Abstract :
The frequency and voltage droop control is one important method which can deal with power sharing problem and realize “plug and play” function in microgrid. But it is subject to the power coupling and steady-state reactive power sharing error when employed in low voltage microgrids. Furthermore, complex microgrid configurations often make the power sharing more challenging. In this paper, an accurate power sharing strategy has been proposed based on droop control method and communication platform. DG units upload power output information to microgrid control center (MGCC), and receive averaged reactive power instruction from MGCC. The power flows and voltage of microgird will be regulated on line. Finally, the proposed methods will be tested in MATLAB simulation and the results validate the feasibility of them.
