Distribution system voltage stability analysis with wind farms integration

Stability Boundaries for Offshore Wind Park Distributed Voltage Control

“…At the boundary of (k pv , k iv ), the system becomes marginally stable, validating the set. The current control loop contributes with poles p 3,6 , which stay in the LHP for all k pv and k iv . Increasing k pc in violation with (24) produces a complex pole pair that increase R( p 4,5 ), enlarging (k pv , k iv ).…”

“…If the estimation of the system parameters is poor, local voltage profile regulation can lead to reactive power oscillations [5]. Furthermore, local voltage control may influence voltage flicker, caused by unwanted interaction between individual control loops [6], [7]. An assessment of the static voltage stability of a power system considering all power controls was presented in [8], using singular values, but dynamics of interacting converter systems in a network affect the parameter range of stabilizing controls and instability could occur [9].…”

Overcoming Challenges of Renewable Energy on Future Smart Grid

“…which affects the power system voltage stability. [14][15][16][17], addressed the challenges of wind energy fluctuation and intermittency to system stability and control for the future smart grid.…”

Challenges of large wind generation intermittence and fluctuation for future smart grids

“…So the influence of wind generation on power system voltage stability is being more and more emphasized by scientists and engineers, particularly in the era of smart grid. The issues addressed in [27][28][29][30][31][32][33][34][35][36][37][38][39] would be the potential challenges to system stability and control for the future smart grid. In [27], an accurate voltage stability index (VSI) is needed to quantify the voltage stability margin in a distribution system with wind farms connected.…”
