Flexible loop-closing phase-shifting voltage regulator type selection configuration optimization method and system

The invention provides a flexible loop-closing phase-shifting voltage regulator type selection configuration optimization method and system. The optimization method comprises the following steps: collecting power distribution network information and historical load data; a load prediction model based on a CNN-ARIMA-LSTM algorithm is established; establishing a plurality of voltage regulator and power transmission line calculation models; giving the capacity and model range of the voltage regulator to obtain a basic configuration scheme; respectively calculating each configuration scheme based on each calculation model, carrying out load prediction, further carrying out safety judgment, and outputting a configuration scheme meeting a preset value; and performing weighted score calculation on each model output value of the configuration scheme meeting the preset value, and selecting the configuration scheme with the highest weighted score as the optimal configuration scheme for output. According to the scheme,
