Unbalanced Load Modeling and Control in Microgrid with Isolation Transformer

Renewables and energy storage rely heavily on power electronics. The control of power electronics in a microgrid with renewables and energy storages become more challenging under unbalanced load operation condition. The unbalance in current magnitude and phase will cause ripples in normal dq0 conversion, further causing voltage unbalance in the power converter current control loop. In this paper, ...
