Renewable energy power generation power prediction system and method for advanced marking

The invention provides a renewable energy power generation power prediction system and method for marking in advance, and the method comprises the steps: building a renewable energy power generation power prediction framework through a marking result obtained through an early generation power mode marking algorithm; the system comprises a data collection module, a data preprocessing module, an advance mode marking algorithm module, a feature engineering module and a hybrid multi-step prediction module, and the hybrid multi-step prediction is completed by combining the advance mode marking algorithm with the feature engineering through a proper feature and model training method. A mode marking model is generated, mode marking features are performed in advance, and a new input feature variable-mode tag is provided for a future prediction period, so that more useful information can be mined from historical data, a mixed multi-step prediction method is adopted, the prediction accuracy and stability are improved,
