Photovoltaic power prediction method, device and equipment and readable storage medium

The invention belongs to the technical field of photovoltaic power generation, and discloses a photovoltaic power prediction method, device and equipment and a readable storage medium. The method comprises the following steps: carrying out similar day clustering on the weather forecast historical data and the weather forecast-photovoltaic historical data respectively; constructing an initial LSTMneural network model and an initial BP neural network model, and obtaining a plurality of types of LSTM neural network models and a plurality of types of BP neural network models through classification training of a plurality of types of weather forecast-photovoltaic historical data sets and a plurality of types of weather forecast historical data sets; determining a weather forecast-photovoltaichistorical data set and a weather forecast historical data set to which the weather forecast data of the to-be-predicted time period belongs; and obtaining a first photovoltaic power prediction resultand a second photovoltaic
