Analysis of Power Quality for Photovoltaic Systems Connected to the Grid

From the advancement of alternative power generation systems, in conjunction with its technical feasibility for direct connection to the conventional power grid, diversification of global energy has been growing with the introduction of distributed energy production which results in a new need adaptation to allow the connection with these systems, in addition to determination of power quality control parameters that fall within the limits of operation and supply are extremely important for ensuring compliance with the power quality levels, as well as the optimization of generation potential that is critical to predict the behavior and meet production expectations. This requirement makes the utilities and the responsible agencies take steps to enable the monitoring and effective correction of these systems, making them efficient and avoiding any risks or damage to the growing demand for energy supply. To contribute to the power quality control processes, this paper aims to proposed use of passive filters to reduce the harmonic distortion levels injected into the grid from computer modeling to simulate the conditions of a real photovoltaic (PV) system connected to the grid, and the use of energy analyzers designed to measure the quantities of interest and subsequent comparison of the data obtained in the field for improved reliability of the final result.
