Microgrid intelligent control method and system

The invention provides a micro-grid intelligent control method and system, and belongs to the technical field of intelligent power grids, and the method specifically comprises the steps: obtaining a power waveform of a grid-connected point of a micro-grid in a preset time period, and determining the power quality of the grid-connected point according to the fluctuation data of the power waveform when determining that the power quality of the grid-connected point meets the requirement; the method comprises the following steps: determining the off-grid switching times with power utilization gaps according to the power utilization gap conditions of power consumers with different off-grid switching times, and taking the off-grid switching times as gap switching times to obtain historical power consumption of different power consumers of the micro-grid; the minimum energy storage threshold value of the energy storage device of the micro-grid is determined by combining the power utilization gap quantity of differen
