Embodiment

[0157] The main purpose of this embodiment is to verify the effectiveness and rapidity of convergence of the algorithm of the present invention. In the experiment, a total of 17,376 groups of wind and solar power generation and consumption data in Gansu from January to June 2018 were used as the training set for training. The learning rate was uniformly set to 1.5, the adaptive update coefficient adjustment range was 0 to 2, and the number of training iterations was the largest. The value is 1000 and the training accuracy is 10 -3 . The training results of the algorithm of the present invention and the conventional dynamic recursive neural network are as follows: Figure 5 shown. It can be seen from the figure that the two algorithms can finally meet the convergence accuracy requirements, and the algorithm of the present invention has a faster convergence speed in the early stage of training, and the number of iterations required to achieve the training accuracy is less.

Abstract

The invention belongs to the technical field of new energy power generation consumption and discloses a new energy consumption method based on depth learning. The method is characterized in that a back propagation algorithm of the multi-layered perceptual neural network is utilized for realization, and training is performed through utilizing the improved dynamic recurrent neural network method; the optimization process includes the offline training process of a deep learning model, and the other part is the online optimization process of a deep learning optimization controller. The method is advantaged in that the depth learning-based consumption optimization algorithm can determine optimization controller parameters online according to the content and the quantity of different optimization targets and the content and the quantity of different constraints without the need of artificial adjustment, the method is universally adaptable for application scenes, the dynamic recurrent neuralnetwork model training method based on an adaptive update coefficient can overcome disadvantages that the conventional dynamic recurrent neural network has the slow convergence speed and is easy to fall into a local minimum value, and the training time of an optimization controller model is shortened under the premise of ensuring accuracy.
