Short-Term Load Forecasting Model Based on Quantum Elman Neural Networks

الملخص EN

Short-term load forecasting model based on quantum Elman neural networks was constructed in this paper.

The quantum computation and Elman feedback mechanism were integrated into quantum Elman neural networks.

Quantum computation can effectively improve the approximation capability and the information processing ability of the neural networks.

Quantum Elman neural networks have not only the feedforward connection but also the feedback connection.

The feedback connection between the hidden nodes and the context nodes belongs to the state feedback in the internal system, which has formed specific dynamic memory performance.

Phase space reconstruction theory is the theoretical basis of constructing the forecasting model.

The training samples are formed by means of K -nearest neighbor approach.

Through the example simulation, the testing results show that the model based on quantum Elman neural networks is better than the model based on the quantum feedforward neural network, the model based on the conventional Elman neural network, and the model based on the conventional feedforward neural network.

So the proposed model can effectively improve the prediction accuracy.

The research in the paper makes a theoretical foundation for the practical engineering application of the short-term load forecasting model based on quantum Elman neural networks.
