Operating highly loaded grids in real time requires combining powerful topology optimisation with efficient handling of “linear” remedial actions. ToOp, developed by 50Hertz, is a state-of-the-art optimiser for topological measures, going beyond the topology optimisation currently available in OpenRAO.

In TopRAO, we couple ToOp with the Powsybl-based OpenRAO toolbox: OpenRAO optimises linear remedial actions (PST, redispatching, counter-trading, HVDC), while ToOp focuses on topological measures. Together, they form a real-time-capable RAO engine for security analysis at TSO and inter-TSO level.

This demo walks through an end-to-end workflow: importing network data, running joint optimization of topology and linear actions, and analysing resulting constraints, actions and costs using open, transparent components.
