Embodiment 1
[0066] This embodiment provides a non-intrusive load decomposition method based on differential input strategy and neural network, the flow chart is shown in the attached figure 1 , the specific processing flow includes the following steps:
[0067] S1. First obtain the total real-time power X of each electrical appliance on the master meter, and at the same time acquire the real-time power Y of the target electrical appliance (target load) at the corresponding time.
[0068] S2. Calculate the differential information of the total real-time power X on the master meter, that is, calculate the real-time variation of the total power, and obtain the real-time power variation sequence Xd.
[0069] S3, using the power change sequence Xd as the input of the neural network model, and using the real-time power Y at the time corresponding to the target load as the output of the neural network model to obtain a training sample set;
[0070] S4. Using the training sample set to train the...
