Abstract

Its necessary to study corresponding voltage control strategies for different wind conditions because the active power fluctuation caused by wind speed fluctuation is the fundamental reason of voltage problem. Considering tremendous changes of wind farm clusters running status under extreme wind conditions and limited closed-loop control capability of local reactive power continuously adjustable equipment, a corresponding voltage control strategy was proposed, which could provide preventive voltage control and corrective voltage control for conditions before/after extreme wind speed based on ultra-short-term wind power prediction. Its optimization algorithm could decouple the MINLP （mixed-integer nonlinear programming） problem through reactive power-voltage sensitivity method with considering active power change and turned it into an iteration containing a MILP （mixed-integer linear programming） problem and some nonlinear algebraic equations. By comparing the examples, the limitation of the traditional closed-loop control method and the superiority in voltage control and wind farms internal feeder voltage balance through the proposed control strategy can be verified, which can provide an effective method for solving the high voltage off-grid accident under extreme wind conditions.
