Control strategy of DC micro grids based on power flow

摘要

The control strategies of micro grid is an important topic for micro grid. With the development of DC micro grid, the control strategies of DC micro grid is drawing more and more attention. Nowadays, the most widely used control strategy of DC micro grid is droop control. All the distributed generators and energy storage systems share loads through different droop coefficients in droop control. This paper proposes a control strategy of DC micro grids based on power flow and realizes the control strategy based on PSCAD. The comparison between the control strategy and droop control is made to show the improvements.
