Optimal Control Strategy for Field-Level Active Voltage Regulation Considering Wind Power Operation Trajectory and Scene Division
摘要
Abstract
The traditional way of regulating wind farm based on the voltage command from the main station often leads to frequent fluctuations of reactive power sources within the sta-tion as well as insufficient reactive power margin,which af-fects the regulation capacity of the wind farm.Therefore,a new active voltage regulation optimization control strategy at field level is proposed considering wind power operation trajectory and scene division.First,based on the power prediction data of the wind farm and the active voltage sensitivity curve,the voltage fluctuation trajectory of the parallel node is drawn.The coordination of reactive power output of the wind turbine and the SVG,in combination with the voltage command received by the AVC substation,effectively reduces the regulation fre-quency of reactive power equipment.The detailed operation scenarios are further categorized based on the amplitude of the voltage drop,and the effective suppression of large ge-fluctu-ations of grid voltage is realized by adjusting the control mode of SVG.Finally,a simulation test platform incorporating AVC power controller is constructed to verify the effectiveness of the proposed method in reducing reactive power regulation fre-quency,enhancing the reactive power margin,and providing active voltage support compared to the traditional AVC control strategy of wind farms.This offers a new solution for realizing active voltage regulation in wind farms.关键词
