Method for the computer-aided control of the power in an electrical grid

The invention relates to a method for the computer-aided control of the power in an electrical grid. The electrical grid has a predetermined rated frequency and comprises a plurality of network nodes (N1, N2,..., N5) that are interconnected via power supply lines (PL), each of said nodes supplying power to or drawing power from the electrical grid. In addition, at least part of the network nodes (N1, N2,..., N5) are provided with proportional controllers, for which a reference power (P10, P20,..., P50) and/or a proportionality factor (k1, k2, k5) can be set and which control the power that is supplied by or drawn by each network node (N1, N2,..., N5) in accordance with the difference between the frequency of the voltage in each network node and the rated frequency of the electrical grid. In the method according to the invention, the reference power (P10, P20,...,P50) and the proportionality factor (k1, k2, k5) of at least some of the proportional controllers are determined in a suitable manner on the basis of solving an optimization problem. The operation of the electrical grid with respect to stability and robustness is optimized in accordance with the optimization problem, without the need for carrying out complex simulations.
