The invention provides an economic dispatching method for a power distribution network containing multiple virtual power plants based on a static security domain, and the method comprises the steps: generating a static security domain in a corresponding power injection space based on a topological structure of the power distribution network; based on the generated static security domain, constructing a power distribution network economic dispatching model containing multiple virtual power plants; and on the basis of the constructed economic dispatching model of the power distribution network and a Karush-Kuhn-Tucker condition, dispatching the transaction electric quantity and the electricity price, and designing a collaborative operation strategy of the multiple virtual power plants and the power distribution network. According to the technical scheme, the technical problems that the sub-optimization problems are still complex and the calculation speed is low due to the fact that the variables in the constrai
