Abstract
This paper deals with the stability issues of grid integrated distributed generations through voltage source inverter (VSI). Distributed generation is now increased day by day due to demand of power so power production from nonconventional sources is connected to the grid via VSI with traditional PI controller for controlling of grid currents. Due to grid impedance variations, the PI controller’s bandwidth and their low frequency gain has to be reduced to maintain the system stability, thus debasing the tracking routines and capability of rejecting disturbance of system tends to unstable. In this proposed methodology, the VSI is controlled by the way of novel controller long with stability is analyzed. This proposed technique determines the grid stability which relies upon the impedance of VSI and the impedance of grid network. It expresses that the electrical grid network stays stable if the proportion of inverter impedance to grid network impedance fulfills the Nyquist stability criterion. The simulation of the novel controller scheme and the traditional PI regulator with VSI are given and analyzed, which approves the exhibition of the methodology.
