Summary: | The invention discloses an equivalent parameter calculation method and system for providing inertia support for new energy. The method comprises the steps that the power fluctuation state of a power grid is detected in real time; when it is detected that the power grid power fluctuates and the power grid frequency variation caused by the power grid power fluctuates meets a preset input condition, providing step-type power through the new energy station to carry out inertia support of the power grid frequency; and after the new energy station provides step type power support, calculating equivalent parameters of inertia support of the new energy station.
