Short-term Power Forecasting of Multiple Wind Farms Considering Dynamic Spatial-temporal Correlations
摘要
Abstract
Aimedat the complex and dynamic spatial-temporal correlations between the output of multiple wind farms in the same region,a short-term power forecasting model of multiple wind farms based on the attention based spatial-tem-poral synchronous graph convolutional networks is proposed.First,an attention mechanism is introduced to quantify the impact of weather features on wind power,the local spatial-temporal graphs of wind power are constructed in three adja-cent time steps,and the local spatial-temporal features are extracted through convolutional calculation.Then,the input window's overall spatial-temporal features are aggregated using the spatial-temporal synchronous graph convolutional layer.Finally,the power prediction results of multiple wind farms in the future are output through nonlinear mapping.The results of an actual example show that the proposed modelcan improve the day-ahead power forecasting accuracy of-multiple wind farms by 2.10%—13.94%through learning the dynamic spatial-temporal evolution law of wind power un-der different weather conditions.关键词
