Description
Summary:Traditional voltage - frequency control scheme for microgrid in islanding operation and active power - reactive power control scheme in grid-connected operation all have their disadvantages. This paper proposes a fuzzy and decoupled d-q based active power and voltage control strategy for microgrid operating in islanding mode, which can avoid the disadvantages. The mathematical model are formulated in d-q axis frame, applying decoupled d-q current control method to support active power and voltage control. Moreover, fuzzy rules are used to set the parameters of proportional-integral control. The simulation results demonstrate that the proposed approach performs well and will have great significance for extending toward multiple inverters fed microgrid.
