The invention provides a micro-grid group optimization control method and system based on an aggregation splitting mechanism. The method comprises the following steps: acquiring the total power generation amount of a supply side and the total consumption amount of a demand side of each micro-grid in a day-ahead preset time period; aggregating the micro-grids of which the difference value between the total power generation amount of the supply side and the total consumption amount of the demand side is greater than or equal to a preset threshold value to obtain an aggregated micro-grid group; and constructing an optimal control model with the highest total bidding benefit of the micro-grid group, obtaining the optimal bidding control quantity of each micro-grid according to the optimal control model, and carrying out unit operation feedback scheduling control of each micro-grid according to the optimal bidding control quantity. According to the method, the power market rule and the power system constraint can
