Investigation of Power Quality Analysis of Three-Phase Inverter Topologies for Renewable Energy Systems
Today's, renewable energy systems are extending day by day and becoming more and more popular. Most of renewable resources are wind turbines, fuel cells and solar cells. Due to increasing to integration these renewable energy systems (RES), effect of RESs on quality of electric power are increasing day by day. Inverter is one of main component of these renewable energy systems. Inverters are becoming popular with spread of the use of RES. Inverter is main component of RESs which converting direct current to alternating current; for these reasons, Inverter main part of RESs which related to power quality and inverter design are important for quality of electric power. This project aims designing different three-phase inverter topologies for using RESs with different circuit topology at different load condition and give analyze of their characteristic in terms of current waveform and comparing DC injection, total harmonic distortion and individual harmonics with help of PSIM and MATLAB Simulink.
