【 摘 要 】

Fine-grained power data are used to characterize user's behavior in smart grid, Non-intrusive load monitoring can effectively separate the load of a single electrical appliance from the whole energy consumption of a dwelling, which is beneficial to fully exploit the load potential. In this paper, considering the relationship on usage habits among electrical appliances, the characteristics of energy consumption, we propose a multi-objective modeling method based on deep learning. The multi-objective model is constructed by CNN and LSTM, and the neural network is collaboratively optimized by multi-objective outputs. The experimental results show that the multi-objective model performs better than the other models on the five appliances, reducing the absolute error to less than 10 and the total error of the standardized signal to less than 0.1.
