Reliable Smart Transformer Integration in Micro Grids

Abstract

The proliferation and ever-growing of the renewable energy sources and the appearance of recently upgradable loads as electric vehicles (EV) and its charging stations may cause some of the operational and technical challenges for the distribution systems and may occur extremist variation in the traditional interpretation of the distribution network. Although the numerous pros due to the improvement of the distributed generations spatially in the renewable energy field, one of the main challenges that consider as constrain to the distribution network is evolving the possibility to owe a bidirectional power flow which occurred by varying load profile and generation profile. Therefore, the uprising utilization of the distributed generation may affect on the performance of the power system and causes many problems like overvoltage and Under voltage, overloads, power losses. Therefore, the utilization of the smart grid and microgrid is become widely used in modern networks. The smart grid has many features as it enhances the network efficiency, decreasing the power losses in addition to less cost than the traditional one and the smart grid able to be monitored and controlled. One of the important parts of the smart-grid component is the smart transformer.
