Abstract: The work is intended to extend the application of smart transformer on a radial distribution system. In this paper an updated algorithm on the backward/forward power flow is introduced. The so-called direct approach power flow is employed and analyzed. In addition, the paper focused on integrating a smart transformer to the network and solving the updating network also using the direct approach load flow. Solution of the smart transformer using the direct approach power flow method is quite straightforward. This model is applied on a radial distribution system which is the IEEE-33 bus system as a case study. Also, the paper optimizes the best allocation of the smart transformer to reduce the power losses of the grid.

Keywords: Smart transformer, smart grid, direct approach, power flow, power loss reduction
