Abstract
This investigation is done for augmentation of steady-state voltage stability in microgrid with doubly fed induction wind generator for the growing need of DG systems in distribution and transmission network. A poor stability in voltage reduces the efficiency of the distributed generation system (DGs). Double Fed Induction Generator (DFIG) is a type of induction generator interconnected into microgrid and it acting an essential role during the performance of microgrid in distributed generation systems of distribution network. The performance characteristics of microgrid with DFIG is analyzed and improved by control strategy. The PI (proportional and integral) control strategy of microgrid with DFIG rooted in double-fed induction generator (DFIG) in pitch angle control in the energy storage system (ESS). The performance analysis microgrid with DFIG is implemented by means of simulink platform in MATLAB software. The outcome was evaluated in this article in favor of steady-state voltage stability enhancement in microgrid with DFIG. This work is done for the achievement of a stable operation microgrid in DG system against disturbances in wind. The proposed work is intended to produce 1.58 MW of reactive power without controller and 0.48 MW, 0.36 MW, and 0.32 MW of power with P, PI, and PID (Proportional–Integral–Derivative) controller with PAC.
