Fuzzy Based Control Strategy With Voltage Sustain Capability For Distributed Generation Inverters Under Voltage Sags
Now-a-days voltage sags are one of the main troubles in transmission and distribution grids with high incursion of
distributed generation. A voltage sustain control strategy for grid-connected power sources under voltage sags is anticipated
in this project. The control is based on the infusion of reactive current along with a flexible ratio between positive and
negative series. The controller finds, also, the amount of reactive power required to renovate the declined voltage magnitudes
to new allusion values confined within the continuous operation limits required in grid codes. These allusion values are
preferred so as to assure low current injection when satisfying the voltage sustain purpose. The proposed model can be
designed in MATLAB/SIMULINK and the results conveyed so as to endorse the efficacy of the proposed control.
