The invention discloses a wind power plant grid-connected point reactive power regulation method and device, equipment and a storage medium. Various data of a system are trained by using a multivariable linear regression model, and a required reactive power reference value is efficiently and accurately obtained according to a target voltage value. And then the voltage of a grid-connected point is adjusted by using the reactive power of the wind field, thereby being beneficial to ensuring the voltage stability and reducing fluctuation interference to a large power grid. The method can be used for solving the problems of low regulation speed, low active power prediction accuracy and the like of reactive power regulation of grid-connected point voltage at the current stage. 本发明公开了风电场并网点无功调节方法、装置、设备及存储介质，利用多变量线性回归模型对系统各项数据进行训练，高效准确地根据目标电压值得出所需要的无功功率参考值。然后利用风场无功功率调节并网点电压，有利于保证自身的电压稳定以及减少对大电网的波动干扰。该方法可用于解决当前阶段无功功率调节并网点电压存在的调节速度慢、有功功率预测准确度较低等问题。
