Advanced voltage regulation method at the power distribution systems interconnected with dispersed storage and generation systems

Summary form only given as follows. DSGs (dispersed storage and generation systems) in power distribution systems impact on the conventional voltage regulation method. Therefore, there is the possibility that the customers´ voltage violates the permissible limits. In this paper, we propose the MLDC (multiple line drop compensation) voltage regulation method which considers the unbalanced load diversity among feeders, the operations of DSGs, and the hysteretic tap changing mechanism of ULTC (under load tap changer). The result from a case study shows that the proposed MLDC method can be practically applied to the voltage regulation method at the power distribution system interconnected with DSGs and severely unbalanced load diversity among feeders
