An Adaptive Voltage Control Using Local Voltage Profile Mode and Similarity Ranking

Frontiers in Energy Research, 2022
Emergency voltage control provides a real-time online response to maintain the long-term voltage stability of a power system. Searching for an optimal emergency control solution is a hard combinatorial optimization problem because of the highly dynamic and nonlinear characteristics of power systems with discrete control variables.
