The CIGRE Science & Engineering paper by TenneT TSO, Artelys and TU Delft says GridOptions is a decision-support tool: it recommends topological remedial actions and the operator chooses the final strategy, possibly using information the tool lacks. Scope is limited to substation reconfigurations in part of the Dutch 110 kV grid (9 controllable substations, max three open busbar couplers); day-ahead inputs carry forecast uncertainty, dynamic security and AC calculations are not yet in the optimisation, and operators get a fixed shortlist updated roughly monthly. The current version uses no machine learning; TenneT's 2025 annual report describes researching ML and heuristics for it.
