Unbalanced Voltage Compensation Using Grid-Connected Photovoltaic System
AUT Journal of Electrical Engineering, 2022 Appropriate power quality is indispensable for electrical distribution networks, especially in microgrids including renewable energy sources. One of the critical issues affecting power quality is the unbalanced voltage. Voltage imbalance in microgrids spreads due to proximity of loads and power sources, causing instability, and eventually interruption.
