Power Flow control is very important procedure when renewable
sources are connected to electric grid. Furthermore, Most common
topologies of grid tied distributed generation have inductor attached
to power converters.
In this article, the role of
inductors linking between power
converters and electric grid is analyzed. Values of these inductors
can affect largely the value of Power flow (Active and Reactive
power) in both sides, while phase angle between voltage of
terminals determines the direction of power flow.
This paper proposes MATLAB/SIMULINK models to study this
impact, for different operation conditions (four quadrants I-V
curves). Two methods of coils calculation are applied, in order to
design the best value calculated in the proposed
MATLAB/SIMULINK models.
