چکیده
In order to improve the accuracy of power load forecasting, this paper proposes a neural network-based short-term monitoring method. First, original energy signal is decomposed by CEEMDAN algorithm obtain several eigenmode function components and residual components; functions are fed into NARX network for computational purposes. The partial hypothesis superimposed in following part final forecast. According test results, MAPE CEEMDAN-NARX model 4.753%, 3.540%, 0.343% lower than SVM, RNN, models, respectively, 3.741% 2.682% CEEMDAN-SVM CEEMDAN-RNN, respectively. RMSE 0.765% 101.7 MW, which 0.468% 45.2 MW Compared CEEMDAN-SVM, CEEMDAN-RNN decreased 0.986% 0.692%, 111.5 65.7 compared CEEMDAN-SVM. Conclusion that forecasting based on combination can effectively connect, reduce negative impact noise accuracy.

Short term electric load prediction based on deep neural network and wavelet transform and input selection
Electricity demand forecasting is one of the most important factors in the planning, design, and operation of competitive electrical systems. However, most of the load forecasting methods are not accurate. Therefore, in order to increase the accuracy of the short-term electrical load forecast, this paper proposes a hybrid method for predicting electric load based on a deep neural network with a...
متن کاملA New Approach for Investigating the Complexity of Short Term EEG Signal Based on Neural Network
Background and purpose: The nonlinear quality of electroencephalography (EEG), like other irregular signals, can be quantified. Some of these values, such as Lyapunovchr('39')s representative, study the signal path divergence and some quantifiers need to reconstruct the signal path but some do not. However, all of these quantifiers require a long signal to quantify the signal complexity. Mate...
متن کاملA Neural Network Based Short Term Load Forecasting
The electric load is strongly related to meteorological conditions and forecast models depend on climatic studies. The most used variable is the air temperature, because there is a close relation between thermal state of well being and the corresponding load (air-conditioned apparatus for instance). Due to certain matters like the increase of cities and terrain geography, the air temperature ha...
