LoadCNN: A Efficient Green Deep Learning Model for Day-ahead Individual Resident Load Forecasting
share
Accurate day-ahead individual resident load forecasting is very important to various applications of smart grid. As a powerful machine learning technology, deep learning has shown great advantages in load forecasting task. However, deep learning is a computationally-hungry method, requires a plenty of training time and results in considerable energy consumed and a plenty of CO2 emitted. This aggravates the energy crisis and incurs a substantial cost to the environment. As a result, the deep learning methods are difficult to be popularized and applied in the real smart grid environment. In this paper, to reduce training time, energy consumed and CO2 emitted, we propose a efficient green model based on convolutional neural network, namely LoadCNN, for next-day load forecasting of individual resident. The training time, energy consumption, and CO2 emissions of LoadCNN are only approximately 1/70 of the corresponding indicators of other state-of-the-art models. Meanwhile, it achieves state-of-the-art performance in terms of prediction accuracy. LoadCNN is the first load forecasting model which simultaneously considers prediction accuracy, training time, energy efficiency and environment costs. It is a efficient green model that is able to be quickly, cost-effectively and environmental-friendly deployed in a realistic smart grid environment.
