The invention provides a virtual power plant collaborative power grid planning method and system, and belongs to the field of power grid planning, and the virtual power plant collaborative power grid planning method comprises the steps: determining a planning line equivalent annual extension coefficient, a virtual power plant equivalent annual planning coefficient, an annual wind curtailment coefficient and a multi-infeed short-circuit ratio constraint based on the original data of a to-be-planned power grid; virtual power plant constraints are determined according to the rated storage capacity maximum value and the rated power maximum and minimum value of a storage battery configured for each node in the to-be-planned power grid, the maximum increase of each node in each time period in each typical scene, and the interruption load value; and based on the multi-infeed short-circuit ratio constraint and the virtual power plant constraint, establishing a power grid planning model by taking the minimum sum of th
