A novel control strategy which enables proportional linear and nonlinear loads sharing among paralleled inverters and voltage harmonic suppression is proposed in this paper. The proposed method is based on the autonomous currents sharing controller (ACSC) instead of conventional power droop control to provide fast transient response, decoupling control and large stability margin. The current components...
Harmonic power sharing is important in islanded microgrid due to the presence of excessive nonlinear loads in distribution network. The lack of effective harmonic power sharing techniques may lead to overloading of certain distributed generation (DG) units. The concept of variable negative virtual harmonic impedance to share non-linear load in an islanded microgrid has been proposed recently. This...
In order to obtain a coordinated approach to integrate the increasing presence of distributed generation (DG) units in the electric power system, the microgrid concept has been introduced. Since most DG units use a converter as an interface with the grid, new control strategies for these converters are being developed. For the islanded mode of the microgrid, with the voltage-based droop control strategy,...
