The invention discloses an operation and maintenance
analysis method, device and equipment for a
virtual power plant and a medium, and the method comprises the steps: obtaining structured
time series data, text data and image data generated in the operation and maintenance process of the
virtual power plant, and carrying out the
feature extraction of the multi-
modal data, and obtaining a multi-
modal fusion feature; and then, inputting the multi-
modal fusion features into the constructed causal enhanced multi-agent fault diagnosis framework for reasoning so as to determine the fault
root cause and the propagation path thereof of the
virtual power plant. And meanwhile, an equipment health state evaluation model based on meta
reinforcement learning is constructed, the model is combined with the multi-modal fusion features and the dynamic
knowledge graph, the health state of the equipment in the
virtual power plant is evaluated, and corresponding
maintenance actions are output. The accuracy and practicability of operation and maintenance analysis of the
virtual power plant can be improved, and the operation reliability, economy and flexibility of the
virtual power plant in a complex
power grid environment can be enhanced. The method can be widely applied to the technical field of
electric power.
