Abstract
This paper analyzes the impact of current sensing inaccuracies due to aging and ambient condition variations on robust operation of PV inverter systems. A novel index for analyzing the robustness of grid-tied AC-stacked PV inverter architectures has been used, which provides an opportunity for comprehensive robustness evaluation by considering four major operational characteristics of grid-tied PV inverters as efficiency, Total Harmonic Distortion (THD), Power Factor (PF) compliance, and Maximum Power Point Tracking (MPPT) effectiveness. In addition, a comparative analysis between a single inverter and an AC-stacked inverter configuration is provided to study the impact of AC-stacking on robust operation of grid-tied PV inverters. This paper also proposes a possible state estimation solution for improving the robustness of the system using Kalman filter approach.
