Bus Load Forecasting Method of Power System Based on VMD and Bi-LSTM

Abstract: The effective prediction of bus load can provide an important basis for power system dispatching and planning and energy consumption to promote environmental sustainable development. A bus load forecasting method based on variational modal decomposition (VMD) and bidirectional long short-term memory (Bi-LSTM) network was proposed in this article. Firstly, the bus load series was decomposed into a group of relatively stable subsequence components by VMD to reduce the interaction between different trend informat… Show more

“…Therefore, the same parameters as for LSTM in Table 1 are also used for Bi‐LSTM. Bi‐LSTM network is derived as the cyclic bidirectional architecture of the traditional LSTM network [55]. This architecture splits traditional LSTM in two directions, but there is a link to the same output layer for both LSTMs.…”

“…Secondly, in the comparison of the latest prediction models, this paper uses the VMD-Bi-LSTM prediction model proposed by Tang [33], the VMD-CISSA-LSSVM prediction model proposed by Guijuan Wang [34] and the VMD-GWO-SVR prediction model proposed by Mengran Zhou [35] to compare with the VMD-SG-LSTM. Each parameter is set according to the value in the article to predict the power load in the next hour.…”

“…Nevertheless, the VMD algorithm also has limitations, including the need for manual parameter configuration and potential instability. In [24], a method based on VMD‐BiLSTM was introduced, in which the Bayesian optimization algorithm is utilized to optimize the hyperparameters of the model. Like EMD, this approach decomposes the original data into multiple components for individual predictions and subsequently combines them.…”
