Abstract: This paper presents an accurate tool for tracking the voltage unbalance in the microgrid. This accurate tracking depends on a new formulation of the adaptive linear neuron (ADALINE). This formulation has accurate estimation/extraction of positive-, negative-, and zero-sequence voltages. The paper introduces a control scheme that stabilizes the voltages at the loads side by adjusting the positive voltage around 1 pu and mitigating the negative-sequence voltage. This voltage stabilization is done through the developed control scheme, which has a cascaded-loop structure for voltage and current control. The control scheme along with the suggested estimation tool gives accurate results for stabilizing the voltage at the loads side for different loading conditions.
