Embodiment Construction

[0074] The specific embodiments of the present invention will be described below with reference to the accompanying drawings, so that those skilled in the art can better understand the present invention.

[0075] figure 1 Unroll the topology map for Simple Recurrent Neural Networks - Real Time.

[0076] Generally, neural network models can be divided into feedforward neural network (FFNN) and recurrent neural network (RNN). FFNNs are widely used to process data in the spatial domain while ignoring data occurrences about time (i.e., temporal information). On the other hand, RNN architectures can be viewed as loop-back architectures with interconnected neurons that can model sequential and temporal dependencies between data on a larger scale [43] .

[0077] The standard for RNN architecture is in figure 1 given in. Each node in the network starts from the current state (x t ) receives input and returns from the previous state (h (t-1) ) receives the hidden state value of ...

Abstract

The invention belongs to the field of control of power demand side response relates to a building energy consumption prediction method based on a long-term and short-term memory network hybrid model,and provides an energy consumption prediction model for a building, and the model adopts a long-term and short-term memory network LSTM and an improved sine and cosine optimization algorithm. Accurateand reliable building energy consumption prediction can be performed, meanwhile, a novel Haar wavelet-based mutation operator is introduced, so that the divergence of the sine and cosine optimizationalgorithm to the global optimal solution is improved. The proposed improved sine and cosine optimization algorithm ISCOA can optimize hyper-parameters (learning rate, weight attenuation, momentum andhidden unit number) of the LSTM. The ISCOALSTM proposed by the method can calculate a stable and accurate prediction result, and further serves as an effective tool for solving a problem of energy consumption prediction.

Description

technical field [0001] The invention relates to the control field of power demand side response, in particular to a building energy consumption prediction method based on a long-short-term memory network hybrid model. Background technique [0002] With the rapid growth of the global population, the development of industrialization, the development of economy, and the development of life and society, these developments have had a significant impact on global energy consumption and the environment. 92% of people live in buildings, increasing the operation of energy-intensive buildings to meet people's living needs and comforts, which account for 80-90% of total energy consumption over the building's life cycle. With buildings accounting for about 39% of global energy consumption and greenhouse gas emissions accounting for about 38% of global emissions, buildings have become the largest consumer of energy. According to the International Energy Outlook 2017, “Electricity is the...
