Fast line drop compensation in low voltage regulators

New power electronic regulators with fast response capability are becoming available, and these can also perform fast line drop compensation. Such regulators are helpful in solving the challenges created by distributed generation and increasingly variable loads. A faster regulator response opens up new control options to address voltage fluctuations due to changes in load current, because a system operator can consider the tradeoff between steady voltage at the regulator output terminals and steady voltage at the remote reference point. Different rate control options are explored in this paper.
