摘要：

A smart transformer (ST) based meshed hybrid distribution network is realized by extending ST low voltage dc (LVDC) link to form a LVDC line which connects dc buses of existing distributed generation (DG) converters. This paper proposes a method for power loss minimization in such ST based meshed hybrid distribution network. A CIGRE LV residential distribution network with DG sources is connected at ST LVAC and LVDC terminals. An online optimal problem is formulated for determining the active and reactive power references of DG converters for minimized power losses in line. The total power loss minimization at each time is chosen as the objective function and solved using genetic algorithm. The total loss in the system is the sum of both LVAC and LVDC line losses. This total loss is calculated using the backward forward sweep power flow method. The proposed method is tested in MATLAB.
