Power grid dynamic data model construction method

The invention relates to the technical field of smart power grids, in particular to a power grid dynamic data model construction method. An updating instruction is generated according to the interference degree of the environment on new energy, and power generation parameters are dynamically updated; constructing a power generation data analysis model for the updated power generation parameters to obtain an output evaluation index, wherein the index can objectively reflect the output performance and reliability of the new energy system; the monitoring capability of the new energy system is improved, and a scientific basis is provided for new energy scheduling decision making. Constructing a demand prediction model for each access node in the power grid to obtain an energy demand value of each access node, and comprehensively analyzing the energy demand value and the output evaluation index to perform new energy scheduling; effective utilization and supply stability of new energy are realized, balance between
