Method for the computer-assisted configuration of an electrical power grid

A method for a computer-assisted configuration of an electrical power grid having a plurality of grid nodes, comprising:

• providing a control unit,
• providing one or more first grid nodes connected via power lines,
• wherein the one or more first grid nodes are operably connected to the control unit,
• wherein the one or more first grid nodes provides active power for a load in the power grid during operation of the power grid,
• wherein a respective first grid node of the one or more first grid nodes is a grid-forming producer node in which an amplitude and a frequency of a voltage in the respective first grid node are controlled, on a basis of a reactive power fed in by the respective first grid node or the reactive current fed in by the respective first grid node and, on a basis of the active power fed in by the respective first grid node or the active current fed in by the respective first grid node using a control method,
• providing one or more second grid nodes which provide active power for the load in the power grid during operation of the power grid,
• wherein a respective second grid node of the one or more second grid nodes is a grid-supporting producer node in the form of a regenerative energy production plant in which, the active power fed in by the respective second grid node or the active current fed in by the respective second grid node and the reactive power fed in by the respective second grid node or the reactive current fed in by the respective second grid node are controlled on the basis of the frequency and amplitude of the voltage in the respective second grid node using the control method,
• wherein:
• the control method comprising:
• determining changes in the active power of the respective first grid node for respective predefined changes in the active power of the load on a basis of a dynamic model of the power grid, wherein the dynamic model describes temporal changes in variables of the power grid, including voltages, powers, and frequencies;
• determining changes in the active power of the one or more second grid nodes for respective predefined changes in the active power of the load on the basis of the dynamic model of the power grid;
• and
• adjusting the control methods for the respective first grid node and second grid node in such a manner that an optimization problem with an aim of operating the power grid in an optimum manner with respect to one or more optimization criteria is solved using the determined changes in the active power of the respective first grid nodes and the second respective grid node,
• wherein the aim of the optimization problem is for as little of the active power provided for the load as possible to come from the one or more first grid nodes.
