Energy storage power station operation condition classification method and system, storage medium and server

Abstract

The invention discloses an energy storage power station operation condition classification method and system, a storage medium and a server. The method comprises the steps of collecting grid-connected operation condition data of an energy storage power station; preprocessing the grid-connected operation condition data of the energy storage power station to obtain a to-be-classified data set; judging whether a working condition classification model based on the random forest algorithm exists, if yes, inputting the to-be-classified data set into the working condition classification model based on the random forest algorithm for classification, and if not, training the working condition classification model based on the random forest algorithm; when the working condition classification model based on the random forest algorithm is trained, whether the working condition characteristic parameter system needs to be optimized or not is judged, if not, the working condition classification model based on the random forest algorithm is directly obtained, and if yes, the working condition characteristic parameter system is optimized based on the VIM of the working condition characteristic parameter importance measurement; and obtaining a working condition classification model based on a random forest algorithm. The working condition classification model based on the random forest algorithm has high tolerance to abnormal values and noise of working condition operation data.

Problems solved by technology

[0006] The above studies have made some progress in the classification and identification of energy storage conditions. However, the operating conditions are complex and changeable. In traditional research, the operating conditions are often purely subjectively calibrated, and the accuracy of sample labels and identification results is difficult to guarantee.
