To use distribution networks effectively and to smooth introduction of the distributed generations, we proposed the loop or mesh structure for the distribution systems using loop power flow controller (LPC) at the opened switch which can connect the adjoining feeder. LPC is able to optimal control for distribution systems in the points of reducing voltage rise, voltage fluctuation and loss minimum power flow control, and so on, with acquisition of state of distribution systems. Adapting to the area that cannot use communication system, points of view at the power quality for the transition phenomena, we also required the distributed control using local voltage information for the LPC control. The purposes of this paper show a total power flow control structure of LPC and propose a determination method of control coefficients using object function that describe optimal condition of the network. The distributed control using control coefficients by proposed determination method shows suitable operation for disturbances of DG (distributed generator).
