An electrical grid, using physical operating data of the electrical grid a current operating status of the electrical grid is determined by way of a network model of the electrical grid is provided. A first grid component is controlled as a function of a control signal by a regulator with a grid-component-internal control circuit which is adjustable via control parameters. A first component model of the first grid component is imported to determine a dynamic reaction of the first grid component to the control signal depending on the control parameters.
