Power grid primary frequency modulation data prediction method and device based on LSTM

The invention provides a power grid primary frequency modulation data prediction method and device based on LSTM. The power grid dispatching operation safety data prediction method comprises the steps: original data is acquired, wherein the original data is in a first format; format conversion is carried out on the original data to obtain second data, wherein the second data is in a second format,and the second format is different from the first format; data cleaning is carried out on the second data, and useless data is deleted to obtain third data, wherein the third data comprise time, active power, direct-current delivery, hydropower active power and thermal power active power; and the power grid frequency is predicted according to the third data by using a first prediction model. According to the invention, the problem of lack of system risk perception capability and early warning capability in the prior art is overcome, and the power grid dispatching safety is further improved. 本发明提供一种基于LSTM的电网一次调频数据预测方法
