Feature Decoupling Peak-load Forecasting Model Considering Meteorological Cumulative Effect
The summer peak-load is the focus of the power industry
and temperature cumulative effect has an important impact on the summer peak-load forecasting. Therefore
a feature decoupling peak-load forecasting model considering meteorological cumulative effect is proposed. The deep neural network model with three input branches is established to realize the decoupling of input features from the structure
which is called feature decoupling model. The three branches take the time feature
load feature and meteorological feature as the input
respectively. The branches for the load and meteorology apply the hidden layer of the long short-term memory (LSTM) network. The load and meteorological sequences are processed based on the time sequence processing ability of LSTM network to the reflect cumulative effect
and then apply it to the peak-load forecasting. Finally
through case analysis and comparison with conventional methods such as temperature correction method
it is verified that the feature decoupling model is more suitable for peak-load forecasting considering cumulative effect.
