Abstract
Smart grid uses digital technology to increase reliability, security, and efficiency of the electrical systems. The use of renewable energy is the most important factor in development of smart grid. The voltage source inverter (VSI) and current source inverter (CSI) are used for interfacing renewable sources to grid. The contents of total harmonic distortion (THD) of VSI and CSI inverter is high, hence, it requires filter circuits for mitigation. Z-source inverter (ZSI) overcomes the above-mentioned limitations of inverters and it delivers a power conversion theory. Total harmonic distortion created by EZ source inverter is less as compared to Z-Source inverter. The EZ source inverters are the modest alternatives that can be used for cases where better quality of power is required. This paper reviews the use of Z- source inverter and EZ source inverter in the integration of renewable energy source in the smart grid.
