The invention discloses a reactive capacity evaluation method and system for an electric vehicle charging station participating in power grid voltage regulation. Relates to the technical field of reactive capacity prediction. On the basis of the existing power grid voltage regulation technology, the method is improved, on one hand, the electric vehicle charging station participates in the power grid voltage regulation process, the reactive capacity of the electric vehicle charging station is evaluated based on power grid voltage regulation parameters, and the reactive support of the electric vehicle charging station is adjusted according to the reactive capacity evaluation result of the electric vehicle charging station; and on the other hand, in order to accurately obtain the reactive capacity of the electric vehicle charging station, the scheme also provides a corresponding reactive capacity iterative prediction model, and the reactive capacity iterative prediction model iteratively calculates the reactive capacity of the electric vehicle charging station on the basis of the electric vehicle charge capacity loss model and the electric vehicle charging demand model. And a high-precision data basis is provided for the electric vehicle charging station to participate in power grid voltage regulation.
