 kHz and beginning at 150 kHz, the frequency range 2-150 kHz only has suggested techniques and propagation restrictions. As a result, the emission conveyed in the frequency range of 2-150 kHz is a subject that must be comprehended. The structure of the generation model, as well as the idea of power quality in electricity generating models, will be investigated using data collected through experimental and computer simulations on a medium-scale hybrid network connected to the grid. The technological advances acquired will subsequently be utilized to evaluate the power quality of various DC and AC single/three phase power systems (such as computer servers, airplanes, and so on).
