Deсentralized Voltage Emergency Control in Electric Power Systems with Application of Sensitivity Analysis

<jats:p>A current issue of maintaining the acceptable voltage levels and the load stability in complex electric power grids is considered. The concept of decentralized voltage emergency control with application of sensitivity analysis for selecting the control action locations is proposed. The obtained control action amounts demonstrate the eff ectiveness of the proposed method using simulations on a real network fragment. The proposed system concept allows for prevention of load instability and compensate the excessive control actions by automatically reconnecting the load.</jats:p>
