Abstract:
The existing non-intrusive load decomposition algorithms often require a large number of electrical load data at equipment level to ensure the decomposition accuracy,but it is difficult to obtain these data due to the user’s consideration of privacy and high installation cost.Therefore,a time-series generative adversarial network which can deeply explore the time-series characteristics of power load data and the correlation of electrical appliances is constructed.The dimensionality reduction network is used to reduce the dimensionality of the high-dimensional vector composed of the active power sequence of all electrical appliances to reduce the computational complexity,and the result is restored to the high-dimensional vector through the restoration network.Based on the non-intrusive decomposition method of electrical appliance operation status and deep learning,the load decomposition regression model of complex-state electrical appliances is built by using the convolutional neural network-bidirectional gated recurrent unit,and the load identification and classification model of simple-state electrical appliances is constructed by using the deep neural network.The effectiveness of the proposed method is verified by comparing other data generation methods and the load decomposition results obtained by changing the proportion of the generated data in typical public datasets.
