The invention discloses a method for calculating direct current access capability of a receiving end power grid with consideration of multiple constraints, belonging to the technical field of electric power system and automation thereof. The method for calculating direct current access capability of a receiving end power grid with consideration of multiple constraints comprises: determining an alternative direct current drop point set according to the station address condition of a transformer station, electric power balance and the like; determining newly increased direct current access drop points according to the short circuit capacity of each alternative direct current drop point in the typical mode and the interaction degree between each direct current in the typical mode; and giving the direct current access capability of a receiving end power grid through iteration after integrated consideration of multiple constraints comprising the direct current multi-infeed short circuit ratio, the power grid low ebb peak load regulation capacity, the relative moment of inertia index, the N-1 transient stability and the like. The method for calculating direct current access capability of a receiving end power grid with consideration of multiple constraints is beneficial to guidance of a power grid planning department about reasonable planning of the direct current drop points of the receiving end power grid, and can give the reasonable level for the direct current access capability of the receiving end power grid and reduce the blindness for direct current construction, and can improve the power grid operation control level.
