Classification: CPC G  H  Y | IPC G

Claim 9:
10. A method of operating a power grid assisted by an artificial intelligence (AI) module, the method comprising, by at least one processor executing at least one program element:
during a first phase, generating a training data set that comprises a plurality of solutions of at least one security-constrained optimal power flow (SC-OPF) problem associated with at least one power grid scenario, the training data set comprising training input data and corresponding training output data, the training output data being the expected output when the corresponding input data is input;
during a second phase, training the AI-module by supplying the training data set to the AI-module; and
during a third phase, operating the power grid in a power grid scenario, the operation at least partly depending on SC-OPF problem solution output data obtained by solving a modified optimization problem that has a size that has been reduced by the trained AI-module in response to input data associated with the power grid scenario.
