Control of Line Loss Minimization on Power Distribution System for Smart Grids

为了减少配电系统的线路损耗，用户安装了功率因数自动调节器。然而，安装自动功率因数调节器的比例不到50%，没有实现线路损耗的降低。本文提出了一种基于智能电网的配电系统控制方法。在本文提出的控制中，现有的自动功率因数调节器利用配电系统中的节点电压和线路电流进行控制，可将无功电流引起的线路损耗降低到10%。利用实验室样机进行了实验，验证了该控制方法的有效性。

For reducing the line loss in power distribution system, the consumers install the automatic power factor regulator. However, the ratio for installing the automatic power factor regulator is less than 50 %, and the line loss reduction is not realized. In this research, novel control of the distribution system based on the smart grid is proposed. In the proposed control, the existing automatic power factor regulators are controlled by using the node voltages and line currents in the distribution system, and the line loss caused by the reactive current can be reduced to 10 %. The effectiveness of proposed control is verified by the experiments using the laboratory prototype.
