Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0032] Such as figure 1 As shown, a short-term electricity price prediction method based on BP neural network and Markov chain includes the following steps:
[0033] (S1) Establish a BP neural network model for short-term electricity price prediction and make preliminary predictions to obtain the predicted value of electricity price; the input variables of the BP neural network model are the electricity value and load value at the same time the day before the predicted time, and the two days before the predicted time The electricity value and load value at the same moment, the electr...
