碩士 === 國立彰化師範大學 === 工業教育與技術學系 === 103 === The main purpose of this thesis is to establish a multi-object function for the optimal phase arrangement of distributed energy resources and loads in an active distribution network. It can be reduced the three-phase voltage unbalance ratio, system power loss and voltage variations, and furthermore the system operation efficiency will be improved. Therefore, this thesis using COM Engine dynamic link technique to combined two software, Matlab and OpenDSS, to solve the optimal phase arrangement problem. The optimal searching algorithm was coded in Matlab, and the system modeling was established in OpenDSS according to system topology. Finally, the IEEE 13-Bus and IEEE 37-Bus testing system were used as the sample systems to verify the accuracy of the proposed approach. The simulation results demonstrated that the proposed approach is systematic and efficient for solving the optimal phase arrangement in active distribution networks. The outcomes are also helpful for the distributed energy resources interconnected into distribution networks for improving the system performance.
