Power interchange by the DC bus in micro grids

Abstract

In this paper, DC power interchange is confirmed to reduce the battery damage by according to the fluctuations in the battery voltage in each micro grid. We investigated various conditions that constructed the DC power interchange system in two micro grids using the DC power flow controller. The experiment examined DC power interchange between two micro grids. As a result, it is able to expect that the installation cost of generator systems and storage systems are reduced.
